Somewhere in North Amareica, there is a city that can't be found on any map called "Canterlot City," but everyone just calls it Canterlot.

The two hottest things in Canterlot City are the punks wearing magnetically driven in-line skates powered by newly developed "netrium" batteries and "Jet Set Rodeo," a pirate radio station manned by the DJ "PON-3," that plays nothing but non-stop, hard-core music. Those street punks have been named "Rudies" by the people of Canterlot City. They roam the streets and cover the city with their personal graffiti, claiming it is their way of expressing themselves to the world.

However, ever since the Metropolitan Government and the financial conglomerate, The Neighsay Group, combined their efforts to co-found the "21st Century Project," the streets of Canterlot City have never been the same again. Police crackdowns on the Rudies have become more severe, and Councilman Neighsay is more anxious then ever to put them behind bars.

The streets of Canterlot City are about to explode...
