Tripwire Interactive has announced the launch of its Killing Floor Twisted Christmas events. Running until January 4, 2011, this update also comes at the same time as the Team Fortress 2 Pyro character and a new DLC character pack.
The event will feature the new level Santa’s Evil Lair, Christmas versions of all the enemies, and 12 holiday achievements; unlock all for a permanent Baddest Santa playable character. The game will also see a 66 percent discount on Steam for a limited time, so pick it up at http://store.steampowered.com/app/1250/.
