The world has fallen under the rule of LEGION, a supervillainous cabal of criminal masterminds. Doctor Babylon, LEGION’s head of technology and development, has unlocked the secrets of the cosmic power source Dark Matter and plans global armageddon. In the wake of LEGION’s ascendance, a crack-shot team of hand-picked agents known as MAYHEM emerges, whose sole purpose is to destroy LEGION and take the world back. Will you use LEGION’s Dark Matter-powered doomsday devices and super-weapons to wreak havoc on Seoul: The City of Tomorrow or will you join the band of gadget-wielding misfits to dish out some MAYHEM?
