Sonic Adventure 2 & Battle (2001) Music
After discovering the existence of a secret weapon mentioned in the diary of his grandfather, Gerald Robotnik, Dr. Eggman infiltrates a high-security G.U.N. facility in search of it. This "weapon", a black hedgehog named Shadow who claims that he is the "Ultimate Life Form", offers to help Eggman take over the world, telling him to rendezvous with him at the abandoned Space Colony ARK with more Chaos Emeralds. In this adventure, you play as Sonic, Tails, or Knuckles and attempt to save the world -- or play as Shadow, Dr. Eggman, or Rouge and conquer all who stand in your way.
