Special Rules: Your scoring attempt ends when you lose your 3rd, 4th or 5th life, depending on if you succeed in getting Extra Lives. Please note, that when you allow your ship to be captured, that counts as 1 LIFE! As you're sacrificing One of your own lives for the added fire power. If your ship gets captured on its 5th life, your score ends there, as you're technically using a 6th life to continue on and gain the added fire power.
Usage of the trick to cause enemies to stop firing is banned.
