This game is currently free to play through Steam until Sunday at 1pm Pacific. In addition it's 50% off so down to $20 (originally launched at $60 despite many people feeling it wasn't a $60 game).
Just a heads up for anyone interested in checking it out free of charge. Definitely seems like the type of game that's better with friends, but could be tolerable in PUGs.
I got nothin' clever to say.
