Tripwire Interactive has announced Killing Floor 2 has become one of the top-selling Steam Early Access titles to ever be released as it has exceeded over one million units sold.

Killing Floor 2 was released as a Steam Early Access game on April 21, 2015, giving it a year and a half to reach one million units sold. In that time, Tripwire has received invaluable community feedback as it prepares for the title’s full release and beyond.

Speaking of its release, Tripwire is also announcing Killing Floor 2 will receive a full release on PC, PlayStation 4, and PlayStation 4 Pro globally on November 18th. Deep Silver will be handling the publishing of the game globally.

Since its Early Access debut, Tripwire has been regularly adding new content to the game, which includes new boss characters, new locations, and new classes to assist in fighting off hordes of Zeds. We've been fans of the Killing Floor series for a long time, and we highly recommend checking out Killing Floor 2 when it releases next week.
