History ThereIsNoKillLikeOverkill / VideoGames

* ''VideoGame/EternalChampions'' had overkill moves that were specific to each stage: if you can defeat your opponent and get their body to fall on just the right spot, they'll be chopped up by a fan, or fall into a vat of acid, or get impaled on the Washington Monument, to name a few. The Sega CD remake also added a second form of Overkill and featured more standard [[FinishingMove Vendettas]], which were always overly bloody. One of the simplest, but most brutal one was where the character would pull out a knife, and stab his opponent ''until the screen faded out''.
** Also in the UsefulNotes/SegaCD version were the "Cinekills", in which the defeated fighter is teleported to the Dark Champion's realm, where the Dark Champion personally executes the defeated fighter, in cutscene form. However, it is difficult to pull off a Cinekill.

* Torgue is adamant about destroying laser guns in ''VideoGame/BorderlandsThePreSequel'' because [[DisproportionateRetribution they don't explode]]. At one point, he sends fifty barrels of high explosives crashing down on a laser rifle, via spaceship, so it explodes the bridge it is on and makes it fall into a river of lava. Keep in mind: this was to destroy ''one'' laser rifle.
* This occurs almost constantly in ''VideoGame/OrcsMustDie'' and its sequel. You create hallways of death through which the hapless orcs have to run. While doing so, they are subjected to your traps which do things like crush, burn, slice, dice, pulverize, catapult, explode, crush (from the side), shred, impale, and dissolve (among other things). Though there are some larger enemies (especially in the sequel) that can survive multiple traps, the standard orcs do not and are usually reduced to LudicrousGibs with one trap. Because they come at you in massive waves, there are orc bits flying around almost constantly.
* ''VideoGame/AmericanConquest'' has this relation with even the most primitive firearms — a matchlock arquebus deals about three times more damage than even the strongest units may take. And then you have muskets and fusils — the latter can be even upgraded to inflict One Hit Polykills in case you have another target right behind the first one. The only thing that prevents firearms from being outright GameBreaker is their inherited inaccuracy and relatively slow reload — at least for earlier types.
* One example is ''Black Belt'' for the UsefulNotes/SegaMasterSystem. After you beat most bosses your character will continue to beat the living crap out of them. Considering that Black Belt is, in Japan, originally an adaptation of ''Manga/FistOfTheNorthStar'', this [[YouAreAlreadyDead hardly comes as a surprise.]]
* In ''VideoGame/FightNRage'', you can keep attacking the enemies after they were defeated, and if they receive enough damage, [[LudicrousGibs they will explode in a rain of bones]]. This will give you extra points, and it's mandatory to earn more extra lives on higher difficulties.
* In the ''VideoGame/GranTurismo'' series, you can enter races meant for lightweight sports cars with a ''freaking Le Mans prototype car!'' [[note]]You can no longer do this in ''Gran Turismo 6'' with the PP system put in place to make sure that the car you enter a race with is in the same class as the opponents.[[/note]]
* In ''VideoGame/JustCause 2''... Let's just put it this way. You have options. Sure, you can shoot a guy in the head with a revolver, but where's the fun in that? Why not attach his military jeep to a helicopter and drop him from a mile high, Blues Brothers style? Or throw him out of the jet plane he was piloting, attach him to it using a grappling hook, and then crash the entire thing into a military base for bonus points?
** Some of the mods available for this game take this up to eleven. Take for example the Jet Propulsion Gun, a DLC weapon that knocks people a fair distance and flips cars over. One of the mods increases its power massively, so instead of knocking people off their feet, it sends them into a low-earth orbit. See also the Rocket Launcher mod which increases its rate of fire, and makes the explosions cause everything within a mile of the explosion to die instantly (including you).
* ''VideoGame/HalfLife2'' actually lampshades this in one of Dr. Breen's speeches.
--> "''You'', on the other hand, will be destroyed in every way it is possible to be destroyed, and even in some which are essentially ''[[BeyondTheImpossible impossible]]''!"
* In ''VideoGame/RuneFactory3'', you can continue to hit a dead enemy if they are knocked into the air. You can do this for hours if you want. Additionally, while in wooly form, you can grab a dead enemy to perform a [[FinishHim fatality]] on them.
* One of the oldest examples is ''VideoGame/ScorchedEarth''. Nukes, Plasma Blasts, Hot Napalm, the Funky Bomb, and the aptly-named Death's Head. Quite capable of destroying large sections of the map, especially with the explosive sizes on maximum in the game's configuration. The Death's Head is so devastating that if fired wrong it can kill everyone on the screen. Including the player who thought firing it was a good idea.
** The second biggest overkill weapon, the funky bomb, when it lands, sends out up to 10 other bombs in random directions. It then explodes one more time the size of a baby nuke. Unless the target has really good shields, it is ''not'' surviving that one.
** Also, when a tank dies, it has a chance of exploding into a funky bomb or causing a missile explosion. And then a baby nuke explosion. And THEN an explosion the size of a nuke. Combine this and the funky bomb explosion and simply killing someone with a baby missile can set off a chain reaction that can wipe out the entire map with explosions set to max.
* Before them all came ''VideoGame/{{Turok}}''; a series of games that lived and breathed this trope. The original game had the ''quad-rocket launcher'', [[ExactlyWhatItSaysOnTheTin which fired off four]] [[MoreDakka high explosive missiles at once]] — and it was one of the ''weaker'' weapons in your inventory. The ''fusion cannon'' was basically a tactical nuke-cross-{{BFG}} that decimated everything within a square-kilometre in a bright red flash. The… You know what? [[https://www.youtube.com/watch?v=5sIDUv4RtGg Just watch this]].
** Its sequel, ''Turok 2: Seeds of Evil'', actually managed to ''top it''. Because hunting dinosaurs requires heavy firepower. Aside from the usual final-game devastators, a particular mention goes to the Cerebral Bore, which fires shots that embed themselves in your enemy's skull. Then they start ''drilling''. Then they [[YourHeadAsplode explode]]. One-shot-kill everything.
*** Moreover, Turok really doesn't do any hunting himself (though some dinosaurs do attack, and some are actually armed later on), but rather, he fights many humans clearly designated as hunters/poachers. That's right. Turok carries enough firepower to hunt people who have enough firepower to hunt dinosaurs.
* ''VideoGame/CommandAndConquer'':
** The games thrive on this trope. Whether it's constructing an army half the size of the map, sending said army against one particular enemy or structure, to the units such as double-barreled tanks (Mammoth and Overlord), nuclear cannons and trucks, and an orbital laser. ''Generals'' ramps things up with faction generals that specialize in a particular aspect of their army, and that includes a nuclear general, a laser general, and an explosives general. Then there's a secret general in the Challenge mode who has access to all superweapons; she introduces herself by firing every superweapon simultaneously at a column of tanks.
** Just wipe out the majority of your enemy and decide to leave his Construction Yard barely intact with a little HP left? The perfect solution is to move your troops away, then launch your superweapon at the opponent's Construction Yard. Nothing quite so satisfying like kicking someone to the curb like that.
** The canonical ending for ''Tiberian Dawn'' requires the GDI commander to do that to the Nod Temple — unlike in the [[StoryAndGameplaySegregation videos, in the actual gameplay]] a single Ion Cannon blast ''can't'' destroy a Temple… and the Brotherhood repairs the Temple quickly enough that by the time the Ion Cannon has reloaded, the Temple is fully repaired.
** Hell, even the superweapons need a special mention — the GDI superweapon in the third is not one, but [[NukeEm EIGHT lasers fired at once from outer space]]. You can write your name on your enemy's base… [[KillSat with Particle Cannons]].
** The "Command & Conquer: Retarded" GameMod makes ''everything'' overpowered. The nukes, for instance, now have three times the power ''and'' area of effect.
** The Shogun Executioner in ''VideoGame/CommandAndConquerRedAlert3'' — a giant tripod with three bodies, each of which is armed with a LaserBlade. It's also healed by electricity, and many of your enemies in this level are armed with [[LightningGun Tesla coils]]. Oh, and it's tall enough to knock helicopters out of the sky just by walking into them. You ''can'' lose it, though, if you're not careful.
** Used for Drama in ''Tiberium Wars'' when Director Boyle authorizes the use of a Liquid Tiberium Bomb against the Scrin. General Granger (your commanding officer) notes that it is still possible to win through conventional methods and that [[PyrrhicVictory the Bomb would have irrecoverable consequences if you use it in such a high-saturated tiberium zone]]. Sure enough, if you choose to use the bomb, not only is every single soldier under your command killed, but also several innocent people in yellow zones across the earth. Red Zones also spread to unprecedented levels, leaving much of the world either homeless or dead, all to take out what was later revealed to be nothing more than ''a worker fleet''.
** In the final mission of ''Tiberium Wars: Kane's Wrath'', you get control of all three factions of Nod at once. This means you could build ''three'' copies of the Redeemer Epic unit when a single one would be more than enough to finish the mission, not to mention combining the best units from each of the armies. Unfortunately, by this point in the mission, you'll likely have destroyed most of the opposition and a timer countdown to failure would have also started (Kane specifically sends you these forces because the Macguffin is about to implode and you need to leg it), so there's not much to use the massive army on.
* In ''VideoGame/ArTonelicoIIMelodyOfMetafalica'', this happens when you use 100 I.P.D. Replekia Amplification with [[GameBreaker Phantasmagoria]] song magic. How does three billion damage sound? (The FinalBoss has 150000 HP).
* ''VideoGame/GearsOfWar 2'': Single enemy infantry who has been incapacitated? ORBITAL LASER. Overall there is a ridiculous number of methods to reduce enemies to {{chunky salsa|Rule}}, and even more to execute downed enemies.

** Famously inverted [[https://www.youtube.com/watch?v=KS7hkwbKmBM by Daigo Umehara]].

** In addition, Akuma players especially like to finish off opponents with his Shun Goku Satsu move (Translates to "Instant Hell Murder") which is possibly one of the most satisfying, and most predictable, moves in fighting game history. Pulling this off results in a ''giant burning 'Ten' symbol'' covering the screen in addition to the standard 'Flash', mirroring the one on Akuma's back. Taken to its logical conclusion by [[https://www.youtube.com/watch?v=wzDxLUcji3Y&t=1m55s Tokido]].

* In the FirstPersonShooter adaptation of ''TabletopGame/{{Shadowrun}}'', after you kill an opponent, you have to continue to shoot their body until it [[EverythingFades vanishes]] to keep them from [[DeathIsNotPermanent being resurrected by a teammate]].
* In the ''VideoGame/KnightsOfTheOldRepublic'' RPG game, Darth Malak orders the orbital bombardment of Taris, killing 6 billion people in a failed attempt to kill one person! All because the search for them was taking "too long."
** In an odd twist of fate, he was ''right'' that it was taking too long; unfortunately, he realised this too late to actually stop them.
* Certain ''VideoGame/NeedForSpeed'' games let your cars having ''massive'' advantage over other cars if they don't have wacky RubberBandAI. In that case, expect you to lap anyone before reaching the finish line.
* In the UsefulNotes/XBox remake of ''VideoGame/NinjaGaiden'', it's easy as pie to keep comboing a dead and decapitated foe with the [[EpicFlail Vigoorian Flail]] until the poor sucker finally disintegrates into a cloud of red dust. It's harder but more satisfying to do it with other weapons.
** In the sequel, the evil spider clan ninjas and evil fiends that you fight [[{{Determinator}} will keep attacking you even after they've]] ''[[OnlyAFleshWound lost a limb.]]'' Therefore, Ryu has a new [[FinishingMove obliteration technique]], which in most cases will take off a few more limbs and usually a head (just to make absolutely ''sure'' they're dead).
** The Obliteration Techniques themselves are a rather ridiculous example of this trope, seeing as how you can do them on an enemy who's been ''decapitated'' just so long as the body hasn't fallen down yet.
*** Justified, as some enemies are demons, and are therefore [[LosingYourHead not particularly bothered by the loss of their head]].
* In ''VideoGame/TheOutfoxies'', [[spoiler:this is how the final boss is defeated: after destroying their helicopter, Mr. Acme falls onto the roof of his home. Mrs. Acme, his rotund wife, falls on top of him, driving his health bar down to a small sliver. That sliver is shaved off when [[HumiliationConga his helicopter crashes on both of them.]]]]
* In ''VideoGame/SamuraiShodown'', defeating the foe with the right move (usually the strongest slash a character has, but there are some exceptions) will cause them to be bisected and golden charms to fall out, leaving only their weapon in the ground.
** ''Samurai Shodown'' gets worse than that. In IV, at least, if you defeat your opponent by a lot and finish with a strong attack, you can perform a "final" attack that will cut them into pieces with blood graphically spurting out.
*** It gets even worse: In the original version of ''Samurai Shodown V Special'', you could, under certain conditions, perform a (very violent and graphic) move called the "Zetsumei Ougi" which would actually kill your opponent (thus ending the match); the relevant part is that, for a number of characters, it went beyond just cutting the opponent up: some of them would literally destroy the opponent's body leaving nothing behind, save perhaps a head, a skull, or a rain of blood. [[https://www.youtube.com/watch?v=6buTbwWTWbo See here]].

* ''VideoGame/StarWarsBattlefront'' has a few examples, especially using an AT-AT to step on people and using AT weapons against infantry. The command classes in Battlefront 2 are good examples; the Imperial Officer and the [=MagnaGuard=] have grenade launchers, the [=MagnaGuard=] also has a rapid-fire rocket ''pistol'', the Clone Commander has a man-portable heavy machine gun, and the Bothan Spy can turn invisible and has an incinerator.
** The Special classes also count; the Destroyer Droid has machine guns and an energy shield. The Wookie has twice the health of normal infantry and has the bowcaster, which can shoot a shotgun-like burst that can easily kill at close range but can also charge up to fire a powerful shot that will take out nearly any enemy trooper. It also has a two-level zoom scope for sniping with the charged-up shot, as well as a grenade launcher for a secondary weapon. The [[VideoGame/DarkForcesSaga Dark Trooper]] has a lightning gun that can kill four soldiers at once. The Jet Trooper has an EMP rifle that can one-hit-kill anything but main battle tanks and Jedi, and the last two have jet packs.
** The award upgraded rocket launcher allows a Vanguard to stand back and snipe infantry with short-range anti-tank cruise missiles.
** The fan-made maps "Capital Ship Down" 1 and 2 are very good examples of why the second game left out the infantry maps with starfighters on them. A Y-wing can take down an AT-AT in two hits if they are carefully placed, and the bombs have an insane blast radius when used against infantry.

* At the end of a game in ''VideoGame/TeamFortress2'', the losing team are rendered unable to use their weapons, with their speed decreased by 10%, and the winning team have their critical hit ratio increased to maximum. Also, the losing team's spawn area (normally the only safe area for them on the map) becomes accessible by the opposing team. If the server settings are particularly mean, the losing team can still respawn in that phase, only to be killed again by the winners.
** The Spy's Backstab is meant to be a OneHitKill. To make sure it always is a one-hit kill, Valve gave the Backstab the ability to always deal damage equaling twice the target's maximum health. And since it's a guaranteed CriticalHit, which triples the already high damage, you're doing damage equal to ''6 times the enemy's max health''. Getting a backstab on a Heavy does an absolutely ridiculous 1800 damage on an enemy that has 300 health (sometimes 450 health).
*** And if you manage to back-stab someone while they are in mid-air, their body will go flying at extreme speeds until it hits a wall or tumbles to the ground.
** The Half-Zatoichi can deal 600 damage if the player hits an enemy wielding the same weapon. This means a Demoman can one-shot a Soldier in the front with a crit sword attack for the same damage as a full health Heavy Backstab.
** Most weapons feature a "taunt kill". It causes 500 damage caused by the following: an ultra-strong bat swing, a kamikaze grenade attack, a Hadouken, a point-blank flare to the face, a ring of fire, a sword swing that is full of honor, a finger gun, getting hit in the head by a guitar, a robotic hand spin inside your guts, a stab from a saw, a stab from an arrow, and a fencing with a butterfly knife.
** And then there's the infamous x10 mod, which is best described as "Overkill: the GameMod." As the name suggests, the mod takes the attributes of every weapon in the game and multiplies them by ten. Rocket launchers that fire [[MacrossMissileMassacre thirty rockets at once]], knives that stab about ten times a second, Demoknights that can charge across an entire map and ShieldBash for several hundred damage… you get the idea.
*** You thought x10 was overkill? Wait until you see x20! Or x50! x100! And yes, [[SerialEscalation it goes further and further]].

*** Overkilling in both effect and length of cutscene is Sephiroth's [[https://www.youtube.com/watch?v=hTc9sLmOR0A Supernova]]. He summons a fiery ball of destruction which destroys Pluto, Saturn, and Jupiter before slamming into the Sun, causing it to erupt and swallow Mercury and Venus and tear apart the Earth! The animation takes two minutes, he can summon it multiple times in the same fight (destroying the Solar System each time), and you '''cannot''' skip the animation. Due to the games' mechanics, it won't actually kill the heroes.

*** [[https://www.youtube.com/watch?v=XZbfDMzynwg&feature=related Eden]]. Nothing says 'overkill' like shooting your enemy with a beam that blows up the next galaxy.
*** The attack [[https://www.youtube.com/watch?v=79ZCWLsmS4E Great Attractor]] of the final boss Ultimecia draws several planets and debris from orbit and smashes the whole party with it.

*** Espers. There are two Esper's with out-of-this-world {{Limit Break}}s: [[https://www.youtube.com/watch?v=gLuXBb5HZ0M&t=9m17s Ultima and Zodiac]].

