..... what. Please allow me to enlighten you. Cannons = firing speed increase, for everything. Missiles = split, with an exception for pulsar because of the way they are generated. Beams = increased range, for everything, pulsars get expanded radius. Pulsar = more damage but slower. I have no idea where you got this concept that the combinations are hard to understand. You, meanwhile, are hard to understand, what with not putting text on your post.
