Now, I don't have the slightest clue if this is even remotely feasible.
Assuming its possible, I think it would be nice to have additional weapon assignment slots for ships.
I want to build a gunship where I can have weapons of each "damage type" that is player controlled so I can target enemy ships and have the ability to use suitable damage types to take down enemy ships; but I absolutely love having an automated defense system in the way of turrets to protect my blind spots when in ship battles.
Even if there is a way to rework the turret script to not take up a weapon assignment slot and just have it passively active, I'd be totally okay with that too.
