Apparently putting money down on the game nets you an exclusive level where you'll battle a gang of imaginary skeletons that Dr. Crane sics on you.
While his presence in the game isn't really a shock, his design is certainly a departure from what we've seen in the past. Note that the gas mask is a new addition to his usual sack mask. It's as if they're going down a Psycho Mantis route, isn't it?
I personally thought the way he looked in Batman Begins was sweet: just a mask and a suit that was kick ass.
