Hello, Colonists!
We have some incredibly exciting news for you today. Our team is currently firing on all cylinders putting the finishing touches on the upcoming Major Update 1.1, and we can't wait to show you what we've been building.

🛠️ What’s Coming in Major Update 1.1?
Here is a sneak peek at the core features and Quality of Life (QoL) improvements we’ve been working on, based directly on your reports and community feedback:
Significant Campaign Rework: We’ve thoroughly overhauled the Campaign mode logic and mission tracking. We focused heavily on eliminating critical bugs and progression blockers that prevented players from completing the story in certain scenarios.
Automated Bottle-Filling Rack: tired with clicking on refill button? you can forget about it with our new bottle-filling rack.

Our changelog is growing rapidly (there are so many smaller fixes and tweaks under the hood!), and we will share the full list closer to the update release.

Not just yet. This update introduces a massive number of changes, and we still need to implement a few crucial fixes and test everything thoroughly. Learning from our v1.0 launch experience, we want to be 120% sure that the most critical issues are completely resolved before handing it over to you. As soon as we feel the build is stable enough, we will instantly deploy it to the public_testing branch!
If you would like to have access to builds that haven't passed full tests, let us know in the comments.
Thank you all for your amazing support, reviews, and continuous feedback. We are making this game together with you, and we can't wait to hang out with you during the stream! Every day we are fighting to make Mars a more hospitable and playable area.

Devlog 106: Roadmap to v1.1 – Campaign, Quality of Life and Rebalancing
Hello, Colonists! Since the 1.0 launch, we’ve been hard at work analyzing your data and reading every piece of feedback. It’s clear that while the scope of the game is exciting, some mechanics have become more of a chore than a challenge. For the upcoming v1.1 Major Update , we a
Hello, Colonists!
Since the 1.0 launch, we’ve been hard at work analyzing your data and reading every piece of feedback. It’s clear that while the scope of the game is exciting, some mechanics have become more of a chore than a challenge. For the upcoming v1.1 Major Update, we are focusing on making your Martian life smoother and more rewarding.
The Campaign Rework & Quest Logic
We are currently performing a comprehensive overhaul of the Campaign mode. Our main goal is to eliminate quest-related bugs and progression blockers. We’re restructuring the mission logic to ensure that triggers work correctly and that you always have a clear understanding of your objectives.
Economy & Quality of Life
Based on your feedback, we realized that the end-game often required an excessive amount of repetitive clicking - something that didn't feel like an issue during internal tests but became apparent in long-term play.
Bulk Resource Handling: We are reworking both the UI and game logic to allow players to obtain larger quantities of certain items at once (such as Organic Waste or bottles). We are currently testing the best solutions to make these interactions intuitive and efficient.
Cost Rebalancing: We’ve heard you regarding the high resource costs of mid-to-late game structures. We are significantly rebalancing the amount of Chemistry-related resources required for major projects, such as the ITS Rocket, to make game experience better in late game..
Technical Optimization & Co-op
Faster Loading: Optimization of save-file structures is underway to noticeably reduce loading times.
Co-op Sync: We are deploying a new package of fixes for P2P stability, focusing on better synchronization between the host and other players.
A Scientific Collaboration: Solar Expanse
As a studio dedicated to Hard Science Fiction, we love seeing other teams tackle the challenges of space. Our friends from Game Ops are releasing Solar Expanse, a game that fits perfectly with the spirit of space exploration.
To celebrate their launch, we’ve teamed up for a special "Martian Expanse Bundle". If you enjoy deep systems and space management, you can check it out here:
View game page
What’s Next?
Right now, we are rigorously testing these changes to ensure that the version you receive is as polished as possible. Once we are confident in its stability, we plan to make it available on a testing branch for you to try out before it goes live for everyone.
We truly hope these improvements will help regain your trust and change the minds of those who felt overwhelmed by the game’s initial hurdles. Stay tuned for upcoming devlogs where we will share more detailed information and changelog!

