- As the ships fly in formation on the screen, don't shoot any of them
- Locate the 2 blue & yellow ships in the first vertical row on the left
- When all the ships are on the screen you may begin shooting, but don't shoot the 2 mentioned above
- Once you have destroyed all but these 2 ships let them fly around, shooting at you for about 15 minutes.
- At this point they'll stop shooting
- Blow them away and from now on no ships will shoot at you for the entire game!
