Warner Bros. Interactive Entertainment, Rocksteady Studios, and DC Entertainment are hard at work on Batman: Arkham City for the Sony PlayStation 3, Microsoft Xbox 360, and PC for release in October, so to keep us all intrigued and interested, a new video has been released that showcases over ten minutes of solid gameplay from what I'm assuming is an early section of the game.  You'll see how Catwoman works as a playable character, what brings Two-Face into conflict with Batman, which new gadgets the Dark Knight has in his utility belt, where the Joker is hiding, and much more.  I won't spoil everything here.  Watch and be impressed for yourself.
