The Sonic the Hedgehog prototype is an early build of Sonic's debut game, and extremely incomplete. Many stages cannot be completed due to the lack of signposts and bosses; some (like Clock Work Zone Act 3 and Final Zone) haven't been started at all, or are obvious placeholder designs (like the Special Stage).
