Plot

About 4,000 years ago, a sentient weapon called the Gizoid was created by an ancient civilization. After being lost for millennia, the Gizoid was unearthed and researched by Prof. Gerald Robotnik. It remained dormant for another half century before being discovered by Gerald's grandson, Dr. Eggman. Frustrated at his inability to get the dormant Gizoid to work properly, Eggman abandoned the Gizoid at Emerald Beach, where it was discovered by Sonic the Hedgehog.

Sonic Adventure 2 (ソニックアドベンチャー2(ツー), Sonikku Adobenchā Tsū) is a 2001 video game developed by Sonic Team USA and published by Sega for the Dreamcast as part of the Sonic the Hedgehog series. It was released as the last Sonic game for a Sega console after the company decided to leave the console hardware business. A port for the Nintendo GameCube, Sonic Adventure 2 Battle, was first released in Japan in December 2001, with new content. The game was later released digitally for the PlayStation 3, Xbox 360, and Microsoft Windows in 2012.

The sequel to Sonic Adventure, Adventure 2 features two good-vs.-evil stories: a hero story of Sonic the Hedgehog, Miles "Tails" Prower and Knuckles the Echidna as they attempt to save the world, and a dark story following Shadow the Hedgehog, Doctor Eggman and Rouge the Bat in their attempt to conquer it. The stories are divided into three gameplay styles: traditional, fast-paced platforming for Sonic and Shadow; multi-directional shooting for Tails and Eggman, and action-exploration for Knuckles and Rouge. The game also includes an extensive Chao-raising system.
