So, I was stuck on the last mission, with seemingly no way to hold off the enemy. I tried everything I could to survive, but nothing was working. I tried to look up a guide, but nothing. There are seemingly no videos at all about this game on the internet. So, if you're stuck, try my method of winning.

1. Form a defensive line at the front of your starting cities with the launcher in the back, and the troopers at the HQ.
2. Build a stormwhatever for anti-air.
3. Focus on killing the enemy AA with the missile launcher; although you won't get them all.
4. Build a dropship and grab a trooper.
5. Build a raptor.
6. Take the western island with the raptor and dropship.
7. Your defenses should be falling by now.
8. Pump out raptors from your new western base, and move to take the eastern island. On both islands, block the construction of new raptors with your dropship, and grab the cities first.
9. Keep three raptors off the coast of your HQ.
10. When the ai tries to take the HQ, move in with the raptors. Two of them will probably die on the enemies turn.
11. When the western island is taken, take the dropship, and the trooper to the northeast factory and start taking it. This will make the AI send a bunch of units away from the main base to your location.
12. Simultaneously send at least two raptors up the west side of the map, and go towards the enemy HQ.
13. Pick up the trooper to the east with the dropship and skirt the northern edge of the map to make your way to the HQ.
14. Put your raptors in front of the HQ, and drop your trooper into the HQ and take it over.
15. The raptors will get shredded, but should keep the heat off of your trooper for a turn.
16. Put your dropship in front of the HQ to shield your trooper again.
17. You win.
