Description
Mantle Access Shafts combines active cooling and pressure control to exploit deposits far below conventional mines. Turn superior surveying, extraction, refining, and energy conversion into strategic control of scarce materials.
Benefits
Strategic materials output Empire-wide+3%
Common minerals output Empire-wide+3%
Strategy notes
Completed materials and instruments support finite funded extraction. Raw effect deltas: +3% strategic material output; +3% common mineral output. Existing consumers and combined-effect bounds apply. Fixed extraction infrastructure remains exposed to raiding and supply shortages.
Player hints
Complete every prerequisite before adding research progress. Completed materials and instruments support finite funded extraction. Passive modifiers retain their existing global scope; local mining modes affect only Ground, Core and Asteroid Mines.
