Sonic Adventure 2: Battle allows you to take control of both the mammalian protagonists we all know and love, and the antagonists we feared as children across two campaigns: Hero and Dark, in which players battle to save and conquer the world respectively.
Play as Sonic or Shadow across fast-paced levels which focus on platforms and gameplay, take control of Tails or Dr. Eggman and experience slow directional-shooting zones within mechs and explore an open world and hunt treasure with Knuckles or Rouge.
