A game published by Steve Jackson Games - or not, really, as it's a game that has been played in colleges all over and just standardized by SJG. The game involves all the players attempting to assassinate each other. It is not a war game like paint ball; all the killing attempts must be subtle. Of course, you aren't really trying to kill anyone - you use mock weapons and traps like alarm clocks for bombs, string or a laser pointer for a tripwire, Nerf weapons for a gun - stuff like that. Many variations exist.
