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. Ricocheting about like a pinball, our furry little hero will hit bumpers, platforms, and more at breakneck speeds. The Power Sneakers are back, and the addition of a Super Spin Dash means the excitement will be fast and furious. 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? Play alone or challenge a friend.
