PC gamers sometimes get the shaft when it comes to demos but not with Batman: Arkham Asylum. An Arkham demo will be available on Friday, August 7th for the PC, PS3, and Xbox 360.

In Arkham, Batman brings Joker to Arkham Asylum for confinement. However, the Joker escapes and takes control of the facility. Now Batman is trapped in the asylum and must battle an army of former inmates. The demo is said to give gamers "a taste of the fierce FreeFlow combat system, the cunning stealth of the Invisible Predator mechanic, and the feeling of becoming the World's Greatest Detective."

The full game will arrive on all three platforms on August 28th.
