my NBM tactics on 5/10 ... build east then south to take the island. also take the upgrade. when the creeps come you should have enough energy to defend these 2 fronts with one blaster each side, then 2. also, just after getting on the island you should build a mortar. then you should be able to survive, build some reactors and off you go
sure TheEveningDragon, I first go for the mountain on SW, until I get the bonus, and also take the territory W. The trick is to develop fast enough, but not too much since you need to build a first blaster, and a mortar for the SW hole. Then a second and third blaster with some reactors. Finally when I have enough energy attack E, use a mortar (either the one you have or a second one) for the hole SE, and conquer the E mountain.
