After each +10000 score player gains another bullet.

For getting the starting points of bullets i used this algorithm:

https://stackoverflow.com/questions/3542402/partition-line-into-equal-parts

Which divides line into equal parts based on a weighted average of starting points.

var A = position.y - y/2-3;
var B = position.y + y/2+3;
 
for i in range(num_bullets):
    var k = float(i)/float(num_bullets-1)
    bullet_position = position
    bullet_position.y = A*(1.0-k)+B*k
    add_bullet(bullet_position)

'num_bullets' starts at 1.

'y' is the size of rectangle of the Player ships sprite texture in the respective scene.

+/- 3 is a magic number:)
