Batman: Arkham City builds upon the intense, atmospheric foundation ofBatman: Arkham Asylum, sending players soaring into Arkham City - five times larger than the game world in Batman: Arkham Asylum - and the new maximum security "home" for all of Gotham City's thugs, gangsters and insane criminal masterminds. Set inside the heavily fortified walls of a sprawling district in the heart of Gotham City, this highly anticipated sequel introduces a brand-new story that draws together a new, all-star cast of classic characters and murderous villains from the Batman universe, as well as a vast range of new and enhanced gameplay features to deliver the ultimate experience as the Dark Knight.