* While it's referred to as "Overwhelm", wiping out the entire enemy party in a single turn, without giving them the chance to strike (or negating all their attacks) and hitting their weak point nets you more of a Macca Bonus in ''VideoGame/DevilSurvivor''.
** Start a NewGamePlus. Bring out your endgame demons and use their most powerful attacks, and enjoy the five-digit damage. ''On low-level demons.''
* In ''VideoGame/{{Drakengard}}'', the weapon levelling system encouraged the player to continue slashing enemies long after their health ran out. Consecutive hits would increase the experience one obtained from defeating enemies.
* Many networked FPS games (like ''VideoGame/UnrealTournament'') allow you to get LudicrousGibs from shooting fallen foes enough or blasting them. This behavior is encouraged in some by the ability of enemy medics to revive them.
** "Jailbreak" for ''Unreal Tournament'': When the enemy team is captured, the execution is, most of the times, real Overkill. In one map in space, each team's jail had 5 vertical tubes, and when the entire team was captured, the 5 tubes opened and 5 Redeemer warheads fell on the room, exploding simultaneously and turning the unfortunates into molecules and some flesh bits. The other one had big fans in each jail, ready to slice the losers to death.
** Also, The Nail Weapons II X weapon pack for [=UT99=], and the Redeemer, which tends not to even leave chunks, let alone a corpse.
** The Unreal Tournament games are famous for several [[GameMod mods]] that turn this trope to eleven. [=Unreal4Ever=], for instance, is nothing ''but'' ridiculously overpowered weapons, from one that makes your enemy explode in a giant fireball that kills anyone else nearby to one that makes blasts several times as large as the Redeemer's, to one that makes black holes that can suck the entirety of a small level's worth of foes in them and then explode. Game balance? What game balance?
* ''Franchise/{{Metroid}}'':
** ''VideoGame/MetroidFusion'': In order to truly ensure the extinction of the X parasites, Samus can't rely on the Biologic Space Labs station's [[SelfDestructMechanism self-destruct systems]] alone; [[spoiler:the only way to make sure they're absolutely wiped out is to deorbit the station with the self-destruct on a timer, and thus ColonyDrop the station far enough into [=SR388=]'s atmosphere to set up a [[EarthShatteringKaboom planet-nuking chain reaction]]. Partially justified in that a station dedicated to biological (biological weapons?) research would have to guarantee that the station's remains were sterilized as well as destroyed, hence the absurdly powerful SD system.]]
** A more personal example occurs in ''VideoGame/MetroidPrime3Corruption''. During the fight on Norion, Samus free-falls down a sixteen-kilometer-deep generator shaft in pursuit of [[TheDragon Space Dragon]] and series RecurringBoss Ridley. After administering a long-distance thrashing with beam and missile weapons, she lands on his head, pries his jaws open, and jams her cannon arm down his throat before firing several more rounds "down the hatch."
** In ''VideoGame/SuperMetroid'', [[BrainInAJar Mother Brain]] tries to kills Samus with her Laser Brain Attack when [[HPToOne the Hunter's HP is nearly zero]]. But then she ends up on the wrong end of another such smackdown when she murders the infant Metroid from ''VideoGame/MetroidIIReturnOfSamus''/''VideoGame/MetroidSamusReturns'' and earns herself a Hyper Beam-fueled RoaringRampageOfRevenge from the creature's [[MamaBear human adoptive "mother."]] The final shot decapitates Mother Brain, exploding her cybernetic combat body; her severed head turns to gray powder as it hits the floor.
** ''VideoGame/Metroid1''/''VideoGame/MetroidZeroMission'' concluded with Mother Brain's self-destruct timer blowing up the Pirate base, but leaving the surface intact. But since that failed to kill Samus, in ''Super Metroid'' the self-destruct causes a massive, [[EarthShatteringKaboom Zebes-Shattering Kaboom]].
** In a straighter example, killing any regular {{mook}} with your most potent weapons (such as the missile combos in the ''VideoGame/MetroidPrimeTrilogy'' — which include a flamethrower, an ice bomb, and a ''black hole'', among others).
* Enemies and characters killed in ''VideoGame/EnchantedArms'' stick around for three turns, during which time they can be resurrected. If, however, they are killed by inflicting more than double their total health in one attack, they disappear instantly and can't be resurrected until the end of the combat.
* In the shooter ''VideoGame/CallOfJuarez'', Reverend Ray can initiate a BulletTime mode at will, causing you to draw your six-shooters and have your crosshairs go towards the center from left and right… allowing you to practically kill an enemy, use the BulletTime, and then unload 12 bullets in them.
* The expansion pack for ''VideoGame/AgeOfMythology'' allows the player to create a Titan (i.e. a ''god''). They cost almost as much as a Wonder and take almost as long to construct (i.e. a shit-load of time and money), but watching an unstoppable hundred-metre-plus-tall engine of destruction effortlessly carve through enemy armies and bases is extremely satisfying.
** Unless you actually target the enemy base, the titan will just fall to attrition, as it will constantly attack units if they attack them, meaning if you continuously make and send just one unit at the titan at a time, it will eventually die with you little closer to defeat. It'll still cost a lot of resources, though…
*** [[PuzzleBoss Titans have no anti-air defense.]] Air units with an attack are hard to come by — the Atlanteans have Stymphalian Birds, the Egyptians have Phoenixes — but [[GameBreaker game-breaking]] if you plan to get them.
*** [[GameBreaker Hecate's research for the Atlanteans that gives all myth units a]] HealingFactor permits you to create a ''regenerating'' Titan. Those things are ''bloody'' hard to kill.
* ''VideoGame/SuperRobotWars'' games can sometimes encourage this by giving "Dynamic Kills" to certain attacks; if they deal enough damage to kill, the animation will change to integrate the enemy's destruction, for instance having a super-powered punch drill straight through the target, or an energy blast's explosion keep burning until there's nothing left. One of the first instances of this was Anime/{{Daitarn 3}}'s Sun Attack. If the attack will just harm but not destroy, the attack is simply a big blast of energy. If it ''will'', it's actually the blast carving a hole out of the enemy, and Daitarn drop-kicking the "plug" out. As the series progressed, more were introduced until it became mandatory for at least every "lead" robot of a series to have a minimum of one Dynamic Kill.
* ''VideoGame/DwarfFortress'' features several levels of overkill, especially in Fortress Mode, ranging from champion macedwarves playing Goblin Golf to weapon traps each equipped with ''ten steel [[ChainsawGood large serrated discs]]'' (each of which hits three times per activation) to [[{{LetsPlay/Boatmurdered}} flooding the world with lava]] to kill one [[DemonicSpiders elephant]]. And if you can think of a better one, go ahead and try it out, chances are it's perfectly possible.
** And in [=DF2014=], you can hammer body parts to the point of being pulped outright, which [[ChunkySalsaRule predictable results]] if it's something the target needs to live. Subverted in the case of undead, which were ([[OurZombiesAreDifferent once again]]) changed, such that pulping body parts is required to put them down properly.

* ''VideoGame/EmpireAtWar'' allows you to build the Death Star and use it in space combat. Destroying the planet means that there is no ground conflict, allowing you to control the planet just by winning the space battle.
** The ''Forces of Corruption'' expansion takes it one step further by allowing you to build the Death Star II, which not only can destroy the planet, but also fire on enemy capital ships and space stations during battle! It also allows the empire to get the Executor, a Super Star Destroyer bigger than the screen at normal zoom, that carries more weapons than a space station and can deploy ''eighteen'' fighter squadrons; it can often take any but the biggest rebel or Consortium fleets on its own. And to add insult to total destruction, it only costs 3 pop cap, the same as a frigate. In other words, it's a {{Gamebreaker}} extraordinaire.
* Recurring [[BonusBoss Optional Boss]] Iseria Queen from Creator/TriAce's games is almost inevitably based around this — of course, since she's a boss, ''you'' are at the receiving end. Perhaps the best example is her appearance in ''VideoGame/ValkyrieProfile''... her standard attack is a 25-hit combo, each strike dealing damage above your characters' Max Possible HP. Don't ask about her Special Attacks.
** Not that ''VideoGame/ValkyrieProfile'' expects the player himself to raise this trope to a philosophy for the duration of gameplay. "[[FinishingMove Soul Crush]]" indeed.
** ''VideoGame/ValkyrieProfileCovenantOfThePlume'' allows you to drop an opponent's HP to zero, continue to unleash the rest of your attacks, and then hammer them with four [[LimitBreak finishing strikes]]. And this is a core game mechanic.
** And if you ''don't'' regularly indulge in massive overkill, Hel herself gets enraged and sends in horribly powerful monsters as punishment. Attacking efficiently is ''a very bad idea'', so much did the designers love overkill.
* Pretty much the logic behind the Bloody Mess perk in the ''VideoGame/{{Fallout}}'' series (only in ''VideoGame/{{Fallout 3}}'', ''[[VideoGame/FalloutNewVegas New Vegas]]'', and ''VideoGame/Fallout4'') does it actually provide any benefits). Normally, when an enemy dies, they fall down, possibly losing the last body part you shot at. With Bloody Mess, other body parts will fall off for absolutely no reason. There's nothing quite like detonating a super mutant by ''punching it''.
** ''Fallout'' incorporates many weapons designed for overkill fanatics. The original ''VideoGame/{{Fallout|1}}'' sported a rocket launcher, a [[MoreDakka minigun]] (and a laser variant), and a turbo plasma rifle (which is the most powerful weapon in the game overall); ''VideoGame/{{Fallout 2}}'' had new fun toys such as the H&K [=G11E=] (the best submachine gun for Small Guns users), the Vindicator minigun (an even stronger minigun), a pulse rifle (which is even stronger than the turbo plasma rifle and causes electric death), and a secret HolyHandGrenade (deals area damage of 300-500, enough to kill many enemies 3 times over); ''Fallout 3'' has the infamous Experimental MIRV, an improved Fat Man that fires 8 mini-nukes simultaneously in a wide spread.
*** Speaking of the Fat Man, it's quite possible (and just about every player will try this at least once) to catapult a mini-nuke into an enemies' ''face''! Seen [[https://www.youtube.com/watch?v=OzV1GlDDlv8 here]] (at about 0:38) in the trailer for ''VideoGame/{{Fallout 4}}"
*** The unique Fat Man called "Big Boy" can fire 2 mini-nukes at the cost of one. give it the MIRV mod and it will fire 16 for the cost of one. Questions need being asked if something survives that.
*** The Fat Man example is diegetically encouraged in the Reunions quest of ''Fallout 4''. The armory of Fort Hagen, which is trivially easy to get into if you scrounged around the dungeon proper, contains one Fat Man and one mininuke, and you find it right before you face [[spoiler:Kellogg, the man who killed your spouse and kidnapped your son, who laughs at your helplessness in getting him back]]. Said boss appears in a room that is just wide enough that a mini nuke shot around the far side of it will fry him and his minions while leaving you unharmed. Considering [[PapaWolf the current]] [[MamaBear mentality]] of the player character at the time, one can easily picture them literally nuking the room the moment the boss is finished taunting them.
** Even without the Bloody Mess perk it was possible in ''Fallout 1'' and ''2'' to finish off someone with a burst from even a modest submachine gun from point-blank range, which would literally rip his upper torso apart.
** Gauss weapons are great for dealing with armored targets like robots. The Gauss rifle is the logical step up, and both the pistol and rifle are from ''Fallout 2''. But ''VideoGame/{{Fallout Tactics|BrotherhoodOfSteel}}'' takes things towards the logical extreme with the gauss minigun, which has fairly long range for a minigun, tears through huge groups of (high-powered) enemies like they were nothing, and is more powerful than the Browning M2. [[TooAwesomeToUse It also eats ammo like popcorn, so you'll be saving it for the endgame.]]
** If you fight Ulysses in the ''Fallout: New Vegas'' "Lonesome Road" DLC, he will pull this on you, being smart enough to know that the Courier won't go down in a one-on-one fight. He brings regenerating Eyebots and convinces the [[AndIMustScream Marked Men]] into the fray to make sure you don't get out and have revenge.
** ''New Vegas'''s DLC, ''Gun Runners' Arsenal'', adds a challenge in which the Courier must kill an unmutated animal (some of the weakest enemies in the game) with either a mini-nuke or a mine built using one. It's appropriately called "Overkill".
*** Likewise, you can invoke this by reverse pickpocketing a Fatmine onto an NPC. You don't have enough time to outrun the blast radius, so if ''you'' survive the explosion, good luck with finding anything left of the corpse.
* In ''VideoGame/SupremeCommander'', there's nothing like inundating your opponent's base with Tier 3 stationary cannons situated on the other side of the map, watching as their shields collapse and their buildings explode… unless it's queuing up a bunch of nuclear warheads that overwhelm their anti-missile defenses and reduce their base to a lifeless smoking crater.
** In some cases, this isn't really ThereIsNoKillLikeOverkill so much as you ''must'' have twice as many nukes simultaneously striking the target as the enemy has strategic missile defense silos ''plus one'' in order to hit, because each defense can shoot down two incoming missiles before impact… though that doesn't stop you from building many more silos [[Film/{{Aliens}} "just to be sure"]].
*** To realize the true scale of Supreme Commander's overkill, you must also know that stationary nuke launcher deals 75000 damage[[labelnote:note]]Experimental nuke deals ''1000001 damage''[[/labelnote]] which only two experimentals can survive (as for Forged Alliance while little to no people play vanilla), and most other units do not have even half of this much health. Especially usual targets for nukes — bases with factories and resource production buildings which all are less than 10000 hp, and toughest regular units are battleships with about 50000 hp depending on faction.
** And the true overkill comes with the aptly named game-ender experimentals. They cost about as much as 20 'regular' experimentals. Even a single experimental is a threat to most bases, and if your opponent has the same amount of resources as you have but used them to build the cheaper experimentals, [[AwesomeButImpractical he'll have overrun your base long before your game-ender is done]]. But oh, [[CurbStompBattle what fun if you can get one of them deployed]]. To wit: An even more powerful artillery cannon than the tier 3, which can hit anywhere on the map with perfect accuracy, a mobile artillery installation that fires one round across the map per second, an artillery cannon that shoots one shot per 3 seconds which splits up into 6 projectiles, who each split up in 6 more projectiles, and a nuclear missile launcher that builds nukes very fast, for free, which take 2 countermeasure missiles to kill, and do 10 times more damage than the strongest unit can take in a huge radius. Oh, and there is one experimental building that produces nigh-unlimited resources.
*** You don't even ''need'' this. You can just set up a manufacturing plant that just makes [[ZergRush tons and tons of gunships]]. Add in the above stationary guns, and you will obliterate ''everything.'' And these [[WeHaveReserves endless unit streams]] also are [[QualityVsQuantity hilariously effective]] against something humongous like UEF battleship or Cybran "Megalith" experimental. These things have huge amounts of damage per shot but slow rate of fire which leads to overkilling tier1 units without significantly reducing the horde's DPS.
** Units leave wrecks on their death so any player could reclaim them and thus get the mass depending on unit cost. This works like the wreck has health and WorkerUnit slowly reduces it while reclaiming and provides mass income in the process. You can guess what this means: one can just order to attack the land right under the already dead experimental which has tons of mass to destroy it and not let the enemy get resources if you can't get them too. Especially, firing a bunch of tactical missiles or T2 artillery is practiced. Also, the aforementioned nukes usually obliterate even these corpses.
* ''VideoGame/PaperChase'': How the dean destroys your documents. For the tuition receipt, he tears it into tiny pieces (and in the Inform version, also stamps on them), and for the transcript, he crumples it up and ''eats'' it.
* ''VideoGame/PlanetaryAnnihilation'' is likely SerialEscalation to the games above and below, allowing to not just NukeEm or FireArtillery, but actually use DeathStar, ColonyDrop, and DoomsdayDevice in an RTS game while nukes are expendable like tactical missiles in Supreme Commander and KillSat is a regular unit. You can [[TabletopGame/Warhammer40000 proclaim Exterminatus]] on the smallest of enemy bases just because his commander happened to be here. And there is also ridiculous amounts of units now without ArbitraryHeadcountLimit at all.
* Predecessor ''VideoGame/TotalAnnihilation'' has many of the same things, including across-the-map artillery and nuclear missiles. It also allowed for ''massive'' rushes that were never repeated until the sequel came out many years later.
** Its fantasy cousin ''VideoGame/TotalAnnihilationKingdoms'' allowed the player to build ''gods''. They took a ridiculous amount of time to build and the build process was a massive resource sink, but once built they could ''not'' be stopped. Their health was so high as to make them virtually invulnerable, and just ''one shot'' could destroy half an enemy base.
* ''VideoGame/WorldOfWarcraft'' has the Warrior class, whose Execute ability is typically the strongest single attack, and burns all of their Rage to make it ''more'' powerful - but can only be used on opponents under 20% HP. It's, [[ExactlyWhatItSaysOnTheTin well…]]
** Sadly, after a patch, Warriors can only burn 30 rage at a time. Good news is you can take talents to get a chance to use it outside the 20% HP mark.
** The Paladins have their own version, Hammer of Wrath. And fire-spec Mages passively deal more damage, all to targets under a fifth already.
** Drain Soul: Normally, it does some low damage and restores soul shards if it's up when a target dies. Use it when the target is under 25%, and whatever you're aiming at is going to drop fast.
** Soul Fire: Nothing says "die!" like a huge ball of fire that crits for 10k.
*** Shadow Bolt: Except maybe the screaming skull made of darkness that crits for 20k.
** However, despite the overkillness of those abilities — against bosses, who will still have a ton of health despite being at 20%… these can really win it for you in PlayerVersusEnvironment fights.
** Even ''Priests'' get one of these, with a twist. Shadow Word: Death is a finishing move that causes a huge amount of damage… but if you ''don't'' kill the enemy with it, [[DeathOrGloryAttack you take the damage as well]]. Since Priests are so squishy, the spell often ends up [[ExactlyWhatItSaysOnTheTin doing what it says on the tin]] either way. (Mostly, this is due to its instant cast and faster cooldown.)
** C'thun Green Beams. Imagine the standard chain lighting spell, except it doubles in damage each time it hits. If you screw up on starting the fight, the last person will be hit for several tens of millions; at the time the boss was released, that's many times your maximum health.
** Mimiron will launch some rockets from time to time. They are not hard to dodge and will do no damage outside a rather small area. Fail to dodge them, however, and you get hit for 5 MILLION damage. If at that stage of the game you have 1% of that, you can consider yourself a damn tough [[StoneWall Tank]].
** Monks have an ability called [[ExactlyWhatItSaysOnTheTin Touch of Death]] which is only usable on enemies with equal or less health than them and deals damage equal to the Monk's maximum health. A level 90 Monk Tank can have over a million hit points, a level one enemy has 55.

