Batman: Arkham Asylum Demo

Step into the depths of Arkham Asylum - Gotham City's psychiatric hospital for the criminally insane
Eidos Interactive has released a playable demo of Batman: Arkham Asylum which opens as the Dark Knight and Commissioner Gordon return The Joker back into confinement at Arkham Asylum (thanks: Blues). But things soon fall apart as The Joker gains the upper hand and springs a trap, setting Arkham Asylum's occupants upon Batman. The demo offers 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 as they navigate Arkham Asylum's Intensive Treatment facility. Players can unlock character bios, as well as get a sneak peak at some of the infamous foes that Batman will encounter within the cavernous and macabre confines of Arkham Asylum. Batman: Arkham Asylum will hit the store shelves in the UK on August 28th.
Update: the demo is also available on Xbox LIVE Marketplace for Xbox 360 and PlayStation Network for PS3.
