Sega released more Sonic Riders screenshots, showing hot “Turbulence” and “Turbo” action. The new game, developed by Sonic Team from Tokyo for the PS2, Xbox and GameCube, features Sonic and friends being challenged to a Worldwide Grand Prix by Dr. Eggman. They must glide on air boards, performing tricks and stunts over wide-open terrain. Sonic Riders will be available this February.