* Ike's Final Smash in ''VideoGame/SuperSmashBrosBrawl'' involves striking the enemy once, then catapulting them into the sky, where they are then slashed repeatedly with his sword before being hurtled back down to earth (and usually, [[ATwinkleInTheSky back off into the sky]]).
** Almost all Final Smashes are like this. Sonic and Pikachu start flying around dealing huge damage to whatever touches them. The Starfox fighters break through with their [[TankGoodness Landmasters]]. Mario shoots a [[WaveMotionGun ludicrously large fireball]] across the screen. Link does a combo of about two dozen hits before sending the enemy flying away. And that's just the tip of the iceberg. Some of these can, with the right timing, kill an enemy, and then kill them again as soon as they have respawned and their MercyInvincibility has expired.
*** In ''VideoGame/SuperSmashBrosUltimate'', it gets even crazier. This game allows you to use a new feature called "Final Smash meter", which functions the way any other fighting game's super meter would. Combine this with how crazy the Final Smashes can get, and matches with these get so flashy, they could outshine Las Vegas. However, it doesn't go too over-the-top — only one Final Smash can be used at a time.
*** Generally when you are K.O.ed in a ''Smash Bros.'' game that's the end of it. In ''VideoGame/SuperSmashBrosUltimate'', however, if an opponent gets Star K.O.ed with [[VideoGame/MetalGear Solid Snake]]'s Final Smash[[note]]Where he sends missiles after anyone he locks onto[[/note]], ''[[https://twitter.com/Electivirus/status/1072664715451609090 the missiles will still follow them into the background.]]''
** GuestFighter [[VideoGame/StreetFighter Ryu]] may just take the cake since he has options when it comes to his Final Smash: do you want to blast them over the horizon with a [[KamehameHadouken Shinkuu Hadouken]], or launch them into low orbit with a [[MegatonPunch Shin]] {{Shoryuken}}?
** GuestFighter VideoGame/{{Bayonetta}} is notable for having a Final Smash that provides a ''guaranteed'' kill (as opposed to merely an ''almost''-certain kill by sending the victim flying at absurd velocities): she summons the demon Gomorrah from Hell itself to devour her unfortunate enemies. They get a nasty bite if they're under 100% damage, but if they're over 100% damage, Gomorrah simply [[SwallowedWhole swallows them whole]] and returns to Hell with them for an instant non-standard KO. Oh, and in ''Ultimate'', Zelda, Ridley, Joker, and Sora all follow suit.
** On the subject of ''Ultimate'', the Adventure Mode "World of Light" introduces Galeem by it basically obliterating just about everyone with beams of concentrated light. Retaliatory force? [[TheJuggernaut Not even close to enough.]] Reflectors? [[ArmorPiercingAttack What's that?]] Divine shields? Kinetic force blows them aside. High-speed vehicles? [[AlwaysAccurateAttack Rocket locked on, you're next in my spree!]] SuperSpeed? [[IronicEcho You're too slow!]] Teleport aside? [[MoreDakka Quantity is a quality all its own.]] [[VideoGame/{{Splatoon}} Hide in the terrain?]] ''Fuck the terrain!'' Kirby only gets away by literally warping out of there, and even then the Warp Star had to put out literally all it had to pull ''that'' off; even one iota less power, and the story would be over before it even began.
* ''VideoGame/BrutalLegend'' has a move which summons a giant, flaming zeppelin that crashes into your enemies like a Hindenburg from Hell.
* Modern combat RTS ''VideoGame/ActOfWar: Direct Action'' has each faction equipped with a superweapon and counter-superweapon. International terrorist ring The Consortium's superweapon houses 3 shots per structure (and you can build multiple structures), making it alarmingly easy to simply inundate a base with superweapon attacks faster than the enemy can counter them. In addition, the Consortium superweapon is a satellite nudged out of orbit onto the target… but first, coated in e. bola. Needless to say, the strategy of "launching more satellites than you have Patriot missiles" tends to warrant some overcommitment of resources, just to be on the safe side.
* ''Franchise/{{Pokemon}}'': While not entirely the fault of the game itself, moreso that of the player, but there's nothing quite as satisfying as roasting a Lv. 2 Caterpie with a Lv. 100 Charizard with max Special Attack, using the strongest Fire-type attack in the game… and scoring a critical hit. It's even worse when you use Psychic with a Lv. 100, max-Special-Attack Mewtwo against a Lv. 2 Weedle… and still get a critical hit. This will often deal 65535 damage (the most any move can do in Gens I-III).
** KillItWithFire taken to the extreme: Given the structure of its evolution line, it's possible to produce a Level 1 Scizor (4x damage from Fire) specifically for link battles. You also get the same effect from breeding out a Level 1 Paras — which also has much lower defensive stats and has an ability which can increase its vulnerability to fire. Toasty!
** Take a Lv. 100 Heatran (highest Special Attack of all Fire-types bar Reshiram and Mega Evolutions), give it Choice Specs (boosts Special moves), boost its natural Special Attack all the way up, change the weather to sunny, activate Heatran's Flash Fire, and attack the above Paras with Overheat, the strongest Fire-type attack Heatran can learn. Put that through a damage calculator, and the damage reaches the millions — 6255207 damage. That would essentially erase that Paras from existence.
** For added fun, replace Paras with Scizor and have a Trevenant use Forest's Curse to add the Grass type to it beforehand, giving it a '''''8x''''' weakness to fire!
*** It gets better. As of ''[[VideoGame/PokemonRanger Pokémon Ranger: Guardian Signs]]'', Heatran can use the more powerful Eruption. Meaning that at full health under sun, with +6 Sp Atk and boosts from Flash Fire, Helping Hand, a Cherrim's Flower Gift, and a critical hit, with the target Paras at -6 Sp Def, Heatran can deal over ''10 million'' points of damage.
** The maximum possible amount of damage dealt in one turn by single Pokémon is believed to be this: A Shuckle with 614 attack stat from Power Trick, two Helping Hands, two Flower Gifts, skill-swapped Huge Power ability, at +6 Atk, with x2 boost from Metronome item, using Me First boosted Rollout after a Defence Curl, with Same-Type-Attack-Bonus, on a 4x Super-Effective Critical-Hit, against any Pokémon with a defense stat of 1 and 4x weakness to Rock. According to [[http://www.smogon.com/bw/articles/bw_complete_damage_formula this]] damage calculation formula, the damage dealt on the 5th turn (when Rollout and Metronome reach their maximum power) is 721,898,952. Over seven hundred million. One imagines that if a Pokémon were to be hit with an attack of this magnitude, rather than merely fainting, both the target Pokémon and everything else in a large radius would be reduced to nothing more than an expanding cloud of ash and a smoking crater. As they say, "You don't fuckle with Shuckle."
*** To give you an idea of how ridiculously overkill this all is, the highest amount of HitPoints a Pokémon can have is '''1428''', and even in that particular case, it's only for three turns.[[note]] Which is a Dynamaxed Blissey with 31 HP [=IVs=] and maximum EV investment in HP.[[/note]]
** With the help of stat-increasing attacks and an accessory that doubles Attack, it's possible in some versions to get the Attack of a Marowak so high that it actually wraps around and becomes extremely low, thanks to a bug. That the bug is fixed in later versions only causes Marowak to become the EPITOME of overkill (1000+ Attack)... [[GlassCannon if it can survive long enough]].
** In a strange non-damaging example of this trope, there are early-game trainers of the Rich Boy and Lady trainer classes in ''VideoGame/PokemonRubyAndSapphire'' and ''Pokémon Emerald''. They use [[ComMons Zigzagoon]] at level 7. The overkill is that, instead of using common cheap healing items like a normal Trainer would do to heal their Pokémon, they use the late-game Full Restores to do the job. For comparison: A potion costs 300, heals 20 HP, and is readily available in any store. Full Restores cost 3000, restore all HP as well as remove any status problems, and are only available super late game. Keep in mind they're using them on ComMons that are probably lower level than your starter by that point. Pretty over[[IncrediblyLamePun heal]], isn't it?
** In theory, the most damage that a Pokémon could do would be 202,786,432,200. Conditions do not yet exist to create this scenario, but a 255 base Attack Fire-type with Huge Power as an ability with +6 Attack, while running the maximum amount of [=EVs=], [=IV=]s, and Nature boosts could use a Fire-type version of Rollout after using Defense Curl and after maximizing out its held Metronome item, while two Cherrim are partnered to it in sunlight could get a critical hit against a Pokémon with base 1 Defense that has its Defense lowered to -6 and has no [=EVs=], [=IV=]s, and has a Nature decrease to Defense when the Pokémon is Bug/Steel with Dry Skin as an ability and has been hit by Forest's Curse. If the move hits for maximum damage, it would be 202,786,432,200. That's over TWO HUNDRED BILLION. And at Level 1, depending on its base HP and its [=EVs=] and [=IV=]s, the defending Pokémon will only have 11 to 17 HP to lose. Yeah.
** One example that actually happens in-game comes in ''VideoGame/PokemonSunAndMoon''. An [=NPC=] mentions that Trial Captain Lana once used her signature Z-Move Hydro Vortex to get a Sudowoodo to move. Assuming that her Araquanid was the one using the move (which it is if you fight her), Hydro Vortex is based on Bubble Beam, meaning it has a base power of 120. Since this is super-effective on Sudowoodo, that goes up to 240 base power. And that's without STAB; with it, the move would reach 360 base power. 120 is a very high power for a move. 240 is ''terrifying''. 360 is "[[ThisIsGonnaSuck welp, I'm screwed]]" levels. And that's ''Bubble Beam''; a Hydro Vortex based on something like Surf or Hydro Pump can hit ''even harder''. The Sudowoodo in question [[ScrewThisImOuttaHere runs away in terror]] when it realises that the player can now use Hydro Vortex, and you can't really blame it.
** In terms of moves, Dracovish's Fishious Rend can be one of these. The move's base power if the user moves first is 170 (original base power of 85 that doubles if the user ges first). Factoring in STAB, a Choice Band, Strong Jaw, rain, and double weakness against Water (170 x 1.5 x 1.5 x 1.5 x 1.5 x 4), the move's total power comes out to '''''3442.''''' For comparison, a super-effective STAB Z-Move based on a 140+ power move comes out to 1200 base power, and the highest power Max Moves are 150 base power. Anything hit under optimal conditions with Fishious Rend would be snapped like a twig under Dracovish's jaws.
* The ''VideoGame/{{Worms}}'' series. Your enemy is down to the last worm, and standing on a ledge just begging to be [[CherryTapping poked?]] Nah… still got that HolyHandGrenade!
** Especially when you make custom settings with explosions turned all the way up, and even more so with a third party program like ''Worms Armageddon'''s Fiddler which lets you monkey with just about every setting in the game. Letting loose with a high-explosive [[GatlingGood minigun]] is very satisfying.
** By exploiting a bug related to the quick switching of weapons, it was possible to fire a minigun but use ''bazooka rockets'' as ammo. The typical result was, of course, blasting a tunnel through the whole map and killing everything in the way.
* The ''VideoGame/DinosaurKing'' game features many attacks that very much appear to be overkill. One such attack involves knocking the opponent over and then literally ''stomping them into the ground.'' As that attack only gets that effect at a certain level of HP, it can be very satisfying if you've been beaten a lot over the course of the match. Others involve the opponent being set on fire, stomped flat, falling head-first from great heights, drowned, crushed by giant falling rocks, and being ''impaled on lightning.''
* The Final Strike from ''VideoGame/MegaManXCommandMission'' is designed for this. If you do enough damage to an enemy to reduce their current HP down to 25% or less of what they had previously with a non-subweapon attack without killing them, you can use the Final Strike which allows the player's party to initiate a barrage of shots and blows supposed to deal total damage way in excess of what is necessary, rewarding players for doing so with bonuses afterward. You can also do this to more than 1 enemy at the same time if you manage to hit several weakened enemies with a multitarget attack at the same time, and doing so increases the amount of time you can keep pounding away at them: this is also necessary to unlock some of the better [[ItemCrafting FMEs]] for the FME Generator. Of course, against some bosses, 25% health is still a few % too many.
* When Mega Man finalizes and performs the Red Gaia Eraser in ''VideoGame/MegaManStarforce 3 Red Joker'', he first fires off a laser of noise, which is more than enough to kill a weak boss, then the plates on his shoulders detach to perform a sweep beam, and it ends with a gigantic, field covering explosion. Nothing that isn't a major boss at full health should be left standing after this. In Black Ace, the Black End Galaxy involves throwing a ''black hole'' at the enemy and then slicing them in half.
* In ''VideoGame/MegaManStarForce 2'', The Tribe King's LFB on a one hp Mettana.
* In ''VideoGame/{{Painkiller}}'', a great many of the weapons not only kill the enemies but sends their limbs flying off in every direction in a shower of blood. Bonus points when done to a whole pack of enemies at once and double bonus points when done in slow-motion, and extra gold for juggling a enemies' dead body.
* ''VideoGame/NoMoreHeroes'':
** After hitting a {{mook}} enough times, Travis can perform a special move that decapitates the {{mook}}, showering Travis in blood and coins. This becomes practical later in the game — said special move can also decapitate/split in half other mooks nearby, resulting in multiple showers of blood and coins.
** Once he's been knocked down to half health, [[spoiler:Henry]] gains an unbelievably awesome OneHitKill move. He ''impales'' Travis, flings him off the beam katana into the sky, at a 45-degree angle, jumps into the air and knocks him straight upwards after he's already a good forty feet up, and when he's high in the sky, leaps up once more, grabs him, hurls him downwards with a bodyslam, and finishes it by descending, standing on his beam katana, to impale Travis ''again'', so hard it sends chunks of pavement flying.
* ''VideoGame/NoMoreHeroes2DesperateStruggle'': Shinobu likes to [[OffWithHisHead cut off heads]] and then ''cut the heads into pieces''. [[spoiler: Given what Destroyman came back from, it might not actually be that unreasonable.]]
* Surprisingly, ''VideoGame/ArmoredCore'' offers you a SadisticChoice (at least in the early games) in terms of overkilling. If you shoot an enemy enough, it will burst into flames. Rest assured, it will die soon. However, until it actually [[NoBodyLeftBehind explodes into nothingness]], it can, and ''will'', keep firing. Do you [[DeaderThanDead overkill]] it (which does speed up its death), wasting your ammo in the process (extremely important in some long missions without ammo boosts), or do you leave yourself vulnerable to its last attacks? Most players TakeAThirdOption, either by using a laserblade (which costs no ammo), or running away real fast.
* The Novalith Cannon in ''VideoGame/SinsOfASolarEmpire''. Smaller worlds die from one shot, and the only way to survive two is to use the TEC-only Planetary Shield. The kicker? There's no possible way to stop a Novalith shell once fired ''even if you manage to conquer the target world and colonize it before your shells hit''.
* ''VideoGame/MasterOfOrion II'' has a device that [[EarthShatteringKaboom blows planets apart]], ''a la'' the [[StarWars Death Star]]. For when you absolutely, positively have to kill every last living thing bigger than a microbe.
* ''VideoGame/{{Mercenaries}}'':
** The series offers the choice of overkill, especially once more powerful airstrikes become unlocked. Sure, you could just run up to the target, shoot him, and then verify him, but it's much more fun to watch the entire city block he's hiding in get blasted to hell by a carpet bombing run.
** In ''Mercenaries 2'', you get the option to purchase a tactical nuke and use it against anything and everything.
** It is mentioned that Mattias Nilsson, one of the playable characters, loves this trope, preferring to eliminate targets that would normally only require small arms fire with air strikes.
* Overkill abounds in the RTS ''VideoGame/RiseOfLegends''. The secondary combat unit of the Vinci faction is a 15-foot clockwork robot that is equipped with a lightning gun, while their most powerful unit is something akin to a weapons factory with legs the size of tower cranes. The magic-wielding Alin have access to 50-foot golems built entirely out of glass, as well as crystalline spiders the size of tanks. Both smush enemies with little discrimination. The spacefaring Couatl frequently utilize some very large laser beams in combination with giant stone mechs.
* In ''VideoGame/DragonBallZBudokai 3'', battles in the story mode and arena mode net you more experience points for finishing a fight dramatically. A signature energy blast move is good. A 30+ hit rush (possibly capped with a signature energy blast) is even better. A signature super move visible from space — which the game will never neglect to show you — is best of all. But being a ''Franchise/DragonBall'' game, if you're not finishing fights like this anyway, you're not playing it right. For added effect, using an energy blast to finish things off will crack your opponent's HUD, while the super move will cause the thing to explode.
** It should also be noted that most of these super moves visible from space will actually completely destroy the terrain as well, turning places like Namek into an equivalent of the Underworld, complete with lava and desolation for miles.
* In ''VideoGame/QuakeII'', a downed enemy can be gibbed with enough firepower unloaded into his body, which may be advisable as sometimes a seemingly dead enemy will fire off some last shots at you.
** ''Quake Live'' has an achievement for finishing off someone with 1 HP left with the Rail Gun, the most damaging weapon in the game.

* In ''VideoGame/MetalGearSolid'', in your fight with Vulcan Raven, he uses a gatling gun that ''he took from an F-16'' to shoot you with, while the most effective weapon to use against him is a Stinger missile launcher.
** In one of the joke scenes from ''VideoGame/{{Metal Gear Solid 3|SnakeEater}}'', The Boss uses the Davy Crockett nuclear missile launcher against Snake. ''At point-blank range.''
** In ''VideoGame/MetalGearRisingRevengeance'', it is entirely possible to use Blade Mode to cut someone/thing into over a hundred little bits.
* ''VideoGame/JakAndDaxter'' didn't qualify until ''VideoGame/JakIIRenegade'', in which Jak got a SuperpoweredEvilSide possessing ''two'' kill-everything-on-the-screen attacks, as well as flickers of [[RuleOfCool cool]] purple lightning that followed his attacks. Then he got a gun capable of firing a lightning orb that blows up every hovercar on the screen. Then ''VideoGame/Jak3Wastelander'' handed him an ''upgrade'' to this gun which burns through at least half of your ammo in one shot… a shot which is so large ''it gets its own mushroom cloud''. As well as a variant form of his yellow gun which fires an AttackDrone that [[MoreDakka spams out ammo so fast it resembles a small but deadly rainstorm]]. Someone's really got to explain the concept of 'less than total destruction' to him. Ditto with [[AristocratsAreEvil Baron Praxis]], who intends to stop the Metal Heads with [[spoiler:''a bomb that can blow up the universe! All of it! That's less like "overkill" and more like "omnikill"!'']]
* ''Franchise/RatchetAndClank'' often have guns which veer [[{{BFG}} encouragingly close]] to being overkill. Starting with the [[FunWithAcronyms R.Y.N.O.]] and moving up to its ''[[VideoGame/RatchetDeadlocked Deadlocked]]'' equivalent, which ''rains laser beams from orbit''. And then there's Clank's HumongousMecha form, which in the [[VideoGame/RatchetAndClankGoingCommando second game]], is entirely capable of ''razing every building on a [[SciFiWritersHaveNoSenseOfScale small]] but heavily urbanised moon.'' You get a ''[[RewardingVandalism Skill Point]]'' for that, too.
** Arguably, it started with the Visibomb gun, a weapon that shoots a remote-controlled missile. On the right stages, you can stand at the beginning of a stage and shoot enemies clear on the other side of it.
** The [[VideoGame/RatchetAndClankUpYourArsenal third game]] has the [=RY3NO=]. Fully upgrading this give you the RYNOCIRATOR, which ''burns every on-screen enemy into ash''.
** The RYNO IV (from ''[[VideoGame/RatchetAndClankFutureToolsOfDestruction Tools of Destruction]]'') was banned in 59 galaxies, including the one that you're currently in, and the mere act of ''talking'' about it is grounds for being thrown into [[TheAlcatraz Zordoom Prison]] indefinitely. The original holoplan was torn into 12 pieces and thrown across the galaxy, so nothing like it could be built ever again (as [[MegaCorp Gadgetron]] thought it was too dangerous, and we're talking about a company that sells ''portable black hole launchers.'' To quote: "point away from face").
** Obviously they didn't do a good enough job of discouraging the inventor, since ''[[VideoGame/RatchetAndClankFutureACrackInTime A Crack In Time]]'' brought us the RYNO V. This was unanimously voted the weapon "Most Likely To End All Life As We Know It", outlawed ''everywhere,'' and, again, the plans were torn apart and scattered to the winds. The RYNO V is notable for having an inbuilt speaker system that plays [[StandardSnippet the 1812 Overture]] whenever you fire it. Because, you know, when you've got that much firepower, why the hell not?
** And then, somehow, the Plumber got his hands on some RYNO V plans, because by the time of Into the Nexus, he has created the RYNO VII, which is like the RYNO V, but with more missiles and bullets, a sleek purple and black trim, and the added bonus of playing Night on Bald Mountain, the perennial music of complete '''doom'''.
* In ''VideoGame/{{Postal}} 2'', after killing or crippling people, you can choose to do some of the most sadistic things to them, such as chopping them to pieces with a machete, setting them on fire, smashing their heads with a sledgehammer, blow them to pieces with a rocket launcher, break every bone in their body with a blunt object, etc.
* In ''VideoGame/NeverwinterNights'', it's common for casters to open locked and trapped boxes with ''[[KillItWithFire Fireball]]'' spells. This is an incantation designed to ''clear rooms''.
** Incredibly annoying because of a ScrappyMechanic that forces you to whale on a chest with your weapon coupled with chests that resist damage that would drop an ogre. Apparently, either locks must be picked or the chest utterly destroyed, because no one can carefully use a [[FridgeLogic hatchet and prybar]] to open something.
** This is also the game that, with the gore settings all the way up, things explode in a shower of blood and bones when you kill them with a critical hit. This also works when killed by Instant Death spells — Implosion and Destruction actually look like they are ripping people inside out when they go off. Implosion is Area of Effect, so if it hits a few creatures, the result is usually a fountain of blood and bones.
* Thanks to her AI being set to "overkill" by default, Qara of ''VideoGame/NeverwinterNights2'' has been known to cast [[DeathFromAbove Meteor]] [[KillItWithFire Swarm]] or [[HerdHittingAttack Burst of]] [[KillItWithIce Glacial Wrath]] on one little orc. Annoyingly, this usually destroys nearby loot chests and/or kills ''you'', if you happen to be in the immediate vicinity.
** In the original campaign, [[spoiler:Shandra]] is [[ImpaledWithExtremePrejudice impaled on an ice spike]] and set on fire before being [[LudicrousGibs blown apart]] by an Eldritch Blast. Note that this happens ''after'' [[spoiler:she's]] already been sliced open and has lost a good pint of blood.
** The expansion can let you ''completely obliterate someone from existence'' by ripping their soul out and eating it, which is completely different from the regular soul-eating ability in that whoever loses their soul this way can ''never'' be reborn. This is an ability you literally get in the last five minutes if you're ''really'' evil, and you only get to use it on three people: [[spoiler:your former companions]]. Just as well, since [[GameBreaker it's incredibly hard to dodge and doesn't allow saving rolls to be made if it hits]], which would make any campaign ridiculously easy.
* In ''[[VideoGame/TronTwoPointOh TRON 2.0]]'', there is a subroutine (weapon) called the [[spoiler:Prankster Bit]]. Not only is it a 1-hit KO (sometimes killing the player if they stand too close to the blast), but it can even get you a NonstandardGameOver if an NPC is sucked in ([[spoiler:it acts like the ''Film/{{Tron}}'' equivalent of a ''black hole gun'']]). Overkill in a situation versus one or two enemies ([[spoiler:especially if they are Intrusion Countermeasure Programs, where a Disc Primitive will work, and can even block the opponents' Discs]]), but great when trying to kill multiple enemies at once. Also the best weapon in the final boss battle, against [[spoiler:the corrupted fCon Team, where you have to derez them one part at a time. The Prankster Bit can take about 10% off their life bar per hit (again, watch that blast radius), but it drains a heck of a lot of your energy. A high Weapon Efficiency rating is recommended. The Cluster Disc works almost as well, at a fraction of the energy.]]
* In the HopelessBossFight at the beginning of ''VideoGame/PaperMario'', Bowser whittles Mario down to almost no HP… then hits him with an attack that does ''10'' damage, which is pretty high-powered for this game.
** That's your entire health meter at that point in the game. At the end of the game, your health bar maxes out at 65, using every badge you can find to do it.
** Once Goombario is Level 2, he can use Charge. The player can have Goombario keep charging his power (provided Mario doesn't run out of health) until it is extremely high and overkill an enemy with Headbonk. The overkill can be even greater when Goombario is level 3 and can use Multibonk. This, incidentally, is especially useful against [[ThatOneBoss Huff N. Puff]], if Mario is protected by Stone Caps.
** In ''VideoGame/SuperMarioRPG'', a properly-used Geno Whirl will always do 9999 damage. The enemy with the highest health in the game has roughly 2000 hit points less than this (however, with the exception of Exor it can't be used on bosses).
* The hip-hop-themed fighting game ''[[VideoGame/DefJamSeries Def Jam: Fight For NY]]'' actually ''required'' you use stronger means than a normal punch to finish your opponent and end the match, usually in the form of high-powered combos, ''smashing your opponent into an element of the stage'', hitting them with a weapon, or the oft over-the-top special moves. And that's not counting the stage where you can push them in front of a passing subway train…

* In ''VideoGame/BaldursGate'', a party member being reduced to enough hit points below zero prevents them from being resurrected, presumably because they've been pulverized. It's also possible to turn someone to stone or freeze them into an ice statue, then shatter it. For extra fun, petrify someone, then turn them back to flesh, then OneHitKill them. Oh, and if the Gore setting is on, when enemies take enough damage they explode into chunks of meat.

