In Rock'N Roller, the player takes control of a buggy that must find, in each of the 30 stages, the six parts of a prototype car, which are hidden throughout the stage.

In each stage there are three types of enemies: fast cars, armed off-roaders and a giant helicopter equipped with missiles. In addition, there are various traps (such as dangerous bridges, oil puddles, mines, etc.) that must be avoided and a fuel limit that must be taken into account.

ROCKY DRIVER had always dreamed of one day competing in a professional race, but unfortunately no one had ever trusted him enough to give him a chance. That's why he had to settle for a job as a test driver for a company that makes new racing car models.

However, now he had the great opportunity of his life. His boss, who was very happy with him, had decided to give him the chance to race in the Illinois Grand Prix. But to do so he would first have to test the new car models that have just been manufactured. There is only one problem: the powerful FUNESTA organization, led by Professor "CHUN-GO", is going to do everything in its power to prevent these new models from passing the test and it doesn't care at all how to achieve this.
