The ability to hire a bunch of construction, or rather, de-construction workers, to dig for you, funneling the materials to a pick-up location on the surface. They would of course require payment. But you could always just train some Penguins and pay them in fish, im sure they would love that!... Just imagine, a bunch of penguins with mining helmets and pickaxes... Who wouldnt want that!
Sounds pretty cool, but why enslave poor little penguins when you could just have robots do the digging for you?
Robots require power, penguins run on fish. What's cheaper? But meh, yeah, sure, mr Mad Scientist, build your army of miner droids if you want, that would be neat as well Penguins was just one suggestion as to what the mining crew could be
Sounds like Dead Space! We should have Isaac make an appearance and help you kill space zombies! Don't mind me, I'm just wishful thinking here!
