Killing Floor's Twister Christmas has started this year and will go on all they way until January 4th. The new event includes an underground snow map with 7 new guns to decimate all the mutated freaks. There will also be new achievements for players to complete in order to unlock the Baddest Santa playable character.
For those that don't have Killing Floor, then there is good news for you, because the game is 75% off right now. If you want to try the game out before you buy it, then take advantage of the free weekend that is going on right now!
