Sonic Rivals is a side-scrolling racing platformer where you compete against a rival character through each level instead of cooperating. Doctor Eggman's turned several characters into cards with a new device, prompting Sonic and Knuckles to chase him down separately—Knuckles refuses teamwork since the Master Emerald's at stake. Shadow gets pulled in after receiving a distress signal, while Silver arrives from the future to pursue the same target. The twist: the villain's actually Eggman Nega impersonating the real Eggman, who's already been turned into a card. Gameplay focuses on head-to-head races through themed zones, with power-ups and attacks to slow your opponent. Each character has their own story path that converges on the same reveal. It's built for players who want competitive Sonic rather than the usual solo speed runs.
