First time ever shown
For the first time ever, footage of the Point of View developed version of Sonic X-treme is being shown publicly, running on Sega Saturn hardware to boot. This build is going to be released for download on May 6, so if you’ve been hankering to play a kind-of-functional version of Sonic X-treme your chance is almost here.
The history of Sonic X-treme involves different iterations of the game being worked on by multiple developers before it was finally cancelled by Sega. Other early builds have been leaked to the internet, along with screenshots and videos of various work-in-progress versions.
