Connect drones with each other and control the distance between them. Eliminate all hostile units before they destroy your cluster by choosing the right position.
Face your enemy in the outer space and hold his attack. There are many drones moving towards you, but you can add units the echelon and build a cluster. If you do that, fighting your enemy will become much easier. Relocate drones to better positions and shoot incoming waves of your enemy having a huge advantage. Are you ready to win this battle?
