UPDATE 2: Warner Bros. Interactive UK has revealed new information on the Batman: Arkham City Game of the Year Edition.
It launches in the UK on 7th September for PlayStation 3 and Xbox 360 - over three months after the US gets it. No mention was made of the PC version.
The Harley Quinn's Revenge DLC adds more than two hours of fresh gameplay to the campaign, Warner said. Also included on the disc are all five previously released DLC packs.
Warner said those who already own the game can download the Harley Quinn's Revenge Pack, which will be available in all international markets beginning Wednesday, 30th May from the PlayStation Network and the Xbox Live Marketplace. Warner's original 30th April announcement was incorrect.
In the DLC you interchange between playing as both Batman and Robin to uncover Harley's plan. You "shut the gates on the urban mega-prison forever". There's a new storyline, new environments and a new gang of thugs.
The list of content for the UK version of the Game of the Year Edition does not mention the Batman Year One animated film, included in the US version.
The content in full:
- The DLC included on disc includes the Catwoman Pack, Nightwing Bundle Pack, Robin Bundle Pack, Challenge Map Pack and Arkham City Skins Pack.
- Maps: Wayne Manor, Main Hall, Freight Train, Black Mask, The Joker's Carnival, Iceberg Long, and Batcave.
- Playable Characters: Catwoman, Robin and Nightwing.
- Skins: 1970s Batsuit, Year One Batman, The Dark Knight Returns, Earth One Batman, Batman Beyond Batman, Animated Batman, Sinestro Corps Batman, Long Hallowe'en Catwoman, Animated Catwoman, Animated Robin, Red Robin and Animated Nightwing.
UPDATE 1: You can download the Batman: Arkham City Harley Quinn's Revenge DLC individually as soon as next week, publisher Warner Bros. has now confirmed.
The add-on will be available on 30th April, according to the Batman: Arkham City Twitter. Rocksteady's community manager has further clarified that date refers to the Xbox Live release only, where it will be priced 800 Microsoft Points (Ł6.80). PSN owners get it a day earlier - on a Sunday - for $9.99 (around Ł6.20, final UK price TBC).
ORIGINAL STORY: Broody adventure Batman: Arkham City is to receive a DLC-stuffed Game of the Year edition, including the previously-spotted Harley Quinn's Revenge DLC.
The Harley Quinn-focused expansion is described as the "final chapter" of Arkham City's story and looks to be set after the main campaign's climax.
Batman: Arkham City's Game of the Year edition will bundle the new Harley Quinn content with the pre-existing Catwoman, Robin and Nightwing DLC add-ons, plus the Arkham City Skin Challenge Map Pack.
You'll even get a download of the well-received Batman: Year One animated movie.
A new trailer for the new edition lists a 29th May US release date. It's likely that Europe will therefore see the game launch the following Friday, 1st June.
