GoldenRivet is right. Well, manning the gun myself, ok. To bad you can't slave the other guns to your aim...hmm. Anyway I wondered why the AI boats and ships come at you all guns blazing. Including the Flak-Guns. So I thought it would be possible to make the Player Boat thinking its AI. Yeah I know sounds strange but hey I so like that S-boot mod and I hate loosing the Firpower of those four 20mm Guns.
But then again SH3 was supposed to be a Subsim and fighting on the surface isn't an option most of the time, so I can't blame the Defs not forseeing the creative Energy of guys like Mikhayl.
Thanks for the quick response guys I am back on the Helm.
