Horrorshow Quake represents a new style of deathmatch play. The basic concept is that one player is the Killer and the rest are Victims. The killer has many advantages and the victims must use team work to stay alive and keep the killer from accomplishing his goal, which is to reach the fraglimit. Horrorshow takes this idea and puts it in a frightening setting with cool new models, characters, and weapons.
