Cave Base ?

[Diemex]

So now that we can build bases anywhere... has anyone tried living in a cave ? Is it doable ?

[Captain Brendig]

Yes.

[Aachen]

Yeah. Landing in a cavern is good fun.

[Gatun]

Yes, below water level and above. Just don't clear anything with your mining gun or terrain manipulator because it will just grow back into your base.

[Guh~hey~hey~♫]

Well... uh... didnt really try to live in it, just wanted to land my starship because I saw an alien monolith at the last moment... but there was an awfull storm going on, with very poor visibility.... and so it ended up like this...

I no longer liked that ship anyway....

Did it on an extreme sentinel world (Dead planet) Works like a charm, super cool!

[humbukkerz]

I'm gonna have to get cracking on a cave base too. Found a gorgeous planet with orange grass, tons of exotic fauna deep water to explore but the sentinels are mental! They literally open fire they moment I get out my ship.
Oh and a cave will protect me from the burning rainstorms that occur every other minute. Why is it the coolest planets are always a total nightmare?!! lol

Of course you "can" build your base near anywhere also in a cave, you can also make your own cave through terrain modification.
BUT you have to remember, that you can only have a max of 15000 (or whatever) terrain edits stored in your save game, and ANY new Base will take some edits even if you put them on near plain land, also I believe ressource node harvesting IS terrain modification.

This means, when you have a nice deep underground/cave base but build other bases / outposts on other planets or mined ressources, this WILL result in terrain, flora, fauna whatever WILL take over your underground base eventually again!!
So be warned.
