In a simultaneous global assault, LEGION has taken control of the nations of the world and the only force left to stop them is MAYHEM. Led by the mysterious and no-nonsense Persephone Brimstone, MAYHEM's elite Super Agents are called to the city of Seoul, South Korea. Led by LEGION Minister Doctor Babylon and his diabolical lieutenants, a nefarious plot is set in motion to build a world-altering device that will grant unrivaled power to the supervillain organization. In order to stop LEGION and take back the world, the Agents of Mayhem will traverse a sprawling urban battlefield from the ground to the rooftops and team up as a super-agent collective to stop LEGION at any cost. Success is far from guaranteed and collateral damage will be substantial, but it's all in a day's work for the Agents.
