Twelve minutes of Batman: Arkham City gameplay

Rocksteady have released a twelve minute video showing footage from Batman: Arkham City.
This is essentially a run-through of the demo shown at E3, and begins with a look at Catwoman before switching to Batman in the open-city area and a spot of beating up the local hoodlums.
For more on Batman: Arkham City, have a read of my E3 preview.
The game is due for release in October on PC, Xbox 360 and PS3.
