The Sonic The Hedgehog 2 Early Prototype, released to the public on Nov. 7, 2006, is a prototype of Sonic the Hedgehog 2 for the Sega Mega Drive/Genesis, which features extremely unfinished zones. This cart, seen in two 1992 episodes of Nick Arcade, predates the more famous Sonic 2 Beta. It was found and sold to drx in cartridge form for $1500 via a community effort.
In this version, only one zone can be normally played : Emerald Hill Zone. The rest of the Zones can be played only through a Level Select code. The level select screen is completely identical to Sonic 1's, and even contains the original Green Hill Zone.
Various tidbits:
- If Sonic runs into a wall with a high velocity, he will bounce back off of the wall. This feature was ultimately canned, but it uses unused sprites that remained in the later beta.
- Green Hill Zone and Labyrinth Zone are both included in the game, but have heavily corrupted tiles. They otherwise play similarly to their original forms.
- Hidden Palace Act 2 has some leftover object placement from Green Hill Zone Act 2. There is a third act, as well, which has water that constantly rises and falls.
- Each Zone uses music from Sonic 1, further proving that Sonic 2 was built off of Sonic 1.
- There is a Hidden Palace Act 3, which has water at a constantly rising and falling rate.
Art Differences
- Sonic and Tails are in different symmetrical designs on the end signpost
