Sonic detonates several land mines on the outskirts of Robotropolis so the Freedom Fighters can locate one of Robotnik's power cables and steal power for Freedom HQ. They find two identical cables and have to choose one to take. The one they choose turns out to be booby-trapped, leaving them imprisoned inside a giant force field dome with an army of SWATbots closing in.
