Much has change in Arkham since the last time you've visited the Asylum. And much has stayed the same. The New things build on the old, and the old makes you feel right at home. Arkham City expands on the formula Rocksteady created with Arkham Asylum. Though the changes aren’t a complete revamp of the games original design, the improvements made to the game are ones that once again set it apart as the best superhero game ever created; a title securely held by the games previous installment.
