Extra Lives
When in the narrow corridor in stages 1, 3, 5, and 7 pick up the 'A' and change into the Armorator. Carefully ease into one of the bottomless pits. Line his shoulders up with the top of the pit. Slowly press Up and fire at the oncoming flying creatures. You will reach a level where you are even with the creatures and you can maintain this position as long as you do not move or adjust your control pad. Keep firing; you will gain an extra life at 30000, 70000, and 120000 points.
