A limited, rough playable build of the Sonic Crackers prototype leaked onto the internet in 1996. [256] [257] [258] [259]	Sega	Sega
Sonic X-treme	A proposed Sonic the Hedgehog game by Sega Technical Institute while Sonic Team was busy developing Nights Into Dreams for the Sega Saturn. The game featured a troubled development history, with multiple platform changes, as Sega struggled to figure out which direction to take the franchise after Sonic & Knuckles (1994). The earliest planning began as another side-scrolling platformer on the Sega Genesis, but as ideas moved into making the game a 3D platformer, and the team quickly transitioned to the more powerful 32X hardware, where it was temporarily known as Sonic Mars , and then transitioned again to the Sega Saturn, which was worked on until its ultimate cancellation in late 1996.
