* ''StarWarsForceCommander'': After proving their loyalty in combat, [[http://starwars.wikia.com/wiki/Tyr_Taskeen Tyr Taskeen]] allows several imperials to join the Rebellion as trusted officers. This is common in the Star Wars universe; defectors are only executed if discovered before they actually defect. Their new superiors trust them after a heroic action or the revealing of top-secret information. [[http://starwars.wikia.com/wiki/Defection]]
* ''VideoGame/TombRaider2013'': When Whitman betrays Lara and co. by handing Sam back over to BigBad Mathias, the latter rewards him by tricking him into approaching Himiko's Stormguard as a distraction and then slipping by with Sam while he's being torn apart.
* In ''TabletopGame/{{Warhammer 40000}}: DawnOfWar: Dark Crusade'', during the Imperial Guard stronghold assault, the Guard's Fifth Company can be turned rogue and allied to the attackers' faction by killing their [[BadBoss Commissar]]. After the battle, if you were playing as the Space Marines, you see the Marines sending the survivors back to Segmentum Command, with a request to their superiors to not punish the Guardsmen because they followed their orders and fought with honor... except Fifth Company, who the Marines summarily execute for treason. Ironic, isn't it?
** Also occurs in vanilla ''Dawn of War's'' campaign. Said traitor [[spoiler: (Isiador)]] steals the MacGuffin from right under the other space marines' noses, only to have the BigBad immediately take the item for himself and leave the traitor and his marines to guard the rear. Meaning he has to face the ''very'' angry Force Commander[[spoiler:/former best friend]] he had just betrayed. Needless to say, he doesn't last long.
* The ''OperationFlashpoint'' expansion, Resistance, has an alternate ending (though it occurs after the 3rd mission) where you betray the Resistance to the Russians. Immediately afterwards, you and the remaining Resistance members who have been captured are taken to the General, who orders the prisoners execution. As they are being lined up, a officer asks about your character -- he orders that you be executed as well, because you are seen as 100% untrustworthy.
* In ''FireEmblem: [[VideoGame/FireEmblemTellius Path of Radiance]]'', the half-cowardly, half-ApatheticCitizens of a port town inform the Daein soldiers about which boat Ike and his company took. When they ask for their reward, they are told that it was their country's own princess in that company that they just sold out. Just as the realization and guilt really begin to sink in, the captain of the soldiers has the "dastards" taken away to be worked to the bone, a "fitting reward" for people who would sell out their own princess.
** In ''VideoGame/FireEmblemAwakening'', a man who Chrom knew well sold out Emmeryn (his sister) to the Plegians. He's slaughtered at the spot of the ambush.
* In ''VideoGame/PrinceOfPersiaTheSandsOfTime'', the Prince regrets that his father did not give the Vizier this treatment, as he betrays them almost immediately after betraying his former liege and joining them.
* There's an example in ''VideoGame/{{Fallout 3}}'' that crosses over with YouHaveOutlivedYourUsefulness. You're captured and interrogated by the BigBad. He demands the code to the purifier. If you actually give it to him, he shoots you. Game over.
** From the ''Point Lookout DLC'', a question from a BrainInAJar: What is the greatest thing man can acquire? Answer 1: Something that I'll give to you if you backstab your ghoul partner. Answer 2: Death. Said brain betrayed the ghoul back when they were still human, so genre savvy players will recognize that one insane (read: lobotomized) vault dweller versus a brain in a jar and a small army of robots with frickin lazer beams is very less likely to win than one insane vault dweller and one experienced robot scientist versus a brain in a jar and a small army of robots with frickin lazer beams. Hence the backstabbing.
** Also occurs in ''VideoGame/FalloutNewVegas'', though not with you. [[spoiler:Caesar's Legion was offered a deal by the town of Nipton: in exchange for a sum of caps, the mayor would round up NCR troops and Powder Gangers inside the town and trap them. The Legion captures everyone - including those who were helping - and plays a [[LotteryOfDoom game with them]].]] It helps that [[spoiler:Nipton was a WretchedHive and the mayor was an unscrupulous jerk]], though most people consider this their MoralEventHorizon, given the brutality of the Legion.
