Strategy:
You have an incomplete camp at the point 1. Complete it and be prepared on air attacks from North. Use Homing Bazookoids and Bazooka Batteries against them. Build up Towns in the entraces to your camp and power resources. Then make 10 Fighters and destroy Survivor's camp at the area 2. Then clear up the rest of the map. That's all.

Hints:
1. Use Bazookoids as a sole group. The concentrated firing can destroy the enemy plane by the first volley.
2. Decoy enemy planes by Mekaniks. Locate them on the North of your base.