* ''VideoGame/EternalDarkness'' features a ''double-barreled elephant gun''. Firing it without bracing yourself first will knock you on your ass. And yet it is not the most damaging weapon available even in that level, nor is one shot from it sufficient to kill most foes.
* ''Franchise/ResidentEvil''
** In ''VideoGame/ResidentEvil3Nemesis'', how does the titular Nemesis show the audience that [[ItCanThink He Can Think]] ''and'' that he's not one to be messed with? Rather than simply smash through the front door of the police station to chase Jill, the already practically unstoppable killing machine decides it would be better to go and arm himself. ''With a missile launcher''.
** ''VideoGame/ResidentEvil5'''s ultimate unlockable shotgun Hydra has ''three'' barrels side-by-side. Sheva has to wield it two-handed, but Chris and Wesker are so ridiculously ripped that they simply widen their stance and fire it with one hand at arms length. It has enough knockback potential to put any standard foe on its ass and does damage on par with a standard rifle at long-range, despite being… y'know… a {{sho|rtRangeShotgun}}tgun.
** How [[spoiler:Albert Wesker]] is killed at the end of ''VideoGame/ResidentEvil5''. Hit by ''two'' rockets, which explode him into a lake of molten lava. Justified, because his mutations make him immune to most conventional weapons at this point.
* ''VideoGame/MaxPayne''

* ''VideoGame/AceCombat6FiresOfLiberation'' requires you to fly your plane down the barrel of the Chandelier cruise missile launcher. Yes, a launcher with missiles so big you can fly a plane down its barrel. If a missile is launched with the plane still inside, well, "OneHitKill" is putting it… lightly. On the player's side, it's easy to single out a single target for all four or six special missiles, pop off the heaters and lose a few gun rounds as well. Or feed a single, isolated ground target a FAEB/LSWM/MPBM, all weapons meant for wide-area devastation.
** ''VideoGame/{{Ace Combat 5|TheUnsungWar}}'' also has this with the Falken's Tactical Laser System, and ''[[VideoGame/AceCombatZeroTheBelkanWar Zero]]'' has the one on the Morgan.
** ''VideoGame/AceCombatInfinity'' includes an "Overkill" score bonus for killing enemies in this manner (e.g. hitting an enemy ready to die from [[CherryTapping a single cannon round]] with a pair of missiles, or hitting someone with a missile after a teammate's killed him).
* ''VideoGame/AirForceDelta Strike'' pits the player against the Leupold battery of gigantic rail-guns, so large you have to fly down the barrel. The barrel is actually ''five'' separate railgun barrels built as one. You have to maneuver your plane between shells, depending on which barrel is about to fire next. The enemy has ''three'' such railguns that you have to take on in that mission.
* ''[[VideoGame/SoulSeries Soul Calibur 4]]'''s [[https://www.youtube.com/watch?v=UcMY-sgZEc4 Critical Finish]]. Also the fact that in Arcade Mode, you get extra points for hitting the downed corpse of your enemy when you win a round.

* The VideoGame/{{Touhou}} fangame ''Touhou Soccer'' is basically Soccer played with additional rules that permits the use of spellcards or youkai powers on the ball. This results in [[RuleOfCool excessively spectacular]], [[VideoGame/SuperRobotWars SRW-style]] danmaku barrages on the unfortunate ball. For example:
** [[BattleButler Youmu]] [[DefaceOfTheMoon carves her sword technique's name on the moon]] [[AbsurdlySharpBlade before cleaving it with her swords]] and uses the momentum to launch the ball at extreme speeds.
** The [[OurVampiresAreDifferent Scarlet Sisters]] use their weapons, ''Laevatinn'' and ''Gungnir'', in addition to their danmaku techniques, for their combination attack.
** Yuuka, Marisa, and Mima all ''nuke'' the ball with several permutations of the [[{{Kamehamehadoken}} Master]] [[WaveMotionGun Spark]].
*** Marisa in particular has a combination technique, where Alice and Patchouli cast buffs on her before she does a ''very'' good impression of Thrugelmir's ''Blade that Cleaves Continents'' that even '''shreds''' the spectator stands. Thankfully for the audience, spellcards only inflict all non-lethal damage…
** Mokou and Flandre [[SpamAttack have techniques where they kick the ball thousands of times]] before it can escape.
*** [[{{Shinigami}} Komachi]] also goes wild on the poor ball with her SinisterScythe.
** Inverted in Cirno and Letty's combination strike. [[TheDitz Cirno]] moves to blast the ball with her [[AwesomeButImpractical Icicle Fall (Easy)]] spellcard, apparently forgetting that it can't hit anything directly in front of her… like, say, an oncoming soccer ball. The ball proceeds to hit her in the face — not once, but ''fifty bajillion times'', making it a rare case of overkill from the target to the attacker. Though to be fair, it's still a good hit and the ball can rebound and score a goal.
*** Also, Rinnosuke's ([[MemeticMutation MANnosuke!]] NICE COMBINATION with Tokiko. He kicks the ball hard, into the poor youkai's face, then it rebounds into the goal. It's one of the strongest moves in the game.
** And then there is [[https://www.youtube.com/watch?v=kofnEdB8Blc this from Mima]] just a little bit stronger than the above move enough that is the most powerful single shot in the game. Yes, it is entirely necessary to [[DeathFromAbove orbitally bombard]] a hemisphere to hit a soccer ball.
** Hilariously inverted with [[https://www.youtube.com/watch?v=R4omz3nrUw4 this]] one by Hong Meiling.
** [[https://www.youtube.com/watch?v=u9Qa9AIxJhs All you need to know about Touhou Soccer.]]
** [[https://www.youtube.com/watch?v=vlBWNGq72DY& "Shikieiki's Final Judgement"]] puts even [[Franchise/LyricalNanoha Nanoha]] to shame. The highest-rated comment on that video happens to be the caption for the BeamSpam page image.
* ''VideoGame/CrossEdge'' allows you to beat enemies beyond death with high-damage combination attacks in order to get hard-to-find items useful for ItemCrafting.
** ''VideoGame/AgarestSenki'' is based on a variation of ''Cross Edge'''s system, and also allows overkills. Normal item drops are random in Aragest, but an overkill guarantees an item.
*** Both games also feature a break system (''VideoGame/CrossEdge'' has three!) which allows you to destroy an enemy's defenses, increasing damage for all remaining attacks in the chain.
*** Both get topped by ''Agarest Senki 2'' [[https://www.youtube.com/watch?v=OXJq7akpeYc where they unleash]] an Ultimate Strike, ''and a [[FinishingMove Finish Strike!]]''
* On the [=PS3=]/360 versions of ''VideoGame/SonicUnleashed'', the Nightmares (the regular, almost lizard-like enemies) have a dying animation which takes a few seconds. It begins with the Nightmare standing, then it slowly collapses until it dies. However, if the enemy gets hit at any time in this animation, it resets. You can make Sonic the Werehog do quite the overkill, especially when all your stats are fully levelled up, and you just whale on an enemy long after it's dead, working up a huge combo, then giving it an uppercut and smashing the enemy into the ground full force. It's up to you whether this example combines with VideoGameCrueltyPotential.
** The bottomless pits; just smash the hapless enemies off the edges and watch them fall and die.
** Smooshing enemies into pancakes with your hands. It's especially fun when you get into the higher-level combos. One-two punch, followed by smashing it between your two giant fists, followed by a powerful spinning backhand, followed by grabbing their ankles and slamming them into walls and the ground repeatedly....
* In ''VideoGame/{{Prototype}}'', it's possible, as shown even in the early trailers, to grab someone, jump on a high building (the Empire State Building, for instance), then jump, grab the person you were holding, crash it to the ground, grab it again, jump, crash into another floor, grab, crash, grab, and all the way to the street-level.
** Not to mention other horrible things you can do. Punching through 5 people at once? No problem. Grabbing a helicopter with a whip, hijack it and use it as a landmower (where grass = people on the sidewalk) or simply jump in the air, land on someone, use his body as a skateboard and kick his corpse into a wall or a car, splatting it into tiny pieces. Or just jumping at the center of a crowded street and kill everyone with a burst of tentacles or spikes coming from beneath the ground.
*** Let's just say this entire game is based around overkill. Even the military needs to use overkill just to put a dent in Alex.
* If you keep on attacking your opponent even after they are long gone, ''VideoGame/BlazBlue'' will actually award you a trophy for it: "It's The Only Way To Be Sure."
** If you turn "show damage" on and perform an Astral Heat in training mode, you'll see that an Astral Finish can do up to 20,000 damage. The highest HP character in the game[[note]]except Unlimited Ragna[[/note]] has 13,000 health (Tager), and will likely have only 2,000 left before you can initiate an Astral Heat.
** Ragna, with his Astral Heat, slices the opponent with his SinisterScythe, then transforms into... something... and then erases the target from reality. Really.
** With Haku-men's Astral Heat, Akumetsu, the screen is so filled with [[GoryDiscretionShot blood]] that it turns black for a second.
** If punching a sucker in the face so hard it leaves a fist imprint in the soon-to-be-shattered moon doesn't qualify as overkill, then Makoto's Astral Heat (Planet Crusher) is doing something wrong.
** The final boss of the first game, [[RobotGirl Nu]]-[[YouAreNumberSix 13]], summons a {{BFS}} a few hundred feet long and a dozen or so feet wide with her Astral and proceeds to stab the opponent in the face with said sword (seen from her victim's pov, none the less). The final boss of the sequel, [[PersonOfMassDestruction Mu]]-[[CloningBlues 12]], has a reworked Astral in the third game with which she summons ''eight'' such swords to stab the opponent with. [[StuffBlowingUp And then]] [[MadeOfExplodium the swords explode]].
** A story example occurs in ''Chronophantasma''. [[spoiler:One fight in Chapter 12 has Arakune on the business end of a CurbStompBattle by [[ColonelBadass Kagura "the Black friggin' Knight" Mutsuki]], but if that wasn't enough, not only is [[PowerNullifier Celica scrambling the seithr that comprises Arakune's "body" by proximity]], but [[PersonOfMassDestruction Ragna the Bloodedge]] and [[{{Determinator}} Makoto Nanaya]] were on hand in case Kagura had any trouble. All of this because he tried to [[ImAHumanitarian eat Noel]]. Running like a bitch was probably for the best.]]
%%* ''VideoGame/GodOfWarII'', specifically Theseus' death.
* ''VideoGame/RagnarokOnline'' has a job build for Monk, which uses all of your SP for a single attack, also preventing SP regen for a few minutes afterwards. These builds usually result in someone dying, as monks are rather squishy. This build is the main reason Monks have their reputation as boss killers.
* ''VideoGame/{{Doom}}'' was probably the first game ever to make overkill somewhat worthwhile, by introducing us to LudicrousGibs. There's also the ''VideoGame/RussianOverkill'' weapons [[GameMod mod]], which includes, among other weapons, tank cannons, handheld {{Macross Missile Massacre}}s, and nukes. Even the [[ElementalPunch Falcon Punch]] attack alone may burn (literally) through tens of enemies at once. It's utter madness.
* ''VideoGame/RiseOfTheTriad'', an Apogee game that was released around the same time ''VideoGame/{{Doom}}'' was, included several weapons with ridiculous amounts of explosive firepower such as the napalm-laden Firebomb, the six-missile-overkill Drunk Missile, and the Dark Staff. Any one of these weapons could be found on the first level. Not only would the enemy be gibbed upon contact, but any surrounding enemies caught in the blast would also be wiped out, and in extreme cases, [[CoconutEffect gibs would stream down the screen]], with an accompanying message "Ludicrous Gibs!" displayed at the top-left corner. Needless to say, these were long-distance weapons, and any player too close would be [[RocketJump thrown into the air]] and most likely be killed in the blast.
* Singularity Planet Busters from ''VideoGame/SidMeiersAlphaCentauri''. For when you really need to turn the heartland of an opposing faction into a vast water-filled crater.

* ''VideoGame/EmpireEarth'' includes an epic version of the age progression present in the ''VideoGame/AgeOfEmpires'' series. Once you get your first level of rifle infantry they are utterly devastating compared to the previous tiers of footmen, but of course, military superiority altogether can be taken to absurd levels depending on how fast you can rise through the eras relative to your opponent. Are you nuking individual cavemen?
* With the ability to summon ''anything'', ''VideoGame/{{Scribblenauts}}'' is rife with opportunities for this. Park full of trash? Use a black hole. Bee attacking you? Time for a [[GatlingGood minigun]]. Defeat a barracuda with [[EldritchAbomination Cthulhu]]! Summon God as your personal bodyguard! And so on...
* ''VideoGame/EVEOnline'': Records show that the top usage of Titan Doomsday Devices for December 09 was the destruction of Battleships. A Titan DoomsdayDevice does up to 3 MILLION HP of damage and never misses. The theoretical maximum HP of battleship (factoring resistance to damage) remains under 600 thousand HP.
* ''VideoGame/{{Homeworld}}'''s capital ships were heavily armored. The concentrated fire used to kill them off quickly commonly involved 10-50 capital ships, each firing 1-4 enormous ion cannons ''at the same target''. The last few missions of the original game could involve hundreds of ships concentrating fire on a single target.
** The Taiidan Emperor in the campaign loves it, but can't always pull it off. The first time happens during a cutscene, when the planet of the Kushan is hit with weapons that ''burned its atmosphere off'', just for a violation of a treaty so ancient that the Kushan didn't even remember it existed. Then in mission 15, the Taiidan attack the Mothership by throwing a gigantic asteroid at it and escorting it with one of the most massive fleets they ever fielded. The kicker? The asteroid was just a distraction to assemble an overkill fleet for the final battle.
* In the last mission of ''VideoGame/FreeSpace2'', the genocidal Shivans [[spoiler:invade and destroy an entire star system]] in what can only come across as a literally astronomical dick move, given their enigmatic motives.
* In ''VideoGame/{{Sacrifice}}'', nearly all of the most powerful spells fall under this trope. In particular, the spell that summons a volcano or the one that causes a giant circle of ground to fall away. The spell that vaporizes a target unit's intestines for a one-hit-kill & gib may also qualify. A similar spell achieves the gib by dropping a giant cow on the target from several hundred feet in the air.
* In ''VideoGame/TheWorldEndsWithYou'', the power of a [[CombinationAttack Fusion]] is determined by three multipliers: Attack score, the Difficulty setting, and a power score unique to each fusion. [[JackOfAllStats Shiki's]] strongest fusion has a multiplier of 20 (10 more than her 2nd level). [[GlassCannon Beat's]] third level fusion has a multiplier of 30. And Joshua's third level fusion has a multiplier of ''99.99''. Fitting, since it ''does'' "[[ColonyDrop drop the freakin' moon]]".
** Minamimoto's ultimate technique: Level ''i'' Flare. A bit of explanation: In Square Enix games, a spell designated "Level whatever Spell" can hit all targets with a level that can be divided by the spell's (so a Level 4 Flare can hit targets with a level of 4, 8, 12, etc. and a Level 1 Flare can hit anything). For those who aren't math geeks, this means that the Level ''i''[[note]]i being the square root of negative 1][[/note]] Flare hits ''anything and everything'', including imaginary and/or complex targets. Overkill indeed.
* The M-920 Cain heavy weapon in ''VideoGame/MassEffect2''. Its nickname is the "Nuke Launcher," though technically, it's only firing a small piece of metal at relativistic speeds. Either way, it causes a big boom. Using it against the toughest bosses practically kills them outright. In the third game, it is used to take out a Hades Cannon (A reaper sized Anti Aircraft gun) in one shot, demonstrating it's raw power. Using it against weaker enemies is the very definition of overkill. There's also the downloadable M-490 Blackstorm Projector, which basically creates a miniature black hole that draws in nearby enemies until it collapses explosively.
** The sheer amount of resources that the [[EldritchAbomination Reapers]] have poured into neutralizing Commander Shepard is simply awe-inspiring. Given that s/he's [[DidYouJustPunchOutCthulhu killed a few of them,]] it's a bit justified. Hell, Harbinger's ''first shot'' in ''2'' was to have your entire ship blasted into scrap metal.
*** Taken even further at the final confrontation in ''Mass Effect 3''. When Shepard leads a charge on foot on the teleporter that will take him/her to TheVeryDefinitelyFinalDungeon, Harbinger tries to shoot Shepard personally with its massive ship-killing WaveMotionGun to prevent that from happening. [[spoiler:It even hits, but still isn't enough to completely kill Shepard, [[{{Determinator}} who continues to crawl and limp the final meters]]]]. To put another way: a two-kilometer tall dreadnought specifically designed to fight entire fleets singlehandedly descends from orbit for the sole purpose of stopping ''one on foot soldier'' from entering a teleporter.
** The Widow Sniper Rifle, which is designed to pierce tank armor. If you use it in ''VideoGame/MassEffect2'', you'll primarily be using it against infantry.
** The plan to destroy the Reaper on [[spoiler:Rannoch]] was to get around its jammers by having Shepard get a visual target lock on the ground to let the Normandy hit it in a fast low-altitude flyby. When that didn't cause it any significant damage, EDI linked the entire [[spoiler:Quarian]] fleet in orbit to the targeting signal. (And even that just barely managed to kill it.)
** The Citadel DLC has a cutscene where Shepard covers the squad as they climb a ladder. Afterwards, Shepard is cornered by a grand total of about 4 enemies. Everyone (about 10 elite troops) leans over the balcony and unloads 200 rounds into them and the ground around them.
--->'''Wrex:''' That's why I love hanging out with you guys! Why shoot something ONCE when you can do it 46 more times!\\
'''Javik:''' I find what primitives lack in aim, they make up for in ammunition.\\
'''Liara:''' I dunno… are you SURE you got them all?\\
'''Garrus:''' And that's the moment when the universe ran out of ammunition!
** This is also how [[MultipleChoicePast Colonist Shepard's]] parents were killed. They tried to fight back, so the batarians hit them with an artillery strike.
** Two of your primary sniper teammates — Garrus and Thane — have this listed as their preferred way to take down krogan. Most of Thane's elimination techniques boil down to NeckSnap; with krogan he has to re-enact the boxing scene in ''Film/SherlockHolmes2009'' with added violence to deal with the secondary nervous system and so on (with alternate option: "Bomb"). Garrus, meanwhile, preferred to use DeathByIrony — shooting a gunrunner with a smuggled weapon, hurling dangerous drugs into the eyes of a drug smuggler — with the exception of one person, almost certainly krogan, who required being shot ''everywhere'' and third-degree burns.
** In an on-ship dialog, Grunt voices the opinion that this is a sign of respect.
--->'''Grunt:''' I won't disrespect their strength by doing less than the worst to them.
** It is basically standard Turian military doctrine: First give the enemies one chance to surrender. Then hit them as hard as possible and ask again. If they still refuse, wipe them all out. There was some miscommunication when the Salarians developed the [[DoomsdayDevice Genophage]] as a deterrence against the Krogans.
* ''VideoGame/{{Spore}}'' gives you the [[EarthShatteringKaboom Planet Buster]], which is ExactlyWhatItSaysOnTheTin. It works [[https://www.youtube.com/watch?v=T8dvMDFOFnA#t=30m30s like this.]]
* With a sadistic RandomNumberGod controlling everything from behind the scenes, you'll see a lot of Overkill in ''Franchise/FireEmblem''. So you hacked away at that boss's HP, leaving them with exactly 1 HP left? Well, the next unit to attack, which if it would crit (despite having a mere 1% chance to do so) would kill the boss from full HP… promptly will crit. Of course, if your plan is to leave the Boss with a minor bit of HP, so a weaker unit could kill it, the second attack of whatever unit you had sent into the fight to weaken said boss, also will be a crit, killing the boss immediately. Or when your unit did their first attack, leaving the enemy with a minor bit of HP, then they take the enemy's counterattack… that's when the Crit will come. Of course, it all works in reverse. The enemy won't kill your unit practically. They'll crit and overkill you.
** The sacred weapons from ''Sacred Stones'' get x2 bonus when fighting a monster. Crit with that, and that can do damage upwards of 150 damage, easily.
*** Give Joshua a Brave Sword, and, taking the damage he would do against the average enemy, 25 damage, and with his high speed, he would hit four times, giving you 100 damage. Of course, this being Joshua, he will have very high critical chance, leading to a possible 300 damage in one turn. Then if you get Tethys near him, allowing him to move again, he will be able to do a grand total of 600 damage. Per turn.
** Along the same vein are the mastery skills from ''Path of Radiance'' and especially ''Radiant Dawn''. In the former, you have to use up a lot of skill capacity points just to learn them and you only get 4 opportunities per game, but the masteries that inflict damage cut through enemies swiftly whenever they kick in. But lordy, ''Radiant Dawn'' is a whole other beast: all units that promote to tier 3 (and Laguz that use a Satori Sign) get a free mastery skill, and they are ''all'' made of Overkill. Only one or two of them ''don't'' inflict 3-5x more damage, and some have a side effect (put enemy to sleep, etc.) that you're not liable to take advantage of because your hapless victims will usually become DeaderThanDead first.
*** Luna (in ''Dawn'') triples the user's Strength, then negates the foe's Defense, then usually crushes its' victim in one stroke. More or less, there's not a unit in the game that can survive that. ''[[ButWaitTheresMore But!]]'' If that's just not Overkill enough for you, consider the Black Knight's obscene mastery, Eclipse. Same effect, but 5x Strength instead. Based on the Knight's stats, he has a fixed 40% chance to inflict 208 damage. The final boss is 88 HP short of that. Ye gods. [[spoiler:Fortunately, when it comes time to duel the Knight in the final chapter, equipping Nihil shuts down Eclipse (and any other enemy mastery) altogether. If you ''don't'' do this, you are some sort of masochist.]]
*** Trueblades' mastery skill, Astra, allows them to make five attacks instead of one. And with their high Speed, they're very likely to double attack. Give them a Brave Sword and the Adept skill (which causes a unit to attack twice instead of once if it activates), and it would be theoretically possible for them to attack forty times in one battle. Sadly, Astra cannot inflict crits.
** A "Ruin Sage Morgan" (skill build for Morgan as Aversa's son where he's a Dark-wielding Sage equipped with a forged Ruin Tome) — a theorized character in ''VideoGame/FireEmblemAwakening''… embodies this trope: 75 ATK (Magic) with 100% chance of activating vengeance, which can depend on his HP, raise that to 114… and he's got a 100% chance to critical. 342 Damage is quite painful in a game where the maximum HP is 80.
* Most of ''VideoGame/ArTonelicoMelodyOfElemia'''s Song Magic isn't quite so powerful. But then we come across Tower Connection, Silver Horn, Ar tonelico, and Phantasmagoria. The latter two in [[VideoGame/ArTonelicoIIMelodyOfMetafalica the second game]] fire a concentrated laser at the FloatingContinent you're on, which causes an explosion ''larger than the continent itself''. About ''100 times'' larger. Combined with Replakia, which is itself another huge freakin' laser ''much'' closer to the continent than the titular tower, and it's a surprise the same thing that would happen to Lyner if he used [[DeathByGenreSavvy Ar tonelico??]] doesn't happen here.
* In ''Spider-Man 2'', you could climb the highest building in the city while holding a thug, then jump off and ''piledrive the thug to the ground''. In fact, this is the only way to jump from the top of the Empire State Building to the ground without dying.
* ''VideoGame/{{Transcendence}}'' actively promotes this in dealing with the massive capital ship enemies encountered near the end of the game. Of particular note is the Iocrym Fracture Cannon, a weapon that launches an unending torrent of very damaging plasma, which at this stage of the game is essentially one of the two most damaging types of damage. It can then be upgraded to do 350% its original damage rate, which is more than enough to destroy anything in the game.
** This can also be accomplished with jettisoned crates of fuel; putting enough fuel, or ammo, into an unlimited number of crates and then shooting them will create a massive chain reaction of thermonuclear explosions, killing anything viewable in screen with absolute certainty, and beyond, depending on how widely spread the crates are. In theory, one could do this to an entire star system, frying everything instantly and completely.
* In ''VideoGame/UrbanRivals'', Darth of the GHEIST Clan is noted of being too good of a killer, as he is known for using hundreds of bullets, when three would have done, or also using a bazooka at the drop of a hat.
* Barbatos from the [=PS2=] remake ''VideoGame/TalesOfDestiny''. His trademark "No Items Ever!" mystic arte is practically guaranteed to deal five-digit damage regardless of your stats (In a game where the player HP cap is 9999), and his World Destroyer can easily break into six digits range if it's not stopped. Plus, when he gets low on HP, he uses Violent Pain, which increases his attack power dramatically for even more overkill. This in conjunction with World Destroyer and the deliberate use of equipment that increases damage taken can actually make him [[https://www.youtube.com/watch?v=n465NuG5VbE&list=UUMNeAoJz5R-1EHMPE1vxVuw&index=8&feature=plcp hit you so hard that the damage loops back around into the negatives]].
** In his first appearance in ''Tales Of Destiny 2'', he lacks his trademark hi-ougi, but on higher difficulties, will use Execution and extend it into the absurdly overkill Luna Shade spell in response to item usage, which can hit for five-digit damage at a point where you'd likely have slightly over 1K HP.
** On a general ''VideoGame/TalesSeries'' note, getting hit with a mystic arte/hi-ougi from a boss on the highest difficulty will generally deal damage that exceeds your current HP maximum by a significant degree if you're fighting them at the appropriate level.

