The game is out of the zeitgeist these days, but is a lot of fun and has had significant updates since it was last mentioned on Giant Bomb. I bought a four-pack and never found interested friends, so to you this bounty comes.
It's a Steam game, Windows only. Check out the Steam store page for more details. First come, first serve! Please don't ask to just add to your expansive Steam library; the game is worth a play.
*That's it, thanks for taking them off my hands.
