Central City

Central City is a fictional capital city of the world-controlling government in the Sonic the Hedgehog series of video games.

Sonic Adventure 2
The city in Sonic Adventure 2 is unnamed, but said by many to be San Francisco or Station Square. The first Hero cutscene states that it takes place "above the capital city", and in Shadow the Hedgehog, GUN soldiers and Doom's Eye refer to Central City as the capital. This concludes that the city in Sonic Adventure 2 is most likely Central City.

Areas

 * City Escape, a stage based on the long slopes of San Francisco. Sonic runs through the stage while escaping from GUN.
 * Radical Highway, a highway bridge under construction based on the Golden Gate Bridge.
 * Mission Street, a street stage that is also set on the bridge at times.
 * Route 101, a long bridge over an ocean. Miles "Tails" Prower drives on it while chasing the President.
 * Route 280, an equally long bridge, where Rouge the Bat chases Tails. However unlike Roure 101 this route is more lethal as there are large holes.

Sonic Battle
Central City appears as an overworld in Sonic Battle. In it, there's an apartment where Amy Rose and Cream the Rabbit live, a skyscraper with a library and a famous database, and a highway called Battle Highway. Tails goes to here to find out more about Emerl. Another part of Central City named "Night Babylon" also appears, as a casino district where Rouge owns her own club and Dr. Eggman has one of his numerous bases.

Shadow the Hedgehog
Central City makes its latest appearance in Shadow the Hedgehog. The first city appearing in the game is named Westopolis, but if Shadow helps Eggman light five lanterns in his Cryptic Castle base, Shadow goes to the Central City stage. In it, GUN tries to fight off the invading Black Arms aliens that are trying to destroy the city. The Hero Mission is to help Knuckles the Echidna capture twenty bombs, and the Dark Mission is to help Black Doom detonate five giant bombs. Shadow the Hedgehog reveals that the President of the "United Federation" nation lives in Central City in a variant of the White House. It is destroyed by the Eclipse Cannon after clearing the Dark Mission of The ARK stage. Whether Central City is destroyed or not is up to the player, but canonically it happened. Central City also appears in Expert Mode, where Espio the Chameleon challenges Shadow.