* The final boss of ''VideoGame/{{Descent}} II'' features a colossal green robot that is ''completely'' invulnerable to all frontal attacks and sports ''dual'' rapid-fire homing earthshaker missile launchers that he uses quite liberally. The earthshaker missile is a fusion of the smart missile and the [[PenultimateWeapon mega missile]] turned ''up to eleven''. In mere seconds of him spotting you, you can expect to have anywhere from 2 to 10 shaker missiles quickly closing in on your position. [[https://www.youtube.com/watch?v=Jh83OXQ8GeY God help you if they miss.]]
* ''VideoGame/AssassinsCreedBrotherhood'' isn't quite as over-the-top as many examples on this page, but one move has to stand out — stabbing a guard through the underside of the head, then firing the Hidden Gun at point-blank. The former would be a fatal wound in RealLife, and remember that the latter can punch through [[HeavilyArmoredMook Brute plate]] for a OneHitKill even at maximum effective range. At point-blank, one wonders why the head doesn't [[YourHeadAsplode explode]] or get sent flying.
* In ''VideoGame/TheGodfather'' games, after choking someone to death, Aldo or Dominic seals the deal with a NeckSnap. You can never be too sure, right? Some of the other Execution animations also involve this. For one, the machinegun Execution on a standing target involves hitting him with the weapon butt twice to knock him down, stomping on his neck, and then giving him a belly full of lead.
* The ''Franchise/KingdomHearts'' games are known for absurdly difficult bonus bosses, but the Unknown in ''VideoGame/KingdomHeartsBirthBySleep'' takes the fucking cake. Virtually every attack he's got will reduce you to 1 HP regardless of level, which includes each individual hit from his overly long combos. Get hit with a full combo, and you'll be stunned, aka, deader than dead. Many of his own attacks consist of the most powerful deck commands in the game cranked up to eleven, and to make matters worse, if you do manage to land a good combo on him… he'll just [[JustForFun/TimeLord reverse time]] and proceed to [[TheComputerIsACheatingBastard school you]]. There's Overkill, and then there's the Unknown.
** In a non-lethal variant, ''VideoGame/KingdomHeartsIII'' features a scene in which Vanitas attempts to attack Sora only for [[WesternAnimation/MonstersInc Sulley]] to sneak up on Vanitas, scare him, and then throw him into a door before throwing the door into another door and repeating the process before shredding the last one to ensure Vanitas does not come back.
* In ''[[VideoGame/ModernWarfare Call of Duty 4]]'''s Death from Above, there is nothing more satisfying than using the 105mm to kill a single enemy soldier just because you have the time.
** Strangely enough, a reflection of RealLife. You can find several videos of AC130 missions on youtube; in at least one of them, the gunship is shooting at a lone infantryman who keeps evading the smaller shots by zigzagging around (he only succeeds because the time-to-target is several seconds). Then the gunner gets bored and/or irritated enough to fire the big gun…
* In ''VideoGame/HaloReach'', there is a WaveMotionGun usable in the climax (well, it looks like one; it's actually a [[MagneticWeapons coilgun]] that fires a small slug at hypersonic speeds which subsequently impacts with 1.1 gigajoules of kinetic energy, or about a quarter of a ton of TNT; the "beam" is [[ShownTheirWork a trail of superheated air]]). It can OneHitKill a Covenant battlecruiser if timed right. It can also be used to kill the incoming Phantoms, which in earlier scripted sequences are taken down by small air-to-air missiles and 20mm autocannons. Needless to say, the Phantoms literally shatter when hit. There are also Banshees there, which are [[GlassCannon Glass Cannons]] killable by rifles. Lulz ensue.
** On the topic of tactical bombings, there is a Target Locator. It rarely ever appears, but when it does, it designates an area for an artillery strike. Firing this upon large crowds of [[TheGoomba Grunts]] can prove very pleasing.
* In the ''VideoGame/PennyArcadeAdventures'' games, killing someone with an overkill causes you to kill them in slow motion, and then get a +5% damage bonus. This goes all the way up to +75% in each game, per character.
* ''VideoGame/TheLastRemnant'' has a special combat effect just for that called, guess what, Overkill. It requires someone to be hit by an enemy with about twice as much damage as the defender's HP. While hard to perform on bosses and players, normal creeps often succumb to this. Overkills usually are so powerful, not only the entire Union dies (Unions share HP — if one person gets hit for 3k damage, the entire group is as well), they are blown away like a rag-doll or disintegrated if it was a spell.

* In ''VideoGame/ThreeDDotGameHeroes'', fully upgrading the Giga sword causes the blade, when on full life, to blanket the screen, destroying pretty much everything in its path, even making boss fights on the hardest difficulty mode a cakewalk.
* ''Franchise/TheElderScrolls''
** In ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'', the player can become this by exploiting the ridiculously broken alchemy system. The effectiveness of the potions is determined by intelligence, and you can make potions that increase it. Do this for a while and you'll be making potions so powerful they literally break the game: "Fortify Attack" and "Fortify Strength" can, at this point, allow you to kill the second form of [[FinalBoss Dagoth-Ur]] in one hit even though he is scripted to be invincible, and "fortify speed" makes you so fast the game's physics screw up, letting you run through mountains.
** ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'':
*** Festus Krex is a sorcerer and [[MurderInc Dark Brotherhood]] assassin. Unlike his comrades, he prefers brutally murdering his targets point blank with powerful spells as opposed to stealth and sneaky tactics. If asked for advice on your current mission, he'll recommend this for you as well. Ironically, [[spoiler:when the Dark Brotherhood sanctuary is attacked by the Penitus Oculatus]], Festus is [[spoiler:found pinned to a tree by ''twenty arrows'']].
---> '''Festus:''' ''"Do what I do. Walk up to your target, introduce yourself, melt their skin off, and then run like the wind. Works every time."''
*** [[ANaziByAnyOtherName Thalmor]] documents reveal that "overwhelming force" is their preferred approach to eliminating the surviving [[AncientOrderOfProtectors Blades]] whenever they are found. The Blades are indeed each a OneManArmy, but for a [[FantasticRacism Fantastically Racist]] StateSec order of {{Magic Knight}}s like the Thalmor to decide that overkill is the best option is about as close to a show of respect as they'll give a human adversary.
* ''VideoGame/TriggerKnight'' has the purchasable consumable Divine Edge. It multiplies the damage that your next attack does a thousand times, ensuring that whatever you hit is dead. Even the dragons, which are nigh impossible to otherwise kill.
* Subverted in Rift. There used to be a multi-phase zone event in the Silverwood starting zone where the final objective was to defeat a level 20 raid boss with 200,000 HP, meant to be taken on by a minimum of 15 level 20 characters. After a level 40+ character nearly solo'd the boss, leaving it with less than 1,000 HP before being killed themselves, the developers released a SEVERELY off-schedule emergency patch within just a couple hours that created a new debuff called "Planar Equity". This debuff NEGATES 99% of a character's combat capability against certain enemies unless they're within seven levels of the enemy, or lower level at all. And did we mention that this was a time before the HP system was revamped, so the average HP for a character was somewhere between 7,000 to 8,500?
* ''[[VideoGame/{{X}} X3: Terran Conflict's]]'' [=M7M=] missile frigates use MacrossMissileMassacre as their only form of attack. In player hands, any such vessel can turn entire sectors to rubble ([[ArtificialStupidity the AI doesn't know how to do this]]), but the AGI Task Force's [[GameBreaker Skirnir]] crosses the trope with ThereIsNoKillLikeOverKill, and seasons it with MoreDakka.
** I'll explain. The Skirnir missile frigate has eight launchers for Shadow missiles. Shadow missiles have [[RecursiveAmmo eight warheads]]. Each warhead does 755 MJ of damage. The two toughest ships in the game have a maximum of 12 GJ of shielding. Do the math.
*** Oh, and did I mention the damn Shadows will ''seek new targets if the old one is destroyed before they hit????''
** The Skirnir was such a GameBreaker due mainly to [[GoodBadBugs a typo in the data for the Shadow missile]]. The mistake is fixed in ''X3: Albion Prelude''. Oh well.
** A milder version of this trope comes in the form of the corvette-grade Typhoon Missile. An eight-warhead missile dealing 240 MJ of damage total (each warhead does 30 MJ of damage to stack up). Why is this considered overkill? Because no vessel below the class of M6 corvettes carries 200 MJ of shielding, with the only exceptions being the Argon Eclipse and a few models of the Teladi Falcon, namely the Sentinel variant (the only non-capital ship in the games to mount 400 MJ of shielding or 2 200 MJ shields). While the ones with turrets can at least try to swat off the missiles, one volley is enough to vaporize anything that doesn't come with a turret, and just two or more can easily overwhelm the turreted ones. The missiles, however, can't catch M5 scouts, as they're just too [[GoddamnedBats vexatiously]] [[FragileSpeedster quick]] to draw a lock on.
* Some VideoGame/TowerDefense games sum overkill damage for achievements. [[VideoGame/{{Gemcraft}} Gemcraft Labyrinth]] rewards you with EXP multipliers for large sums each battle.
* The VideoGame/SaintsRow series has this happen every so often.
** When your "Wanted" rating gets high enough, whether from a gang or from the police, they send out the big guns, possibly for just one man. These "big guns" can include genetically-engineered supermen, a FlechetteStorm of grenades, a girl who can FlashStep while DualWielding Uzis… and a tank.
** In ''Saints Row 2'', Mr. Sunshine, TheDragon to the General of the Sons of Samedi, seems to take a lot of bullets before dying — and even gets up after the first salvo. You wind up decapitating him and throwing his head on a conveyor belt leading to a furnace to make absolutely sure.
** If you let the statue in Steelport get blown up in ''VideoGame/SaintsRowTheThird'', the paramilitary group that has declared martial law deploys a massive flying fortress to scrub the town in order to get rid of you once and for all.
** Some of the weapons you can get tend to qualify for this as well… employing a rocket launcher against a single person or even a car, calling an airstrike against someone, deploying a drone to fire a missile at one person… overkill is just another day in the office in Stilwater.
** ''VideoGame/SaintsRowIV'': Are you having trouble with an assassination quest? Get the "Death From Above" power and the "Nuke" upgrade, run up a building, then come crashing down at your target with the force of an atom bomb. The buildings of virtual Steelport may stay standing, but your target sure as hell won't!
* An interesting moment happens in ''VideoGame/SDGundamGGeneration GATHER BEAT'' and its remake ''SD Gundam G-Generation ADVANCE''. At one point, you face [[Anime/AfterWarGundamX the Frost Brothers]] armed with a series of Gundam Xs, one of them piloted by Tiffa Adill. If you played things right, you can actually kill the Frost Brothers ''three times'', all of them scripted moments. The first comes if you had recruited Garrod Ran, who will convince Tiffa, rescue her, take over her Gundam X and turn its Satellite Cannon on the Frost Brothers. The second involves [[Anime/MobileSuitGundam Cucuruz Doan]], who will be taught a SuperMode by [[Anime/MobileFighterGGundam Domon Kasshu]] and attack the Frost Brothers with his newfound abilities in a Zaku. The last one involves [[Anime/MobileSuitZetaGundam Kamille Bidan]] losing control of himself and chopping the brothers with the Zeta Gundam's {{BFS}}.

* In ''VideoGame/{{Infamous}}'', you just restrained an enemy that's been pissing you off and you want revenge? Use a freaking Lightning Storm on them.
* In ''VideoGame/{{Borderlands 2}}'', the Gunzerker class has a skill with this exact name. Whenever the player kills an enemy with a weapon, the excess damage from the last kill becomes bonus damage on the next weapon attack, potentially leading to a constant string of overkill.
** Salvador's Action skill has now become a general perk in ''VideoGame/Borderlands3''. The Guardian Rank Perk "Overkill" applies excess damage from the last kill to the next shot. And this works with ALL characters.
** Downloadable character Krieg the Psycho has a skill called 'Bloodsplosion,' which causes enemies to explode when killed… and enemies killed by that Bloodsplosion add overkill damage to ''their'' explosion. And so on, and so on, and so on. It only stops when there are no more enemies in range of an explosion. It's possible to string a long chain of these explosions sufficient to wipe out any boss that makes the mistake of summoning swarming enemies.
** Gaige the Mechromancer has an ability called Anarchy, which gives her a cumulative 1.75% damage bonus and equivalent accuracy penalty. With the right class mod and the right build, she can stack Anarchy up to six hundred times. That's a ''one thousand percent'' damage bonus. ''Bonus.'' Sure, this causes her accuracy to vanish, but Close Enough lets her rebound shots into the enemy at half damage even if she can't see them, as long as the bullet has a straight ricochet path to the enemy. Give her a Maggie, which in her hands is able to put out 42 shotgun-style pellets in a couple of seconds, and just watch anything that can't resist bullets straight-up ''melt'', even if it's around a corner from her.
* The BonusBoss of ''VideoGame/DigitalDevilSaga'' has a signature move that deals damage of 4-5 orders of magnitude...[[OneHitKill in a system where everyone's HP is hard-capped at 999]]. If you go into the battle with immunity to any particular element on any of your characters, [[BerserkButton he will open the battle with it and instantly wipe you]].
* In ''VideoGame/CityOfHeroes'', if you fail the "burning building" zone event, the building explodes, killing you. It was supposed to deal three ticks of 1000 points of damage, just enough to defeat the strongest characters — but the person designing the explosion accidentally specified it as "1000% damage", meaning 10 times your maximum hitpoints. They left the error in because, well, it got the job done.
** CityOfHeroes was also briefly host to a magnificently stupid glitch that caused attacks to do so much damage that it had to be expressed in ''scientific notation''. For reference, the maximum hitpoints a player character can have is a little over 3200.
* In ''VideoGame/DefenseOfTheAncients'' and the sequel ''[=DotA=] 2'', a hero named Axe has an ultimate ability called Culling Blade. It deals low (150/250/300) magical damage on healthy enemies, but if it lands on a target with health below ability's stated threshold (300/450/625), it instantly deal 100 000 000 physical damage, but not before removing all buffs from the target to stop anything that might save its life. When upgraded with Aghanim's Scepter, the ability's recharge time is lowered from 75/65/55 seconds to just 6 seconds, meaning he can potentially deal 500 million damage if he uses his ultimate on the entire enemy team in quick succession.
** Ancient Apparition, from the same game, has the ultimate ability ''Ice Blast'', which causes its victims to shatter when their health drops below a certain percentage. Like ''Culling Blade'' above, the shatter manifests as 100 million physical damage. Unlike ''Culling Blade'', it's an area of effect ability, letting Ancient Apparition potentially apply it to an entire team at once.
* In ''∀kashicverse: Malicious Wake'', ''you yourself'' can [[TransformationSequence turn into a massive entity with power equal to a boss.]] The most powerful attack you have in this form is a laser with enough range and power to literally kill everything onscreen. You can only use this for a few seconds before reverting to your normal form, but it's powerful enough to drain whole health bars of bosses in mere seconds.
* In ''VideoGame/MarioAndLuigiDreamTeam'', a level 100 player (aka ridiculous overleveled) can go against the weakest enemy in the game (a Gromba), use the time freeze badge combo, then by having the Duplex Crown (for two attacks per turn) unleash Zee Egg and Star Rocket on said enemy non-stop for the equivalent of six attacks. The overall damage? About 99,999. That's '''twelve thousand''' times the enemy's health, and enough to defeat the final boss 41 times over. Ouch.

* ''VideoGame/WorldInConflict'' multiplayer is half teamwork, and half using limited resources efficiently:
** A low-cost tactical aid like the tank buster or airstrike can destroy heavy tanks at full health, but their area of effect is relatively small and must be precisely placed. Overkill comes into play if a player decides to use expensive daisy cutters, fuel-air bombs, heavy artillery barrages, carpet bombing, or '''nukes''' on a disproportionately small number of units, or units already about to be killed conventionally. Laser-guided bombs are moderately expensive and have a tiny AOE (but they are good at leveling buildings), so using them directly on ''any'' unit is overkill.
** Aside from tactical aids, players can also target infantry units with munitions really meant to be anti-vehicle, such as heavy artillery (usually earning a fitting report from the artillery crew, such as "Infantry was annihilated.") or a heavy tank's HEAT shells (which will always kill exactly one soldier).

