This is an action game featuring characters from the Batman franchise. Players assume the role of Batman as he fights (never kills) his way through a psychiatric hospital populated by psychopathic criminals and humans infected with a toxic virus. Players can punch, kick, and use weapons (spikes, light beams, and other gadgets) to defend against the onslaught of enemies. Some attacks are highlighted by special effects, such as slow-motion hits and close-ups of damage inflicted. During the course of the game, players can enter rooms with blood stains on the ground and walls or witness the "infected" twitching and screaming in pain. Some inmates and guards are strewn unconscious/dead on the asylum floors, while others are tied-up, strapped to torture devices, or are being tortured (e.g., a guard suffering in an electric chair). Two female characters wear provocative outfits that expose deep cleavage and/or partial buttocks, and one of them moans suggestively when she is in peril. Players are occasionally required to identify and track traces of whiskey/tobacco during missions. Some expletives (e.g., "b*tch," "damn," and "pissed") can be heard in the dialogue.
