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. 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.”

Dust Storms Update - v0.58



v0.58 marks the major feature addition of randomized dust storms to Lacuna Passage. The best way to quickly experience the new dust storms is to start a new game with the Big Storm scenario detailed below. If you want a quick timelapse of what dust storms look like you can check out this video: https://www.youtube.com/watch?v=AQcqiPImao4

Change Log
  • Added randomized dust storms that can slowly move across the map and impact your visibility, mobility, and navigation functions.
  • Added a survival sandbox scenario select screen with three currently available options: No Dust Storms Mode, Standard Mode with occasionally spawning dust storms, and Big Storm Mode which will start with a large dust storm hitting Habitat Alpha within the first 3-7 Sols.
  • Added small blowing dust clouds over the entire map.
  • Added randomly spawning dust devils.
  • All habitat interiors now have an airlock exit sign to differentiate the two doors.
  • The screen no longer fades completely to black during exterior module repairs. You can now see time pass in your HUD and the cost to your oxygen and battery in accelerated time during the repair.
  • Fixed issue with exterior module resource generation when sleeping for long periods.
  • Fixed issue with RTGs not generating exterior module resources properly at night.
  • Fixed incorrect description of Multitool. Multitools now explicitly mention that they can be used as a Cutting Tool, Building Tool, and Engineering Tool.
  • The objective LAT and LONG is now updated while placing a custom objective in the Navigation app.
  • Fixed issue with some Drill Rover locations not being added to navigation.
  • Fixed incorrect randomization of exterior module component integrity values for the southeastern-most habitat location.
  • Scanner is now automatically disabled when entering a habitat to prevent unintended scanner highlights while indoors.
  • Fixed issue with incorrect habitat resource values being displayed when accessing the EVA suit management screen between two different habitats.
  • Fixed incorrect texture on water reclaimers.
  • Fixed incorrect exhaustion recovery value when consuming water.
  • Sleeping for 0 hours is now allowed as a way to save without sleeping. Was previously only accessible by cycling the time value in one direction.
  • Fixed issue with the starting landing pod changing positions after loading a saved game.
  • Fixed a floating rock at a solar panel discovery location.
  • Fixed issue where some exterior module components were unable to be removed.

Keep in mind that this now makes the weather monitoring functions of the Waypoint Stations worth maintaining since they can warn you of an incoming dust storm and you can track the visibility at each WayStat location with the function enabled via installed fuses.

Many of these changes were prioritized based on feedback provided by players on our Feedback Forum. Help me determine future development priorities by posting your ideas, suggestions, and bug reports there.

Additional Changes in v0.58.1
  • Fixed bug that caused Electrical exterior modules to operate as "On" even when the power switch is turned off.
  • Fixed minor UI spelling mistakes.
  • Fixed bug that occasionally displayed incorrect hab reserve supply values in the suit management screen.
  • All habitats now start with their interior temperature roughly equivalent to the exterior temperature since their heaters have been offline for an undetermined amount of time.
  • Fixed bug that prevented breathing audio from playing before entering the first habitat.
  • Fixed bug that prevented the proper placement of custom objectives in the navigation app.

Survival Stats Update - v0.57



Today's update is an attempt to add some new player progression goals to the survival sandbox including achievements and leaderboards. Check the full change log below.

Change Log
  • Achievements have been added for a range of survival goals.
  • Leaderboards have been added for survival time and distance traveled in a single playthrough.
  • A stats screen will now be displayed upon dying which will tell you exactly what you died from along with comparisons to your previous best run.
  • Increased scanner detection range for standard containers (blue squares) to 300 meters (this distance is not increased by activating WayStats).
  • Crafting an oxygen filled canister now requires 50L of oxygen from your hab reoxygenator tanks.
  • Your EVA suit can now be equipped or removed while inside a hab via the EVA preparation screen (accessible from the habitat status consoles).
  • Your EVA suit will now only be removed automatically upon entering a hab if the reoxygenator has oxygen in the tanks.
  • If the hab reoxygenator is not producing oxygen then you will now more accurately consume oxygen from the reserve tanks while not wearing your EVA suit.
  • The accumulated radiation exposure will now be saved properly.
  • The photo app should function more reliably when deleting photos.
  • The heart rate (stamina indicator) will no longer disappear while jumping.
  • Non-electrical components will no longer throw sparks when being replaced in exterior modules.

Many of these changes were prioritized based on feedback provided by players on our Feedback Forum. Help me determine future development priorities by posting your ideas, suggestions, and bug reports there. See if you can keep your spot on the new leaderboards and collect all the achievements!

EDIT: A hotfix has been applied that has fixed additional issues with oxygen and suit interactions inside of habitats.

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 and survive randomized threats like dust storms.



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.
