Tripwire Interactive is proud to announce a special event for its highly successful co-op sci-fi horror FPS PC title, KILLING FLOOR 2! Starting Thursday, April 28th at 10AM PST / 1PM EST through Monday, May 2nd at 10AM PST / 1PM EST, participating players will be able to earn double XP for all perks. In addition, the item drop rate will be increased to once every 24 hours during this time period – a rare opportunity for fans to pick up must-have items.
After the recent inclusion of the Killing Floor franchise’s first ever Versus Survival PvP game mode where players have the option between taking control of either a deadly Zed or human hell-bent on survival, there has never been a better time to take advantage of this limited time event!
