In the game, JetPac has to first assemble his rocket, and then fill it with fuel before taking off to the next planet. Along the way JetPac has to defend himself from the planet's aliens, and for bonus points collect valuable resources which occasionally fall from the sky.

After the first level, the rocket stays assembled and just requires refuelling. However, every five levels, the rocket is changed and the replacement has to be built before it can be fuelled for take off. Each new model has a new design with a higher number written on it, although the gameplay is unchanged.

The single game screen is a horizontal wrap around and consists of three platforms on which Jetman can stand.

The enemies change each level and each alien has a different pattern of movement which means they can be dealt with in a different manner.
