Coal Mine

The Coal Mine is an Outpost found on the World Map which provides a finite (or infinite) supply of Coal.

Repair and output potential

After discovery on the World Map, the Coal Mine must be repaired before it can be utilized. The Coal Mine extracts resources from a limited deposit (or unlimited, if selected in the world settings).

Resource extraction

In order to produce any output, the Coal Mine must be manned. Each outpost can support a variable amount of shifts, depending on the level of the outpost.

Output (per shift)	Cost (per shift)	Total deposit
9 / 20 (27 / 60 )	25x Workers 0.5 Unity per month Maintenance 12 / 60	450.000x
