Descend into continental Europe where the outbreak caused by Horzine Biotech’s failed experiment has quickly spread and gained unstoppable momentum, essentially paralyzing the European Union. Just one month after the conclusion of the events in the original KILLING FLOOR, the specimen clones are everywhere and civilization is in disarray; communications have failed, governments have collapsed, and military forces have been systematically eradicated. The people of Europe know survival and self-preservation too well and lucky survivors have gone into hiding. Not all have given up hope though... A group of civilians and mercenaries have banded together, paid for by Horzine, to combat the outbreak and established privately funded operation bases across Europe. Upon tracking specimen clone outbreaks, players will descend into zed-laden hot zones and exterminate them.
A semi-destructible medium-sized map taking place in one of Horzine's scandinavian bio labs. Traverse a high-tech facility and combat the zed in a variety of different locations, many of which will suffer cosmetic damage from your stray bullets and concussive explosions. Cytology Lab is an intense and challenging map rich in visual detail and highly optimized for maximum performance (although slow-downs may be expected when using explosive weapons due to the huge number of breakable objects). The overall map layout uses the classic 'horse shoe' design allowing you to endlessly circle the base's perimiter, while multiple connecting side areas and traversible air vents allow for shortcuts, escape routes and resource scavenging. The end result is a map with a very kitting-friendly gameplay that retains a high skill cap which will challenge even hardened KF2 veterans to stay alive.
