Hello there! I am extremely excited because im quite the Metal Sonic fan and i absolutely love Shadow. What can i say.. im a sucker for Sonic clones. I noticed in your Encyclopedia entry for Metal Sonic, you state he is in Sonic Adventure 2. Is this true? I know for a fact he is in SA 2: Battle. Im dying to know!!! Thanks muchly -Steve
You unlock him by clearing all missions with A's as Shadow.
