Professor Gaezebo Boobowski and his daughter, a hedgehog named Tiara, are masters of the art of Ring Smithing and are the guardians of the six Rings of Order. One day they learn that someone is after their Rings. You guessed it: Robotnik. They call on Sonic and ask for his help in gathering the rings before Robotnik. Sonic gladly excepts the requests and begins his search, preparing for the dangers ahead.
Sonic X-Treme was supposed to be Sonic's big debut on the Saturn, slated for a Christmas '96 release, but it was pushed back due to SEGA's inability to meet the deadline. The new release date was March '97, but things just didn't work out with the game, and it was scrapped.
The game, as you can see from the screenshot above, was supposed to be a state-of-the-art 3D game like Bug!, but you could roam freely in a total three-dimensional enviroment instead of being confined to paths. Another feature of the game was the new moves Sonic had, including the Spin Slash, Power Ball, and an interesting one, Ring Throwing.
I personally hated to see the game go. It looked like it was going to be a great game. In fact, this was one of the reasons I bought my Saturn was to play this game. Then it gets scrapped a few months after I buy it! I feel like I was ripped off now 'cause I bought the Saturn for nothing.
But maybe it was the right thing to do, as looks can be deceiving. The playable demo at E3 '96 got negative reviews, and those who played it were not impressed with how it was shaping up. What was wrong with it? Maybe the wrap-around camera angles were too much to bear, or the controls were choppy, or the graphics were bad. We may never know.
