Sonic Advance 3
Route 99 (ルート99 Rūto 99?) is the first Zone in Sonic Advance 3. It is a highly urbanized area and one of the parts of the earth that Dr. Eggman created when he broke the planet apart with Chaos Control.
The boss here starts off with a fight with Gemerl. To defeat him, the player needs to hit him four/two times. Then the characters are escorted to fight with the Egg Hammer 3. To defeat it, the player will need to know when he's going to hit the player. The hammer will smash left and right alternatively. When Dr. Eggman smashes down, the player needs to smash his face in. The player needs to hit him eight/six times for him to be destroyed.
- The city background of this level appears to be based on a pre-2001 Lower Manhattan as a skyscraper that resembles the North Tower of the former World Trade Center complex (as well as other buildings that resemble the surrounding World Financial Center) can be seen amongst the skyline. The original building was destroyed in the 11 September attacks, nearly three years before the release of Sonic Advance 3.
- The music played in the level is a remix of Tails' Lab from Sonic Battle.
- The name of this zone could be a reference to the famous U.S. highway, Route 66.
