Yesterday Tripwire Interactive celebrated 10 years of the Killing Floor franchise, and we've found out that the series has sold nearly 10 million units and has been played by over 15 million unique players. What's more is we also hear that it's earned over $100 million USD in franchise revenue over the decade.
Over Killing Floors 1 and 2 we also know that over 75 billion zeds have been killed, and to celebrate this and all the other accomplishments of the last 10 years, Tripwire is hosting a Steam publisher sale right now that runs until May 20, which you can see more of here.
On May 21 we can also expect to see Killing Floor: Double Feature launch, which bundles together Killing Floor 2 on PS4 and Killing Floor: Incursion on PSVR. Mrs. Foster will also be a playable character, and all the seasonal content since Killing Floor 2 launched is also thrown in there.
Have you tried Killing Floor in any form?
