Background:
Dr. Eggman has used Chaos Control to break the world into 7 parts, and plans to rain confusion by turning each into a Dr. Eggman Empire. Sonic and Tails, having been separated from their friends, are teaming up to return the world to its original state. To do this, they must find all 7 Chaos Emeralds and use Chaos Control to undo Dr. Eggman's mischief. But Dr Eggman isn't resting on his laurels. He's used his engineering genius to perfect the ultimate fighting robot, and will do all in his power to stand in Sonic's way.

Gameplay:
Sonic is balanced as a fast and furious runner, which makes him prime to beat the game quickly with the minimum requirements. But since this design puts a lot more focus on exploration and discovery by hiding little "chao" creatures in strategic locations all over the map, it's impossible to see everything without playing through each level multiple times. Players can use Sonic and Tails to beat the entire game at 100% and finish all seven worlds.
