1. BUILD 3 MASS EXTRACTORS

Schematics added: T1 Mass Extractor
To do this as fast as possible, hold Shift to queue up all 3 Mass Extractors. If they are relatively far apart, queue up a Move command between each one so that your ACU won’t have to walk as far; if you just tell him to build, he will walk right up next to the Mass Extractor before building it.

2. BUILD 3 POWER GENERATORS

Schematics added: T1 Power Generator
Queue up the 3 power generators next to each other, away from the extractors, so that you can place the factory (objective 3) next to them for their adjacency bonus. In general, your first few factories should be accompanied by a row of Power Generators so you don’t run out of Energy – an Air Factory can produce interceptors on repeat almost for free using this method.

3. BUILD AN AIR FACTORY

Schematics added: Air Factory
Place the factory next to the Power Generators. Have your ACU continue to build Mass Extractors and Power Generators, and if you’re making more than you can spend, build another Air Factory. Normally, while factories are being built, you can queue up orders for them. In this mission, you’ll have to wait for the next objective before doing so.

4. BUILD 5 BOMBERS

Schematics added: T1 Engineer, Air Scout, Attack Bomber
After building your initial Air Scout to patrol outside your base, build Engineers and bombers. Have the Engineers develop your economy with Mass Extractors and Power Generators, while one Engineer is set on patrol around any surrounding trees or rocks to collect their resources. If you have extra resources, your Engineers can assist your factory with its production, as can your ACU, which builds as fast as 2 Engineers.

5. DEFEAT THE UEF PATROLS

Set up an attack queue by holding Shift and clicking the enemy units. Your bombers should make short work of the enemy land units; if there are any anti-air vehicles, target them first to avoid losing bombers. If your aircraft are in the air too long, they will run out of fuel (the meter right below their health bar). Allow them to land and they will refuel themselves slowly. In later missions, you can use Air Staging Facilities or some naval units to repair and refuel more quickly.

6. CAPTURE THE UEF RADAR

Move one of your Engineers to the radar facility to capture it. Once it’s yours, the rest of the small base joins your forces as well.

7. DESTROY THE UEF MASS REFINERIES

Map expands to the north
Schematics added: Interceptor
Add interceptors to your build queue. Find a good mix of bombers and fighters, then press the factory’s Repeat button to continue it indefinitely. Have your other Air Factories assist the first to help with its queue. If you give the other factories new build orders (say, if you need more Engineers, or some Air Scouts), they will return to assisting after they’re finished with those. Set your interceptors on a patrol route around your base – you’ll want 5-10 of them before you send them north to battle the UEF interceptors. With those dead, move in your bombers and destroy the Mass Extractors.

8. DEFEAT THE UEF PATROLS

Map expands to the east
Schematics added: Land Factory, T1 Point Defense, Anti-Air Turret

Build several Land Factories, along with Power Generators next to them so that you don’t run out of energy. Have them build a couple Land Scouts for radar coverage, then a continuous mix (put the queue on repeat) of land units. Set the primary factory’s default orders to patrol along the east of your base. You can now build up an overwhelming force, protecting your base with turrets, assisting factories with your ACU and extra Engineers, and move in when you feel you’re ready to crush all opposition. The enemy will attack only from the air until you move in to defeat the patrols.

9. DEFEAT UEF OUTER DEFENSES

You’ll need mostly ground units to defeat the two defensive posts in the north and south. The middle defensive post can be destroyed with one fell swoop if you have enough bombers: simply target the easternmost Anti-Air turret and the bombers will destroy all its anti-air defenses on the first pass and the rest on the second pass. Don’t let your bombers stray north or south; you’ll need them for the next objective.

10. DEFEAT SYMBIONT GUARDS

Map expands to the east
At this point, you should be close to the unit limit. Try to keep your economy as close to +0 mass as possible – if you have extra, build more factories, and always build Mass Extractors anywhere you can. If you have too little, you can pause some Engineers by pressing Z. The new UEF base has a lot of Interceptors guarding it – bring in your own air force to destroy them while simultaneously bringing in your own ground forces from the south. You should pass right through the enemy base, which surrounds the Symbionts you need to free. Once the interceptors are destroyed, you can bring in your bombers to support the ground forces, especially to take out problematic Point Defenses.

11. DESTROY THE UEF BASE

Move northward from the Symbionts with your land forces. If you’ve eliminated the Anti-Air turrets, you can bring in your bombers to make short work of any remaining buildings. Keep your fighters patrolling outside your base and have them swoop in if any enemy fighters show up.

12. DEFEAT THE AEON COMMANDER

Map expands to the south
Schematics added: T1 Air Transport

Build several transports and have them set up a ferry from your base to the front lines. (See part 1 of this guide for more info on ferrying.) You should build up an enormous land force consisting mostly of Mantis assault bots with support from the other ground units (plus a cloaked scout for radar coverage). Your huge force should just head straight south to the center of the enemy base and attract the enemy Commander. When she comes out, send all your air units to attack her, with the fighters coming in to confuse enemy anti-air. The combination should finish her quickly.
