Story
Set 1 year after Episode II, Sonic and Tails learn that Eggman has dissapeared from Tail's Tornado radar, and find this suspicious. Sonic and Tails eventually locate Eggman's wereabouts, and realize he has taken a cruise ship out to sea. After fighting his robots on a motorboat, Sonic and Tails arrive on the S.S Eggliner, and fight Eggman's new machine, the Octo-Egg, a machine that attacks like that of an octopus.

Defeating the Octo-Egg, Eggman abandons his cruise ship, and escapes the sights of Sonic and Tails. Tails eventually runs out of gasoline for the Tornado, and takes dock on a strange island, known as Volcanic Palace Zone, an underground Palace, made by an unknown person. The palace has been pushed up by the Volcano over the years, and at this point, is near to being covered in boiling lava. Sonic and Tails run through the flaming palace to find a big surprize in their way. Silver Sonic is mining the Super Emerald, and notices the duo, beginning to flee. However, the Volcano blasts the 3 out of the Palace, and straight towards the top of the Volcano. Defeating Silver Sonic while standing on a flying peice of crust, Sonic and Tails attempt a go for the Super Emerald, but Silver Sonic grabs the Emerald, fleeing towards the ocean.

Finally reaching land, Sonic and Tails reach a Construction site, otherwise known as Constructional Ilusion zone. Fighting their way through many puzzles, riddles, and mazes, they run into Dr. Eggman and Silver Sonic, who posses the Master Emerald in their hands. Dr. Eggman and Silver Sonic suck energy of the Master Emerald, and use it to twist up the construction objects to join together, forming the Metal Golem. Nearly getting killed, Sonic and Tails defeat the Egg Golem, and watch as Eggman escapes with the Robotic Hedgehog. Knuckles then arrives, surprized to see Sonic and Tails alive. Telling them he wishes to get back the Chaos Emerald, he joins forces with Tails and Sonic, ready to defeat Dr. Eggman and Silver Sonic.

Taking to the sky's, the duo arrive on the Egg Fleet, otherwise known as the Metal Fleet Zone. Zooming through the tons of ships, blasting through the interiors, and escaping an exploding array of battleships, Sonic and Tails encounter Silver Sonic, ready to man the ultamite ship of all, the Whale Ship. Using the Master Emerald, Silver Sonic makes the Whale Ship a portable nuke, and shoots a giant laser out of the front, destroying the ship Sonic and Tails are on. Having unlimited flight, Sonic and Tails must fly and hit The Whale Ship, simular to the Marble Hill Zone's Final Boss. Defeating him once again, Silver Sonic flees, while Sonic and Tails follow.
