STORY

Dr. Eggman is furious about the destruction of his Death Egg and the defeat of Mecha Sonic. He then decides that he will build a new and improved Mecha Sonic 2.0 from the scraps that were left in the ruins of Sky Sanctuary to help with his latest plans. After being caught abducting Flickies, Sonic and Tails catch up with Eggman, only to have the new Mecha appear and thwart their rescue mission. After getting Sonic and Tails off his back for now, Eggman gets to work on his new fortress code named: Project RAIDEN. To get it powered as soon as possible, he'll need the help of the 7 chaos emeralds, as well as support from Mecha Sonic and his new army of badniks. Meanwhile, Knuckles catches some Egg Robos causing mayhem again on Angel Island, collecting and abducting Flickies, and turning them into badniks. Knowing Eggman has something to do with this, he sets off to find out what evil scheme he's planning. He meets up with Sonic & Tails, and learn that they too are after Eggman, and team up once again on a new quest to save the island and put an end to his evil plans once and for all!
