Star Fighter (スターファイター)
As in the original Bosconian arcade game, you must take control of the Star Fighter that the Federal Council had originally developed back in 1981 for the purpose of destroying the Enemy Bases for a second time. It is now equipped with four different varieties of firing patterns, the colours and directions of which have been explained to you on the main page. It still has the ability to move in eight different directions, but is now always facing the top of the screen and moving upward, while the background scrolls downwards behind it and brings the enemies into view. It must still avoid contact with every enemy (except for the Jiara and Furemu Launchers in the background of World 3-3) and every shot fired at it, or it will die and be sent back to that area's quarter-way, half-way, or 3-quarter-way checkpoint. It will also receive an extra life at every 80,000 points by default, but this bonus setting can be modified. To the left is how the Star Fighter appears at its normal size in the first and second areas of each world, and to the right is how it will appear at its larger size in the third area of each world.
