In moon patrol you play a moon buggy trying to finish as many of the levels as you can with your infinite lives. When you press the fire button you shoot a laser forward and one up. This is because some of your enemies are on the ground and some can fly. The enemies on the ground are little red blobs that you have to shoot and the flying enemies are flying bras. When the enemies on the floor die they leave holes in the floor that you have to jump over which can be quite tricky.
