Drone carrier AOE exploit - possible bug
The drone carrier shield logic looks like this - the shield shuts off once you remove it's link drones, we all know it. The trick is the drones are launched one by one, and therefore you can clean up the drones using an area weapon (the Neutron Cannon is the best choice) way before the last drone launches (with enough luck you'll actually have to kill only a couple of them to trigger the effect). As a result, the carrier shield will be down again (as you actually destroyed all the active drones, no matter there were only 2 or so at the moment) while it keeps launching the remaining drones, and the silent timer on the shield reactivation resets, giving you plenty of time to destroy the thing. Don't know if it's supposed to be like this.
