Grand Metropolis

Grand Metropolis is the third level in Sonic Heroes, following the battle with the Egg Hawk. This futuristic city appears to be controlled by the monopolistic HEXAeco energy company, as a majority of the buildings and roadways are powered by them. Eggman has taken over the industry and is stealing their energy, so each of the teams sets out to release it from his control.

Additional Information

 * This level precedes the Power Plant, which is one of HEXAeco's facilities.
 * The HEXAeco slogan is "Clean Power, Clean Energy."
 * Team Chaotix's mission in this level is to defeat all of Eggman's robots. Since Eggman himself assigned them to do this, the city must have been a valuable asset for Metal Sonic.
