A gamemode of deception and murder, based off of Murder in the Dark. One person is a murderer with a knife, who is trying to secretly kill off the other players. The other players must use their wits to find out who it is and kill them first. Unfortunately they only have the one gun between them.
Requires Counter Strike: Source, you must own it and have it installed. If you don't have the maps, textures or some models you most likely are missing CSS.
