ResExsention So it's a 3x3 or 4x4 part that decreases crew requirements (that have more then 1 crew) for weapons by 1. It can also "automate" weapons in an alternate mode, though with some negative side effects.
Personally, I would like it to be a very weak 3x3 or 2x3 part that would have to also be exposed to function. It would provide a major projectile Speed buff (which can be stacked), and would increase the range of the ship's weaponry. However, it has a major energy cost similar to a huge thruster, and is very expensive (I'd say about 40k).
Pros:
Provides a Projectile Speed Buff (Wouldn't apply to Railguns, Tractor Beams, Missile Launchers, or Ion Beams)
Increases Ship Weaponry Range (Buff for all weaponry)
Non-Explosive (It's only being fed energy, so it'd probably have the same qualities as energy storage)
Cons:
High-Cost (To buy the part, a High energy cost, and to Repair the part )
Low Hp and Low Resistances to basically anything.
Unable To be placed well internally in ships (Was thinking a "no build" zone the same length as the boost thruster along the 2 side (2x3 version)or the 3 side (3x3 version).)
Small Energy Storage (Like if it needed constant power like a shield generator it would only have 4 energy storage instead of 6 or 8)
