Radical Highway

Radical Highway is a stage from Sonic Adventure 2, which is Shadow's first stage in the game's Dark Story. The level takes place in an area that resembles San Fransisco's Golden Gate. The opening cutscene of Sonic Adventure 2 also takes place here. The stage bears similarites with Speed Highway from Sonic Adventure. The stage was remade for the 3DS version of Sonic Generations, representing Sonic Adventure 2 in the Dreamcast Era. In the console version, City Escape represents Sonic Adventure 2 instead.

In M.U.G.E.N., Radical Highway has been made by Emerald.

Emerald's version
Emerald's version is a 2D rendition of Radical Highway converted to M.U.G.E.N. The stage does not feature any animations. The stages is about two screens wide and the camera pans upward when a Super Jump is used. Notably, the music used comes from Sonic X rather than Sonic Adventure 2.
