Here's another free weekend courtesy of the cats at Steam. This time, it's Killing Floor. The promotion will start up tomorrow, so now would be a good time to commence pre-loading the game while you still can.
Co-op for six players, a survival horror-style setting, and the fact that you'd normally have to put up $19.99 to play Killing Floor add up to be a pretty convincing argument for why you should be excited. Or, knowing how jaded the Internet can be, you should at least have a reaction other than "meh."
Is that too much to ask? Oh. It is. Hey -- don't say I didn't try.
