If you fire with lasers you hear nothing, you see a light and the enemy pops.
if you fire with railgun, you hear a noise and the enemy ship pops.
if you fire with autocannons, you hear an even louder noise then the enemy pops.
if you fire with rockets, you hear two noises, that from the rockets and the enemy pilot crying noooooooooo
then he pops.
thats why i like rockets :)
