On Mars

1-4 players 90-150 min 8.2 Board Game Geek Rating

Players lead Mars colonization companies, building interconnected structures like shelters, mines, and oxygen factories across multiple rounds. Actions alternate between orbital space station (acquiring blueprints, supplies, technology) and planet surface (constructing buildings, upgrading facilities). Buildings depend on each other—shelters need oxygen, plants need water, mining requires colonists. Victory goes to whoever earns most Opportunity Points when three missions complete.
