Sonic Riders finds the iconic hedgehog taking a breather from his platform exploits and engaging in high-speed air board races with 16 of his beastly buddies. Dr. Eggman plays host to an intergalactic tournament spanning 14 tracks, from the industrial Metal City to the tropical Splash Canyon, each filled with ramps, rails, tunnels, alternate routes, and plenty of gold rings. Sonic and close friends Tails, Knuckles, Amy Rose, and Cream the Rabbit must defeat Eggman's dream team of riders, known collectively as the Babylon Rogues. Characters are individually rated in speed, power, and flight, while over 30 types of ability-enhancing equipment are available to further customize riders. <br><br>As in traditional skateboard and snowboard titles, players can perform a number of grabs, spins, and other tricks, but the air boards have the added ability to create turbulence, which players can strategically use to draft behind their rivals. Another feature of the game is an air meter, which is filled by performing tricks and unleashing massive jumps. Players can use the stockpiled air at any time during the competition for more precise cornering, a speed boost, or to create a tornado to temporarily stun pursuing rivals. Up to four speed demons can compete in racing, battle, and tag modes, with the latter supporting cooperative play.
