Crystal Frost Zone.

Crystal Frost Zone is a scrapped zone that would have appeared in the Sega Saturn cancelled video game, Sonic X-treme. It was supposed to be the fourth zone in Sonic X-treme. It was intended to be a winter/snow-themed zone for Sonic X-treme, but because the video game was never finished, Crystal Frost Zone was never finished. The zone appears to be similar to IceCap Zone from Sonic the Hedgehog 3. The mountains are colored blue and snow covers the place from inch to inch. Pine trees appear in Crystal Frost Zone, as well. Sonic the Hedgehog appears to be the only character playable for this zone according to the screenshot, but Tiara Boobowski could have been also playable as well.

Crystal Frost was going to have three acts: "Prism Chorus", "Cryogenesis" and "Icegates".
