Tripwire are having a busy weekend, with the announcement of Killing Floor's now-traditional Christmas spectacular, and a free weekend on Steam for Red Orchestra 2. This Christmas' Killing Floor event is IN SPAAAACE, which puts robots and Evil Santa on the moon (a free map with Christmas-themed baddies). Could anything be more festive? Watch the trailer below, and decide for yourself.
R'ochestra meanwhile is free from now until Monday. It's a fantastic, rumpled bastard of a game. Worth a few squeezes of the mouse button.