Edit: this update was now switched live to default Steam branch.
Hello Martians!
We’ve been a bit quieter than usual over the last few days, but that’s only because our team has been working tirelessly behind the scenes. We took a short break from releasing smaller daily hotfixes to focus on deeper, more complex issues that required significant code changes and more testing. The result is this larger patch, which brings a substantial number of improvements to the game.
For everyone interested in details, the whole list of fixes and improvements is at the bottom of this devlog. We also wanted you to read a few tips and information, which could be useful, especially if you are new to Mars.
Remember to make a backup of your saves if you switch to public_testing branch.
A Quick Guide for Colonists: Knowledge is Power 🔴 We’ve noticed many reports and reviews regarding mechanics, that are explained within our built-in learning tools. We’ve even seen players change their Steam reviews after discovering where to find this information!
Before you feel stuck, please check out these resources:
Video Tutorials: Accessible via the Escape Menu, or by pressing H, when a popup comes up. These include videos on how to handle core systems. They were designed by the people who know the game best to help you master the Martian environment.
Tablet Knowledge Tab: Your tablet contains a massive FAQ and Knowledge Base. From building details to survival tips, it’s the guide for any starting colonist.
Important Gameplay Tips:
The Grid System: We’ve received reports about pumps or transformers not having inputs when placed on a steel grid/ramp. This is by design. The grid itself acts as the conduit, collecting and distributing resources from beneath. You don't need manual inputs for devices placed on the grid; production goes directly into the infrastructure. To transfer resources and energy outside the grid, you have to build pump splitter and transformer. We’ve added visual updates to the models of those devices to make this even clearer.
Safe Cooking & Experimentation: You don’t start with a list of recipes, but don’t let that stop you! You won’t lose ingredients (like water, salt, or potatoes) during experimentation if the parameters or vegetables aren't mixed right. Simply add an ingredient and click "Start Cooking" to see potential recipes.
Organic Waste & Chemistry: To keep your Chem Lab running, remember that Composters and Trees are your best friends. Especially in the later stages, trees provide a massive amount of Organic Waste needed for advanced reactions. Remember also about resources, which can be obtained from Abandoned Outposts - those are great resources not only for building materials but everything else you need for survival on Red Planet
Kilopower&Heavy Suit Tablets not working: this is due to a problem with next campaign mission not triggering, the campaign missions will be fixed in the next updates. This is not a bug with tablets, this is caused by not yet fixed campaign bug
Chemlab - there’s no experience points for chemistry, every reaction is unlocked on the table, tablet only shows what’s unlocked.
Occupy Mars is a complex game, and we know the learning curve is steep. We wanted you to have fun discovering your own path to survival, but remember: you have the necessary information in the Tutorial and Knowledge menus. Even Mark Watney was using the manuals while trying to stay alive on the red planet 🙂
We also encourage you to join our Discord server or the Steam Community. There are many veteran players there who are eager to share their tips and knowledge about surviving on Mars.
We Are Listening We want to be clear: we are still hotfixing and we aren't stopping here. We hear your voices, we see your reports, and we’re gathering all the feedback you share on Discord, Steam, and social media.
While we are unable to reply to every single message individually due to the massive volume of feedback, please know that nothing is ignored. Every report is documented and passed directly to the developers. We are working around the clock to bring Occupy Mars to the level of polish you deserve - and the state we envisioned for our 1.0 launch.

Hello, Martians!
Quick Update: Patch 1.0.5 is Live! 🚀
We’re keeping the momentum going! Our team is still pushing hard with daily hotfixes because we’re fully aware that there are still bugs to squash. Patch 1.0.5 is now live, focusing on stability, quest flow, and some much-needed rebalancing.
What’s in this update:
Chemistry Rebalance (Chlorine): We’ve significantly increased Chlorine availability. It should now drop in larger quantities and can be found in Silicon and Aluminum rocks as well.
Vehicle Stability: We’ve implemented a fix for the Heavy Rover and Truck sinking into or falling through the terrain.
Spotty Parts: We’ve partially resolved the issue with missing parts for Spotty in case of save/load. Note: We’ll be further refining this in the next update to ensure it’s 100% solid.
Quest & UI Fixes: Fixed several cases of the problem with Truck’s location shifting unexpectedly during missions. We’ve also cleaned up several missing icons and small UI glitches.
Note: the problems with target points may still occur, subsequent patches will fix next cases of this bug
Co-op Improvements: Addressed several desync issues and problems occurring during save loading in multiplayer sessions.
What’s coming in 1.0.6?
We know some of you are still experiencing issues with saving or loading specific game states. We are already testing Patch 1.0.6, which is dedicated to fixing these remaining save-related bugs.
The plans for next builds include:
Crushers & Miners: Integrating the new mechanics to allow chemical element extraction directly from these machines.
Campaign Overhaul: A series of fixes for campaign quests that should resolve the majority of reported progression blockers.
We're aiming to get 1.0.6 into your hands as soon as possible. Thank you for your patience and for being such an incredible community!
See you on Mars!

