The Tripwire guys do like a bit of seasonal celebration in their Killing Floor. This year they’re gifting us with “the Winter Weapon Pack, with seven brand new weapons complete with new achievements, free to everyone who owns the game” but there’s also an entirely new level, the Ice Cave, which you can check out for free, even if you do not own the game, thanks the free weekend on the Steam from Thursday 8th to Sunday 11th December. There’s other exciting new DLC, too, such as the Steampunk pack, which lets you dress like one of those digital distribution punks, I think. Hmm.
