History YouHaveOutlivedYourUsefulness / VideoGames

* In ''VideoGame/{{Bomberman}} 64'', after you [[spoiler:beat Altair with 100 gold cards, Sirius]] does this to you.

** Also, one of the missions has Hudson and Weaver going to secure a scientist, Clarke, [[spoiler:because Dragovich is cutting loose ends and they want to get to him before Dragovich does. They do get to him first but unfortunately Clarke is killed during the escape.]]

* In ''VideoGame/FireEmblemThreeHouses'', [[spoiler:Edelgard, aka the Flame Emperor, despises "those who slither in the dark" [[TeethClenchedTeamwork despite being allied with them]], viewing their cooperation as a necessary evil to succeed in her campaign against the Church of Seiros. She fully intends to turn on them once she's achieved that goal, and in her route's ending she does just that, ultimately wiping them out entirely. As the group in question are thoroughly despicable {{Hate Sink}}s to a man in contrast to the WellIntentionedExtremist Edelgard, this is a rare heroic -- or at the very least {{antihero}}ic -- example.]]

* This, crossed with YouHaveFailedMe, starts the plot of the NES ''VideoGame/{{Strider}}'' game - Strider Hiryu is informed that Strider Kain was captured by the enemy. Just when you think you're being sent to rescue him... "As his identity is now known, rescue is not an option. Kill him! That is all." Needless to say, Hiryu's ''not'' about to kill a comrade on some computer screen's say-so, and heads out to find more information...

* In ''VideoGame/ShinSakuraWars'', [[spoiler:Yasha seriously wounds Anastasia Palma once the latter gives her the Amamiya Kunisada so that President G/Genan Sotetsu can further his plans at the end of chapter 6]].

* ''VideoGame/DevilMayCry 3''; BigBad Vergil stabs Arkham through the midsection after it became apparent that he was useless to him. [[spoiler:Arkham may have brought this on purpose, in order to later convince Lady to hunt Vergil and complete his plan for world domination. Dialogue and AlternateCharacterInterpretation suggests it's also quite possible that Vergil killed Arkham out of disgust; Arkham is an active worshiper of Evil and murdered his own wife, while Vergil is simply power-hungry and seeks to regain what he sees as his own heritage.]].
** [[spoiler:Arkham survived Vergil's attempt to kill him. It's actually Lady who finishes him off, with a bullet to the head in revenge for killing her mother, just before Dante and Vergil's final battle]].

* ''Franchise/KingdomHearts''

* In ''VideoGame/PerfectDark'', after the first two version of their plan, which attempted to take advantage of Trent Easton's political connections, fail, Mr. Blonde reveals his alien nature and dispatches Easton in a combination of YouHaveFailedMe and this trope. When the last, least subtle plan is thwarted as well, the Skedar imprison their other ally, [[CorruptCorporateExecutive Cassandra DeVries]], for the same reasons.
* In ''VideoGame/PerfectDarkZero'', after Chandra brings the Graal to Zhang Li, [[DevourTheDragon he sacrifices her for her life force]].

* The Snatcher of ''VideoGame/AHatInTime'' employs this method with unwilling contractors that finish his dirty work. When he's first encountered, he explains how his last contractor got himself killed (his head popped off), but later reveals that the contractor's head "popped off the moment he stopped be useful to [the Snatcher]". He tries the same thing to Hat Kid when she finishes all of his contracts.

* In any game where you can [[VideoGameCrueltyPotential kill allies and receive any upgrades they might have]] often prompts [[WhatTheHellPlayer many players to use this trope themselves]]. Take, for example, the original ''VideoGame/HalfLife1''. Guards can help you out by being a second gun and shooting enemies... but once you come to an inevitable airduct where they can't follow, well... it's a shame to just leave that ammo behind...

** He does (or threatens to) something similar several times during the game. Considering [[NietzscheWannabe he deems human life as a waste of natural resources]] or, at best, material [[ForScience for experiments]], this is hardly surprising.

*** Although it's also a case of Shepard refusing to accept anything other than wiping out the Reapers [[spoiler:until the end where s/he learns it's not quite that simple.]] Persumably if Shepard were on board with his plan, they'd have Kai Leng's job.

