The sequel will be known as Batman: Arkham City and is set for a release somewhere during Autumn 2011 for PC, Playstation 3 and Xbox 360.

Characters that have been confirmed to be featured in the game include Catwoman, Two Face, Mr. Freeze, Talia al Ghul and the Riddler. Mark Hamill had already confirmed that he he will be returning to voice The Joker, though he indicated that this will be the last time he will take on this role.
