I’m a little bit late to the party on reporting this news, but Rocksteady will release a GOTY edition for last year’s smash hit Batman: Arkham City on May 29th/2012. The GOTY edition will come with all of the DLC that has been released (the Catwoman, Nightwing and Robin packs among others) and a downloadable copy of the Batman: Year One animated film.

But that’s not all folks! For weeks I’ve reported on the rumors surrounding new single player content for Arkham City and now I’m glad to say that it finally exists. The content is billed as the “Final Chapter” and titled “Harley’s Revenge”. The chapter takes place after the conclusion to the main game. For those who already own the game and don’t want to upgrade to the GOTY edition, “Harley’s Revenge” will be available for download on May 29th as well.

No price point has been formally announced for either the retail game or the DLC expansion.
