In order to steal six Chaos Emeralds, Dr. Ivo Robotnik traps the animals from South Island in robots. The player controls Sonic, whose goal is to free the animals and retrieve the emeralds. If the player collects them all, the game will have a good ending. If the player does not succeed, the bad ending will show Robotnik keeping the emeralds for himself.
