Dr. Robotnik is plotting a takeover of the entire world, and Sonic is
going to have his paws full trying to stop him. Along with his newfound friend,
Tails the Fox, Sonic will speed through loop-de-loops, crazy mazes, and
dizzying speedways. Bounce like a pinball through the bumpers and springs of
the amazing Zones –all at break neck speed! There are seven Chaos Emeralds for
you to capture and tuck away; anything short of that will mean certain doom for
your friends and success for Robotnik. We wouldn't want that, would we?
