Super Sonic Adventure - Sky Deck

Dr. Robotnik's flying fortress is enormous and fully loaded with all things cool! ...but; Super Sonic is overpowered; as such, the Egg Carriers existence is invalid.

Originaly, Super Sonic was meant to be playable in regular stages; but its concept got scraped later in development.
Chances are, it probably wasn't meant to be played like this, at all; but, given that there is no such thing as an availavble prototype containing Super Sonic data, meant for regular stages; this mod/cheat of sorts, is the closest we'll ever get to experience gold man in normal levels.
