Yes, Some Details: I have noticed that any beam weapons only have a range of 500, regardless of the range stated in the weapons info box. I found this when I was bulding a long range beam weapon and i could not hit a distant ship even though a long range cannon with less range could.
Are these the details you were looking for? If you need more info just ask me.
I apologize for the delay in my responce. I haven't been on the community for a while.
