One of the twelve Stages found within Injustice 2 is the Arkham Asylum. As the name suggests, this is the insane asylum in Arkham City that houses all the criminals deemed mental unfit to be placed in prison. Long ago, the Joker was one of the inmates of the Arkham Asylum, placed there after losing one of his famous fights to Batman. The Asylum no longer has the same sense of both fear and madness now that the Joker lives no more, but the current inmates are sure to show you a fund time if you play here.
