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.”

Controller Support Update - v0.6

v0.6 focuses on making the control options much more flexible. This required a complete rework of the input system in the game to support most PC-compatible controllers and full key remapping options. This continues my current pattern of alternating major updates between gameplay system additions (like the previous pop tent and dust storm updates) and quality-of-life additions (like this one). Check out the full change log below.

Change Log
  • Controller support has been added for most dual joystick controller types.
  • Keyboard and controller button remapping is now available via the Controls option menu.
  • Increased frequency of dust devils.
  • Fixed bug that caused hab status panel to display information from a different hab.
  • Fixed production levels of oxygen and water modules relative to the impact that broken components should have.
  • Changed locomotion settings for moving up and down slopes and while jumping.
  • Fixed issue where reserve battery could be charged slightly over 100%.

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.

Pop Tent Update - v0.59

v0.59 now provides a new way for you to escape the elements of Mars. Emergency Pop Tents are now deployable items that you can enter to protect yourself for dust storms, eat while on EVA, and save your progress by sleeping.

The rest of this update is a little lighter on content than usual because I have had to spend a lot of time updating the game code to be compatible with the latest version of Unity. Unity required a security update and I figured it would be a good time to also just update everything to the latest version. I've gone from Unity 5.3.8 to Unity 2017.1. This required a ton of little fixes to ensure everything will work as it did before, and I'm still not entirely sure that everything will be functional. If you find something that seems out of place or inconsistent with how you remember the game working before, please let me know via the official bug reporting and feedback forum.

Change Log
  • Updated engine to most recent version of Unity for performance and compatibility improvements.
  • Numerous bug fixes for issues related to Unity version update.
  • Loading of interior and exterior scenes should be faster.
  • Habitat interior lightmapping has been improved.
  • Terrain dynamic shadows have been improved.
  • Fog distance and blending with horizon have been improved.
  • Added deployable Emergency Pop Tents that allow you to take shelter from dust storms, eat consumables, and save your game while on an EVA.
  • Remote outposts with permanent pop tents are also useable now and they produce their own ambient oxygen so your suit reserves will not deplete while inside.
  • Added quick reference panels by interior airlock doors to see the status of your exterior life support modules at a glance while inside a habitat.
  • Equipped portable solar panels will no longer charge your suit battery while inside an airlock.
  • Dust storms now properly impact exterior module power production based on proximity to the storm’s epicenter.
  • Dust storm particle effect visibility due to proximity to storm epicenter has been adjusted.

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 v0.59.1
  • Fixed an exploit that let you craft oxygen filled canisters even when there was not enough oxygen in the reserve tanks.
  • Supported refresh rates are now listed in the resolution settings (in the previous update they appeared as repeated entries of the same resolution in the list).
  • A water reclaimer unit at the northern habitat location has been moved slightly to prevent the water tanks from being hidden under the terrain.
  • The minimum solar power during a full dust storm is now back to 15%.
  • Fixed a bug that was drawing too much power while sleeping causing negative reserve power values.
  • The inner habitat door can no longer be selected through the wall.

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.
