The much awaited demo for the Batman: Arkham Asylum was released on August 7 2009 for PC, PS3 and Xbox 360. Batman: Arkham Asylum is an upcoming title of the action-adventure stealth genre from Rocksteady Studios and is based on DC Comics' Batman. This title in which most of the game is played from Batman's perspective through an over-the-shoulder, third person perspective, is slotted for a September 2009 release for PC and a late August release for PS3 and Xbox 360.
