The industrial theme is a stage theme that appears in the Sonic the Hedgehog series.
Most industrial stages take place within factories or facilities, usually belonging to organizations such as the Eggman Empire, G.U.N. or another party/organization. As such, most of these stages are among the last few levels in practically every game.
It is most often incorporated with the space or urban themes, given that most space themes take place on space stations. Elements common among industrial stages include conveyor belts, electrical hazards, and buzzsaws. See: Industrial gimmicks.
