Sonic the Hedgehog 3

Sonic and Tails are back for another adventure as they again battle the evil Dr. Eggman (aka Dr. Robotnik), who is desperately trying to collect all the Chaos Emeralds to rebuild his Death Egg. Our heroes must again find the Chaos Emeralds before Dr. Eggman does, but winning the race won't be easy this time - a new adversary, Knuckles the Echidna, has arrived on the scene and will do whatever he can to keep Sonic and Tails from reaching their goal. Grab all the golden rings, find various bonus zones and overcome Knuckles and Dr. Eggman as you rocket through the third chapter in Sonic's adventures.
