European & AmericanSave Floating Island!
The last time Sonic and Robotnik when head-to-head, Sonic blasted Robotnik's Death Egg to smithereens. The explosion heaved Sonic deep into Floating Island's Mushroom Hills!
Sonic knows that many Emeralds, including the Master Emerald, are hidden somewhere on Floating Island. He bets the Knuckles character knows where they are! Sonic can't let Robotnik get his hands on the Master Emerald. He'd have Death Egg fuel forever - and Floating Island would be destroyed!
Now Sonic's got two problems. How to protect the Master Emerald? And how to keep Knuckles off his back? He'll have to deal with that wild echidna right away!
Knuckles has problems, too. As Guardian of Floating Island and all the Emeralds, Knuckles has a mission - to wage war on all invaders. Whoever threw that bomb is in DEEP trouble. Knuckles is ready with tricks, traps and bare-fisted attacks to keep Floating Island sage.
Sonic's not taking any changes. Neither is Knuckles! But while they're going the rounds with each other, who's stopping Dr. Robotnik? Could this be the end of Floating Island?

JapaneseHaving had its relaunch interrupted by the efforts of Sonic and Tails (the events of Sonic 3), the Death Egg plummets back down onto the mysterious island from whence it came. The enormous aerial base crash lands, conveniently enough, on the peak of an active volcano. Sonic and Tails, meanwhile, land safely in a lush mushroom forest deep in the island's interior. Shortly after his descent to terra firma, Sonic notices the island's guardian and all-purpose troublemaker, Knuckles the Echidna, sneak out of a hidden thicket. Curiosity piqued, Sonic investigates the thicket and finds a giant, multi-coloured Super Ring. He leaps in and finds himself whisked away to a massive underground cavern. In the centre of the cavern lies an intricately detailed and remarkably well-preserved ruin: the Chaos Emerald altar. In the middle of the altar lies a humongous green jewel - none other than the Master Emerald, the legendary "stone of power" that destroyed the echidna civilization. As Sonic gazes in awe at the beautiful gem, the seven Chaos Emeralds are whisked from his grasp by an unseen force. The Emeralds oscillate violently in mid-air and, with a blinding flash, return to their pedestals around the Master Emerald.
The relentless Dr. Eggman, meanwhile, has once again evaded fate and is pleased to discover that the Death Egg is not too badly damaged. He has plans for one last ditch effort to get the machine back into operation, and that fabled Master Emerald should do the trick...
Knuckles is left with the task of rescuing the recovered Master Emerald from the relentless pursuit of a rogue Eggrobo (or perhaps several Eggrobos).
