Sonic Chaos

After Sonic 2 for gamegear Came Sonic Chaos which story is and I quote. The storyline to Sonic Chaos revolves around Dr. Robotnik and his quest for world domination via the use of the mysterious Chaos Emeralds to create nuclear weapons and lasers (according to the North American instruction manual).

While out on an aimless adventure, Sonic and Tails hear a troubling rumor: word has it that Dr. Eggman has returned to South Island in their absence and has managed to procure one of the Chaos Emeralds. As a result of the theft, the other five Emeralds have been thrown off-balance, scattered to all ends of the island. Without the power of all six Chaos Emeralds, South Island and its residents will sink into the ocean. With no time to lose, Sonic and Tails head for ground zero to retrieve the stolen gem. Robotnik has stolen the Red Chaos Emerald, causing the other emeralds to "lose balance" and be transported to a parallel universe. As a result, South Island is now sinking into the ocean, and it is up to Sonic and Tails to save the island and foil Robotnik's plans of world domination. It is also a very short game as these videos will show. That is a bad thing
