This Christmas Tripwire Interactive has a whole new twist on killing the undead playable right now: Zeds in Space! Horzine's Moonbase is the setting for the new map, on the dark side of the moon. One small step for Zed? Actually, giant leaps for Zedkind, up there in low gravity. You'll believe Zeds can fly - and they certainly will when you smack them with the new Dwarfs!? Axe. If they are jumping around too much for your tastes, hit them with the stasis field on the Zed Eradication Device, which can be found scattered in pieces around the new Moonbase map. Or just zap them. There is a brand new weapon for the Medics amongst you, too - the Schneidzekk Medic Gun, with a nice high rate of fire AND healing darts. New achievements too, naturally.

As always, you only need to own Killing Floor to play all of this for free from now until 4 January. To use the Dwarfs!? Axe, you just need to earn 40,000 gold in Dwarfs!? Free-to-Play ( http://store.steampowered.com/app/213650), or buy/already own the full game  ( http://store.steampowered.com/app/35480/).

All your old favorites are back for Twisted Christmas III as well: all the Christmas specimens are back, along with another opportunity to unlock Baddest Santa, for those of you who haven't had the chance.

On top of all that free stuff, there is also a new weapon pack, for those that like to bling out their armory. There are gold-plated versions of the AK-47, the Combat Shotgun, Katana and the M79 - which even gets its own matching, shiny rounds! And a very special single character pack, in the science fiction theme: Horzine's Domestic Assistance Robot (DAR, to its friends), cleaning up the cosmos, one specimen at a time!

The new weapons, new map and the whole Twisted Christmas event is now available. Christmas Zeds. A Moonbase map in low gravity.  Baddest Santa is only unlockable during the Twisted Christmas event - so don't miss out! For more information, take a look at the web page for the event:
