I just picked up Factorio (which I'm enjoying so far), and I dug around in Steam, the Wiki, and the forums here, and I can't really find information for the specific campaigns (or I may not be looking in the correct places in all the above?), and I'm having some trouble with a specific one.
I've read in a few places that only the first 2 parts of "New Hope" are done... is that still true, and the rest is just a "shell" campaign, and why I'm having troubles, and I should just skip it and go right to freeplay at this point, as I did the tutorial and first 2 parts of New Hope?
I've gotten to the "New Hope" Campaign, Level 03, where you are trying to get the to the computer. I managed (after many restarts and frustrations with figuring out exactly some of the mechanics and what I was supposed to do, without getting my poor little buggy blown up in 30 seconds) to blow up the "small" outpost in the "north central" part of the map. I killed the outpost, but my next directive is "there are no resources here; build a specialized base". But there's absolutely no clue as to what said base is supposed to do? Is this just "a place I can retreat behind a lot of turrets and repair?" A place to make more ammo? (that will run out fast, with no resources). A research facility?
Can someone drop me a clue what, exactly, my "goal" is supposed to be here? I'd hate to start building say, a nice turret fortification, and then discover I need to make some sort of specialized ammo....? or a place to do research?
Things in this part of the campaign that led to my questions/frustrations (which may relate to "this part of the campaign may not be finished yet"? or may give someone a clue where my troubles lie, or even feedback on making this part better...):
"north central" led me to believe it was "up" from me on the map where I started, as I had no idea where I was on the map as a whole. Turns out I'm in the northwest corner of the map, and it was just to the right of me. Much buggy damage and frustration trying to find my target. A quest map indicator on the minimap would have helped.

Driving the buggy with WASD keys is incredibly difficult, as the keys are "relative to how the buggy faces", not relative to the map on the rest of the board. This may be a gaming standard (or an engine standard: I ran into the same issue in another game? ), but it's incredibly difficult to drive any vehicle this way, especially in combat. Any tips from more experienced gamers most welcome on this...

The repair items should be on the starting hotkey, with the grenades for this scenario. Or perhaps it's the fact I have great aim for hitting trees?
The arrow indicator for the "destroy the biter outpost" is flashing on the shipwreck, so I threw my grenades there, not on the actual biter nest. While I did actually finally destroy the nest, I had to make extra grenades to do it, because I wasn't going for the correct target. The flashing arrow should first indicate what you need to destroy, not the shipwreck, as I was mystified why I hadn't "killed" it yet, until I finally destroyed the rest of the nest, and was able to click on it and see what it was. You cannot get close enough to do this until the nest is destroyed without being attacked by waves of biters, so I had no idea that was NOT my proper target until the battle was all over (if any of that makes sense?). Once I did it was a D'OH moment...
Any replies to help me get past this one much appreciated...
