Supreme Commander 2/The End of an Alliance

Titans of Industry
After briefing, you will be provided with a pre-built base with two air factories. There will also be two fatboys attacking from the east, but they are slightly delayed since they try attacking terrain en-route. Repel these two fatboys by building bombers or other air-to-surface units, and make sure there is a fighter escort.

Once the fatboys are destroyed, you will be given an objective to capture the two other production facilities, while your own factory will start producing automated fatboys. Increase your airforce for anti-air (to cover your own fatboy) and bombers (to detroy incoming fatboys). Your first expansion should be to the east towards factory Bravo, which is the closest production facility. Clear all units there, and send your ACU to the southern factory and build a secondary base.

You will now need to capture factory Charlie. Follow the same tactic - build up air units, and have them clear out the northern factory. You will also need to make sure your airforce is strong enough to remove the large cluster of patrolling aircraft to the right of the northern factory.

Once you have control of all three factories, prepare for a counter-attack. This will be a deployment of enemy ground troops and the ACU, just outside of your base, and it is triggered once the fatboys start causing significant damage to the main enemy base. The attack will head to your initial location, and is still vulnerable to an aerial attack.

Factions or Family Plan
In this mission, your base will be under constant attack. Until your forces become strong enough, you will need to protect your own base.

Your first tactic is to improve the defence at the front. There are already two pre-built defensive locations, and they can be improved. Put research towards shield generators, and build one at each of the defensice points. Next, harden those defences by placing point defence turrets - about three on each side should prevent them from falling. To prevent units slipping past the side, build two point-defence turrets on each side beyond the shield generators.

Once defences are built, start constructing your main attack force, with both bombers and ground units. If you want to construct a fatboy, you should keep it under a shield generator with anti-aircraft fire until you are about to assault the enemy - the enemy will attack the fatboy with 11 gunships.

After 10 minutes, the mission area will expand, and two missile silos will be marked for attack. If attacking with bombers, try a hit-and-run on either the anti-air turrets or the unit production factories before destroying the silo. Destroying anti-air makes it easier to launch additional attacks, and destroying the production facilities will stop attacks that try flanking your base.

Once the silos are down, press the attack towards the enemy ACU. You can approach from the front with experimental units, or circle around and attack the base from the side.

End of an Alliance
On approach to Rodger's base, you get shot down and do an emergency landing. You won't be able to build until you reach the ally's base. Between your landing point and the base, there are several groups of enemies that are patrolling. You can easily overpower them, but you shouldn't miss the opportunity to capture enemy units, and to reclaim resources of the destroyed enemies.

Once you arrive, your ally gets destroyed. You will need to take over base operations and construct units.

As with the previous mission, build up a defensive line with shield generators, point defense and anti-air. The two resource points at the top of the steps make a good border, needing only one shield and one anti-ground turret. The middle can support two point defences.

Now, clear out the enemies. You will first need to remove the two production factories just outside the base, and it should pose no problem to a large ground force. If you are bombing them, aim for anti-air first, then take out the factories. If you built a fatboy, the enemy will send 11 gunships after it, but the experimental is more than enough to take out the lightly defended base.

Once the middle is secure, you can press the attack onto the main base. However, the enemy will soon start to send off-screen reinforcements to attack. To defend against them, build a perimeter of anti-aircraft and point defence to cover the sides of your main base.

There are three power substations you need to destroy, as marked on the map. These substations have anti-nuke capabilites, are shielded and contain several anti-air turrets. However, they can be easily destroyed by a simple bombing run, or by constant pummelling with artillery.

For each substation you destroy, the enemy will retaliate with an experimental, leading an army of ground units. You can destroy these experimentals before they attack, saving you a bit of trouble. When all three stations are down, attack the main power station to win the campaign.
