At last a digging mod. And congrats for the logistical support.
I hope you plan to ad rock "walls" made of minerals. And "aerial" layers of factories.

The wall idea is great, but what do you mean with aerial layers?

I think they meant vertical layers above normal surface. So instead of going down it's going up, like that one Surfaces mod which has both underground (though pretty simple not ideal in it's implement, old mod and all that) and overground layers (on which it's literally empty surface with "sky" tiles you can floor on to have a platform). Though personally I think that would be too much, or warrant it's own mod with mechanics like structural integrity so you can't just have an infinitely expandable untouchable by biters base above ground

Thats not what this mod is meant to be^^
