Sunset Hill

Sunset Hill is the second zone of Sonic Advance 3. It is heavily based on the first level of Sonic the Hedgehog, Green Hill Zone, but with a dusk type setting, complete with palm trees and checkered soil. The music is a remix of Green Hill Zone's theme.

Unique features here include waterslides, tall segmented springs that recoil the player a short horizontal distance, and vertical poles which the player can slide down and jump off of to either side using the jump button and the D-pad. There are also large, slow-moving floating platforms that can either assist you in navigating the stage or crush you, resulting in an instant death. Act 1 introduces water mechanics to Sonic Advance 3.

This zone ends with a boss fight against Gemerl in Act 3. If this act is completed with Sonic in the lead (although at this point, the only other possible combination would be Tails-Sonic), a cutscene will play. It will feature Sonic and Tails meeting Knuckles, who expresses his desire to support whatever are they doing, to what Sonic just says that they won't need any help by now. Knuckles, even angry at this, is unlocked for the main game and time attack modes.

Boss: Egg Wheel
The Boss Fight takes place in a circular arena. Dr. Eggman and Gemerl will appear in a large wheel which comes rolling down the right-hand side of the arena. Eggman will laugh and then continue rolling-from this point on you are vulnerable. Tails is the best at defeating this boss-aside from Cream, of course. A large button activates a floating platform in the centre of the arena. Eggman doesn't really have any tactics here- but he doesn't need to, seeing as his contraption is invincible! Well, almost. The weak point is the usual place (his head) but the fact that he is constantly rolling is a problem.

During the initial phase, it is possible to strike Eggman without losing any rings (you'll need them for the pinch) - just hit The Doctor when he comes rolling towards you at the bottom of the arena, he vwon't be moving too fast. You can always fly with Tails and use the platform- but you'll probably lose rings. During the Pinch, it's nearly impossible to strike Eggman at all, he's moving so fast. All you can do is jump when he comes towards you and hope you hit him, then collect any rings that you can. To speed things up, have the platform ready,and just after you've hit him (if you've any rings left) jump up with/as Tails and fly up to Eggman. Wait till you get a chance to hit him (which won't take long) and bash him in the face! If you don't mind losing all your rings, seeing as they don't matter in the end anyway, the Egg Wheel can be defeated and the Star-Ring collected in 30 seconds.
