Ra's al Ghul recruits Professor Pyg, Mister Toad, Magpie, Tobias Whale, Phosphorus Rex, and Cypher to eliminate Batman in return for control of a piece of the city. Batman races to find his location and save both his partners and the entire city, while Lt. Gordon and Barbara attempt to hack and disable the Ion Cortex once and for all.

Batman and Katana team up with Rex Mason (who has been classified 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.
