Shadow the hedgehog is dead. DEAD As in D.E.A.D. Sonic's gone insane,unleashing Dark Sonic. It's happened before, but not this bad. He's going on a killing spree, murdering anything that crosses his path, including his friends. Only one person can stop him, but he's gone. How are Sonic's friends going to stop him when the only person that can keep him sane is dead?
