I have 3 missile turrets on my Behemoth. But they didn't fire, when somebody attacking me. Why this turrets don't work? Please, help me with an advice.

You need another player to man the turrets manually, while you fly the ship.

use /gunner invite "Player name" to invite another player on to your ship to man the turrets.

Looks like he needs the advantage everyone else seems to have and complain about, so just make em automatic already?
lol.

LOL Yep Kierky
