New gravity-altering powers can transform walls into tracks, or create a "black hole" that sucks players 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, race at the speed of light on 16 dynamic courses. Vehicles with over 40 upgrades allow you to grind rails and pull off daring tricks on futuristic tracks, including solar loop-de-loops, height-defying vertical drops and tonnes of other edge-of-your-seat moves. As Sonic or one of 18 colourful characters, players will compete with up to three friends at heart-stopping speeds in three exciting multiplayer modes. With all the action, speed, and addictive gameplay that only Sonic can deliver, Sonic Riders: Zero Gravity is set for hyper-drive!
