Gyruss/Walkthrough

Neptune
Enemies will come from the center, diagonally opposite of their convergence point. They circle towards it, advance, and circle away before falling back to the holding pattern. For these waves, the convergence points are at the bottom, bottom-right, bottom-left, and top.

As mentioned in Getting Started, if you kill the first four waves, an additional wave will appear. It's approach pattern is randomly determined.

The fighter colours in each wave are generally based on the wave, but the actual colours of some craft may vary:
 * 1) Light blue
 * 2) Gray, with a light blue leader
 * 3) Dark Gray, mixed with dark blue
 * 4) Red, with a dark blue leader.
 * 5) Light blue

In the chance stage, the first enemy wave will come from two directions at the top, and make three half-circles around the center before departing. The second wave will appear in a single line, appearing in the bottom-left corner and heading to the right before looping back. The third is a vertical mirror of the first, and the fourth has the fighters move to the left instead of the right (but still starts in the bottom-left.)

Uranus
In the change stage:
 * 1) Enemies make a partial convergence at the bottom-left.
 * 2) Enemies arrive on the bottom-right, and split in two on the right just as they make three half-loops around the center, and cross before exiting.
 * 3) Enemies make a partial convergence at the bottom-right, before crossing...
 * 4) Enemies arrive on the top-left, and split in two on the left just as they make three half-loops around the center, and cross before exiting.

Saturn
Enemies deploy in single file formation, circling as they reach the center.
 * 1) From the top-left, heading downward.
 * 2) From the bottom-left, upward.


 * 1) From the bottom-right, upward.

During chance:
 * 1) Arrive from the center, making a partial convergence to the bottom-right before doubling back and crossing at the top-left corner.  You can still hit them until they reach the top or left after crossing.
 * 2) Arrives from the bottom, crossing twice there, before a double cross at the top.
 * 3) Mirror of first wave; partial at top-left, and cross at bottom-right.
 * 4) Mirror of second wave, enemies arrive at the top and work down.

Jupiter
Enemies deploy in single file formation from the center before breaking for holding or attack.
 * 1) Enemies start from the top, before looping to the right.  They circle a bit on the right, but are known to break formation before then.
 * 2) Single file wave, starting from the bottom and turning to the right.
 * 3) Single file, approaching to the left.
 * 4) Single file, starting at the bottom and turning to the left.

During chance:
 * 1) Enemies cross themselves at the bottom, loop in the bottom area, and cross before leaving.
 * 2) Enemies appear at the top, reversing before crossing, make a tight circle at the bottom left, before crossing.
 * 3) Vertical mirror of first wave.
 * 4) Vertical mirror of second wave.

Mars
Enemies deploy in single file formation.
 * 1) Enemies approach from the center staring at the top, circling around to the right before a tight loop at the bottom.
 * 2) Enemies approach from the bottom-right, and circle around via the top.
 * 1) Enemies approach from the bottom-right, and circle around via the top.
 * 1) Enemies approach from the bottom-right, and circle around via the top.

During chance:
 * 1) Enemies arrive and cross at the right, make a quarter-loop before turning around and crossing before exiting.
 * 2) Enemies arrive at the top and cross, make a quarter-loop before turning around and crossing, and complete the circle by crossing and exiting at the bottom.
 * 3) Horizontal mirror of first wave.
 * 4) Vertical mirror of second wave,

Earth
Enemies on this wave have an aggressive approach pattern. You may want to get out of the way to be on the safe side.
 * 1) Enemies arrive at the bottom-left and bottom right, make tight circled before going into holding.
 * 2) Enemies arrive at the top-left and top-right, with tight circles at those places.
 * 1) Enemies arrive at the top-left and top-right, with tight circles at those places.
 * 1) Enemies arrive at the top-left and top-right, with tight circles at those places.

During chance:
 * 1) Enemies arrive at the bottom, crossing. They make a complete circle around the center before crossing and exiting at the top.
 * 2) Enemies arrive from the left, crossing.  They do a quick circle at the top-left and bottom-left, before making a quarter-loop and doubling back.  They make a final cross at the left before exiting.
 * 3) Vertical mirror of first wave.
 * 4) Horizontal mirror of second wave.

Neptune redux
At this point, the enemies will repeat their initial attack patterns. However, they will be at increased speed, and you will still have to deal with the asteroids and laser beams as well.
