Coal Duty

Coal Duty is an online 1–4 player co-op extraction horror game. Use proximity voice chat to survive mutated creatures while mining coal in regime-controlled caves to keep the furnace warm.

Mine & Fill Quota

Under an authoritarian regime, you are sent into the depths to mine coal and extract valuable resources. Miss the quota, and the consequences follow you back.

No Loitering

Of course, you may enjoy your free time after hard work. Just remember who provides it.
