As you can see here, the next issue of Game Informer is to carry an exclusive reveal Batman Arkham Asylum.
It’s an Eidos game, developed by Rocksteady. Blurb:
This completely original title explores Gotham City’s darkest location, the infamous Arkham Asylum. But as a routine prison transfer goes wrong, the Joker sets his demented plan into action and Batman comes face to face with an army of his worst enemies. In a dark and gritty setting reminiscent of Bioshock (with a story co-written by Paul Dini), Arkham Asylum is setting the stage for a true-to-character Batman game.