* In ''VideoGame/DragonQuestI'', when you confront the BigBad at the end, he offers to let you [[WeCanRuleTogether rule by his side]]. Say yes and it's GameOver.
* Subverted in ''VideoGame/{{Makai Toshi SaGa}}''. Byak-Ko decides to kill Mireille because [[YouHaveOutlivedYourUsefulness he has no more use for her]] after she betrays [[LaResistance the resistance]] and her sister Jeanne, but Jeanne [[TakingTheBullet takes the bullet]].
* At one point in the PC game ''VideoGame/SpycraftTheGreatGame'', the villains approach you with the offer of joining their organization. If you accept you're tasked with assassinating the President of the United States. Regardless of whether or not you do it you're then [[spoiler: killed by another assassin as payback for arresting his girlfriend earlier]].
* ''VideoGame/BloodStorm'' kicks off with the High Emperor getting assassinated, and all eight fighters are pointing fingers at each other. [[spoiler: If [[RebelliousPrincess Tempest]] wins, she accidentally lets slip that she released the BigBad and ordered her father's execution. She is promptly overrun by an angry mob and beheaded.]]
* In ''VideoGame/AdventureQuestWorlds'', [[spoiler:if you make the choice to betray and kill Artix during the finale of the Doomwood saga, Vordred "rewards" you by making you the very first of his new undead minions as he unleashes a ZombieApocalypse upon Lore]].
* Implied in ''VideoGame/GrandTheftAutoIV'', Playboy X and Dwayne are longtime friends. When Dwayne returns from prison a sullen man, eventually the two butt heads to the point where Niko needs to kill one to continue the plot. If the player kills Dwayne, Playboy calls him up and wires a large amount of money, but tells him that he has to try to kill Niko if they ever see each other again (They don't).
** A more likely explanation is that Playboy X doesn't want anyone else to know of his involvement in Dwayne's death, as it would be really fishy for him to not try to kill the murderer of his "best friend".
* In ''VampireTheMasqueradeBloodlines'', if you choose to [[spoiler:betray the Kindred and side with the [[ChineseVampire Kuei-Jin]], Ming-Xiao will reward you by chaining you to the Ankaran Sarcophagus and [[FateWorseThanDeath throwing it into the ocean]].]]
* In the Dark Brotherhood questline of ''VideoGame/TheElderScrollsVSkyrim'', [[spoiler:Commander Maro launches an attack on the Dark Brotherhood Sanctuary after Astrid arranges for you (the killer of his son) to be captured by him. The fact that she was the one who ordered the kill is definitely a factor in this.]]
* Wizard101 has a weird version of this trope when the player accidentally unleashes [[SealedEvilInACan Axenos]]. Axenos is genuinely thankful to the player and [[MercyKill his attempt to kill the player is meant as a true reward]] since it will spare the player [[FateWorseThanDeath from witnessing the horrors he plans to bring upon the spiral]].
* [[BigBad Maximilian]] does this to [[TheQuisling Prime Minister Borg]] in ''VideoGame/ValkyriaChronicles''. It comes across as mostly PragmaticVillainy, as Borg is almost comically treasonous and untrustworthy.
* A subversion of this takes place in the main campaign of ''FinalFantasyXIV''. The first battle with Ifrit is started with a cutscene wherein a pair of traitors who sided with the Amalj'aa end up having their [[BrainwashedAndCrazy souls scorched]] by the Primal. Unfortunately, this also includes all the survivors of the previous battle as well, except for your character. [[DownerEnding Soul scorching cannot be reversed, however, ]][[ShootTheShaggyDog forcing the Immortal Blades to kill both the traitors and their own soldiers.]]
* ''VideoGame/PlanescapeTorment'' has a meta-example in the Fourth Circle of Zerthimon: According to the passage, in the middle of a Githzerai uprising, a Githzerai named Vilquar voluntarily warns the illithids and feeds them as much intelligence as he can. They kill him the instant they feel their victory is assured.
* Averted by Gwyn in ''Videogame/DarkSouls''. After Seath the Scaleless betrayed his fellow Dragons, Gwyn rewarded Seath by making him a Duke. This did not sit well with Gwyn's bishop Havel the Rock, who hated Seath and the sorcery that Seath created.
