We first saw this trailer on the same episode of GameTrailers TV that aired the new Punisher: No Mercy trailer.
For those that haven't heard, Eidos and Warner Bros. have teamed up to create a new Batman video game that takes place in Arkham Asylum.
We have several Batman: Arkham Asylum screenshots, as well as a Batman: Arkham Asylum wallpaper that we created using the splash page from the official site.
It's early, but the screenshots and teaser trailer look promising so far...
