Tl;dr
Hate going outside and annoys biter ? Need more ore and ore in the base are depleted ?what
Here the deep ore miner that gives infinite ores at expense of enormous power, materials, and size. This deep ore mining simply a big building that have big rod for deep digging the lands. And require recharge with steel every few hours. However this technology need in end game. Where resource will scarce and materials are needed for an9ther research and base expansion. So having this deep bore early are not reccomended.why
So people have isolationist play style without making enemy become stronger and evolving them to destroy our base. Also enrich main base.Recipe :
Steel (a lot of it?
Adv circuit
Concrete
Some irons
Productivity modules
Electric mining drill
Function :
-Unlimited ores mining. So you can isolate yourself agains other threat
-gives 10 ore / minutes
-need 4 Mw / sec
Research requirement :
-between mining productivity research, that require hi tech components (yellow beaker)
