Old Republic mod for Forces of Corruption, the one and only good enough for you.
Added 6 light turbolaser turrets to the leviathan model, I also reduced the amount of fighters it spawns, deleted the 4 original light turbolasers and made the 6 light laser cannons untargetable because it had so many hardpoints it took too long to destroy.
They're not that visible but they were intended as small eye candy, not large attention drawers like the turrets of the sith destroyer, which I altered slightly aswell.
Remember I recently uploaded 26 minutes of lategame republic vs sith gameplay, which wasn't uploaded to moddb because of upload limitations. Glory shot of that battle few screens back.
