Sonic Adventure 2 Battle

Sonic Adventure 2 is a platform game developed by Sonic Team and published by Sega for the Dreamcast video game console. It was released in North America on June 19, 2001 and in Japan on June 23, 2001 to mark the 10th anniversary of the release of the first Sonic the Hedgehog game. It is the sequel to Sonic Adventure. It is the seventh chronological installment in the Sonic the Hedgehog series and the last to be released for the Sega platform. It follows the protagonist team of Sonic the Hedgehog, Knuckles the Echidna, and Miles "Tails" Prower and the antagonist team of Doctor Eggman, Shadow the Hedgehog, and Rouge the Bat and their attempt to work together in order to save the world from destruction.

The game was a commercial and critical success, receiving generally positive reviews; however, criticism was directed towards its camera system and side characters. Due to Sega's exit from the video game console manufacturing business, the game was ported to the Nintendo GameCube and re-titled Sonic Adventure 2: Battle, with brand-new features as well as minor changes in the level design. Battle received mixed to positive reviews from critics, who praised its new features and ability to use the GameBoy Advance link cable; however, reception was generally less positive than it was for the original Dreamcast release. Despite its mixed reception, Battle was a commercial success, selling more than 1 million copies worldwide and becoming the tenth best-selling Nintendo GameCube game of all time.
