After you've beaten all of the airplanes (and the ship comes) go to the upper left hand corner. Then begin firing at the ship while moving right.
Note: The ship will take about 8 hits.
Easy Points
To get easy points, first build your sheilds up to about 6 or 7. Then fight 4 small (star) ships and 1 big (star) ship. Small ships are worth 400 points and the big ones are 500.
Note: This counts only if you haven't beat any countries.
