So if I put a railgun or ion blaster in one weapon slot, then that covers all the turret/blaster slots on my ship?
For example, my Merlin has four weapon slots. I have a mining tool in one, a missle launcher in another, and a blaster in the third. I can't put a railgun or turret in the fourth as it says my turrets are there already.
So what can I put there? More missles? Rockets? Torpedos? A squirt gun?
