So, i when i first noticed the small laser blaster, i thought that there would be a larger version, surprise, there isn't, so i though that maybe there could be larger laser weapons, or maybe, replace them with Plasma weapons, because honestly, lasers (while cool) are not very realistic, granted cosmoteer has no real plot, but i think replacing the small laser with plasma would allow the large plasma weapons make a bit more sense, give them a bit of continuity, nevertheless, here are my ideas (this has descriptions, truly we live in the future)
Small Plasma Turret
180 Degree Radius
Crew required: 1
Power needed: 1
Power storage: 2
2x1
This is literally the small laser
Plasma Cannon
95 Degree Radius
Crew required: 1
Power needed: 2
Power storage: 4
2x3
This is a larger plasma turret, it is constructed in such a way that the turret is mostly internal, allowing the weapon to be better protected in combat
Heavy Plasma Cannon
90 Degree Radius
Crew required: 2
Power needed: 3
Power storage: 6
3x4
A heavier version of the Plasma cannon, it retains the same internal weapon design, it has heavier armor than the lighter cannon, this is good for combat
The cannons are broadside weapons, this is why they should not replace the projectile cannons, as they are useful for heavy weapons with a high turn radius
