I have a problem with my Osiris' battlerazors. Specifically, the razor on the port side.
I've noticed that that it will not fire on occasion, even though its assigned weapon group is chosen. And even when the energy is sufficient and the cool-down period has expired (refire rate of .25). The starboard razor has not had this problem.
Sometime you can be aiming in a zone that your port razor can shoot at. Therefore it will not shoot.
If it can shoot, whats the problem? ive had this on the osirus as well, my BR wouldent fire as ordered when it should have, and sometimes ive had the energy drain but no shot fire at all.
Try using the ' button and see if you still have the problem. ' will fire all of your selected weapons in the direction they are facing, not very useful for combat unless you're using rear firing missile turrets, but it should sort out whether your problem is actual, or if you just aren't aiming your mouse in a direction that the turret can shoot.
