* ''VideoGame/{{Marathon}}'': Military discipline amongst the Pfhor must be very lax, as friendly fire-induced infighting os a staple of gameplay, made even more exploitable by a lack of ranged limitations, plus a number of [[MeleeATrois preexisting grudges]]. Inducing such brawls in the series is eased by the fact that most enemies fire slow-moving projectiles. This tactic is probably the only reason the game is even winnable on [[NintendoHard higher difficulty settings]].

* ''VideoGame/SekiroShadowsDieTwice '': Predominantly happens in the second and third phase of the game, most notably in Ashina Castle. You can lure some of the blue swordsmen against the invading Lone Shadow forces. Nothing more entertaining than to see a classic ninja vs samurai battle.

* ''VideoGame/{{Minecraft}}'': If any mob that fires a projectile hits another enemy, a fight to the death ensues. Creepers actually drop a special item if they're killed by skeletons. If the mob attacked is part of a group (i.e. piglins, pillagers, etc.), the whole group will gang up on the one struck them first. However, piglins and pillagers will never intentionally attack their own kind.

* ''VideoGame/MetroidPrime'': In the Phazon Mines, you shut down a force field separating some Space Pirates from a horde of Metroids. As long as you don't draw their attention, they'll kill each other for you, maybe leaving one Metroid behind. There are also a couple of rooms where there are Metroids in containment tanks in rooms with Space Pirates (often Stealth Pirates). Blow open the tank, and there's a chance they'll encounter and kill the Pirates first. (There's also a chance they'll find '''you''' first, however.)

* ''VideoGame/Left4Dead2'': The Bile Bomb mimics the effects of the Boomer's vomit. Splashing it on any zombie will cause a horde to swarm and attack the zombie(s) that have been hit by the Bile Bomb. Hitting the Tank with this earns you the [[JustForPun Septic Tank]] achievement and HilarityEnsues as you watch it being mobbed by its own kind. If you splash the bomb on two special infected, they will also duke it out to the death for more [[HilarityEnsues hilarity ensuing]]. Bile Bombs in VS mode is a major annoyance to the infected players since their screen gets covered in bile like they were vomited on by a Boomer and all the common infected will swarm the player and beat them to death. The hilarity stops ensuing if a Boomer vomits on someone, negating the effects of the bile bomb.

** ''VideoGame/FarCry6'': Weapons loaded with poison rounds have a chance to make your enemies turn against their comrades before they succumb to the damage-over-time effects.
