The cosmic war with Apokolips is over, but a new dystopia has risen from the ashes.

Dr. Eggman and Lex Luthor have formed a ruthless corporate alliance, combining their terrifying technologies to trap the Justice League and Team Sonic inside the void of Null Space. Neo-Metropolis is now a clinical, neon-lit totalitarian police state, heavily policed by automated security networks.

The alliance between the two megalomaniacs is on thin ice. While Lex Luthor commands the city through massive LexCorp mecha units and total network surveillance, Dr. Eggman is secretly planning a coup. Using the decrypted bio-data that Rouge stole from Luthor, Eggman is manufacturing the "Metal Legion"—a massive, automated army of robot duplicates built to copy the powers of the Legion of Doom.

Navigate a dangerous landscape of high-tech surveillance, mechanical combat, and imminent boardroom betrayal. Will you help the resistance free the heroes from Null Space, or side with the corporate tycoons to secure your place in the New World Order?
