Storyline

Some time after Batman’s disappearance, Catwoman, eager for revenge against The Riddler for holding her hostage, finds the location of Riddler's HQ, located in Winslow’s Toy Shop. After obtaining the necessary key cards and knocking out the guards, Catwoman unlocks the hidden entrance to Riddler’s robot factory, hidden beneath the shop. At the same time, Riddler, still incarcerated at the Gotham City Police Department, attempts to communicate with his factory’s AI system in order to command his Riddlerbots to free him (which he feebly disguises as a call to his lawyer). Catwoman taunts him over the phone, detailing her plan to steal his money and destroy his factory as payback for his actions against her. Furious at this notion, Riddler activates the factory’s security measures, including Riddlerbots, lasers, an electrified floor, and a giant buzzsaw device similar to ones used in other traps of Riddler’s. After evading the traps and destroying the robots, Catwoman reaches Riddler’s main computer and proceeds to empty his accounts before activating the factory’s self-destruct sequence, leaving an irate Riddler stuck in jail to be tasered by Cash (who has caught on to Riddler’s antics).
