Batman: Arkham City loses the confines of its predecessor's island asylum for the more expansive slums of Gotham City. Arkham warden Quincy Sharp has been elected mayor and has requisitioned the city's downtrodden district as "Arkham City," the new holding area for all of the crazies and dangerous types from Arkham Asylum and Blackgate Prison, with Hugo Strange appointed as overseer. This prison city has been sealed tight by a heavily guarded perimeter, keeping all of that danger festering inside.

In addition to the unchecked crime produced by a population composed entirely of criminals, Batman also has to deal with Two-Face, who's captured Catwoman and plans to publicly execute her within Arkham City.

At a Microsoft press event this week, a reprentative from developer Rocksteady offered us our first guided demo of the city and some of Batman's enhanced gadgets, including the revamped Detective Mode.
