Check out my achievement guide.

[dart193]

I see a lot of people have problems with Arca, Farbor and some achievements. Check out my achievement guide It is only 60% ready, but main storyline achievements are mostly done. It tries to not reveal plot and i tried to make it easy to navigate. If you did not found what you searched for - come back another hour - i am planning to add guides for at least 20 more achievements today.

EDIT: Guide is 100% complete. You can ask more help in comments or write me personally.
Huge thanks to Mike Mefisto, i almost gave up on Waternaris, but made it thanks to his support)

[Mike Mefisto]

Your Farbor guide is to complicated but for rest. Great work. I see still some work left so hope you will end this good guide.

[dart193]

I am working on it right now - just finished Chanson without killing any gliders and glider factories and is about to share my method.
About farbor: what part do you find complicated? It is the achievement itself that is really hard.

[Mike Mefisto]

You tell people to fly with command nodes and to build forge in place where you have only 1 CN so you have less power.
Then you say you personal did it with 99% so it's tight and leave no room for mistakes and people do them. So something so tricky is not good for guide.
Don't tell people to rush into main island but to shoot down ore ships.

[dart193]

I probably mistyped. It was arca which i did on 99%, farbor was done on 78%. About why forge on right island - because you will be doing assault from upper island. You will be powering your cannons and if forge goes off even for a moment, you are screwed. Not to say how much ammo Bertha requires. About ore ships - you need to destroy emitters first and you will barely have enough energy. I tell people to destroy ore ships when emitters are down so that they can build sniper on power zone. It will be then killing at least 2 ships. Yet what i found that you either need a lot of snipers to bring down a ship every time it goes or simply be quicker. And snipers eat a lot. About room for mistakes - i got these 78% with oh so much mistakes, i could probably do it on 50 but oh god i will not, this isnt easiest achievement.

But i will do some edits and take your advices into account.

EDIT: I edited the guide a bit to explain my actions a bit more and fixed % info.

A few comments.
The Not Going to Vapen achivement. No need to build up a bunch of aether and use that as a weapon, a couple of berthas, especially a couple placed on the power points you get while going through the level combined with 1-2 shields, a few mortars and a few cannons is all that you need to nullify the inhibitor without clearing the top creeper spawn.

As of Apexian you are allowed to build a Forge and upgrade stuff, just not use the weapon on it.

[dart193]

Hoshi, i used aether weapon because i did not manage to do it with Berthas and shields are hard to use properly because mine barely distract creeper at all. Yet when i shot aether gun, i just waited a minute, sent a guppy there, built a nullifier and it was done

About Apexian - thanks for the clarification! I was unsure but better safe than sorry.

Maybe I should make a guide for doing the Farbor mission before the ship gets created... The mehod I used really wasn't all that hard or all that tight with energy or time. I tend to be kinda wasteful with both. :P

[dart193]

If you don't really want to create a guide but to share a strategy, write your strategy here and i can paste it into my guide as a quote and give you a credit.

[DorcasAurelia]

Shields aren't meant to be an absolute barrier, but when paired with a sprayer or pulse cannon they make establishing a landing zone much easier.

[dart193]

Sprayer+shield... interesting combo but does not works on maps without ore. Yet i will try to use that combo more. Thanks!

Still having problems with the :| Area Denial. Unclear if one of my canons hit a glider or something

Keep in mind, you have to do the level without letting ANY gliders die. That means if any of your stuff gets too close to a track, the gliders kill it, thus killing themselves in the process.

Even without actually "killing" any of them, you seem to fail to get the achievement if the gliders kill any of your units either, because they die to do so.

Yeah I got the achievement. Had to keep faar away from them.

Update: done Size matters achievement (metroid mission). Took whole 6.7k symbols so had to make separate section for it. I hope this will help. Now, the Fine wine remains... dammit, it will be hard, but i will still try to do it myself anyway.
Note: i did not checked different strategies for different parts in size matters, so if you think that i made some parts wrong or hard way, please comment and i will probably make an edit.

[Mike Mefisto]

about Size matters.
it's good to do some 'lover' achievement at this map.
At start you should build ore mine and sprayer it's more expensive than 2 cannons but don't use power that is needed badly to defend you from spores at start.
Terp unit to teraform is blocked in this map so good is to get spots for Berthas fast so '12' and '18' at your map should be taken sooner. With so many Berthas in power zones you will clear rest fast.
About creeper cannon. It has good range but there is anticreeper island near. I set cannon close to edge. Beam and guppy back. Cannon shoot my cannon in anticreeper and my main army can get closer not bothered by it. (like taking 12 after 4).
Target '11' has holes and there is place there to land with guppy and 2 units. I used air units (around 14+) and 2 canons with 2 mortars to get '11' clear.

Tips:
shield is good to move up hill
