For content that appeared in the original game, see Sonic Adventure 2 (Dreamcast).
This page lists unused content exclusive to (or that first appeared in) the Battle version. One thing it didn't fix was the cut-off dialogue. It's merely a port of Sonic Adventure 2, which stays true to its predecessor while providing new features such as an expanded two-player mode and, for the most part, upgraded graphics. Sonic Adventure 2: Battle was the first Sonic game for the GameCube, as well as the first official Sonic game on a Nintendo console. This game has unused playable characters.
