Sonic learns that the cyber corruption may be linked to Infinite, who completely surrendered during the battle in Eggman Empire. Now… He's back again, this time with renewed power. And now he wants to completely destroy not only the Starfall Islands, but the entire world. Fortunately, Tails, Knuckles and Amy have teamed up with Sonic, and now they are ready to stop Infinite. Besides Infinite and saving the world, they still have to save Sonic's friends, who were also attacked by the Cyber Corruption.
