Eggman takes over a few cities on Mobius with his large robot army and declares that he has made a machine that would allow him to control the power of chaos for all time. Sonic and his friends along with many more mobians had risen against this threat.

Their efforts succeeded against the army and they made it to Eggman's final fortress. Sonic told his friends and allies that he would go it alone from there onward. Tails gave him a bomb that would overload the systems of the machine and a belt that contained a pack on the side that had power rings that when used would be replenished over a certain amount of time.

With these two items and a wristwatch, Sonic entered the final area. What happens next? Find out now!
