Killing Floor is a Co-op Survival Horror FPS taking place in the devastated cities and countryside of England, after a series of cloning experiments for the military goes horribly wrong. You and your friends are members of the military and police, dropped into these locations with a simple mission: survive long enough to cleanse the area of the failed experiments. The only problem is, these “experiments” aren’t waiting to be taken out – they’re coming for YOU! The Killing Floor Gold Edition retail box, coming in a slipcase packaging with brand new cover, is a tribute to hitting the 1 million copies sold milestone. It will include the base game, all DLC available to date and most importantly, a brand new female character which will also introduce female voice overs for players in the game, supported in English, German and French.
