Split-up into teams, Sonic, Sally, Antoine, Bunnie and Rotor are forced to flee Robotropolis in mid-plot. Their rendezvous is a train station, where Sonic's roboticized Uncle Chuck boards a departing train. The Freedom Fighters follow the train to the crystal mine to try to rescue him. Unsurprisingly, he is not the hedgehog he used to be, but Sonic temporarily fixes that with a power ring. Returning to Knothole with the freed Uncle Chuck will have to wait, however. The robots are excavating a powerful crystal, which will further Dr. Robotnik's goals and wreak havoc across Mobius. Can the Freedom Fighters stop this plot? And can Uncle Chuck truly be saved?moreless
