Batman and Katana team up with Rex Mason, also known as the "Golem of Old Gotham", as they combat an increasing army of armored thugs that have been terrorizing several parts of Old Gotham. In addition, they also dodge Harvey Dent's newly-created Special Crimes Unit, which is ordered to take down both the armored criminals and the vigilantes fighting them.
Batman once more patrols the streets of Gotham City. Batman brings justice to the likes of The Joker, The Penguin, Professor Pygg, and more treacherous forces seeking to blanket the city in their arcane menace.
Along with backup from ex-secret agent Alfred and lethal swordstress Katana, the Dark Knight faces the twisted machinations of Gotham City's criminal underworld led by the likes of Anarky, Mister Toad and Magpie.
