History ThereIsNoKillLikeOverkill / VideoGames

* Modern combat RTS ''Act of War: 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, [[ItGotWorse 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.

* In ''3DDotGameHeroes'', 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.
* In ''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.

**** Screw that. According to Bulbapedia, it's possible to deal about 50% MORE. "Although the circumstances would be nearly impossible, using Rollout, a level 100 Shuckle can potentially deal the most damage in one single attack through the use of numerous stat boosters, by using Helping Hand, Metronome held item, Power Trick, a Skill Swap to Pure Power or Huge Power, and the Defense Curl/Rollout combo. Also, Shuckle's partner must have the ability Flower Gift and the weather must be sunny. On the 5th impact of Rollout, if used against a level 1 Ledyba that has been hit with negative Defense modifiers (such as Screech), it can deal 213,896,052 damage with a critical hit.". '''19 445 095.6''' KOs. Also, when this tropes went to copy this, he saw something new... "Actually the above isn't the most damage. Via calculations if the Shuckle is at level 100 and it has a defense enhancing nature with 31 IVs and 252 EVs in Defense and the Ledyba has a Defense hindering nature, after using all those powerup moves, without using Screech at all, and the Ledbya would still have a defense of 5, with a critical hit Rollout on the 5th turn, it can deal up to 821,360,590,800. But by sending Ledyba's defense to 1, almost 0 landing a critical hit on a level 1 Ledyba with any nature since 6 or 5/4 is approximately 1 as fractions don't exist in stats, on the 5th turn of Rollout, it can lash out 4,106,802,954,000 damage. 4 trillion 106 billion 802 million 954 thousand damage or 4 trillion 1 hundred 6 billion 8 hundred 2 million 9 hundred 54 thousand damage to make it easier to read this way. Almost an infinite amount of damage. This can be calculated by taking 2 of 100 and then using the forumla 5/2 * 614 which is Shuckle's highest defense stat at a Relaxed, Lax, Bold, or Impish nature with 31 Ivs and 252 Evs in the stat, +614/2 which gives 50% of 614, 307 *2*960*480^2/50) since /1 is pointless +2) *1.5 for STAB *4*2 for critical hit. The problem is then worked out from there until all the stuff that needs to be added and multiplied is completed. "... [[{{Cap}} 4,106,802,954,000]][[hottip:* :(Levels use 8-bit unsigned integer, which ranges from 0 to 255, this is why when you Rare Candy Lv. 255 Mon in Gen I or Gen II, it drops to Lv. 0 - it overflows. Until Gen III, the Pokémon were also stored in this, so there was only 4 glitch Pokémon in Gen II. However, it was upgraded to 16-bit unsigned integer, allowing for 65536 Pokémon, which is squared 256. To be able to get to such (ie. the damage Shuckle did) number, you would need a 64-bit unsigned integer which ranges from 0 to 18,446,744,073,709,551,615 (18,446,744,073,709,551,616 numbers, which is, of course, square of 4,294,967,295, which itself is square of 65,536). That number is so freaking big that it's 4 491 752.9 times higher than the damage Shuckle can do, which itself is incredibly high)]] damage. That's almost [[OhCrap 19 200]] times more than the previous thing. This damage is enough to KO Ledyba about 373345723000 times. If humans were Ledyba... Our population is about 7 000 000 000. With the damage above... god, Rollout would [[HighOctaneNightmareFuel kill our entire population about '''53''' times]]

* ''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 92-FS, means at least fifteen rounds) into him.

*** Granted, Ridley did kill Samus' parents in front of her; and he's also been revived countless times. She might just have been making sure he wouldn't return. ([[IGotBetter He usually does anyway.]])

*** The RYNO V is notable for having an inbuilt speaker system that plays [[StandardSnippet the 1812 Overture]] whenever you fire it. Because, [[WhatDoYouMeanItsNotAwesome you know]], when you've got that much firepower, why the hell not?

* In the ''{{Battlefield|Series}}'' series, using the tank's main gun or anti-tank weaponry on a soldier qualifies.

** The sheer amount of resources that the Reapers have poured into neutralizing Commander Shepard is simply awe-inspiring. Given that s/he's [[DidYouJustPunchOutCthulhu killed a few of them,]] [[{{Badass}} it's a bit justified.]]

*** Taken even further at the final confrontation in ''Mass Effect 3''. When Shepard leads a charge on foot on the teleporter that will take them 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, who continues to crawl 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.

* ''{{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.

*** In ''MortalKombat9'', the first of Quan Chi's fatalities involves ripping off your opponent's right leg and then hitting him with it so that he falls to the ground. Once in the ground, Quan Chi hits him in the head twice with his own leg and then [[YourHeadASplode it explodes in little fragments]]. And after that he ''keeps beating him to a pulp while the fatality assessment shows up and until you exit the match''. Who needs necromancy, eh Quan Chi?

*** Taken even further at the final confrontation in ''Mass Effect 3''. When Shepard leads a charge on foot on the teleporter that will take them to TheVeryDefinitelyFinalDungeon, Harbinger tries to shot Shepard with its massive WaveMotionGun to prevent that from happening. [[spoiler:It even hits, but still isn't enough to completely kill Shepard, who continues to crawl the final meters]].

* In ''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]]".

* In ''RuneFactory3'' you can continue to hit a dead enemy if they are knocked up. 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.

* The Final Strike from ''MegaManX: Command Mission'' 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 MegaMan finalizes and performs the Red Gaia Eraser (in ''Megaman Starforce 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 the ''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 ''MegaManZX'' rolled around, that is]]...

** 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 PvE fights.

* ''[[{{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.

** 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 17,000 damage. The highest HP character in the game[[hottip:* :except Unlimited Ragna]]. has 13,000 health(Tager), and will likely have only 2,000 left before you can initiate an Astral Heat.

* In ''VideoGame/TheGodfather'', after choking someone to death, Aldo seals the deal with a NeckSnap. You can never be too sure, right?

* In the ''Morrowind'' The player can become this using the easily trainable alchemy skill, which allows you to brew a potion to increase your intelligence. Intelligence being the governing attribute of the alchemy skill. Thus this allows you brew another, more powerful potion to increase your intelligence. Do this for a while and then brew for example "Fortify Attack" and "Fortify Strength". This allows you to kill the second form of [[FinalBoss Dagoth-Ur]] in one hit, even though he is scripted to be invincible.
** "Fortify Speed" is an option as well, but it would require one to install a third party program that allows you to slow time in-game otherwise the character becomes too fast to control. It actually becomes too fast to calculate for the collision detection resulting in things like being able to run trough mountains.

* In ''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 reduces their base to a lifeless smoking crater.

** 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 nuklear 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.

** The UnrealTournament games are famous for several GameMods 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? That's for losers!

* 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? [[http://www.youtube.com/watch?v=5sIDUv4RtGg Just watch this]]. **Its sequel, ''Turok 2: Seeds of Evil'', actually managed to ''[[BeyondTheImpossible 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.

* Some TowerDefense games sum overkill damage for achievements. [[{{Gemcraft}} Gemcraft Labyrinth]] rewards you with EXP multipliers for large sums each battle.
