We now propose three new images of Batman: Arkham City primarily to show us the "Fun House" of the Joker in Arkham City. We can also see some weird people, Joker aside, that will give hard time to the Dark Knight. Among these an awful brute without an arm, but with a very noticeable scar and a really big hammer. We leave you with images reminding you that Batman: Arkham City will arrive in the autumn of 2011.
