Underworld Unleashed: Batman - Devils Asylum

Argumento

As Underworld Unleashed engulfs the DC Universe, Neron's corrupting influence has intensified the madness and evil already concentrated within the walls of Arkham Asylum. Into this deadly mix comes a new inmate who has poisoned the Asylum's other residents, and the antidote carries a price only Batman can pay...with his soul! Written by Alan Grant.
