Sonic Adventure 2: Battle

Sonic and company are back and better than ever in Sonic Adventure 2: Battle. Dr. Eggman is causing trouble once again, and it's up to Sonic, Tails, and Knuckles to stop him. Experience faster action, all-new two-player games, and a branching storyline that lets you choose to save the world as the Hero side, or conquer it as the Dark side. In the single-player mode, you'll go through more than 30 unique stages, which include a forgotten pyramid, an abandoned military base, and a giant space station.
