The game - Sonic & Tails 2 - Game Gear | GG

A wonderful continuation of the legendary Sonic Chaos.

Doctor Robotnik has captured all six Chaos Emeralds! Unfortunately for him, an accident during the testing phase of his incredible new weapon scattered the Emeralds across the island. While Sonic and Tails are looking for them, Eggman has already located the yellow emerald, and has convinced the Knuckles that Sonic and Knuckles are out because they want to steal the emeralds. Meanwhile, a cowardly treasure hunter named Sharpshooter Fang has begun his hunt for emeralds. This is going to be racing!
The game is considered the best after 2 parts of Sonic and Sonic Chaos.
