Batman: Arkham City is one of the highest reviewed titles of 2011 and with the release of the Batman: Arkham City Game of the Year Edition, fans can extend the multi-award winning experience as the Dark Knight with Harley Quinn’s Revenge, the final chapter in Batman: Arkham City that adds more than two hours of original gameplay to the critically-acclaimed interactive title. Also included on disc will be all five previously released downloadable content (DLC) packs.

The Harley Quinn’s Revenge mission sends players back into Arkham City to face their final challenge as they interchange 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 the urban mega-prison forever. In addition to experiencing a new storyline, fans can explore new environments and face-off against Harley’s all new gang of thugs.

The DLC included on disc includes the Catwoman Pack, Nightwing Bundle Pack, Robin Bundle Pack, Challenge Map Pack and Arkham City Skins Pack.

All told, Batman: Arkham City Game of the Year Edition packages new gameplay content, seven maps, three playable characters, and 12 skins beyond the original retail release:

• 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 Halloween Catwoman, Animated Catwoman, Animated Robin, Red Robin and Animated Nightwing

Batman: Arkham City builds upon the intense, atmospheric foundation of Batman: Arkham Asylum, sending players flying through the expansive Arkham City – five times larger than the game world in Batman: Arkham Asylum – the new maximum security “home” for all of Gotham City’s thugs, gangsters and insane criminal masterminds. Featuring an incredible Rogues Gallery of Gotham City’s most dangerous criminals including Catwoman, The Joker, The Riddler, Two-Face, Harley Quinn, The Penguin, Mr. Freeze and many others, the game allows players to genuinely experience what it feels like to be The Dark Knight delivering justice on the streets of Gotham City.
