Coal Duty

Coal Duty is a 1–5 player co-op extraction horror-comedy set in a world where the sky froze over three generations ago and the state kept the mines open. You are a miner sent underground with a crew to mine coal, fill the cart and return to the surface. The mines are full of creatures that eat production teams, and most of you will come back up.

Mine and meet the quota

Each shift takes you into a freshly generated mine. You can push deeper for a better haul, but the danger increases with depth. You do not have to report all the loot you find; miss the production quota, though, and the consequences follow you back. Tickets earned on delivery are the only currency the state recognizes.

Work as a crew

Online co-op supports 1–5 players. Proximity voice chat means your crew can hear you only when you are close, and so can everything else in the mine. Call out a route, warn the others about something in a tunnel or scream; the mine carries it all equally.

Between shifts

Between shifts, you can spend time in the persistent hub, which includes barracks, a workshop and a tavern. A smuggler is also in the restricted area. You can use time between shifts to build an escape plan and sneak into forbidden zones.

Hazards and escape

The mines contain dozens of distinct creatures. Some are blind, some are fast, and some look like coal until they are not. Multiple escape routes lead toward multiple endings; some miners have reportedly escaped, though the state does not confirm it.
