I don't really like it...the range is high the fight pilot won't have enough time to get in firing range or dodge if it is a turret...
I like weapons like the minigun : rate of fire 30.00 low damage due to the high rate of fire....and it would have a nice firing sound...not the pew pew pew i am used to.
Also i would like to see a gun like modern battleship 16inch guns...
Low rate of fire. It would fire a missile (it would represent the shell) at a speed of 1500 m/s and hight damage output and high engergy consumption (it would be used for capital ships)...and since it is a missile it would leave smoke trails...=P (probably doesn't fi with the rest of the universe; hey if you see EVE online a faction has plasma guns and such like all freelancer ships and another nation has bullets and shells)
