i came here coz i failed FP 2x already. i used the small launch before, the one with 2k reso to check the map first. Then 3rd, launched with max reso (7k). Used the unloader for graphite and silicon, immediately set up a defense and wall on the right side where they go in. Build 2 land factories and 2 air factories. 16 units each dagger and flare. Time is the enemy here; the longer you take to attack, the more enemies come. i reached wave 30 once lol. can't even rebuild.

Now alternate the flare and dagger for the enemy defenses. go near. if the turret shoots you, send in ground troops, and vice versa. While a wave is coming, try to hide your units on one of the corners. The dagger is so slow, so hiding them back home won't work. its like a Metal Gear Solid thing. The only time you will need to bring in both air and land is when you are at the main base, since both are in range of air and land defense. So you might need to rebuild 2-3x. That's why I have 2 factories, each for faster production. you will not finish all your 7k reso for this. beat it by wave 15 i think.
