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.”

Performance Update - v0.64.3

There have been enough additions to the game that I felt it was time to go back and make some serious performance improvements. So there are fewer feature updates in this release, but it should make a big difference for some players on lower end systems. Check out the full change log below. Many of these fixes were suggested and tested by our helpful community on our official feedback forums.

  • Significant performance improvements have been made across all gameplay systems. If the game ran slowly for you before, please report back if you see any improvements after these changes.
  • Lighting improvements have been made inside habitats, including windows that now glow brightly from the light of the sun outside. This is most noticeable with the lights in the hab turned off.
  • Added a selector to the navigation screen that allows you to display locations where previous research samples have been collected.
  • The “Withdraw All” option for inventory management now only withdraws the items of the filtered category you are currently viewing.
  • Fixed an issue that prevented players from repairing equipment if they were too close to death.
  • The selected item cursor for inventory management now returns to the nearest position of the last selected item rather than returning to the firstmost item in that inventory. You can now more easily deposit or withdraw items without needing to use the arrow keys to navigate to multiple items.
  • The PRT RTG slot will now degrade similar to the rate of other RTG slots for exterior modules.
  • The “interact” text hint is now properly hidden for the research station in an unpowered habitat.
  • Fixed a bug that caused an incorrect distance indicator for custom objective points that were set inside of a habitat.

Research Achievements - v0.64.2

This month's update is focused on expanding the research mechanics of the game. You now have a new research bench inside each habitat that lets you track your research progress towards four new achievements. There are lots of other bug fixes as well. Check out the full change log below. Many of these fixes were suggested and tested by our helpful community on our official feedback forums.

Change Log
  • There are four new achievements based on mission research progress.
  • There is a new workstation in each habitat called the Research Bench.
  • Similar to the Crafting and Salvaging Bench, you can interact with the Research Bench to see an overview of your research progress for each research category. This can help you track your progress towards the new research achievements.
  • Habitats also now have one center table art asset to add more visual interest.
  • You can now “run” inside the habitats. Interior walk speed is about 60% of the exterior walk speed, which is what it has always been, but interior run speed is now equal to exterior walk speed so that you can move around inside a bit quicker if you want.
  • Fixed an issue causing driving controls to be disabled when using the escape key to close the datapad while driving.
  • Charged backup batteries and oxygen filled canisters can now be used inside habitats.
  • The “Quit” option from the pause menu will now exit straight to desktop after a confirmation prompt instead of returning to the main menu.
  • Fixed another instance where exterior module components were incorrectly spawning in new games causing the diagnostic screen to display blank information.
  • Fixed a major bug with how dust storms were impacting the degradation of exterior module components which could cause irreparable states to occur.
  • Fixed the hab status panel to correctly display the state of the reoxygenator when running on reserve power.

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. Find and drive rovers to help manage multiple habitats.
