BattleBlock Theater is an in-development co-operative / competitive platformer video game and the third production from developer The Behemoth following Alien Hominid and Castle Crashers. Set to be released in 2010, the company originally revealed an early playable version of the game at the Tokyo International Anime Festival on 16 March 2009 with a trailer of gameplay footage. The game has been announced for Xbox Live Arcade, with other possible formats yet to be confirmed. Programmer Tom Fulp, creator of The Behemoth’s origin project Newgrounds, is said to be focusing on other Newgrounds projects rather than playing a prominent part in this game’s development.
