Sonic X-treme should have been Sonic the Hedgehog's 3D debut on the Saturn, except it was cancelled in 1997. Diehard fans haven't given up on the game, though, and someone recently ported Sonic X-Treme onto modern PCs. The dream of Sonic X-treme will never die, it seems!
The news was announced on the Sonic Retro forums to much joy and celebration.
This is just the start. There's only one level in the current built, but they're hoping to add more.
However, We'd like to point out that this is a single level release.( More builds and levels to come later !)
We would also like you to know that this is an almost as is port of the engine (Almost as how the original developers had left it, A snapshot in time "if you will".
This first public release consists of a Jungle level, which I like to refer to as "The E3 Jade Gully level" since it was shown in one of the E3 96 Promo videos.
