This DLC includes two new Challenge Maps for Batman: Arkham Asylum set in original locations from Arkham Island.

The "Insane Night" map pack will include two new challenge maps. The "Totally Insane" combat map lets players test their fighting skills against hordes of crazed escapees from the asylum's records facility; the "Nocturnal Hunter" map has players using Batman's gadgets and stealth skills to attack the Joker's goons from the shadows.
