On certain levels you will have to fight super-sized aerial craft called Capital Ships. In a fixed place on each of those levels, a large craft will appear and zoom around the screen firing various projectiles at you in a fixed pattern. Your weapons will literally bounce off the surface of the craft; although they still do damage this slows your rate of fire.
Eventually, after being hit enough times the ship will change color. First, the ship will turn yellow and then after being hit some more it will turn white. After you shoot it a few more times it will freeze in place and become dotted with small explosions. Then it will self-destruct, hurling a ring of missiles in all directions.
If you do not destroy a Capital Ship, it will depart at another fixed place later in the level.
Maseru
2000 points. Maseru appears in the 2nd and the 11th Areas. After warping into place, it hesitates and then scatters Leads around the screen. It can withstand 25 shots before it is destroyed.
Hume
2000 points. Hume appears in the 5th and the 9th Areas. When it appears, it fires a series of rotating Leads throughout the screen at the Zanac ship. It can withstand 40 shots before it is destroyed.
Girevu
4000 points. Girevu appears in the 6th Area. It fires Leads from 16 different locations, all of which will pursue the Zanac ship. It can withstand 40 shots before it is destroyed.
Soreido
4000 points. Soreido appears in the 7th Area. It deploys very strong bolts known as Super Hard Bolts. They drift slowly across the screen. It takes a good degree of patience to fight this enemy, in order to pull it away from the bottom of the screen so that you can get a good shot at it before it gets too close again. It can withstand 60 shots before it is destroyed.
Somasu
8000 points. Somasu appears in the 11th and 12th Areas. This formidable enemy shoots three kinds of rotation bullets; Leads, Mios, and Beruos. While doing so, it slowly moves in on the Zanac ship's position. It can withstand 100 shots before it is destroyed.
