A good read, and the screenshots were nice.
Quick question: Do the PD drones hover within shield range if they aren't engaging anything?
Thanks!
They stay a bit outside shield range - 50 pixels or so. Need to, to be effective at taking out incoming missiles.
You can press 'F' once to let them roam more, and press 'F' again to make them land on the mothership (and stay until you order them to launch by pressing 'F' again). So if you're concerned about them getting taken out, that's what you'd do.
