Batman: Arkham City Game of the Year Edition will be released for Xbox 360 and PS3 on September 7, offering the original game plus all DLC packs, Warner Bros. Interactive Entertainment has announced.

In addition to all currently available DLC, the GOTY edition will also feature the upcoming Harley Quinn's Revenge pack, the final chapter in Arkham City.

Harley Quinn's Revenge mission sends players back into Arkham City to face their final challenge as they switch between playing as both Batman and Robin. Gamers must utilise each of the characters' unique combat and investigative skills to uncover Harley's vengeful plan and shut the gates on Arkham City forever. This content will be released May 30 as DLC for owners of the original game.
