[mwb1100]

For the next day or day and a half or so Humble Store is giving away free steam keys for some zombie game: Killing Floor

It's a pretty popular game on Steam; I used to play it, but haven't recently.  It is a pretty good game.  The one caveat is that this is Killing Floor 1, and there is a Killing Floor 2 that many (most?) people have moved on to.  That's on sale also for half off (14.99).

Update: It's a steam key, and must be redeemed by 7/1.  I already have it on steam, so if someone wants the key (an established DCer is the only requirement), just let me know.
