This week, we continued our crusade to make invasions a little more interesting and dynamic. This time adding a hovering security drone for placing defenses, and a keypad for unlocking locked doors.
The security drone makes getting attacked much more interesting, because you can no longer just drop down a giant turret in the heat of battle. You are forced to choose between standing your ground and fighting the aliens off yourself, or running to the security room to buff your defenses.
