Space Haven is a spaceship colony sim throwing you in charge of leading a patched-together crew of civilians in search of a new home. It’s a base building game where players must build spaceships from the ground up tile by tile, create optimal gas conditions, manage the needs and moods of their crew, encounter other space-faring groups, and explore the universe in a self-built haven among the stars.

After cataclysmic events leave Earth descending into chaos, what remains of humanity will have to vacate or perish on a planet they once called their home. Only the privileged ones, those with access to a spaceship or capable of building one, have a chance at survival. These spaceships, temporary havens, are the new Eden for humans venturing out to survive. Lead your crew and explore the universe as you search for a new place to call home.

Space Haven is inspired by games like RimWorld, Spacebase Df-9, Oxygen Not Included and Dwarf Fortress.


Space Haven is a space colony sim allowing for a lot of freedom regarding building. A functional spaceship can be built tile-by tile, giving you the opportunity to shape a spaceship of your own desire. It can be symmetric and streamlined, or an asymmetrical whimsical looking thing. It does not have to look like a conventional spaceship depicted in sci-fi literature, you are free to design your own, the choice is yours!


Space Haven’s core is built around the isometric tile-based gas system, which simulates various gases, temperature and crew comfort on a spaceship. This system is very similar to the one seen in Oxygen Not Included. The gas system combined with humans, plants and facilities all having their own needs and reactions to gas levels create deep and emergent game play. When designing and building a spaceship, you need to secure facilities, optimize crew survival and well-being, but also think about possible future accidents and chaos generated from crew combat or environmental hazards. Gas conditions can be monitored using different view modes.


As a space colony sim game Space Haven takes inspiration from RimWorld and Dwarf Fortress regarding the simulation of needs, moods, personality traits and relationships of crew members. Every crew member has their own history of life before the apocalypse, their past life occupation and hobbies will affect their skills and know-how. Crew members will develop relationships with each other, good or bad. They will want to spend more time with some, while avoiding others. Witness depression, happiness and drama surrounding different crew members as you journey onward towards a new home.


  • Gain a new crew member by finding a hypersleep pod aboard a derelict ship.
  • Have a space burial for your fallen crew member to let other crew members say good bye.
  • Grow plants with bio mass and water recycled from toilets.
  • Eat the meat from a fallen crew member or invader as desperation is high.
  • Watch aliens capture your crew member and plaster him to a wall in their base. Will you go save him or leave him there?
