Everything that doesn't have a power penalty applied, or it's not working properly:
(Standalone missile works fine, power penalty is applied and it's the correct value)
* Missile + Cannon
* Missile + Beam
* Missile + Missile
* **Missile + Pulse somehow uses the power consumption numbers of Missile + Missile (also with no power penalty applied)** so it's roughly 3 times less of what it should be
* Beam
* Beam + cannon
* Beam + Missile
* Beam + Beam
* Beam + Pulse
* Damage Pulse
* Damage Pulse + Cannon
* Damage Pulse + Missile
* Damage Pulse + Beam
* Damage Pulse + Pulse
Power penalty is there to keep gun arrays within sane limits
