Publisher: Sega
System(s): Sega Mega Drive/Genesis
Genre: 2D Platform

Sonic the Hedgehog 3C Prototype 0408 for the Sega Mega Drive/Genesis was released by drx during the February 23rd, 2008 proto release. A later in development beta with a compilation number of 0517 was also found. When this beta was obtained by drx the file was labeled 3C indicating this was a unreleased version of Sonic 3. Due to the late development date (dating after Sonic 3's release) it's obvious this isn't Sonic 3 before it was split into 2 games.

This is a prototype for the cancelled Sonic 3 and Sonic & Knuckles compilation called Sonic the Hedgehog 3 Limited Edition.

  • Sound test numbering is different for most sounds. Lots of empty slots for sounds in the sound tester.
  • If Lava Reef act 4 (Hidden Palace Zone) is accessed via Level Select it will use Sky Sanctuary music.
  • The echo track of Flying Battery Zone's Act 1 music will go off sync after two loops, and slowly gain drag behind the lead melody.

Level Differences

Doomsday Zone

Act 1

  • It has a really crappy layout and in some places you can see portions of the supposed background. In the final version, other background is implemented.
  • No Super form here. There's no Sprite glitch if you enter this level as Tails or Knuckles, unlike the final version.
  • If you begin this level without Debug mode, you'll instantly fall to death.
  • You simply can't go through the level.

Act 2

This level is very similar to the Act 1.

  • Death Egg's Act 2 music is played
  • You can see portions of the boss present in the final version.
  • You can't go through the level as it is in a very early development stage.
  • You can enter the levels with Tails if you selected him.
