So i've played with weapons_equip.ini a bit and made this. It supposed to be a ballistic turret, just take a look at this.
As you can see, even if shield damage declared in the infocard, these turrets deals not any damage to the shields at all, so i had to equip this 'kirk with bunch'a'EMPs.
I think that we shouldn't change the game that much. Each game has (or should have) its own specific atmosphere. This is Freelancer, not World of Warships. This could be a good anti-cruiser/gb weapon if it had a detonation range, but there are more FL-like ways to make the same.
Good work, though. And interesting sound effects. Quite a nice ship too.
