Asteroid Coaster

Asteroid Coaster is the sixth stage of Sonic Colors. . It takes place in an asteroid field with toxic green acid pools and several gravity-defying sections.

As the name suggests, much of Asteroid Coaster takes place on a roller coaster. The coaster has a prehistoric theme, with the track made from bone-shaped pieces, and various fossils decorating the surrounding asteroids.The Purple Wisp is unlocked by completing act 1.

The boss of this stage is similar but harder than Starlight Carnival's boss, a large armed spaceship. Additions include asteroids that Sonic must dodge.

Inside some of the asteroids are what appear to be industrial areas, with capsules (not Wisp Capsules) and machinery.

Trivia
The Asteroid Coaster planet looks similiar to Caterkiller.
