Tripwire Interactive are thrilled to announce that Killing Floor has sold more than 1 million copies on PC – and is still selling strongly! This is a major achievement from any game studio as few games, even multi-million-dollar AAA titles, ever sell over 1 million copies on PC. As a truly independent outfit who have funded ourselves all the way, we are particularly proud of the achievement. Our thanks go to all the developers of the Killing Floor mod and everyone on the team here at Tripwire Interactive, who’s continued support has made the game such a huge success. We would also like to thank all the members of the community who have made maps and other add-ons for the game, with the Killing Floor SDK. And, most importantly, we offer our thanks to all of the fans and everyone who has bought the game over the past two years and helped make Killing Floor the cultural phenomenon that it is today.
