Shadow the Hedgehog
|Number of acts||
Shadow arrives at Circus Park searching for the fourth Chaos Emerald. As he approaches the carnival, he spots Tails flying overhead in the Emerald-powered Tornado 3. For an unknown reason, Tails crashes his plane (the fox is most likely shot down in the crossfire between Eggman's defenses and an attacking force of G.U.N. troops, bailing out and leaving the Tornado to spiral away into the distance), and it is later revealed that he came to retrieve the rings that Dr. Eggman had stolen. Undaunted by his violent arrival, Tails suggests to Shadow that they should team up and recover all the rings Eggman has collected in the park. Further in the level, Shadow runs into Eggman's Drone, who conversely asks Shadow for his help in defeating the "G.U.N. geeks". The player can choose to help Tails recover the rings, eliminate the G.U.N. robots, or simply find the gray Chaos Emerald.
Eliminate the G.U.N. Beetles!
- Guide: Doctor Eggman
- Objective: Defeat all 20 of the G.U.N. enemies in Circus Park.
- Tips:Many of the G.U.N. Beetles are off the beaten path, so you may need to explore to find some. Four should have been defeated by the time you reach checkpoint #2, 10 by checkpoint #3, 13 by checkpoint #4, and 15 by checkpoint #5. The last five lie after checkpoint #5.

Collect 400 Rings!
- Guide: Tails
- Objective: Gather 400 Rings.
- Tips: Although initially there are not actually 400 Rings in the level, there are special ways to earn bonus rings. These include:
- Shooting Gallery - To begin, shoot one of the large disks that looks like a clock. Balloons will then rise around Shadow, which he must shoot to earn rings. There is also a green bonus gauge which fills as balloons are hit; filling it completely earns Shadow an extra 50 rings. Shooting purple balloons, however, causes the gauge to decrease and Shadow to lose rings.
- Being launched into a nose that looks like Eggman - This becomes very helpful, when approaching one of these "noses" and later, the checkpoint after it. Use it to travel back to the checkpoint before the "nose", then replay it. Shadow will get 50 rings each time.
- Flaming Hoops - Jumping through a flaming hoop earns Shadow 5 rings.
|A||≥ 26,000 points|
|E||< 10,000 points|
