Some of the games in this list are "prospects" that our own contributors haven't tested, but have heard can be won without killing anything. (If we find out that we've been misinformed about any games on the list, we'll move the game to the "pacifist challenge" list instead.)
Disclaimer: Some zero kill run games take place in graphically violent and/or disturbing game worlds, regardless of whether a player can get through them with zero kills, so parental/viewer discretion is always advised.
