Quick thought along the lines you were thinking with the facing issue. Can you set to false or off, so that it need not face the opponent to fire, and if that is so, will it then fire on multiple targets?
In the platform beam weapons for the beam defense, i got the BD to fire on multiple targets, although cosmetically it was sorta weird i entered values for front, back, right and left.
There are no firing points of course on the other sides, and so the weapons fire came out of the hull of the BD, but it did work.
Dont know if that helps, but hope you find it,
take care,

P.S. after posting i thought if you brought it up you probably tested it, sorry. Hope you get it.
