Rocksteady Studios has released a great looking teaser to the sequel to Batman: Arkham Asylum this time called Arkham City. The teaser doesn’t give much info on the game other than the return of Joker. Really can’t wait for this one, the first one was great and if you haven’t played it you should really check it out. Here is a link to the official page. Also after the trailer take a look at some of the screen shots of Catwoman, Two-Face, and Batman kicking some ass (also from the game.)
