The Behemoth is celebrating their 10th anniversary (and Dan Paladin's birthday week -- happy birthday Dan!), and to celebrate, you can get Alien Hominid HD, Castle Crashers, and BattleBlock Theater for 50% off on the Xbox Live Arcade. The sale will last until September 16th, and I highly recommend at least picking up Castle Crashers if not all three, especially if you have any local friends to play co-op with.
All in all it's been a pretty interesting decade for Behemoth, and I hope they keep making games. It'll be really interesting to see if they keep supporting Microsoft via the Xbox One, or branch out into the increasingly indie-friendly marketplace elsewhere.
