First off, amazing work on this.

I have a suggestion, i thought that the laser artillery turret would scale with the vanilla infinite artillery research and was disappointed when it did'nt, I think that it should but with an increased cost to boot, its not very power intensive for such a powerful laser turret. I don't know how to do that my self so I can't just edit that my self in my own game :)

Great looking turrets!

Thanks!
Unfortunately, due to game limitations, the Laser Artillery Turret is a generic game turret (not an artillery) and cannot be increased in radius :(

I hope that I am not breaking any rules that I am writing here.
In the mod "Endgame Combat" have a study to increase the firing range of turrets. It also applies to standard turrets(not artillery). Maybe take a look and take it for yourself.
