In either Co-Op or Solo mode, players engage hordes of AI controlled Zeds across multiple waves until they reach the boss or die trying. The players can select from a variety of perks, each with its own skills, powers, and weapons, in addition to choosing from among several playable characters with different appearances and personalities. Against the players are arrayed a multitude of Zeds, from lowly, slow clots to bosses like the mighty Patriarch.
A PvP version of Survival for up to twelve players, in this mode two teams of up to six players each take turns playing humans vs. Zeds, each match lasting four waves plus a boss wave. One team plays human and the other a mixture of specially modified Zeds backed up by AI controlled Zeds until the human team is defeated or it defeats the boss, at which point the two teams switch sides and the battle continues. After each team has a turn playing both humans and Zeds, they both receive a score based on their performance and the higher score wins!
A covert Horzine research facility, the Biotics Lab has been overrun by the Zeds created in its own depths. The facility must be retaken before the Zeds have a chance to threaten the world outside the lab. Full of steel and glass, it is a maze of corridors, experimental labs, and horrors.
Once little more than a disused cottage located deep in the Black Forest of Germany, a crashed Horzine cloning unit has brought blood and terror to this tranquil woodland scene. Now the Zeds must be contained before they spread further through the heart of Germany.
Paris has been invaded by vast numbers of Zeds, devastating the city and scattering the population. Now it is up to the players to take back City of Lights in vicious street to street fighting.
Not only are the streets of Paris filled with Zeds, but the catacombs beneath them as well! The historic, bone filled tunnels beneath Rome, Italy have become home to an army of Zeds, requiring survivors to brave the bones and darkness to remove them.
Space is not even safe from the Zed outbreaks! A Horzine research space station has become infested with Zeds and it must be retaken before it falls to earth. In space, everyone can hear you shatter Zed skulls…when you’re inside a space station that is. Outside a space station, not so much.
Many tried to flee the Zed outbreaks and only some succeeded; many more died in the attempt. This ferry port in Helsingor, Denmark was overrun by Zeds while the refugees tried to board the ferry; it is too late to save the refugees, but not too late for revenge.
Small farmhouses like these are scattered across the rural regions of Europe. The unlucky ones have become infested with Zeds and must be cleaned out before the Zed presence has a chance to fester and grow.
London continues to be a battleground between survivors and Zeds, both above ground and below. The original outbreak was contained, but now smaller outbreaks regularly plague the historic city.
Hell. Zeds in Hell with lots of flame, bones, and huge clocks. Don’t ask questions; it’s Zeds in Hell, it’s cool.
This historic mansion is the hereditary home of Dr. Hans Volter, once a Nazi scientist and now one of the masters of the Zed invasion. In addition to vaulted ceilings, beautiful wood paneling, and a vast library, this massive mansion has a selection of scientific torture rooms in the basement.
Located north of the Arctic Circle, contact was lost with this remote experimental facility in the wake of the early European Zed outbreaks. Now teams are being sent to find out what happened to Outpost facility and if any of the staff are still alive. Unlikely.
Some of the Horzine Biotech research facilities were attached to prisons in nations where prisoners were available for use as test subjects for the right price. Now these prisons have become charnel houses of blood and terror as Zeds rip through the prison populace.
When the erupting volcano is the least of your worries, you know your tropical island vacation has gone awry. Welcome to Zed Landing! Thanks to a crashed Horzine cargo plane, this island has become infested with Zeds, all of whom want to eat you before the volcano cooks you. Or after really, they’re not that picky; Zeds are into barbecue.
The Descent is a series of underground chambers beneath Volter Manor. These rooms represent the more secure facilities used by Hans in his experiments and need to be cleaned out to put a stop to his terrible work.
Nuked is the burnt and broken remains of a city that has a Zed problem on top of an incoming nuclear attack. Don’t stare directly at the nuclear flash and remember to duck and cover!
Once a place of laughter and joy, this carnival is now a nightmare of blood, screams, and death. The crowds no longer come to see the shows and enjoy the rides; they come to kill you. So don't let them. At least some of the carnival games and rides still work.
Visiting the nightmares of anyone would be harrowing, but visiting the nightmares of a psychopathic clown named Boozo? That is the worst.
In KILLING FLOOR 2, players descend into continental Europe after it has been overrun by horrific, murderous clones called Zeds that were created by the corporation Horzine. The Zed outbreak caused by Horzine Biotech’s failed experiments has quickly spread with unstoppable momentum, paralyzing the European Union. Only a month ago, the first Zed outbreak from the original KILLING FLOOR ripped through London; now the specimen clones are everywhere. Civilization is in disarray, communication networks have failed, governments have collapsed, and military forces have been systematically eradicated. The people of Europe are now focused on self-preservation, the lucky few who survived having gone into hiding.
But not all have given up hope; a motley group of civilians, soldiers, and mercenaries have banded together to fight the outbreaks from privately funded bases across Europe. When a specimen clone outbreak is detected, the players are sent into Zed-laden hot zones to exterminate all threats using whatever means necessary. Welcome to the Killing Floor.
Fighting Zeds isn’t all gore and gaping chest wounds; sometimes you can find some really snazzy looking gear in the process. As you play, you will be rewarded every so often with a variety of cosmetic items, from cowboy hats to suits of cardboard armor to neon colored weapon skins. There are hundreds of cosmetic items available in game and new ones are regularly added. Cosmetic items can be used to customize your appearance in game, traded to other players (PC only), or even broken down into crafting components to make other items.
