Developer Rocksteady has been working in the background for quite some time on the new Batman game titled Arkham Asylum and we were allowed a look at the game before release.
The snippet we seen was when Batman hauled the Joker back to Arkham in the passenger seat of the Batmobile. This story doesn't directly relate to any movie and it is instead set inside the Batman comic book universe. Gaming Heaven was told that Jim Lee's Wildstorm were involved and have created original character designs for the game. That said, things are that radical and all the characters, vehicles and weaponry all have a similar look to what they know and love.
