Sonic 3 Prototype

A prototype version of Sonic 3, containing features that would never make it into the final build, has been discovered.

Now you can play it online.

The prototype of Sonic 3 that contains a variety of elements that were reported in a 1993 magazine preview, but never seen in the retail release. These include the Flying Battery zone and bosses (which were moved across to Sonic & Knuckles), and Lava Reef. Also found in the ROM are three unfinished bonus stages, and object, badniks, and boss data for cut zones.

As Always, Good Luck and Have Fun.
