New "Batman: Arkham Asylum" trailer, now with more Joker

Batman: Arkham Asylum takes a look at the darker side of the Dark Knight's world. It's nothing compared to the ruthless, brutal world of LEGO Batman, mind you, but it's still pretty dark. The game has potential to mix the world of Batman with the gameplay of Metal Gear and Bioshock. So here's hoping that they don't mess it up.
