After series villain Doctor Eggman releases an ancient monster, protagonist Sonic the Hedgehog vows to stop him collecting the Chaos Emeralds. The other playable characters are flying fox Miles "Tails" Prower, love interest Amy Rose, Knuckles the Echidna, who plans to reassemble the Master Emerald, angler Big the Cat, and E-102 Gamma, one of Eggman's robots.

A sequel, Sonic Adventure 2, was released in 2001 for the Dreamcast. Enhanced ports of the game were released in 2003 for the Nintendo GameCube and Microsoft Windows. It has since been re-released as a downloadable game for Xbox 360 via Xbox Live Arcade, and PlayStation 3 via PlayStation Network in 2010.
