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, research new technologies and send out expeditions to the surface to ensure the survival of your new found home away from home. Mercury Fallen is heavily inspired by games such as Banished, Dungeon Keeper II and RimWorld. While there is no plan for combat, there will certainly be challenges your colonists will face.
