Sonic Rivals PSP

What starts as a friendly competition between Sonic and Knuckles quickly gets intense as other rivals jump into the action! Utilize boost moves and power-ups as Sonics rivals try to trip, shove, and vault over Sonic while hurtling towards the finish line at breakneck speed! Negotiate wildly twisting 3D tracks, avoid hazardous traps and hazards, and watch out for the insidious Dr. Eggman and his myriad of contraptions! Whether playing alone or against a friend, its always a two-player experience based on tightly designed gameplay mechanics to support high-spirited competition and ultra-tight races!
