What the developers have to say:

Why Early Access?

“Random Seed Games is currently only one full-time developer and a few part-time contributors. I want to get as much feedback as possible on the Survival Sandbox gameplay systems while I continue to expand the game and add features in preparation for a Story Mode.”

Approximately how long will this game be in Early Access?

“It is likely that Lacuna Passage will be in Early Access for at least a year before Story Mode is available.”

How is the full version planned to differ from the Early Access version?

“Story Mode is my long term goal, but I will respond to player's interests with the Survival Sandbox. I will be targeting monthly updates that will address bugs and add new features.”

What is the current state of the Early Access version?

“Lacuna Passage currently exists only as a Survival Sandbox, with an emphasis on the "Sandbox". There is no narrative. There is no combat. There are no achievements or leaderboards. This is a very small game with light survival mechanics. The primary activity is exploration. If you are satisfied by "walking simulators" or have an interest in space photography you might find the Early Access version compelling. If you want a more structured and goal-oriented experience you might want to wait until the Story Mode is finished.”

Will the game be priced differently during and after Early Access?

“I may gradually raise the price as I ship new content and features.”

How are you planning on involving the Community in your development process?

“The main reason I am releasing on Steam Early Access is so that I can get feedback from players. I plan to engage with the community on the Steam discussion forums and the official feedback forum that is accessible through the game's main menu.”

  • There will now always be a Haz-Mat Kit found in Hab Gamma.
  • There will now always be a Printer Key found in Hab Gamma.
  • Survival stats like Oxygen, Battery, Calories, etc will now be depleted 20-30% slower, allowing for longer periods of exploration.
  • Habitat storage space has been expanded from a max of 60kg to 80kg.
  • Added menu option for Mouse Sensitivity.
  • Added menu options to disable Camera Bob and Sway.
  • Added menu options to control SFX and Music audio volumes.

Have fun exploring!

Additional Changes in v0.56.1
  • Added a significant amount of contextual information to the Habitat Status Screen including more descriptions of exterior module status with color coding.
  • Fixed a bug causing the Reoxygenator to use too much water to produce oxygen when the Water Reclaimer was offline.
  • Some users may not be hearing music due to a sound driver issue. Starting a new game might have caused you to get stuck in the landing pod because the music would not trigger. You should now be able to continue out of the pod even if the music does not play.
  • Datapad document lists should now scroll properly.
  • Certain controllers and flight sticks should no longer conflict with datapad keyboard commands if plugged in while playing.
  • Fixed a bug causing the game resolution to change when navigating menus.
  • Fixed a bug causing the player to fall below the terrain when exiting a habitat.
  • Distances to objectives from inside a habitat should now be properly reflected.

Additional Changes in v0.56.2
  • Fixed bug that caused discovered map location markers to appear in the wrong locations after loading a save (requires you to start a new game to fix).
  • Fixed bug that prevented you from picking up single items like found solar panels even though you had enough space in your inventory.
  • Fixed bug that allowed you to remove components from exterior modules without worrying about inventory weight.
  • You can now access the oxygen and battery transfer screen via the habitat status consoles in the airlock without exiting for an EVA.
  • Fixed a trigger that sometimes caused solar panels to come up as RTGs when clicking on them.
  • Stamina is now representing by a heart rate monitor in your HUD.
  • Fixed bug causing the photo edit menu to be hidden behind the photo view plane.
  • Added sparks to indicate when an electrical component has failed due to being installed with the module power still turned on.
  • More changes to survival balance: It now takes about 1-2 days to die from lack of both food and water (depending on activity). It now takes 2-4 days to die from lack of water alone (depending on activity). It now takes 7-9 days to die from lack of food alone (depending on activity).
  • Added text that describes the time spent while repairing module components.
  • Can no longer run with a portable solar panel equipped.
  • Carrying more than 50kg now makes you "encumbered" which prevents you from running and reduces your walking speed. You can carry up to a max of 75kg.
  • Adjusted the solar panel charging rates and adjusted the reserve power depletion rates for unpowered modules to prevent an exploit.
  • The Reoxygenator and Water Reclaimer modules now run at 10% production speed during the night to reduce the depletion rate of the reserve battery.
  • A full EVA suit battery is now equal to 1/4th of a full hab reserve battery (previously 1/2).

About This Game

You wake in an landing pod, check your equipment, and venture out onto the red Martian soil in search of a nearby habitat. With 25 square miles of the Red Planet to explore and survive, you must gather resources from randomized points-of-interest, supply caches, and other habitats in order to continue your mission. But survival is more than just tracking status bars. Maintaining your life-support equipment is just as important as maintaining your health. Lacuna Passage’s Survival Sandbox will allow you to test drive the core game mechanics in Steam Early Access ahead of the upcoming Story Mode.



Explore a massive terrain generated from actual Mars satellite imagery. With features generated from scans collected by the HiRISE project and details painstakingly designed to reflect the photography captured by planetary rovers, this is as close as you can get to visiting the true Red Planet.



Survive the harsh Martian environment with mechanics based on real health metrics like blood glucose levels, heart rate, caloric intake, and more. You will feel like a true interplanetary pioneer as you conquer the elements.



Capture the beauty of Mars with an in-game photography mechanic that allows you to document your discoveries. Photos are saved to your computer at full 1920x1080 resolution and can be referenced in-game where you can set objective points to navigate back to where the photos were taken.



Interact with the various astronaut technologies through your dependable datapad. You will need to manage inventories, salvage and craft supplies, and repair vital life support systems in order to survive the desolate landscapes of Mars.
