Meh, I felt it was a bit weak.
Maxim has 2x the range, same damage, uses less energy (or seems to), has the same fire rate, and also does nothing to shields.
The range is a bit too short too take out many capships, the drain on energy stops you from firing after a while, and it's useless vs fighters.
What I mean by too short is the fact that you can't "sit" you get cranked by missiles, fighters, plasma turrets, and pretty much anything that can either move, or fire the same distance.
Sound and light can be modded out.
Fear the maxim cannon!
