What Is Mercury Fallen?

Manage a group of colonists as they attempt to survive underground on an alien world. Automated machine construction was sent ahead to create the Mercury facility, but something has gone wrong and your colonists awake to find the facility in ruin. Build structures, recover technologies and send out expeditions to the surface to ensure the survival of your new found home away from home.






Dig out and gather resources from the surrounding area to expand and rebuild the Mercury Facility. Place rooms, structures and furniture to refine resources, recover data for blueprints, grow crops and handle colonist needs.

Some structures require constructing specific rooms which are created by placing the required floor.





The Mercury Facility has fallen in to ruin including the mission blueprint data. Set a scientist to start recovering the data at the computer station. Data recovery unlocks new structures, recovery projects and crafting recipes.





Resources, caves, water generation and more are all procedurally generated using a custom seed value when starting the game.
