BP updated & added 8 turret mounting points on each corner of the space station. You'll now find 4 extensions on each corner, each capable of holding 2 turrets. This will help provide some built-in defense points that you can upgrade, should drone attacks be added to the game. In total, you can now add 32 defensive turrets to the base.

If weapons are added, I'd recommend a mixture of heat seeking rockets, flak, and/or miniguns.
