Batman: Arkham Asylum is one of the top-rated games to have been released this year. It’s only been out on PC, PS3, and Xbox 360 since the summer yet a sequel has already been announced.

This is the first look video trailer for Batman: Arkham Asylum 2. It doesn’t show much – being just a teaser and all – but The Joker is back and causing mayhem once again.

Superhero games have been notoriously bad over the years, with developers seemingly unable to grasp the gameplay mechanic required to make Superman, Batman, Spider-Man and the rest come to life in games.

Batman: Arkham Asylum managed to pull it off and it’s obviously hoped the sequel will be as good if not better than the original. The game was announced at the 2009 Spike TV VGAs, and a new Web site named ArkhamHasMoved is now live.