Hello, Martians!
Quick Update: Patch 1.0.4 is Live! 🚀
As we mentioned before, our team is working around the clock to address the most pressing issues you've reported since the 1.0 launch. We’ve just deployed Patch 1.0.4, which focuses on stability and some of the more frustrating inventory bugs.
Here’s what’s new:
Inventory Restoration: We’ve fixed the bug that caused items to disappear from your Heavy Rover’s inventory when loading old saves. Note: We are still investigating a separate issue where items may disappear from the container attached to the Rover and another one with Rover falling into the ground. Please be cautious with that specific storage for now.
Chemistry Fixes: We’ve likely resolved the issue where Chemical Elements were not properly saving in their designated inventory boxes.
Campaign & Polish:
Fixed several blockers in the Campaign mode.
Note: There are still several other blockers, we are fixing them already.
Fixed various missing translations and tooltips.
Adjusted volume levels for certain voice messages and notifications that were either too loud or too quiet.
What’s next?
Our work doesn't stop here! We are already preparing another patch. We will release it ASAP. We want to ensure that fixing one thing doesn't accidentally break another—Mars is harsh enough as it is!
The upcoming hotfixes we're working on include a rebalance of the Chemistry Tech Tree (replacing nitrogen with chlorine in aluminum rocks, increasing element yields from drilling, and reducing construction costs). We are currently hard at work on implementing element extraction from crushers and miners, along with more campaign fixes and a solution for vehicles sinking into the ground. We realize chemistry isn't to everyone’s taste, but we’re doing our best to make the experience as smooth as possible.
Thank you for your patience and for constantly sending us your feedback. It helps us make the game better every single hour. Once again, we would like to sincerely apologize for any issues this major update has caused and assure you that we are doing everything in our power to address the reported issues. It means a lot to us that despite our mistakes, you are still with us.
See you on Mars!

Mission Status: 1.0 Launch & Immediate Technical Update
Let’s be direct: the 1.0 launch and the initial hotfixes haven't been as smooth as we intended. In the final push for the 1.0 release, the complexity of the project combined with our small team size meant that certain issues slipped through the cracks.
We’re not here to make excuses – we’re here to fix them. We love this project and we’re determined to make it the Martian experience you expect. Our team is currently operating at full capacity to address your reports and stabilize the build. We believe sincerity is what you, as the community expect from us now.
Current Development Priorities
Campaign & Quests - a fix is currently in internal testing and will be deployed as soon as it's verified.
Vanishing Rover Inventory - the culprit has been found, we are resolving this lissue now.
Container Issues we've found the cause and we're preparing fix.
Resource Balance (Chlorine) We hear your feedback regarding the Chlorine grind. We are looking into a quick adjustment of building requirements and other solutions. For the upcoming builds, we also plan to increase yields and redistribute Chlorine across more rock types and, if this is possible for a quick implementation, adding elements for spawning in crushers. We'll be informing you about details
Pro-tip: Remember that the Spectral Detector Tier 2 allows you to check rock compositions, which is vital for efficient resource gathering in the current balance.
Vehicles Stuck in Terrain we've found the cause and we're preparing quick fix aims to stabilize vehicle physics and prevent clipping issues upon loading.
Our Strategy Moving Forward
We are pushing hotfixes as fast as we can safely verify them. Our priority is clear: fix "game-breaking" issues first. Once the foundation is solid, we will immediately move on to balancing tweaks and general polish.
We’re hotfixing the game as fast as we can to get it where it needs to be. Keep the feedback coming; we are listening and we are working.
Thanks for your continued support and for reporting everything you find. You can find us here and on our Discord server.

