Dr. Eggman challenges Sonic and his friends to a Worldwide Grand Prix, and the prize for coming out on top is an ultra-rare Chaos Emerald! Gliding on air boards – which are performance-oriented for each playable character – gamers will experience a heightened sense of sports-style racing tension as Sonic Riders characters perform tricks and stunts over treacherous wide-open terrain.
Gamers control Sonic and friends speed through tracks on air boards, using individual special moves to strike down opponents. Air is a big element of Sonic Riders . Your board's "fuel" source is air. You can fill up your air at various points on the course, but to race well you'll have to use another means of replenishment: performing tricks with your board. You'll also want to make use of turbulence from racers who are in front of you.
Sonic Riders was released for the Playstation 2 on March 17th, 2006.
