KILLING FLOOR 2 places the gamer into continental Europe, about one month after the original KILLING FLOOR trials. Now the outbreak caused by Horzine Biotech's failed experiment has gained relentless momentum, essentially paralyzing the European Union - with all being methodically obliterated: communications, governments, and military forces alike, it is now up to a group of civilians, who have not yet given up hope to combat the outbreak and establish privately funded operation bases across Europe. New elements to KILLING FLOOR 2 are an enhanced level of carnage, with the visceral gore ramped up though a proprietary, high powered persistent blood system. As well as terrifying Zeds - novel enemies and fan favorites return with expanded and smarter artificial intelligence. Six player co-op or solo play is available, together with a unique blend of weaponry. An expanded perk system - with perks from the original game having been reimagined, and further brutal melee combat - reinventing the melee combat completely, make for a blood-splattered gaming experience.
