What starts as a friendly competition between Sonic and Knuckles quickly gets intense as other rivals jump in to take on Sonic. In heated head-to-head races, Sonic and his opponent trip, shove, and vault over each other using boost moves and power ups while hurtling toward the finish line at breakneck speeds. Players will negotiate wildly twisting 3D tracks and narrowly avoid hazardous traps while watching out for the insidious Dr. Eggman and his myriad of contraptions. Whether playing alone or against a friend, it's always a two-player experience with new, innovative gameplay mechanics supporting the high-spirited race!
