1. DEFEAT THE AEON COMMANDER

There’s no time limit for the first task, but you’ll be continually assaulted, so build up defenses on your western side. The Aeon Commander is to the southwest. Build up a large navy and Wagner force (they have torpedoes so they won’t be defenseless while crossing the bay), with air transports to bring in Vipers and Rhinos for the heavy base assaults. Your walking destroyers are key here, as they can do anything you need. Scout out the southwest base until you find a good place to air drop your forces. Before moving in, build up a decent force and send in your Destroyers so they emerge from the water, causing the enemy defenses to target them instead of your land units. When the Aeon Commander shows up, attack with everything, including bombers and gunships; she’ll teleport away, but you’ll need forces there anyway for objective #2.

2. RECAPTURE THE NETWORK NODE

The node is in the middle of the base you’re attacking. Capture it with an Engineer once you’ve leveled the base. Have your naval forces (not just your Destroyers) destroy the naval side of the Aeon base there.

3. SAVE THE NETWORK NODE AND CIVILIAN BUILDINGS

Map expands to the west
The civilian village already has shields, but you’ll want to airlift your land units there for defenses while you erect a defensive position. Build a Land Factory there so you can have mobile defenses, and build some anti-air as well.

4. DEFEND THE NODE AGAINST AEON ATTACKS

The node will come under all kinds of attack – your Land Factory making T2 flak and heavy tanks comes in handy as all-purpose defense. Move your naval forces to the north of the village to find the naval attack before it happens and destroy it.

5. CAPTURE THE NORTHEAST NODE

Map expands to the north
Your original base is now vulnerable to northern attacks, so build some defense there. You can either move in with a large force to overwhelm their mobile shields, or send a mobile stealth generator and an engineer with your air transport (after scouting out their flight paths) to capture it.

6. CAPTURE THE NORTHWEST NODE

This is relatively easy: simply move your naval forces to the coast and they will shell the base into oblivion. Before capturing the node, move your entire army just outside the main Aeon base in a huge formation. You have a time limit for the next objective, so capture only when ready.

7. DEFEAT THE AEON COMMANDER

30 seconds after completing objectives 5 and 6, an EMP bomb goes off in the middle of the Aeon base. This gives you time to raid the base with everything, find the Commmander, and kill her with gunships and bombers before their air defenses reactivate.
