Aquatic Capital is the fourth course from the Heroes story in Sonic Riders: Zero Gravity. Aquatic Capital is a city lying in the vicinity of Monopole, next to Dr. Eggman's MeteoTech Premises. It gets its name from its location and the fact that there is water everywhere. This race course features more wall-to-wall gravity power.
In the story mode, Amy is being chased by Storm because he wants the Ark of the Cosmos that Amy has. Sonic, Tails, and Knuckles must race against the clock (the time limit is 3:24:00) to get to Amy before Storm does.
The race takes place in a futuristic city resembling a waterworld. Gondolas appear frequently in the race.
Near the end of the course, there is a giant fountain, which the player can pass through by flying.
Musical ThemesEditThe music played in this level is entitled "Aquatic Time". It resembles the music for Empire City's daytime stage in Sonic Unleashed.
