Sonic Riders: Zero Gravity (Playstation 2)

The fan-favorite Sonic Riders series returns with a whole new form of chaotic racing by manipulating gravity itself! These gravity-altering powers can transform walls into tracks, or create a "black hole" that sucks you through for the ultimate speed boost, and allows for an entirely new way to gain a leg up on your competitors. From illuminated highways in a bustling metropolis to the outer reaches of space, you will race at the speed of light on 16 dynamic courses.
