Chapter 1: "Insuar Island Base"

After escaping Death E.G.G Zone (see Sonic the Hedgehog 4: Episode III), Dr. Eggman flys to Insuar Island where he decides to revive Sliver Sonic II. Nearby, Sonic and Tails are relaxing on Cocoa Island (one of Tails' favorite vacationing spots) when Tails' Chaos Energy detector detects Chaos Energy coming from Insuar Island. Sonic suspects Eggman is behind it. Just then, Knuckles and Shadow arrive. Shadow tells Sonic that he was sensing massive amounts of Chaos Energy coming from Insuar Island. Tails tells them that's the case with his Chaos Energy detector. They jump on the Tornado IV and set off. Meanwhile, at Eggman's base, Sliver Sonic has been revived and is practicing his moves for the coming fight with Sonic. Little does Eggman know that Sonic has friends. He sends out his new Badniks to guard the rest of the island while he finishes the Death Egg Mark. 3.

Chapter 2: "Rumble in the Ruins"

Eggman retreats back to his base, but Sonic and his friends need to spilt up to find his base. Sonic heads out with Shadow, while Knuckles heads out with Tails. Along the way, Sonic encounters some Elecapes and Fullboars, who spot Sonic and Shadow and attack them. Shadow manages to escape, but Sonic is captured. Tails and Knuckles meet up with Shadow in front of a large temple. Shadow tells them that Sonic was captured by some Badniks. Tails says no good can come from this. They head back towards the minor ruins to find Sonic. You play as Tails and the others, but after you rescue Sonic, you can play as him.