* ''VideoGame/MurderedSoulSuspect'': Ronan O'Connor is killed by first being [[DestinationDefenestration thrown out of a four-story window]] and then being shot ''seven times'' with his [[HoistByHisOwnPetard own gun]].
* ''VideoGame/RedDeadRedemption'': [[spoiler:How the Army kills John Marston in the end. In fact, the fact that Ross sent ''the Army'' against ''one man'' is an example.]] In a gameplay note, try duelling with the Mauser sometime. Oh, the carnage.
* Taken to ridiculous levels in ''VideoGame/MugenSouls''. Literally EVERY special move counts as this. Let's see, we have: Launching your foes into the sky on a giant beam of light, piercing (and of course destroying) multiple planets in the process and subsequently destroying the sun, [[spoiler:what makes this particular attack even more hilarious is the 'OOPS, I DIDN'T MEAN TO GO THAT FAR' in the end]], slicing planets with a giant sword, opening black holes, summoning giant demons of death, etc, etc. But let's not forget your own special attack - the Peon Ball. Basically a giant ball of energy, which gets bigger (and more powerful) as you get more Peons from fights... let's see... someone made a video of it with size: Galaxy. Yes you're literally able to throw an energy ball the size of a galaxy on your opponent. Also Overkill is literally the only thing you do in late game. You can upgrade your level-limit to 9999, also every item again being able to being upgraded more or less infinite times, lets just say that one-hitting bosses - with your normal attack... isn't all that special once you reach a certain point in the game. As for normal foes... well you do the math.
** One should maybe add that the game actively REWARDS players for going overkill, one of the mechanics is called a Triple-Counter-Stop which triggers when you fill a counter with damage for one attack 3 times, doing so rewards a pretty nice bonus at the end of a battle, in the beginning this counter is at 999 though as with everything in this game it can be upped to ridiculous levels, expect to see numbers like 9999999999 being topped quite easily.

* ''VideoGame/TheLegendOfHeroesTrailsOfColdSteel'':
** An overkill requires you to land a killing blow that deals five times your opponent's remaining HP. It's only a 10% EXP bonus, but it can add up. Because of this, it sometimes makes sense to drag out the battle a bit to weaken the enemy enough to have a better chance of landing the overkill. Later on in the game, a great way to get overkills is to use the "Burst" link ability, which causes all of your characters to attack every target on the battlefield. What's great about it is that they will continue to strike even when the enemies are already K.O.ed, which counts as an automatic overkill. Applied correctly, you can easily land large multiple overkill bonuses, as well as other ones such as Vanquisher (40% EXP bonus for killing four or more enemies at once), Unscathed (20% bonus for taking no damage during the fight), and Swift and Sure (10% bonus for winning within three turns). The only catch is that you can only get a max of 9999 EXP per fight.
** For a cutscene example, in ''Cold Steel III'' Rean delivers this towards the FinalBoss of the game by hacking at it over and over again ''long after it's dead''.
** The Divine Knight / Panzer Soldat battles feature a mechanic where if your main attack is enough to finish off the enemy's remaining HP, then the follow-up attack screen will be presented, except all of the command buttons will change to the option for the most powerful follow-up attack you have in your arsenal. This occurs even if you don't have the BP (brave points) that would normally be required to use this. More specifically, your normal options are "Follow-Up" (no BP cost and builds up 1 BP), "Finisher" (3 BP cost, and unleashes a powerful single character finishing move) and Unite (5 BP cost and unleashes a powerful joint attack). Under this mechanic, all choices change to "Unite."
* In ''VideoGame/WorldOfWarships'', aircraft carriers are such a danger to the opposing team (if for nothing else than their ability to have their aircraft spot enemies otherwise hiding from surface vessels) that if one happens to be caught within range of multiple enemy units, it's not unusual to see every ship within range fire everything they have at it, even if it looks like it's about to be finished off anyway.
* In ''VideoGame/{{Overwatch}}'', using your ultimate to kill one person can be this depending on the ultimate. D.VA is probably the best example. Her Self-Destruct ultimate is the single largest explosion in the game and is an instant kill on anyone in its radius who hasn't got behind cover. Most of the time D.VA will save it to hit as many enemies as she can... but if you really want someone dead, cornering them and hitting Self-Destruct is a good way to turn them into a fine red paste. (Even better if they're asleep from Ana's Sleep Dart ability - so long as you don't attack them, they'll know what's coming and be utterly powerless to even try to get to cover.)

* ''VideoGame/StarFox64'' has the boss of Area 6, Gorgon, a weapon designed to ''[[EarthShatteringKaboom destroy planets]]'' being used to defend Venom from Star Fox's four Arwing fighters. Justified, in that Area 6 is Venom's front line of defense, Star Fox ''[[MookHorrorShow smashed]]'' through it, and [[GodzillaThreshold the Venomian army's options have been exhausted at this point]].
* ''VideoGame/{{Terraria}}'': Some players try to slaughter bosses or armies of event monsters in as little time as possible, leading to such ridiculousness as [[https://youtu.be/Ppy-d8wQAOE?t=28s killing Duke Fishron in a fraction of a second]] with a [[MacrossMissileMassacre giant wall of firework launchers]].
** Bringing Hardmode gear, especially late-game weapons, into a pre-Hardmode world generally qualifies. There's nothing quite like using the Nebula Blaze to vaporize slimes or reducing the Eye of Cthulhu to Swiss cheese nigh-instantly with the Vortex Beater.
* In ''[[VideoGame/FateExtra Fate/Extra CCC]]'', Gilgamesh's Noble Phantasm is this. It can only be used against a target that has 30% or less of their maximum HP remaining, ALWAYS hits the damage cap (Nothing in the game has that much HP, not even the Final Boss), and to top it all off, always applies a OneHitKill effect on top of that! The only thing that could stop it from being overkill is the fact that '''no enemy in the game, not even the final boss or bonus bosses, is immune to it,''' so it could be used to execute a particularly tough enemy if you've not been grinding (Not that a fight should ever be close with [[GameBreaker Gilgamesh]]).
* ''VideoGame/FateGrandOrder'':
** Mecha Eli-Chan and Mecha Eli-Chan [=MkII=]'s Noble Phantasm, "Breast Zero Erzsébet: Soaring Metallic Demoness", has them fire an absurd amount of missiles and lasers, followed by a WaveMotionGun, at ''one target''. Their profiles even comment on how excessive the attack is.
** The Berserker version of Miyamoto Musashi mentions an incident where she defeated an opponent by luring him to an island, then blowing it up.
* The scoring mechanics of ''VideoGame/BloodOver'' is built around this trope; players can defeat enemies through their attacks, but they can also fill up a red bar where the enemies' blue life bar used to be by attacking them before they disappear upon defeat. Doing so will not only yield more score but also builds up your Blood Meter quicker and allow you to use Akari's help from her Gatling gun or perform Shou's super attack. Mastering this system is also key to reaching the true ending route.
* One mission in ''VideoGame/ValkyriaChronicles'' demands that you ''don't'' adhere to this trope for the mission's boss unit, an APC carrying a captive Princess Cordelia. Specifically, hitting the APC with any kind of explosive like you would for any other vehicle will cause it to explode, killing Cordelia. Instead, the player has to get behind it and shoot out the [[AttackItsWeakPoint radiator]] with normal firearms, disabling it instead.
** It's entirely possible, though [[AwesomeButImpractical often impractical]] due to tanks lacking the pinpoint accuracy necessary, to kill an infantry unit by shooting it with a tank shell. Enemy tanks will often attempt this against your own units, usually if the Edelweiss or Shamrock aren't around for it to fire at. The same is also true of Lancers and their anti-tank Lances (the game's equivalent to rocket launchers,) though Lancers do eventually get the option to equip their lances with anti-personnel mortar rounds instead.
* The standard ''VideoGame/PuyoPuyo'' board can hold up to 71 pieces without triggering a loss. However, not only is it possible to queue up more than that to your opponent's board, but [[https://puyonexus.com/wiki/Nuisance_queue unique symbols exist]] for attacks of 180, 360, 720, and even ''1440'' garbage pieces. ''Puyo Puyo Yo~n'' takes it up to eleven with unique symbols for millions and even ''a trillion'' garbage. Of course, the whole point is to have your own big chain ready to counterattack with, but if you don't have one...YouAreAlreadyDead.
* Humans in ''VideoGame/PeoplePlayground'' can't take much damage and you can kill them by just shooting them with a pistol, or beating them up with some baseball bat. But nothing prevents you from using more overpowered and destructive weapons like a railgun, tank, or [[NukeEm nuclear bomb]].
* Most ultimate abilities in ''VideoGame/LeagueOfLegends'' are pretty tame and reasonable in-game. Urgot's ultimate stands out among the rest, and even among the other executions. If his opponent is in execution range, he fires chains at them that drag them toward his whirling spike wheels in his abdomen. It's just slow enough to make the execution a show. When someone like Lux, who is a cute and happy mage girl, gets dragged into the spikes and [[NotEnoughToBury her body is reduced to a bloody paste by his ultimate]], it's pure NightmareFuel.
* ''VideoGame/AvoidTheNoid'': How do you destroy a pizza? Of course, you take out a ''bazooka''.
* In ''VideoGame/DeadSpace2'', one of the [=EarthGov=] weapons you can ultimately arm Isaac with is a high-velocity rifle outfitted explosive rounds. You're thinking it's some kind of anti-tank rifle, right? It's actually meant for use on ''human targets''. Specifically, it's a "riot suppression" weapon... in the sense that it "suppresses" the riots by blowing multiple targets into gory chunks per shot until the survivors surrender out of fear of being blown into kibble themselves.
* ''VideoGame/KeinegedAnNor'': Several deaths. The most painful one has to be the black scorpion which stings you 153 times.
* ''VideoGame/OctopathTraveler'':
** If you boost to attack multiple times, even if the first attack technically depletes the enemy's HP to zero, your character will still use all of their attacks before allowing the enemy to die.
** The Divine skills of Warmaster and Runelord has them consecutively unleash every single weapon type and magic element, respectively, against the enemy.
* ''Videogame/NuclearThrone'': The Hyper Crystal boss deals 200 contact damage, where the maximum health you'll get never exceeds 25. Appariently, touching the Hyper Crystal would be like having said touching limb stretched infinitley into the next dimension instantly acording to the developer.
* ''VideoGame/LoveOfMagic'': MC's modus operandi once he gets access to the Mantle, as shown when he calls an immense amount of fire down on Mitburgh.
--> '''MC''': My coach used to say that ''overkill'' is something only the other guy complains about. But he was an old Marine, so that probably had something to do with it.
* In ''[[VideoGame/{{Hitman2016}} Hitman (2016)]]'', the final main story mission in Hokkaido features one target, [[spoiler: Erich Soders]], who is on the operating table awaiting a heart transplant. Most of the opportunities involve killing the target on the table, but one involves destroying the donor heart and leaving the target to die unable to get a new donor heart instead. Two challenges involve both destroying the heart and killing the target on the table. The one for killing the target on the table first [[ExactlyWhatItSaysOnTheTin is even called "Overkill;"]] the one for destroying the heart first is a LampshadeHanging called "I Think [[spoiler: He's]] Dead Now."
* The entire shtick of ''VideoGame/KillItWithFire''. Your task? Exterminate creepy, but harmless [[SpidersAreScary spiders]] infesting normal apartments. Your tools? [[MoreDakka Guns]], [[StuffBlowingUp explosives]], and of course, [[KillItWithFire fire]].
* Dark Force's usual method of planetary conquest in ''VideoGame/{{Extrapower}}'', coordinating multiple orbital laser strikes to gut a planet's defenses and spirit at once. In ''VideoGame/ExtrapowerStarResistance'', Galaxy Star's transcendental ability is this: him and the entire Galaxys team flood the screen with their entire arsenals at once.
* The goal of the ''VideoGame/BloonsTowerDefense'' series is simply to pop incoming balloons and sometimes shoot down blimps. The tools the game offer you to do so later in the game include experimental firearms, magic, chemical weapons, armed military craft, {{Wave Motion Gun}}s, {{Killer Robot}}s with antimatter cannons, {{Physical God}}s, [[FantasticNuke nuclear warheads]], and more.

* In ''VideoGame/SymphonyOfWar'', if there is only one enemy left on the opposing side with minimal HP, your troops will still hit them with all their attacks well after their HP is gone.
* In ''VideoGame/JetSetRadio'', DJ Professor K gets a letter from someone named Mr. Osaki, who asks him how to get rid of a roach infestation in his house (why he would ask a DJ instead of a pest control professional is anyone's guess). Prof. K jokingly suggests that he burn his house down. Unfortunately, he gets another letter from Mr. Osaki who's revealed that [[AdviceBackfire he went and did just that]].

** Special mention has to go to the sequel, specifically the final mission's ending. [[spoiler: After Vader attacks Juno, Starkiller believes her to be dead which unlocks an insane fury within him. Starkiller utilizes the lightning on Kamino after he disarms Vader in his lightsaber duel with him. The way he fires an unending barrage of lightning on Vader brings his former Sith Master to his knees who is unable to defend himself from this attack. The life bar can't even go down any further as Starkiller advances onto him, unleashing more and more rage, until Vader finally collapses to his knees, [[CallForward breathing shallowly and weakly after being inflicted by Force Lightning]] as he will do [[Film/ReturnOfTheJedi years later.]]

** ''VideoGame/CapcomVsSNK2MarkOfTheMillennium'' even gave some people special winposes for finishing with certain supers ([[VideoGame/TheLastBlade Hibiki Takane]] with her "[[DiagonalCut No Fear Feint]]" and [[VideoGame/FatalFury Rock Howard]] with Raising/Raging Storm or Deadly Rave). Chun-li blushes (after her "Yatta" pose) whenever she finishes her opponent with a Finest KO, aka overkill.

** Its sequel, ''Turok 2: Seeds of Evil'', actually managed to ''[[UpToEleven top it]]''. Because hunting dinosaurs requires heavy firepower. Aside from the usual final-game devastators, a particular mention goes to the Cerebral Bore, which fires shots that embed themselves in your enemy's skull. Then they start ''drilling''. Then they [[YourHeadAsplode explode]]. One-shot-kill everything.

*** The unique Fat Man called "Big Boy" can fire 2 mini-nukes at the cost of one. give it the MIRV mod and it will fire [[UpToEleven 16]] for the cost of one. Questions need being asked if something survives that.

*** To realize [[UpToEleven the true scale]] of Supreme Commander's overkill, you must also know that stationary nuke launcher deals 75000 damage[[labelnote:note]]Experimental nuke deals ''1000001 damage''[[/labelnote]] which only two experimentals can survive (as for Forged Alliance while little to no people play vanilla), and most other units do not have even half of this much health. Especially usual targets for nukes — bases with factories and resource production buildings which all are less than 10000 hp, and toughest regular units are battleships with about 50000 hp depending on faction.

*** In ''VideoGame/SuperSmashBrosUltimate'', [[UpToEleven it gets even crazier]]. This game allows you to use a new feature called "Final Smash meter", which functions the way any other fighting game's super meter would. Combine this with how crazy the Final Smashes can get, and matches with these get so flashy, they could outshine Las Vegas. However, it doesn't go too over-the-top — only one Final Smash can be used at a time.

*** Both [[UpToEleven get topped by]] ''Agarest Senki 2'' [[https://www.youtube.com/watch?v=OXJq7akpeYc where they unleash]] an Ultimate Strike, ''and a [[FinishingMove Finish Strike!]]''

*** Luna (in ''Dawn'') triples the user's Strength, then negates the foe's Defense, then usually crushes its' victim in one stroke. More or less, there's not a unit in the game that can survive that. ''[[ButWaitTheresMore But!]]'' If that's just not Overkill enough for you, consider the Black Knight's [[UpToEleven obscene]] mastery, Eclipse. Same effect, but 5x Strength instead. Based on the Knight's stats, he has a fixed 40% chance to inflict 208 damage. The final boss is 88 HP short of that. Ye gods. [[spoiler:Fortunately, when it comes time to duel the Knight in the final chapter, equipping Nihil shuts down Eclipse (and any other enemy mastery) altogether. If you ''don't'' do this, you are some sort of masochist.]]

* The final boss of ''VideoGame/{{Descent}} II'' features a colossal green robot that is ''completely'' invulnerable to all frontal attacks and sports ''dual'' rapid-fire homing earthshaker missile launchers that he uses quite liberally. The earthshaker missile is a fusion of the smart missile and the [[PenultimateWeapon mega missile]] turned ''UpToEleven''. In mere seconds of him spotting you, you can expect to have anywhere from 2 to 10 shaker missiles quickly closing in on your position. [[https://www.youtube.com/watch?v=Jh83OXQ8GeY God help you if they miss.]]

* The ''Franchise/KingdomHearts'' games are known for absurdly difficult bonus bosses, but the Unknown in ''VideoGame/KingdomHeartsBirthBySleep'' takes the fucking cake. Virtually every attack he's got will reduce you to 1 HP regardless of level, which includes each individual hit from his overly long combos. Get hit with a full combo, and you'll be stunned, aka, deader than dead. Many of his own attacks consist of the most powerful deck commands in the game [[UpToEleven cranked up to eleven]], and to make matters worse, if you do manage to land a good combo on him… he'll just [[JustForFun/TimeLord reverse time]] and proceed to [[TheComputerIsACheatingBastard school you]]. There's Overkill, and then there's the Unknown.

* ''[[VideoGame/{{X}} X3: Terran Conflict's]]'' [=M7M=] missile frigates use MacrossMissileMassacre as their only form of attack. In player hands, any such vessel can turn entire sectors to rubble ([[ArtificialStupidity the AI doesn't know how to do this]]), but the AGI Task Force's [[GameBreaker Skirnir]] takes the trope UpToEleven, crosses it with ThereIsNoKillLikeOverKill, and seasons it with MoreDakka.

* [[UpToEleven Taken to ridiculous levels]] in ''VideoGame/MugenSouls''. Literally EVERY special move counts as this. Let's see, we have: Launching your foes into the sky on a giant beam of light, piercing (and of course destroying) multiple planets in the process and subsequently destroying the sun, [[spoiler:what makes this particular attack even more hilarious is the 'OOPS, I DIDN'T MEAN TO GO THAT FAR' in the end]], slicing planets with a giant sword, opening black holes, summoning giant demons of death, etc, etc. But let's not forget your own special attack - the Peon Ball. Basically a giant ball of energy, which gets bigger (and more powerful) as you get more Peons from fights... let's see... someone made a video of it with size: Galaxy. Yes you're literally able to throw an energy ball the size of a galaxy on your opponent. Also Overkill is literally the only thing you do in late game. You can upgrade your level-limit to 9999, also every item again being able to being upgraded more or less infinite times, lets just say that one-hitting bosses - with your normal attack... isn't all that special once you reach a certain point in the game. As for normal foes... well you do the math.

* The standard ''VideoGame/PuyoPuyo'' board can hold up to 71 pieces without triggering a loss. However, not only is it possible to queue up more than that to your opponent's board, but [[https://puyonexus.com/wiki/Nuisance_queue unique symbols exist]] for attacks of 180, 360, 720, and even ''1440'' garbage pieces. ''Puyo Puyo Yo~n'' takes it UpToEleven with unique symbols for millions and even ''a trillion'' garbage. Of course, the whole point is to have your own big chain ready to counterattack with, but if you don't have one...YouAreAlreadyDead.

* In ''VideoGame/JetSetRadio'', DJ Professor K gets a letter from someone named Mr. Osaki, who asks him how to get rid of a cockroach problem in his house (why he would ask a DJ instead of a pest exterminator is anyone's guess). Prof. K jokingly suggests that he burn his house down. Unfortunately, he gets another letter from Mr. Osaki who's revealed that [[AdviceBackfire he went and did just that]].

* In ''VideoGame/JetSetRadio'', DJ Professor K gets a letter from someone named Mr. Osaki, who asks him how to get rid of a cockroach problem in his house (why he would ask a DJ instead of a pest professional is anyone's guess). Prof. K jokingly suggests that he burn his house down. Unfortunately, he gets another letter from Mr. Osaki who's revealed that [[AdviceBackfire he went and did just that]].

* In ''VideoGame/SymphonyOfWar'', if there is only one enemy left on the opposing side with minimal HP, your troops will still hit them with all their attacks well after their HP is gone.

