The Killing Floor Twisted Christmas Event

with Special Guest Team Fortress 2's Pyro. So if you people don't have Killing Floor, then I highly suggest you go get it asap. I've been playng Killing Floor for about a year, and it's an amazing game. And starting December 14th going to January 4th, KF will have a Christmas Even going on, which includes: 

-Free for everyone that owns Killing Floor (auto downloaded through Steam)
-All new level - Santa's Evil Lair
-All creatures in game replaced with Christmas themed monsters including the Gingerfast and the Nutpound
-More than double the achievement count with over 130 achievements
-13 new Christmas achievements
-Unlocklable "Baddest Santa" playable character
-Red or Blu Pyro from Team Fortress 2 playable character available to anyone that owns both Team Fortress 2 and Killing Floor (That's right! Pyro in KF)
-Mr. Foster's trademark gas mask and business tie as equitable items for the Pyro in Team Fortress 2 for anyone that owns or purchases Killing Floor before the end of the event
-All new difficulty level beyond suicidal - Hell on Earth
-Balance improvements
Along with that we're getting a new DLC pack: "London's Finest" It gives us another 4 characters.
