Total Annihilation - Against Arm (Core Campaign walkthrough)

lvl 11: Your resource-hunger is overwhelming. Put solar panels on your island wherever you can, build metal mines as soon as possible, also the geothermal plant. Than continue the process with zounds of metal makers (transforms energy to metal). This will still not be enough. Oh, and you better make a row of missile towers too just to be sure.
So what you still need is MORE resource, thus build a tidal wave farm on the north side, a shipyard at the south, than an advanced shipyard (shall I mention a water-radar is needed too?), and start to produce both submarines and the giga-ships (warlord). Oh, before you make the warlords, make 2 missile ship there too, they'll be important.
If you made it this far (you should if you don't move from your very shore), you should start launching missiles on targets and prepare for an anti-strike of a ton of "small" ships + submarines. You should be able to clear this if you have 2-3 warlords (submarines comes slightly faster). Be prepared as the AI may start to send some ships to the north circumgoing your troops - prevent this at all cost. Also with this first anti-strike will come some missile-ships from the enemy, so roam after them ASAP.
But don't rush too ahead, else you'll face enemy planes. Heck, it is better to start creating your own fighter-planes purely for anti-airforce as your ships did cost a fortune and you don't want to loose them, and you'll probably be away from your base a little. And those enemy-planes are slightly bigger than basic. Still, 5+ fighter jets should work.
After this mess you should dominate land and air, so there is only the enemy island which your missile-ships should clear from most stuff - anything that moves. Do not hurt what moves, that can be THE Zeus. Send in your Commander fully repaired clearing the remaining structures and bots, and capturing the Zeus which WILL shoot back, so have enough HP.

lvl 12: Hopefully the last water-level.
Yes, it is. The obvious problem is you have like 0 space. But you should realise you have access to very high level of technology, so start with 5 solar panel andmines to cover your basic need (add more when you need), an energy storeage + metal storeage, than a k-bot lab to have builders which can make geothermal plant for you.
When this is made build advanced lab and change all mines to moho mines.
After that your immediate goal is a nuclear reactor. Yes, you'll produce mass amount of energy.
When it stands you need 4 things: shipyard, another nuclear plant, zounds of metal makers, and basic defense, what means like 5 missile tower covering 2 plasma tower (both made by basic construction bots, remember). With these your initially few ships will have a nice support to destroy the arriving enemies (fortunately they aren't many).
When you have a shipyard add advanced shipyards to it, and start producing submarines and warlords like no tomorrow. Some missile ships are also nice.
When you feel confident, start an all-out attack. A troop of 10 warlord will disintegrate practically anything (if they have submarine support, as they can not shoot under water).
