Warner Bros. and DC Entertainment recently unveiled a killer 12-minute clip of gameplay from the upcoming Batman: Arkham City.

Now here's even more gameplay footage - picking up right where the previous clip left off, no less! This demonstration, from Rocksteady Games marketing manager Dax Ginn, is from Japan Expo 2011, which is the same carnival of awesome that played host to the dancing Ironettes.

Batman: Arkham City will be released in the U.S. on October 18.