🪲 Known Bugs
~~There is a bug that makes finishing the introbase impossible~~ (hotfix on the way) FIXED
there may be issues with water or electricity desynchronisation between players in multiplayer in rare cases, especially on grid
rare cases of disconnect for clients when host loses connection while playing or with joining/rejoining of clients
player can’t disconnect if host doesn’t accept invitation in public game
We are planning to fix those issues in the next hotfixes. The standard solution for the most bugs is to save your progress and restart the game. In coop mode the whole team should restart the game. Verifying game files also usually helps with many problems. Check if you have any mods - probably just after update it may not work properly.
In case the problem is not listed here, please report it via in-game F4 reporter (leaving contact so we can reach you in case of need) or send save and log, with the description of the problem to:
[email protected]
Stay tuned for the next news and the release.
As always, thank you for your incredible feedback, reports, and support! ❤️
See you on Mars!

Hello, Martians! 🔴
We have a massive announcement for you today. After years of development, millions of lines of code, and countless dust storms survived by our community, we have set the date for leaving Early Access. Mark your calendars:
📅 v1.0 Release Date: January 30, 2026 🚀
By a cosmic coincidence (or perhaps destiny?), this date marks almost exactly 1000 days since we first launched into Early Access in May 2023. It has been a long, harsh, challenging, and incredible journey.
We have come a long way
Looking back, the game has evolved massively. While our recent focus on the Co-Op update was a huge technical undertaking, we haven't forgotten the roots of the game. We’ve been consistently expanding the world of Occupy Mars throughout Early Access.
Here is a look back at our mission log*:

May 2023: Early Access Launch 🚀
August 2023 - Exploration Update: 35+ new features, 2 new vehicles, Heavy Suit.
January 2024 - Nuclear Update: 20+ new features, Events system, Supply Drops.
August 2024 - Anniversary Update: 60+ new features, Launchpad, Decorations.
December 2024 - Winter Update: Infinite Technologies, Rover Map, Hangar Rework.
November 2025 - CoOp Update: Online Multiplayer & complete rework of core systems.

* (Plus dozens of patches and QoL updates in between!)
🚀 v1.0 is all about CONTENT
We’ve heard your feedback regarding the recent focus on Multiplayer. The Co-Op update built the foundation. Now, v1.0 will deliver the key content update that completes our original vision.
Coming in v1.0 (January 30th):

Spotty the Robot: Feeling lonely in single player mode? A friendly robot dog companion will be available to help you on your journey! 🐕🤖
Chemistry Tech: The Chemlab and advanced Chemistry technologies will finally arrive, adding a new layer of depth to crafting and survival. ⚗️🧪
Vertical Grid Buildings: The long-awaited scaffolding grid system is here! You will finally be able to build vertical structures and complex bases exactly how you imagined. ▦🏬
Multiplayer Polish: Weather sync, remaining vehicles, and technologies in the co-op mode. 👩‍🚀👨‍🚀
Campaign Mode: We are finally bringing all features and technologies together into an improved campaign that you can complete. 🚀
...but that's not all!
Reaching version 1.0 is a huge milestone - it means our original Roadmap will be complete, but it is not the end of the road. It opens the door for us to start working on Console Versions of the game, while continuing to cooperate with the community.
We are still hard at work at implementing the remaining features and fixing bugs, so the next couple of weeks will be pretty intense for us, but we have set ourselves a deadline we are determined to meet.
👕 Official Merch Shop by Tilt
Finally, a treat for collectors and a cool little milestone for our studio. For a long time, we wanted to bring the art from our games into the real world, and many of you have been asking for this too.
Thanks to our cooperation with Tilt, we have launched an Official Merch Shop! If you ever wanted an Occupy Mars Mouse Pad or Floor Mat, they are now available, and we hope that T-shirts and Hoodies will also be added soon. This is handled externally, so our team remains 100% focused on the game.
Check out the collection here:
Thank you for sticking with us for these 1000 Sols. Whether you joined us on day one or just landed yesterday - thank you.
Get your rovers ready. The biggest update in the history of Occupy Mars is coming in just a few weeks!
See you on the Red Planet,
Occupy Mars Team
