read on for patches to give you more options with turrets, and fix AI not being able to shoot
Currently we have no way to buy and sell guns on a turret. Until that is fixed we needed a workaround, so I just added a bunch of new turrets: one for each type of gun. The prices are equal to turret + two guns + tractor beam.
I was a little late to get them into beta 009 (sorry) but I might create a little patch that can be applied to 009 installations if people want to have different guns on their turrets.
