Sonic Mars was a concept in development for the Sega 32X, which was later reworked into Sonic X-treme. The 32X version was cancelled, probably due to a combination of the add-on's limitations and also its ultimate failure in the marketplace.
Unlike most Sonic games, this one was based on the SatAM cartoon. This was also going to be the first 3D polygonal Sonic game. The SatAM theme was dropped eventually due to disinterest from the development Team.
In 2007, a early script of Sonic Mars by Micheal Kosaka was leaked. Interestingly enough, on the list of upcoming games are Sonic 3 + and Sonic Stadium. Another script was also leaked by Don Goddard. The cover page on the Micheal Kosaka script is dated May 19, 1994 and the Don Goddard scipt was created later.[1] Refer to the navigational template below for more information.
