From here, I’ll assume you know how the game works and I’ll stop reminding you to build Mass Extractors, queue up orders, put factories on repeat, etc.

1. CLEANSE 80% OF NEW CATALON

Before moving north to destroy the Cybrans, build up a decent-sized force, with a Naval Factory and multiple Air and Land Factories. Concentrate on Cybrans and destroy civilian facilities at your leisure.

2. REPEL CYBRAN COUNTERATTACK

At 15% of New Catalon destroyed, the Cybrans will launch an assault. Make sure you have plenty of air protection and you should be fine.

3. DESTROY CYBRAN BASE

Map expands to the north and east
Plenty of naval units are in order for this one. Destroy the naval outpost to the east before moving to the Cybran base in the northeast. You’ll need to do lots of island hopping, so establish naval and air superiority before moving in Auroras, which are amphibious and can swarm through enemy weak points. If you want to use T2 land forces later, you’ll need Air Transports to ferry. Alternatively, upgrade your Commander for combat (Personal Shield, Heat Sinks, and Crysalis Beam) and use your naval units as cover to let him cross the river. Once he’s on land, he can destroy the base and then the secret base with only anti-air and torpedo bomber support to make sure he doesn’t get shot down by bombers or destroyers.

4. DESTROY CYBRAN SECRET BASE

Map expands to the east
The Cybran naval units to the east are lacking in air defense, so a combined assault with naval forces and bombers works well. Clear out the anti-air defenses in the south end of the base, then load up transports with land units. Drop them in the south and move north while using your naval units to keep the edges of the sea free.

5. PROTECT 80% OF HUMAN SETTLEMENT

Drop your troops (or just send the Auroras over first to make a beachhead) on the southern tip of the northeast island. Move north through the civilian structures and destroy Cybran forces there.

6. SURVIVE THE CYBRAN ASSAULT

Schematics added: T2 Air Factory, T2 defenses

As soon as you destroy the Cybran base, the Cybrans counterattack from the north. Use your new T2 engineers to protect the northern edge of your base with T2 air defenses and you should be fine. If they manage to air drop units in your base, use your Auroras and bombers to take them out.

7. DEFEAT CYBRAN COMMANDER

The Commander is recalcitrant, and he’s in the northwest. Move your naval forces out to attack the island, and when he comes out to fight you, pound him with bombers and Auroras. Most likely he’ll try to escape in the water, which is the easiest way to kill him: use your air force to take out torpedo launchers, your land force to drive the Commander underwater, and your sub fleet to kill him very quickly.

8. DESTROY WESTERN CYBRAN BASE

This island is too big for the Commander’s explosion to destroy it. Use your remaining troops to mop up the base, or if the Commander was killed in the water, turn your attention to the eastern base first.

9. DESTROY OR CAPTURE 2 CYBRAN ARTILLERY POSITIONS (optional)

Air drop your troops on the western shore of this island and move east until you get to the river separating the main Cybran base from the northern island. Concentrate your production on T2 aircraft, frigates, and Auroras. Send in a few Engineers to capture the artillery on this northern island; it will then fire on the eastern base to soften it up for you. If you have a fighting Commander, he can capture these on his own, and then construct some defenses for them while holding off enemy frigates himself.

10. DESTROY EASTERN CYBRAN BASE

Move in all your forces for a combined assault. Fairly straightforward. Objective 9 helps greatly here.