* The goal of the VideoGame/BloonsTowerDefense series is simply to pop incoming balloons and sometimes shoot down blimps. The tools the game offer you to do so later in the game include experimental firearms, magic, chemical weapons, armed military craft, {{Wave Motion Gun}}s, {{Killer Robot}}s with antimatter cannons, {{Physical God}}s, [[FantasticNuke nuclear warheads]], and more.

** And if you use the new Game Plus option, you could potentially have endgame-level characters at the start of the game, in areas where even special 'strong' enemies would be at level 10. At best. If you do multiple playthroughs, or even just grind hard enough, all your characters could be at the level cap of 99.

* ''Franchise/{{Pokemon}}'': While not entirely the fault of the game itself, moreso that of the player, but there's nothing quite as satisfying as roasting a Lv. 2 Caterpie with a Lv. 100 Charizard with max Special Attack, using the strongest Fire-type attack in the game… and scoring a critical hit. It's even worse when you use Psychic with a Lv. 100, max-Special-Attack Mewtwo against a Lv. 2 Weedle… and still get a critical hit.

** Heck, the third game's main combat gimmick is all about overkill. Overkilling an enemy raises your "noise" level by the amount you overkilled them with.

* In ''VideoGame/NoMoreHeroes'', after hitting a {{mook}} enough times, Travis can perform a special move that decapitates the {{mook}}, showering Travis in blood and coins. This becomes practical later in the game — said special move can also decapitate/split in half other mooks nearby, resulting in multiple showers of blood and coins.
** Once he's been knocked down to half health, BonusBoss Henry gains an unbelievably awesome OneHitKO move. Describing it would fail to capture the ludicrousness, so here's a [[https://www.youtube.com/watch?v=ZNsyofCN-a4 link instead]].
** In ''VideoGame/NoMoreHeroes2DesperateStruggle'', Shinobu likes to [[OffWithHisHead cut off heads]] and then ''cut the heads into pieces''. [[spoiler: Given what Destroyman came back from, it might not actually be that unreasonable.]]

** [[FourX 4X]] games in general seem to lend themselves well to practical demonstrations of this trope. ''VideoGame/MasterOfOrion II'', for example, has a device that [[EarthShatteringKaboom blows planets apart]], ''a la'' the [[StarWars Death Star]]. For when you absolutely, positively have to kill every last living thing bigger than a microbe.
*** You don't even need superweapons: A lot of 4X games in which you need total military victory will end with a superweapon, some solopwnmobiles, and a swarm of normal units charging that one final enemy unit to finish him off and win. And it makes sense: What else should they be doing after all?
* The ''VideoGame/{{Mercenaries}}'' series offers the choice of overkill, especially once more powerful airstrikes become unlocked. Sure, you could just run up to the target, shoot him, and then verify him, but it's much more fun to watch the entire city block he's hiding in get blasted to hell by a carpet bombing run.

* ''VideoGame/XenobladeChronicles1'': During the final fight against Gold Face/Egil, you'll eventually get a [[CombatClairvoyance vision]] of him about to use [[spoiler:Bionis Slash X]], which, if it's not stopped in the allotted time, will do ''infinite damage'' to [[spoiler:Bionis]], causing a NonStandardGameOver.

* Dark Force's usual method of planetary conquest in {{Franchise/Extrapower}}, coordinating multiple orbital laser strikes to gut a planet's defenses and spirit at once. In ''VideoGame/ExtrapowerStarResistance'', Galaxy Star's transcendental ability is this: him and the entire Galaxys team flood the screen with their entire arsenals at once.

** The sacred weapons from ''Sacred Stones'' get x3 bonus when fighting a monster. Crit with that, and that can do damage upwards of 150 damage, easily. When your characters' health all max out at 60, it's not uncommon to one-hit-kill an enemy 3-4 times over. And of course, the above rule applies as well.

*** Trueblades' mastery skill, Astra, allows them to make five attacks instead of one. And with their high Speed, they're very likely to double attack. Give them a Brave Sword and the Adept skill (which causes a unit to attack twice instead of once if it activates), and it would be theoretically possible for them to attack forty times in one battle. And then you add in their high chance of getting a critical hit…

* The goal of the VideoGame/BloonsTowerDefense series is simply to pop incoming balloons and sometimes shoot down blimps. The tools the game offer you to do so later in the game include experimental firearms, magic, chemical weapons, armed military craft, {{Wave Motion Gun}}s, {{Killer Robot}}s with antimatter cannons, {{Physical God}}s, [[FantasticNuke nuclear warheads]], and more.

** In addition, Akuma players especially like to finish off opponents with his Shun Goku Satsu move (Translates to "Instant Hell Murder", also known as [[FanNickname The Raging Demon]]) which is possibly one of the most satisfying, and most predictable, moves in fighting game history. Pulling this off results in a ''giant burning 'Ten' symbol'' covering the screen in addition to the standard 'Flash', mirroring the one on Akuma's back. Taken to its logical conclusion by [[https://www.youtube.com/watch?v=wzDxLUcji3Y&t=1m55s Tokido]].

* Dark Force's usual method of planetary conquest in {{Franchise/Extrapower}}, coordinating multiple orbital laser strikes to gut a planet's defenses and spirit at once. In ''VideoGame/ExtrapowerStarResistance'', Galaxy Star's transcendental ability is this: him and the entire Galaxys team flood the screen with their entire arsenals at once.

** The second biggest overkill weapon, the funky bomb, when it lands, sends out up to 10 other bombs in random directions. It then explodes one more time the size of a baby nuke. Unless the target has good shields, it is NOT surviving that one.

* Before them all came ''VideoGame/{{Turok}}''; a series of games that lived and breathed this trope. The original game had the ''quad-rocket launcher'', [[ExactlyWhatItSaysOnTheTin which fired off four]] [[MoreDakka high explosive missiles at once]] - and it was one of the ''weaker'' weapons in your inventory. The ''fusion cannon'' was basically a tactical nuke-cross-{{BFG}} that decimated everything within a square-kilometre in a bright red flash. The... You know what? [[https://www.youtube.com/watch?v=5sIDUv4RtGg Just watch this]].

** The canonical ending for ''Tiberian Dawn'' requires the GDI commander to do that to the Nod Temple -- unlikely in the [[StoryAndGameplaySegregation videos, in the actual gameplay]] a single Ion Cannon blast ''can't'' destroy a Temple... and the Brotherhood repairs the Temple quickly enough that by the time the Ion Cannon has reloaded, the Temple is fully repaired.
** Hell, even the superweapons need a special mention - the GDI superweapon in the third is not one, but [[NukeEm EIGHT lasers fired at once from outer space]]. You can write your name on your enemy's base... [[KillSat with Particle Cannons]].

** The Shogun Executioner in ''VideoGame/CommandAndConquerRedAlert3'' - a giant tripod with three bodies, each of which is armed with a LaserBlade. It's also healed by electricity, and many of your enemies in this level are armed with [[LightningGun Tesla coils]]. Oh, and it's tall enough to knock helicopters out of the sky just by walking into them. You can lose it, though, if not careful.
** Used for Drama in Tiberium Wars when Director Boyle authorizes the use of a Liquid Tiberium Bomb against the Scrin. General Granger (your commanding officer) notes that it is still possible to win through conventional methods and that the Bomb would have irrecoverable consequences if you use it in such a high-saturated tiberium zone. Sure enough, if you choose to use the bomb, not only is every single soldier under your command killed, but also several innocent people in yellow zones across the earth. Red Zones also spread to unprecedented levels, leaving much of the world either homeless or dead, all to take out what was later revealed to be nothing more than ''a worker fleet''.
** In the final mission of Tiberium Wars: Kane's Wrath you get control of all three factions of Nod at once. This means you could build ''three'' copies of the Redeemer Epic unit when a single one would be more than enough to finish the mission, not to mention combining the best units from each of the armies. Unfortunately, by this point in the mission, you'll likely have destroyed most of the opposition and a timer countdown to failure would have also started (Kane specifically sends you these forces because the Macguffin is about to implode and you need to leg it), so there's not much to use the massive army on.

** ''VideoGame/KillerInstinct'' and its sequel introduces, as well as the standard fatalities and humiliations; Ultimate combos, which automatically end with a fatality, and Ultra combos, which can escalate the hit counter somewhere into the upper eighties. Of course, the only time you can pull off either of these is when your opponent has barely enough health to survive a standard combination...
*** Of note is one of Fulgore's finishers. The screen darkens, he pulls off his (normal-sized) head... and out pops a machine-gun turret worthy of sitting atop a literal tank, let alone a robot. [[FridgeLogic I wonder how he fit it in the regular head?]]

** And then there's the infamous x10 mod, which is best described as "Overkill: the GameMod." As the name suggests, the mod takes the attributes of every weapon in the game and multiplies them by ten. Rocket launchers that fire [[MacrossMissileMassacre thirty rockets at once]], knives that stab about ten times a second, Demoknights that can charge across an entire map and ShieldBash for several hundred damage... you get the idea.
*** You thought x10 was overkill? Wait until you see x20! Or x50! x100! And yes, it goes further and further.

*** Knights of the Round is the strongest summoning in the game, using multiple attacks in one animation to circumvent the 9999 damage cap. Its animation takes about 1:15 minutes. W-Summon means you can use a Summoning twice in one round. Mimic lets a character... well, [[ExactlyWhatItSaysOnTheTin mimic the action of another]]. Putting this together, we get 6 [=KotR=] summonings in one round by letting one character do the W-Summon with the other two mimicking him. Of course, this has a drawback -- you can easily get up, make yourself a sandwich and eat it before continuing with the game without missing anything apart from animations of monsters being hacked to ''very'' fine bits.

** ''VideoGame/FinalFantasyXII''':
*** Quickenings. One can easily enough get the first Quickening for everyone in the party within the first hour or so of gameplay. You can one-shot most of the bosses AND their minions without ever getting touched.

** In ''VideoGame/FinalFantasyTactics'', TakeYourTime + LevelGrinding = massive amounts of overkill for story battles, since they always have a default level. The downside to being able to drop a Meteor on, say, [[TheScrappy Algus]] is that quite a few of the random encounters afterward (why ''hello'', Mr. [[DemonicSpider Red Chocobo!]]) have the potential to unleash similar amounts of overkill on your party.

** In a straighter example, killing any regular {{mook}} with your most potent weapons (such as the missile combos in the ''VideoGame/MetroidPrimeTrilogy'' - which include a flamethrower, an ice bomb, and a ''black hole'', among others).

* In the shooter ''VideoGame/CallOfJuarez'', Reverend Ray can initiate a BulletTime mode at will, causing you to draw your six-shooters and have your crosshairs go towards the center from left and right... allowing you to practically kill an enemy, use the BulletTime, and then unload 12 bullets in them.

** Unless you actually target the enemy base, the titan will just fall to attrition, as it will constantly attack units if they attack them, meaning if you continuously make and send just one unit at the titan at a time, it will eventually die with you little closer to defeat. It'll still cost a lot of resources though...
*** [[PuzzleBoss Titans have no anti-air defense.]] Air units with an attack are hard to come by - the Atlanteans have Stymphalian Birds, the Egyptians have Phoenixes - but [[GameBreaker game-breaking]] if you plan to get them.

* The combat system of ''VideoGame/TheForceUnleashed'' is practically built around this entire concept, although special mention must go to the ability to [[spoiler:hold a stormtrooper in the firing path of the DEATH STAR.]]

* Recurring [[BonusBoss Optional Boss]] Iseria Queen from Creator/TriAce's games is almost inevitably based around this - of course, since she's a boss, YOU are at the receiving end. Perhaps the best example is her appearance in ''VideoGame/ValkyrieProfile''... her standard attack is a 25-hit combo, each strike dealing damage above your characters' Max Possible HP. Don't ask about her Special Attacks.

*** The Fat Man example is diegetically encouraged in the Reunions quest of ''Fallout 4''. The armory of Fort Hagen, which is trivially easy to get into if you scrounged around the dungeon proper, contains one Fat Man and one mininuke, and you find it right before you face [[spoiler: Kellogg, the man who killed your spouse and kidnapped your son, who laughs at your helplessness in getting him back]]. Said boss appears in a room that is just wide enough that a mini nuke shot around the far side of it will fry him and his minions while leaving you unharmed. Considering [[PapaWolf the current]] [[MamaBear mentality]] of the player character at the time, one can easily picture them literally nuking the room the moment the boss is finished taunting them.

** Gauss weapons are great for dealing with armored targets like robots. The Gauss rifle is the logical step up, and both the pistol and rifle are from ''Fallout 2''. But ''VideoGame/{{Fallout Tactics|BrotherhoodOfSteel}}'' takes things towards the logical extreme with the gauss minigun, which has fairly long range for a minigun, tears through huge groups of (high-powered) enemies like they were nothing, and is more powerful than the Browning M2. [[TooAwesomeToUse It also eats ammo like popcorn so you'll be saving it for the endgame.]]

* In ''VideoGame/SupremeCommander'', there's nothing like inundating your opponent's base with Tier 3 stationary cannons situated on the other side of the map, watching as their shields collapse and their buildings explode...unless it's queuing up a bunch of nuclear warheads that overwhelm their anti-missile defenses and reduce their base to a lifeless smoking crater.
** In some cases this isn't really ThereIsNoKillLikeOverkill so much as you ''must'' have twice as many nukes simultaneously striking the target as the enemy has strategic missile defense silos ''plus one'' in order to hit, because each defense can shoot down two incoming missiles before impact... though that doesn't stop you from building many more silos [[Film/{{Aliens}} "just to be sure"]].
*** To realize [[UpToEleven the true scale]] of Supreme Commander's overkill you must also know that stationary nuke launcher deals 75000 damage[[labelnote: note]]Experimental nuke deals ''1000001 damage''[[/labelnote]] which only two experimentals can survive (as for Forged Alliance while little to no people play vanilla), and most other units do not have even half of this much health. Especially usual targets for nukes - bases with factories and resource production buildings which all are less than 10000 hp, and toughest regular units are battleships with about 50000 hp depending on faction.

* ''VideoGame/WorldOfWarcraft'' has the Warrior class, whose Execute ability is typically the strongest single attack, and burns all of their Rage to make it ''more'' powerful - but can only be used on opponents under 20% HP. It's, [[ExactlyWhatItSaysOnTheTin well...]]

** However, despite the overkillness of those abilities - against bosses, who will still have a ton of health despite being at 20%... these can really win it for you in PlayerVersusEnvironment fights.
** Even ''Priests'' get one of these, with a twist. Shadow Word: Death is a finishing move that causes a huge amount of damage... but if you ''don't'' kill the enemy with it, you take the damage as well. Since Priests are so squishy, the spell often ends up [[ExactlyWhatItSaysOnTheTin doing what it says on the tin]] either way. (Mostly, this is due to its instant cast and faster cooldown.)
** C'thun Green Beams. Imagine the standard chain lighting spell, except it doubles in damage each time it hits. If you screw up on starting the fight, the last person will be hit for several tens of millions, at the time the boss was released, that's many times your maximum health.

** This is actually a very useful strategy for speedruns in that area (and pretty much mandatory if you want the best item to drop at the end). It also has elements (pun not intended...) of ElementalRockPaperScissors, since the type of damage dealt sets the bodypart dropped- for example, Spooky damage "Scared the [enemy] so much he left his skull behind!"

*** In ''VideoGame/SuperSmashBrosUltimate'', [[UpToEleven it gets even crazier]]. This game allows you to use a new feature called "Final Smash meter", which functions the way any other fighting game's super meter would. Combine this with how crazy the Final Smashes can get, and matches with these get so flashy, they could outshine Las Vegas. However, it doesn't go too over-the-top-- only one Final Smash can be used at a time.

** GuestFighter VideoGame/{{Bayonetta}} is notable for having a Final Smash that provides a ''guaranteed'' kill (as opposed to merely an ''almost''-certain kill by sending the victim flying at absurd velocities): she summons the demon Gomorrah from Hell itself to devour her unfortunate enemies. They get a nasty bite if they're under 100% damage, but if they're over 100% damage, Gomorrah simply [[SwallowedWhole swallows them whole]] and returns to Hell with them for an instant non-standard KO.

* ''Franchise/{{Pokemon}}'': While not entirely the fault of the game itself, moreso that of the player, but there's nothing quite as satisfying as roasting a Lv. 2 Caterpie with a Lv. 100 Charizard with max Special Attack, using the strongest Fire-type attack in the game... and scoring a critical hit. It's even worse when you use Psychic with a Lv. 100, max-Special-Attack Mewtwo against a Lv. 2 Weedle... and still get a critical hit.

** One example that actually happens in-game comes in ''VideoGame/PokemonSunAndMoon''. An [=NPC=] mentions that Trial Captain Lana once used her signature Z-Move Hydro Vortex to get a Sudowoodo to move. Assuming that her Araquanid was the one using the move (which it is if you fight her), Hydro Vortex is based on Bubble Beam, meaning it has a base power of 120. Since this is super-effective on Sudowoodo, that goes up to 240 base power. And that's without STAB, with it the move would reach 360 base power. 120 is a very high power for a move. 240 is ''terrifying''. 360 is "[[ThisIsGonnaSuck welp, I'm screwed]]" levels. The Sudowoodo in question runs away in terror when it realises that the player can now use Hydro Vortex, and you can't really blame it.

* In ''VideoGame/DragonBallZBudokai 3'', battles in the story mode and arena mode net you more experience points for finishing a fight dramatically. A signature energy blast move is good. A 30+ hit rush (possibly capped with a signature energy blast) is even better. A signature super move visible from space - which the game will never neglect to show you - is best of all. But being a Franchise/DragonBall game, if you're not finishing fights like this anyway, you're not playing it right. For added effect, using an energy blast to finish things off will crack your opponent's HUD, while the super move will cause the thing to explode.

* ''VideoGame/JakAndDaxter'' didn't qualify until ''VideoGame/JakIIRenegade'', in which Jak got a SuperpoweredEvilSide possessing ''two'' kill-everything-on-the-screen attacks, as well as flickers of [[RuleOfCool cool]] purple lightning that followed his attacks. Then he got a gun capable of firing a lightning orb that blows up every hovercar on the screen. Then ''VideoGame/Jak3Wastelander'' handed him an ''upgrade'' to this gun which burns through at least half of your ammo in one shot...a shot which is so large ''it gets its own mushroom cloud''. As well as a variant form of his yellow gun which fires an AttackDrone that [[MoreDakka spams out ammo so fast it resembles a small but deadly rainstorm]]. Someone's really got to explain the concept of 'less than total destruction' to him. Ditto with [[AristocratsAreEvil Baron Praxis]], who intends to stop the Metal Heads with [[spoiler:''a bomb that can blow up the universe! All of it! That's less like "overkill" and more like "omnikill"!'']]

** And then, somehow, the Plumber got his hands on some RYNO V plans, because by the time of Into the Nexus, he has created the RYNO VII, which is like the RYNO V, but with more missiles and bullets, a sleek purple and black trim, and the added bonus of playing Night on Bald Mountain, the perennial music of complete DOOM.
* In ''VideoGame/{{Postal}} 2'' after killing or crippling people, you can choose to do some of the most sadistic things to them such as chopping them to pieces with a machete, setting them on fire, smashing their heads with a sledgehammer, blow them to pieces with a rocket launcher, break every bone in their body with a blunt object, etc.

** This is also the game that, with the gore settings all the way up, things explode in a shower of blood and bones when you kill them with a critical hit. This also works when killed by Instant Death spells - Implosion and Destruction actually look like they are ripping people inside out when they go off. Implosion is Area of Effect, so if it hits few creatures, the result is usually a fountain of blood and bones.

** ''VideoGame/ResidentEvil5'''s ultimate unlockable shotgun Hydra has ''three'' barrels side-by-side. Sheva has to wield it two-handed, but Chris and Wesker are so ridiculously ripped that they simply widen their stance and fire it with one hand at arms length. It has enough knockback potential to put any standard foe on its ass and does damage on par with a standard rifle at long-range, despite being...y'know...a {{sho|rtRangeShotgun}}tgun.

* In the ''VideoGame/MegaManZero'' series' GrandFinale, [[BigBad Dr. Weil]] [[spoiler:fuses to the [[KillSat Ragnarok satellite]] while it was [[ColonyDrop plummeting to the ground]], to fight [[TheHero Zero]] as the FinalBoss]]. If Weil wasn't killed by Zero, [[spoiler:then the satellite burning up in the atmosphere's re-entry]] should, right? ''RIGHT''? [[spoiler:Until ''VideoGame/MegaManZX'' rolled around, that is]]...

