Warner Bros. has announced a new edition of Batman: Arkham City in the form of the Game of the Year Edition.

Set for release on September 7 for PlayStation 3, Xbox 360 and PC, the critically acclaimed title will be repackaged with all five previously release downloadable packs, as well as the newly announced Harley Quinn’s Revenge.

The new DLC will be available for download on May 30 via the PlayStation Network and Xbox LIVE Marketplace, as players are sent back into Arkham City to face their final challenge as they interchange between playing as both Batman and Robin. It’ll feature a new storyline, new environments and a face-off against Harley’s all new gang of thugs.
