Although it is the last mission, it's pretty easy to win. You will have a large army but you won't be able to build your own units. Every once in a while you will receive reinforcements. You can only call for ODST infantry. Use them to replace empty positions.
You will have a major advantage - you'll have unlimited resources. You will be able to use special abilities all the time. You will only be limited by the time it takes to charge them. Constantly place mines near all the entrances but closer to the professor's position. Treat it as your emergency line of defense. If needed, call ODST, Archer missiles or Pelicans to fire at your enemy (they will move above the selected area for some time. Build turrets wherever it is possible. If there are two areas available, upgrade one turret to the anti-personnel version and the other one to the anti-tank one. Although flying units will appear halfway through the mission, you will get Wolverines soon enough.
Divide your army into two similar groups - the north and the south one. Each will defend two entrances. You will have to move them according to the situation. You will have an opportunity to eliminate the Warlords soon enough, so send all your troops towards one of them, and strike the other one right away. You need to eliminate the leader, not its troops. Complete this optional task and get back to your defensive position.
About halfway through the mission, you will be attacked by a single Scarab. You will also obtain your superior unit - Kondor. It deals major damage and can fight with several enemies at once. Use its special ability on the Scarab but finish him off with the Archer missile. You can create a third group of troops which consist of flying units only: the Condor Gunship, Vultures, Locust and Nightingale (divide the nightingales among all the groups). From now on, the Banished will strike with Locust, Blisterbacks and Wraiths. They will often send Banshees. If you keep your troops in large groups you will easily deal with enemy attacks. Your last challenge is to survive 2 minutes, during which you will be attacked by 3 Scarabs. Defeat them one by one, using all your forces from the north part. Support your efforts Archer missiles, call for 4 Pelicans to fire at their position. Once you destroy them, the enemy will continue to send troops but don't worry - you have just completed the last mission.
