History Main / NoCasualtiesRun

** The Player Avatar of ''VideoGame/FireEmblemAwakening'' has this attitude by default. The loss of one unit is too many. Virion lampshades this when he wins a strategy game with heavy loses. If he were leading an actual army, the morale loss would have him quickly demoted.

EverybodyLives as a SelfImposedChallenge. This is where you try to make sure there are absolutely minimized, if any, casualties.

--> Just this once, nobody dies!

* Most ''Franchise/FireEmblem'' players follow this trope by default, since [[FinalDeath losing a unit often means they're gone for good]].
** Starting around VideoGame/FireEmblemElibe and carrying on into the likes of VideoGame/FireEmblemTellius, the enemies actually try to focus not just on their victory, [[SpitefulAI but on your loss.]] Apparently the devs realized that most players would RageQuit at the loss of a single character, and as a result, multiple enemies would start streaming towards one character and kill them, ensuring you, as the player, lose, as you will have to reset.

* ''NintendoWars'', particularly ''BattalionWars'' but it can apply somewhat to the turn-based games themselves.

* ''Franchise/FireEmblem'', thanks to FinalDeath.

* ''Lemmings'', where you can try to save 100% every level - even when you only need 5%

** Lemmings 2: Tribes, is built on the idea of saving your lemmings, as you only get as many as you saved. Only the classic tribe requires you to lose any lemmings, meaning this is ''almost'' possible.

** There's also the Nuzlocke Challenge, in which the player is punished greatly if any of his party members ever faints. The Nuzlock Challenge is a sort of self imposed "hard mode" for a Pokémon game. In it there are rules about how often you may capture Pokémon, hough the specifics can vary from player to player. What doesn't vary is that any Pokémon that is knocked out is considered "dead" and can never be used again.

* ''MetalGearSolid'' allows you do this with enemies by using non-lethal weapon and even awards you for doing so, requiring you to do so to get the highest rank possible. It's possible to play through The Twin Snakes, 2, 3 and 4 with only a single kill throughout the whole saga: [[spoiler: [[TearJerker The Boss]]]].

* The main ''ZoneOfTheEnders'' games feature missions where the player is supposed to protect buildings with civilians and/or allied soldiers in obsolete mecha. One particular battle in the second game involves trying to protect 20 of these suits while fighting hundreds of enemies across a large battlefield. The only way for the main character to feel good about the outcome is to save every single one of them.

* Theoretically possible in ''{{X-COM}}'', although considering the ridiculously high early-game (and mid-game, and end-game) casualty rate, this is extraordinarily difficult even on Beginner, and flat-out impossible on any difficulty at or above Normal, unless you're willing to do a lot of SaveScumming.

* In TheLordoftheRingsOnline, the Tier 2 Challenge for Saruman's fight involves defeating him without anyone reaching zero morale, and within 30 minutes, or else everyone instantly dies.

* One achievement in ''MassEffect 2'' is for keeping everyone alive during the final mission.

* ''InTheHunt'' gives the player a special ending if the game is completed in one credit... [[DownerEnding Your submarine is shown in the wreckage of the enemy submarines, all destroyed along with the enemy base]].
