Motor Rock is an unofficial 3D remake of Rock 'n Roll Racing. Like the original, it is a racing game where drivers from various planets compete in an intergalactic championship using both their skills behind the wheel and the deadly weapons and booby-traps their vehicles are equipped with. The game features several modes, including single races and tournament. In the tournament mode, the player must win enough races to continue to the next planet, using the money earned by his victories to upgrade his current car or buy a more powerful one. A multiplayer mode is also present.

The game offers two views: the classic isometric view of the original game and a rear view more similar to 3D racing games like the Rock 'n Roll Racing's sequel Red Asphalt. As in Rock 'n Roll Racing, the soundtrack is comprised of arrangements of famous rock songs.
