Play Battleblock Theater as a Castle Crashers knight, Alien Hominid guy

Battleblock Theater launches tomorrow on XBLA, but two previous games from The Behemoth have been taking up space (and topping the sales charts) for years, Castle Crashers and Alien Hominid HD. Finally, all the hours of enjoying these games pays off, in the form of special unlocks in Battleblock Theater. Owners of Castle Crashers can play as that game's knight in Battleblock Theater, and owners of Alien Hominid HD can get the alien for Battleblock Theater.

Intrepid players are able to unlock the "Can't Stop Crying" pack in Castle Crashers on XBLA by earning at least one achievement in Battleblock Theater, as long as both games are up-to-date and installed on the same system. With the Can't Stop Crying pack, earning achievements in Castle Crashers and Alien Hominid HD unlocks special heads in Battleblock Theater, and earning achievements in Battleblock Theater unlocks Hatty Hattington, that game's protagonist, for Castle Crashers.

Both Alien Hominid HD and Castle Crashers are on sale for 800 MS Points on XBLA, now through April 4.
