Can the fastest hedgehog in the known universe tackle the most deadly enemies yet? Lead Sonic through futuristic landscapes, lost islands, and into outer space in this sequel to the popular Sonic The Hedgehog. Hidden rooms and passageways will lead to enormous Zones, and a special stage allows you to collect obscured Chaos Emeralds, if you can avoid the hazardous 3D energy spheres, of course. Transform into Super Sonic, giving yourself the key to ultimate speed and power. As usual, the object of the game is to outsmart Dr. Robotnik, but this time the evil genius has some new tricks up his sleeve including the infamous Knuckles!
