In Killing Floor 2, players are transported to continental Europe, where a botched experiment has spiraled out of control, taking on an unstoppable power and paralyzing the entire European Union. Just a month after the events of Killing Floor, clones have spread to virtually every corner of the globe, and civilization is in complete disarray. Communication is disrupted, governments are in disarray, and armies have been systematically decimated. The people of Europe who were lucky enough to survive are now hiding from the horrors of the everyday world.
