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.
