Batman Arkham City Trailer

The first one was great and the second one, Batman: Arkham City, also this great. In this one we have new villains, Two-face, Mr. Freezes,Hugo Strange, and there are many others. Some villains are also returning, like Joker and Harley Quinn, and IGN thinks that Black Mask, is in this trailer, I don't know but it looks like him. The gameplay remains mostly the same from the first one, but this time it's open world. Most if not all of the voice cast is returning.
