Arkham Asylum, the legendary home for the criminally insane, now lies in ruins.

But watching alone won’t stop the killings that begin almost immediately in “Arkham Manor.” To find the predator responsible, Batman must become an inmate himself. Now the World’s Greatest Detective begins the most dangerous undercover mission of his life, working with - and against - the resident doctors, guards, and ghoulish supervillains to crack the case. Can he catch the killer and restore order to the chaos? Or will the insanity of Arkham Manor claim the mind of its latest patient?
