Metal City

"Massive skyscrapers and fast cars populate this futuristic city, home to a course famous from the first Grand Prix."

- Course description, Sonic Free Riders

Metal City is the first course in Sonic Riders, and returns as the last course from Sonic Free Riders.

Story
The game starts out with Sonic, Tails, and Knuckles tracking a Chaos Emerald. They soon find out it has been stolen by a group of thieves riding hoverboards. Sonic tries to stop them, but they simply go around him. Knuckles manages to knock one off his board, but he hitches a ride with one of the others. Tails spots a strange marking on the board, but then Sonic ignores him, takes the board and gives chase. He soon catches up with their leader, but as Sonic cuts in front of him, the mysterious thief attacks him from above and knocks Sonic off. He mutters "So you're supposed to be the fastest thing alive?" before escaping.

The next day, Sonic and friends find out that Eggman is hosting the EX World Grand Prix, a tournament for Extreme Gear. What's more, is the mysterious thieves from the night before are competing. So Sonic and friends decide to enter to find out what Eggman is up to, and who these thieves are.

Overview
The stage takes place at day time, the city also called "Future City." There are many 'future' cars that must be avoided unless you are a Power Type Character. Everything in the city is metal, and all metal streets have 'future' buildings. There are three grinding rails for speed type, two air ride links for flying type, and outnumbered obstacles to smash for the power type. The stage in Story Mode is only playable as Sonic, but in a normal race, any character is available.

There is also a Babylon story version of this course (for Jet the Hawk in story mode), called "Night Chase".

In Sonic Free Riders, the Metal City is the last stage. The stage gets unlocked by clearing the Last Story scenario and has two difficulty modes: standard and expert. This stage is also used as the setting of Tutorial lessons of the game.
