Sonic Riders: Zero Gravity
Crimson Crater is the final course in Sonic Riders: Zero Gravity's Heroes story. It is where Eggman's mother computer is located and where he plans to use the power of the Arks of the Cosmos to control all the world's robots. Sonic has to race Knuckles, Tails, Amy Rose, Jet, Storm and Wave to win the Arks of the Cosmos and save the world from Eggman.
The race takes place in a mechanized city, specifically in a tall metal tower in the center of the city, where Eggman's mother computer is located. The player starts off from a tall ramp. The stage is rather difficult, as it is the last stage of the Heroes Story.

- This course is set in the desert of the Sonic Riders course Sand Ruins because Babylon Garden is hanging above it as seen in some cutscenes.
