Trapped in an underground cave system, you have to escape by travelling through all the caves before your energy runs out. You will come across different aliens which you have to dodge and shoot. If you kill one of the aliens , it will reapper at a set position.

Your man can move left, right, climb ropes, jump and fire. To jump you press the „B” button. The longer you keep the button depressed the higher the man will jump. The man automatically fires in the direction the face is pointing.
