"The team at Rocksteady put every ounce of effort into making the best Batman experience we possibly could, so we are overwhelmed by the incredible feedback from the community."

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.

Batman: Arkham City is based on DC Comics' core Batman license and rated "T" for Teen by the ESRB. The game is currently available on Xbox 360 and PS3™.