'''Liara:''' I dunno.. are you SURE you got them all?\\

** Two of your primary sniper teammates - Garrus and Thane - have this listed as their preferred way to take down krogan. Most of Thane's elimination techniques boil down to NeckSnap; with krogan he has to re-enact the boxing scene in ''Film/SherlockHolmes2009'' with added violence to deal with the secondary nervous system and so on (with alternate option: "Bomb"). Garrus, meanwhile, preferred to use DeathByIrony - shooting a gunrunner with a smuggled weapon, hurling dangerous drugs into the eyes of a drug smuggler - with the exception of one person, almost certainly krogan, who required being shot ''everywhere'' and third-degree burns.

* With a sadistic RandomNumberGod controlling everything from behind the scenes, you'll see a lot of Overkill in ''Franchise/FireEmblem''. So you hacked away at that boss's HP, leaving them with exactly 1 HP left? Well, the next unit to attack, which if it would crit (despite having a mere 1% chance to do so) would kill the boss from full HP... promptly will crit. Of course, if your plan is to leave the Boss with a minor bit of HP, so a weaker unit could kill it, the second attack of whatever unit you had sent into the fight to weaken said boss, also will be a crit, killing the boss immediately. Or when your unit did their first attack, leaving the enemy with a minor bit of HP, then they take the enemy's counterattack... that's when the Crit will come. Of course, it all works in reverse. The enemy won't kill your unit practically. They'll crit and overkill you.

** Along the same vein are the mastery skills from ''Path of Radiance'' and especially ''Radiant Dawn''. In the former, you have to use up a lot of skill capacity points just to learn them and you only get 4 opportunities per game, but the masteries that inflict damage cut through enemies swiftly whenever they kick in. But lordy, ''Radiant Dawn'' is a whole other beast: all units that promote to tier 3 (and Laguz that use a Satori Sign) get a free mastery skill, and they are ALL made of Overkill. Only one or two of them ''don't'' inflict 3-5x more damage, and some have a side effect (put enemy to sleep, etc.) that you're not liable to take advantage of because your hapless victims will usually become DeaderThanDead first.
*** Luna (in ''Dawn'') triples the user's Strength, then negates the foe's Defense, then usually crushes its' victim in one stroke. More or less, there's not a unit in the game that can survive that. ''[[ButWaitTheresMore But!]]'' If that's just not Overkill enough for you, consider the Black Knight's [[UpToEleven obscene]] mastery, Eclipse. Same effect, but 5x Strength instead. Based on the Knight's stats, he has a fixed 40% chance to inflict 208 damage. The final boss is 88 HP short of that. Ye gods. [[spoiler:Fortunately, when it comes time to duel the Knight in the final chapter, equipping Nihil shuts down Eclipse (and any other enemy mastery) altogether.]]
*** Trueblades' mastery skill, Astra, allows them to make five attacks instead of one. And with their high Speed, they're very likely to double attack. Give them a Brave Sword and the Adept skill (which causes a unit to attack twice instead of once if it activates), and it would be theoretically possible for them to attack forty times in one battle. And then you add in their high chance of getting a critical hit...
** A "Ruin Sage Morgan" (skill build for Morgan as Aversa's son where he's a Dark-wielding Sage equipped with a forged Ruin Tome)-- a theorized character in ''VideoGame/FireEmblemAwakening''... embodies this trope: 75 ATK (Magic) with 100% chance of activating vengeance, which can depend on his HP, raise that to 114... and he's got a 100% chance to critical. 342 Damage is quite painful in a game where the maximum HP is 80.

* In ''VideoGame/Persona3'' and ''VideoGame/Persona4'', if one of your characters uses a normal attack and lands a critical, they usually strike the enemy so hard or so many times, he not only gets massive damage but also is knocked down, in ''Persona 4'' for more than one round. Kanji is probably one of the best examples - his critical attack consists of throwing his chair/board/shield at the enemy, kicking him, and punching down to the ground. [[DefrostingIceQueen Mitsuru]] is also similar, she strikes an enemy vertically, launches a barrage of swift strikes, and curb-stomps him with boots on high heels. No wonder everyone is afraid of those two characters.
** The bonus bosses from both of those games like to indulge in overkill, too. If you attempt to, in any way, null any of their attacks, and also after a certain number of turns regardless, they will cast a powered-up Medigolaon which does 9,999 to the whole party. Now consider the fact that your HP is capped at 999...
** ''Persona 4'' has a type of Shadow known as a rare Shadow. In the Golden edition of the game, the rare Shadows in the dungeon Magatsu Inaba have an odd quirk - they have very low defences and absurdly high HP, resulting in you doing around 1000-3000 damage to them per hit. However, should you do the right setup, it's very possible to get over ''10,000'' hit points worth of damage on them due to their low defences. It's possible to do enough damage to take out both forms of the final boss with one hit. (The best setup for this is to use the Persona Satan, which gets the spell "Black Viper". This is the only attack in the highest damage category and is one of the few attacks that can actually hit the rare Shadows. Use Mind Charge for 3x damage on your next magic attack, and Tarukaja/Matarukaja to buff your attack stat, then use Black Viper for utterly obscene damage. Black Viper hits every enemy at once, so it's possible to do upwards of ''30,000'' damage total with this strategy.)

** The {{Final Boss}}es of the aforementioned Persona 4 and 5 games are also scripted to [[CutscenePowerToTheMax do this against you once you win the fight,]] while your characters hold on out of [[{{Determinator}} sheer willpower]] and/or ThePowerOfFriendship. [[spoiler:Izanami]] hits the main character over and over with ''Oho Ikazuchi'', non-elemental lightning that deals 999 damage, while [[spoiler:Yaldabaoth]] unleashes a [[OneHitKill battle-ending]] ''Rays of Control'' on the whole party. As for Persona 3, this is done by the PostFinalBoss instead. Their one and only attack is overkill embodied: a single droplet of energy that explodes when it hits the floor, hitting the main character for 9999 with literal ''Death'', done over and over. Fitting since the enemy is [[spoiler:Death herself.]] Just as a reminder, HP in all Persona games is capped at 999 for the player.

* ''VideoGame/AssassinsCreedBrotherhood'' isn't quite as over-the-top as many examples on this page, but one move has to stand out - stabbing a guard through the underside of the head, then firing the Hidden Gun at point-blank. The former would be a fatal wound in RealLife, and remember that the latter can punch through [[HeavilyArmoredMook Brute plate]] for a OneHitKill even at maximum effective range. At point-blank, one wonders why the head doesn't [[YourHeadAsplode explode]] or get sent flying.

* The ''Franchise/KingdomHearts'' games are known for absurdly difficult bonus bosses, but the Unknown in ''VideoGame/KingdomHeartsBirthBySleep'' takes the fucking cake. Virtually every attack he's got will reduce you to 1 HP regardless of level, which includes each individual hit from his overly long combos. Get hit with a full combo, and you'll be stunned, aka, deader than dead. Many of his own attacks consist of the most powerful deck commands in the game [[UpToEleven cranked up to eleven]], and to make matters worse, if you do manage to land a good combo on him...he'll just [[JustForFun/TimeLord reverse time]] and proceed to [[TheComputerIsACheatingBastard school you]]. There's Overkill, and then there's the Unknown.

* In ''[[VideoGame/ModernWarfare Call of Duty 4]]'''s Death from Above there is nothing more satisfying than using the 105mm to kill a single enemy soldier just because you have the time.
** Strangely enough, a reflection of RealLife. You can find several videos of AC130 missions on youtube; in at least one of them, the gunship is shooting at a lone infantryman who keeps evading the smaller shots by zigzagging around (he only succeeds because the time-to-target is several seconds). Then the gunner gets bored and/or irritated enough to fire the big gun...

* ''VideoGame/TheLastRemnant'' has a special combat effect just for that called, guess what, Overkill. It requires someone to be hit by an enemy with about twice as much damage as the defender's HP. While hard to perform on bosses and players, normal creeps often succumb to this. Overkills usually are so powerful, not only the entire Union dies (Unions share HP - if one person gets hit for 3k damage, entire group is as well), they are blown away like a rag-doll or disintegrated if it was a spell.

---> '''Festus''': ''"Do what I do. Walk up to your target, introduce yourself, melt their skin off, and then run like the wind. Works every time."''

** When your "Wanted" rating gets high enough, whether from a gang or from the police, they send out the big guns, possibly for just one man. These "big guns" can include genetically-engineered supermen, a FlechetteStorm of grenades, a girl who can FlashStep while DualWielding Uzis... and a tank.
** In Saints Row 2, Mr. Sunshine, TheDragon to the General of the Sons of Samedi, seems to take a lot of bullets before dying--and even gets up after the first salvo. You wind up decapitating him and throwing his head on a conveyor belt leading to a furnace to make absolutely sure.

** Some of the weapons you can get tend to qualify for this as well... employing a rocket launcher against a single person or even a car, calling an airstrike against someone, deploying a drone to fire a missile at one person... overkill is just another day in the office in Stilwater.

** Downloadable character Krieg the Psycho has a skill called 'Bloodsplosion,' which causes enemies to explode when killed...and enemies killed by that Bloodsplosion add overkill damage to ''their'' explosion. And so on, and so on, and so on. It only stops when there are no more enemies in range of an explosion. It's possible to string a long chain of these explosions sufficient to wipe out any boss that makes the mistake of summoning swarming enemies.

* In ''VideoGame/CityOfHeroes'', if you fail the "burning building" zone event, the building explodes, killing you. It was supposed to deal three ticks of 1000 points of damage, just enough to defeat the strongest characters -- but the person designing the explosion accidentally specified it as "1000% damage", meaning 10 times your maximum hitpoints. They left the error in because, well, it got the job done.

* Modern combat RTS ''VideoGame/ActOfWar: Direct Action'' has each faction equipped with a superweapon and counter-superweapon. International terrorist ring The Consortium's superweapon houses 3 shots per structure (and you can build multiple structures), making it alarmingly easy to simply inundate a base with superweapon attacks faster than the enemy can counter them. In addition, the Consortium superweapon is a satellite nudged out of orbit onto the target...but first, coated in e. bola. Needless to say, the strategy of "launching more satellites than you have Patriot missiles" tends to warrant some overcommitment of resources, just to be on the safe side.

** KillItWithFire taken to the extreme: Given the structure of its evolution line, it's possible to produce a Level 1 Scizor (4x damage from Fire) specifically for link battles. You also get the same effect from breeding out a Level 1 Paras - which also has much lower defensive stats and has an ability which can increase its vulnerability to fire. Toasty!
** Take a Lv. 100 Heatran (highest Special Attack of all Fire-types bar Reshiram and Mega Evolutions), give it Choice Specs (boosts Special moves), boost its natural Special Attack all the way up, change the weather to sunny, activate Heatran's Flash Fire, and attack the above Paras with Overheat, the strongest Fire-type attack Heatran can learn. Put that through a damage calculator, and the damage reaches the millions - 6255207 damage. That would essentially erase that Paras from existence.

** The maximum possible amount of damage dealt in one turn by single pokemon is believed to be this: A Shuckle with 614 attack stat from Power Trick, two Helping Hands, two Flower Gifts, skill-swapped Huge Power ability, at +6 Atk, with x2 boost from Metronome item, using Me First boosted Rollout after a Defence Curl, with Same-Type-Attack-Bonus, on a 4x Super-Effective Critical-Hit, against any pokemon with a defense stat of 1 and 4x weakness to Rock. According to [[http://www.smogon.com/bw/articles/bw_complete_damage_formula this]] damage calculation formula, the damage dealt on the 5th turn (when Rollout and Metronome reach their maximum power) is 721,898,952. Over seven hundred million. One imagines that if a pokemon were to be hit with an attack of this magnitude, rather than merely fainting, both the target pokemon and everything else in a large radius would be reduced to nothing more than an expanding cloud of ash and a smoking crater. As they say, "You don't fuckle with Shuckle."
*** To give you an idea of how ridiculously overkill this all is, the highest amount of HitPoints a Pokemon can have is '''1428''', and even in that particular case, it's only for three turns.[[note]] Which is a Dynamaxed Blissey with 31 HP [=IVs=] and maximum EV investment in HP.[[/note]]

** In a strange non-damaging example of this trope, there are early-game trainers of the Rich Boy and Lady trainer classes in ''VideoGame/PokemonRubyAndSapphire'' and ''Pokémon Emerald''. They use [[ComMons Zigzagoon]] at level 7. The overkill is that, instead of using common cheap healing items like a normal Trainer would do to heal their Pokemon, they use the late-game Full Restores to do the job. For comparison: A potion costs 300, heals 20 HP, and is readily available in any store. Full Restores cost 3000, restore all HP as well as remove any status problems, and are only available super late game. Keep in mind they're using them on ComMons that are probably lower level than your starter by that point. Pretty over[[IncrediblyLamePun heal]], isn't it?

** In terms of moves, Dracovish's Fishious Rend can be one of these. The move's base power if the user moves first is 170 (original base power of 85 that doubles if the user ges first). Factoring in STAB, a Choice Band, Strong Jaw, rain, and double weakness against Water, (170 x 1.5 x 1.5 x 1.5 x 1.5 x 4) the move's total power comes out to '''''3442.''''' For comparison, a super-effective STAB Z-Move based on a 140+ power move comes out to 1200 base power, and the highest power Max Moves are 150 base power. Anything hit under optimal conditions with Fishious Rend would be snapped like a twig under Dracovish's jaws.
* The ''VideoGame/{{Worms}}'' series. Your enemy is down to the last worm, and standing on a ledge just begging to be [[CherryTapping poked?]] Nah... still got that HolyHandGrenade!

* In ''VideoGame/NoMoreHeroes'', after hitting a {{mook}} enough times, Travis can perform a special move that decapitates the {{mook}}, showering Travis in blood and coins. This becomes practical later in the game - said special move can also decapitate/split in half other mooks nearby, resulting in multiple showers of blood and coins.

* In the HopelessBossFight at the beginning of ''VideoGame/PaperMario'', Bowser whittles Mario down to almost no HP... then hits him with an attack that does ''10'' damage, which is pretty high-powered for this game.

* The hip-hop-themed fighting game ''[[VideoGame/DefJamSeries Def Jam: Fight For NY]]'' actually ''required'' you use stronger means than a normal punch to finish your opponent and end the match, usually in the form of high-powered combos, ''smashing your opponent into an element of the stage'', hitting them with a weapon, or the oft over-the-top special moves. And that's not counting the stage where you can push them in front of a passing subway train...

* ''VideoGame/AceCombat6FiresOfLiberation'' requires you to fly your plane down the barrel of the Chandelier cruise missile launcher. Yes, a launcher with missiles so big you can fly a plane down its barrel. If a missile is launched with the plane still inside, well, "OneHitKill" is putting it... lightly. On the player's side, it's easy to single out a single target for all four or six special missiles, pop off the heaters and lose a few gun rounds as well. Or feed a single, isolated ground target a FAEB/LSWM/MPBM, all weapons meant for wide-area devastation.

*** Marisa in particular has a combination technique, where Alice and Patchouli cast buffs on her before she does a ''very'' good impression of Thrugelmir's ''Blade that Cleaves Continents'' that even '''shreds''' the spectator stands. Thankfully for the audience, spellcards only inflict all non-lethal damage...

** Inverted in Cirno and Letty's combination strike. [[TheDitz Cirno]] moves to blast the ball with her [[AwesomeButImpractical Icicle Fall (Easy)]] spellcard, apparently forgetting that it can't hit anything directly in front of her... like, say, an oncoming soccer ball. The ball proceeds to hit her in the face - not once, but ''fifty bajillion times'', making it a rare case of overkill from the target to the attacker. Though to be fair, it's still a good hit and the ball can rebound and score a goal.

* The entire shtick of ''VideoGame/KillItWithFire''. Your task? Exterminate creepy, but harmless [[SpidersAreScary spiders]] infesting normal apartments. Your tools? [[MoreDakka Guns]], [[StuffBlowingUp explosives]], and of course, [[KillItWithFire fire]].

* In ''[[VideoGame/{{Hitman2016}} Hitman (2016)]]'', the final main story mission in Hokkaido features one target, [[spoiler: Erich Soders]], who is on the operating table awaiting a heart transplant. Most of the opportunities involve killing the target on the table, but one involves destroying the donor heart and leaving the target to die unable to get a new donor heart instead. Two challenges involve both destroying the heart and killing the target on the table. The one for killing the target on the table first [[ExactlyWhatItSaysOnTheTin is even called "Overkill;"]] the one for destroying the heart first is a LampshadeHanging called "I Think [[spoiler: He's]] Dead Now."

* [[UpToEleven Taken to ridiculous levels]] in Mugen Souls. Literally EVERY special move counts as this. Let's see, we have: Launching your foes into the sky on a giant beam of light, piercing (and of course destroying) multiple planets in the process and subsequently destroying the sun, [[spoiler:what makes this particular attack even more hilarious is the 'OOPS, I DIDN'T MEAN TO GO THAT FAR' in the end]], slicing planets with a giant sword, opening black holes, summoning giant demons of death, etc, etc. But let's not forget your own special attack - the Peon Ball. Basically a giant ball of energy, which gets bigger (and more powerful) as you get more Peons from fights... let's see... someone made a video of it with size: Galaxy. Yes you're literally able to throw an energy ball the size of a galaxy on your opponent. Also Overkill is literally the only thing you do in late game. You can upgrade your level-limit to 9999, also every item again being able to being upgraded more or less infinite times, lets just say that one-hitting bosses - with your normal attack... isn't all that special once you reach a certain point in the game. As for normal foes... well you do the math.

* ''Film/TheMatrix: Path of Neo'' allows you to pummel an enemy, lift him up into the air to continue the beating, leap up and smash him into the ceiling, fling him to the floor, and stomp on his throat with both feet.

* In ''VideoGame/ResidentEvil3Nemesis'', how does the titular Nemesis show the audience that [[ItCanThink He Can Think]] ''and'' that he's not one to be messed with? Rather than simply smash through the front door of the police station to chase Jill, the already practically unstoppable killing machine decides it would be better to go and arm himself. ''With a missile launcher''.
* ''VideoGame/ResidentEvil5'''s Hydra: The game's ultimate unlockable shotgun has ''three'' barrels side-by-side. Sheva has to wield it two-handed, but Chris and Wesker are so ridiculously ripped that they simply widen their stance and fire it with one hand at arms length. It has enough knockback potential to put any standard foe on its ass and does damage on par with a standard rifle at long-range, despite being...y'know...a {{sho|rtRangeShotgun}}tgun.
** How [[spoiler:Albert Wesker]] is killed. Hit by ''two'' rockets, which explode him into a lake of molten lava. Justified, because his mutations make him immune to most conventional weapons at this point.
* ''VideoGame/MaxPayne'' has a rather different concept of this. Rather than you keep shooting mooks that are already dead (which you can), Max shoots a boss after he is clearly dead. ''Over and over again''. He had to have emptied at least one magazine (which given his weapon, a Beretta 92FS, means at least fifteen rounds) into him.
** Given that the boss in question (Jack Lupino) is really, ''really'' strung out on [[PsychoSerum a drug]] that's known for rendering people oblivious to even the most crippling injuries, it wasn't an entirely unreasonable precaution.

** The Killer Suits in the stage "The Deep Six" empty their mags into a guy at the beginning in an effort to erase all evidence of Project Valhalla. One of them reloads and puts a final round into him before the other guy tells him "I think he's dead already."
** A mod to the game lets you wield a handheld minigun.
** In ''3'' there's a slow-mo killcam when you kill the last enemy in a setpiece. You can keep firing to riddle the body with bullets as this happens.

** [[BrainInAJar Mother Brain]] ends up on the wrong end of another such smackdown in ''VideoGame/SuperMetroid,'' when she murders the infant metroid from ''VideoGame/MetroidIIReturnOfSamus''/''VideoGame/MetroidSamusReturns'' and earns herself a Hyper Beam-fueled RoaringRampageOfRevenge from the creature's [[MamaBear human adoptive "mother."]] The final shot decapitates Mother Brain, exploding her cybernetic combat body; her severed head turns to gray powder as it hits the floor.
** ''VideoGame/Metroid1''/''VideoGame/MetroidZeroMission'' concluded with Mother Brain's self-destruct timer blowing up the Pirate base, but leaving the surface intact. But since that failed, in ''Super Metroid'' the self-destruct causes a massive, Zebes-Shattering Kaboom.

--> '''MC''': My coach used to say that ''overkill'' is something only the other guy complains about. But he was an old Marine, so that probably had something to do with it.

* ''Videogame/NuclearThrone'': The Hyper Crystal boss deals 200 contact damage, where the maximum health you'll get never exceeds 25. Appariently, touching the Hyper Crystal would be like having said touching limb stretched infinitley into the next dimension instantly acording to the developer.
