Crystal Mountain Zone

Crystal Mountain is the fourth zone in Sonic Rivals. It is a wide mountain range covered in layers of thick ice with several traps, and is located on Onyx Island, a future version of Angel Island brought to the present by Eggman Nega.

Overview
The layout of Crystal Mountain Zone features several snovy peaks with frozen crags bluffs cutting through wide rock chasms, complete with icy rivers and stands up against a pink-colored, clouded sky. Many large multicolored crystals and sculptures made of frozen ice, along with large naked trees, frozen grottoes below the surface and hanging icicles decorates the course, which is completely covered in ice as well. It also cryogenic geysers in the outside blizzard.

Passing through Crystal Mountain Zones involves much vertical maneuvering, along with jumping out of the ice caves on ladders of springs or breaking through ice-walls, similar to them found in Holoska. Also, much like to the catapult on the Colosseum Highway Zone's course and in Holoska, this stages features a bobsled which can be used temporaily to proceed through this course, until a certain point.

This zone also features many traps and obstacles, all which are wintered themed. When passing through the frozen grottoes, the player can be damaged by spiky ice sculptures made of red and violet ice, and when hitting certain trees, it can cause frozen blocks of ice to fall down, thus blocking the path. This level also has a pit whereby the opponents can puch a boulder over any rival who falls into it.
