Ah, Sonic Xtreme, arguably one of the most infamous games that never came to be. Despite this, both fans and even the original staff that worked on the game have for years been documenting it’s development history from it’s gameplay concepts to it’s plot, and everything in between.

Today, new Sonic Xtreme concept material has surfaced via a YouTube channel called RDPH Games, with several videos showing never before seen prototype material. Notably this highlights some aspects of Sonic Xtreme before it was a SEGA Saturn title, back when it was still being conceptualized as a game for the failed 32X add-on. These videos include a running animation clip that according to the description was made hours before a meeting with SEGA of Japan, an animation test with a possible title screen for “Sonic 32X”, and a mock up of a hypothetical bonus stage.

While at first glance these clips may not seem significant, every bit of information helps shed some more light of what happened behind the scenes when it came to Sonic Xtreme. In this case, seeing more of Sonic Xtreme before it’s jump on the SEGA Saturn, along with general never-before-seen clips.