** In the OmegaEnding for the Japanese version of ''VideoGame/AceCombat3Electrosphere'', [[spoiler: Simon Orestes Cohen reveals that the whole game was a simulation, and that the PlayerCharacter, Nemo, is an ArtificialIntelligence that he created to kill [[BrainUpload Abyssal Dision]]. And since the simulation showed that no matter what happens, Nemo will kill Dision, Simon decides to purge the Nemo in the simulation, since the program had served its purpose and thus he no longer needed it, and [[MindWipe creates a fresh copy]] of the [=AI=], that he intends to unleash upon the world to eliminate Dision. However, his intent to purge the Simulation Nemo wasn't so much cruelty as it was [[ PragmaticVillainy simple practicality]]; in order for Simon's plan to work, Nemo would have to reach the final confrontation with Dision ''on its own'' without prior knowledge of the war, so that the events would play out as the simulations predicted.]]

** In ''VideoGame/WarcraftII: Tides of Darkness'' ' Orc ending, Ner'Zhul and the player go through a portal and leave the rest of the Horde on Draenor, which is about to be destroyed.

* In ''VideoGame/AceCombat7SkiesUnknown'', Rosa Cossette D’Elise, the princess of Erusea, had been manipulated by young Erusean officers called the Radicals to declare war on Osea under the belief that she was protecting her country from what she perceived as Osean Imperialism. During the war, the Radicals used her as a propaganda girl to bolster troop moral, and rally support for Erusea against Osea. [[spoiler: However, when Farbanti had fallen under Osea control, and Rosa fled in her personal plane, the Radicals had tried to kill her by shooting down her personal aircraft, as she was no longer of any use to them, and because their drone army was nearing completion. After she barely survived, Rosa was taken in by the Oseans to help bring about the end of the war.]]

* Said word-for-word in ''VideoGame/CommandAndConquerRedAlert3'', by [[spoiler:Soviet Premier Cherdenko]]. You proceed to annihilate the guy after already kicking the backside of two other significant threats.

** Sarah herself gives this treatment to two entire ''armies'' in ''Starcraft: Brood War'', including, ironically, Mengsk himself.

* ''VideoGame/NintendoWars'': Advance Wars: Days of Ruin'': After the {{b|loodKnight}}arbarian known as The Beast is defeated in Mission 10, the game's BigBad [[LeftForDead leaves him to die]] as the experimental drugs he was injected with ravage his psyche.

*** But it's all good, because then Tabuu gives the boot to Ganondorf so that he can join the heroes in time for the final battle.

*** The Werewolf path in the ''Bloodmoon'' expansion ends precisely the same as the other path: [[spoiler: you facing off against an avatar of Hircine]] in battle, regardless of your previous service to the Daedra.

* In ''VideoGame/KingdomHearts'': Following [[spoiler:Sora's HeroicSacrifice]], the game's BigBad, [[spoiler:Ansem, appears out of nowhere and is about to pull this one on Kairi, but Riku holds him back long enough to let her escape with the others]].
** In ''VideoGame/KingdomHeartsII'' after Naminé finishes restoring Sora's memories at the end of the prologue, [=DiZ=] orders Riku to destroy her, at least partially because of his [[FantasticRacism prejudice against Nobodies]]; Riku, however, has no intention of doing so, both because of Naminé helping him and Sora during the events of ''VideoGame/KingdomHeartsChainofMemories'' and because he's ''not'' happy to discover that [=DiZ=] only helped restore Sora for the sake of petty revenge against Organization XIII, and instead lets her go. During the game's final act, Organization XIII also declares that, with their Kingdom Hearts completed, they have no further need for Sora, and try to dispose of him.

** In ''VideoGame/KingdomHeartsDreamDropDistance'', [[spoiler: Riku finds himself in the exact same position of Xehanort's plans as Aqua was well over a decade ago, given that he's now [[IncorruptiblePurePureness immune to Xehanort's attempts to corrupt him with darkness.]] And, just like Aqua, he ends up giving Xehanort a [[{{AwesomeBosses/KINGDOMHEARTS}} much-deserved ass-kicking]] in the climax.]]
