Tripwire Interactive has announced that Killing Floor has surpassed over 5 million units sold worldwide. In addition, the team has released a brand new free content update for Killing Floor 2, Killing Floor 2: Infinite Onslaught.
Bill Munk, Product Lead for Killing Floor 2 at Tripwire Interactive, said:
“Continued sales for both the original Killing Floor and Killing Floor 2 post-launch is the kind of thing that can’t happen unless we keep things new and exciting for players. That’s why post-launch content updates and continued support for the Killing Floor community continues to be a top priority for us.”
As the press release reads, Tripwire Interactive continues to support the Killing Floor 2 community with free post-launch updates and promoting community made maps with today’s release of the Infinite Onslaught Content Update. Highlights include:
NEW ENDLESS MODE GAME TYPE
- Challenge the relentless waves of Zeds that become increasingly crushing as more waves are defeated while The Patriarch takes over in the role as The Trader
NEW WEAPONS
- MAC- 10 SMG: Voted back by community popularity, the MAC- 10 SMG makes its triumphant return from the original Killing Floor, featuring incendiary ammo
- Husk Cannon: Requisitioned from a Husk, it is time to bring more fire to the party
- AF2011-A1 pistol: Killing two Zeds with one stone was never easier than holding the lovingly designed two-for-one pistol
NEW PLAYABLE CHARACTER D.A.R.
- Short for Domestic Assistant Robot, this new and improved fan favorite machine from the original Killing Floor is now freely available for Zed destroying services
NEW MAPS
- Powercore: Designed by a community mapper, the subterranean facility is yours to defend
- DieSector: The Patriach was very original when naming his new testing arena for his latest and greatest creations
NEW COSMETICS, CRATES, ACHIEVEMENTS, AND MORE
- The Vault has been stocked with additional cosmetics, character skins and weapon skins

Thr first one is mutch better .
All I want is Red Orchestra 3. Bring me back home to Stalingrad Tripwire.
Killing Floor 1 is legendary, glad to see it’s still selling relatively will. KF2 was kinda a let down, tbh.
Must have sold a lot on console since the PC copies stand at 1.7 million and those are heavily inflated since this game had a Free Weekend last year.
The game has been on Humble Bundle as part of the sub 15 dollars package at least once that I can remember and probably has been for sale a few more times. It also goes on Sale for cheap on Steam almost every time they have a sale.
Stays true to the original killing floor, but beyond that brings nothing new to the table beyond gore mechanics, skins and a few new weapons.
True, and they did some damn fine work on the gore and gun animations for as little as it does to update the formula. But then again, how should Tripwire have updated it since it’s always been a fairly basic idea since the days of it being a mod.
