Storyline
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 Robotnik has returned to South Island in their absence and has managed to procure the Red Chaos Emerald. 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.
