Motocross Madness is a motocross racing game that was released on the PC and was developed by Rainbow Studios and published by Microsoft Games. The game was released on August 14, 1998. There are several modes of play, including Baja, Stunts, Enduro, Supercross, and National levels as well. The "Career" earns you money, which can be used to unlock more motorbikes and biker skins. The game has both large outdoor and indoor areas to explore and a physics engine that was new to games at the time. A simple, easy-to use track editor was included with the game, using pre-determined templates to build customizable tracks, which can be sent between players. LAN multiplayer was included for online play between up to 8 players at a time and up to 4 players can play at a time through the internet.
