Internal levels
The term internal refers to one of the 54 default levels that come with the game, and finishing and improving them can be considered to be the main objective of the game. Some of the levels have been played ever since the release of Action Supercross in 1997, therefore the world record times and rides are getting closer to perfection or insanition.
