OK, so we kind of cheated ... The 17 screenshots are from the new trailer that we posted, which gives us a little background on how and why the game takes place in Arkham.
The video also gives us a little information on some of the foes that Batman will be duking it out. The Joker goes without saying, but it also looks like Killer Croc, among others, will also make an appearance!
Make sure and head over to the Batman: Arkham Asylum pictures area to check out the new screenshots!
