- Join us at the Steam PvE Survival Crafting Fest! 🚀 - 1 September 2026
Hello Mars Survivors! 👋 We are thrilled to announce that 687 Days on Mars is officially participating in the Steam PvE Survival Crafting Fest Since your primary enemy in our game is the harsh, unforgiving environment of the Red Planet itself, we couldn't think of a better event to showcase our project. Whether you are carefully managing your oxygen reserves, building your first hydroponic greenhouse from scratch, or exploring treacherous terrain in your rover, every decision matters. 🎮 Play the Demo! If you haven't already, now is the perfect time to jump in. You can download the free Demo directly from our store page and see if you have what it takes to survive. 🗣️ We Want Your Feedback We are actively developing and polishing the game, and your voice is crucial to our process. We’ve set up two places for you to share your thoughts, report bugs, and drop suggestions: 📖 DEMO | SUGGE…
- A Normal Day on Mars - 31 July 2026
Hello Mars Survivors! 👋 Over the last few weeks, we've been focused primarily on testing, balancing, and polishing the game to make your experience on Mars as smooth as possible. 🛠️ But that's not all! We've also been hard at work expanding core gameplay with new events, a building damage system, UI improvements, inventory upgrades, and a few other exciting features we're happy to share today. 🌌 Dynamic Planetary Events 🌪️ Mars is becoming even more unpredictable! We now have three types of events in the game: cold snaps, sandstorms, and solar storms. Each of them can occur with different intensity depending on the season, and each one affects the environment in its own way, creating different challenges for survival. For example, solar storms increase radiation, so staying outside the shelter or going on expeditions can be more dangerous than normal. Solar storms will have three le…
- Moving Across Mars! - 23 June 2026
Hello Survivors! 👋 A bright new day on Mars, a perfect moment to check out another devlog! This time we're showing an upgrade to our existing vehicle to make it better suited for Mars conditions and more helpful for longer expeditions beyond base. Mobile Shelter 🚐 After your feedback, we're replacing the current vehicle with a new one that is much better suited to the harsh conditions of Mars. This is no longer just a basic means of transport but a fully functional mobile shelter designed to support deep exploration and long-range expeditions. 🗺️ Inside the vehicle, you’ll be able to charge batteries, refill oxygen tanks, store collected materials, and manage essential supplies needed for building and expanding outposts. It acts as a secure, self-sustaining hub that keeps you alive and operational even far away from the main base. The upgraded system is designed to make longer journe…
- Seasons of Mars - 8 May 2026
Hello Astronauts! 👋 Welcome to the new devlog! Today we're talking about ever-changing Mars, which will not stay static while you are trying to survive in it. Mars is not just one big desert - It is a planet with seasons, weather and cataclysmic natural events that Earth would not survive, but you for sure can if you prepare well enough! Seasons of Mars ☁️ You will experience all four seasons, each with their own changes and threats. Spring 🌸 will have more sunstorms and magnetic interference, Summer 🌻 comes with giant sandstorms capable of damaging your equipment, Fall 🍂 arrives with strong dust winds that will cover your solar panels, while Winter ❄️ will drain the energy of your base with huge temperature drops! Each season will force you to adapt your strategy and prepare ahead of time. You could try to survive everything by reacting, but you will have much bigger chances of sur…
- Time to think Astronauts! - 2 April 2026
Hello Astronauts! Another transmission from Mars comes in… 🧑🚀 As you saw before, Mars will require plenty of endurance and grit from you to survive it. But also some quick thinking and a flexible mind! Conditions can change in an instant, and every decision may carry weight you won’t feel until it’s too late. That is why today we’re introducing the research and technology development mechanics on Mars! You will have to decide what you need, one discovery at a time. So choose carefully! Research Station: Technology Tree 🔬 The first step is to build a Research Station. This is where data from your Mars explorations is processed, and where new technologies are unlocked—related to base expansion, food production, resource processing, and forecasting dangerous atmospheric phenomena. You will have to decide what should be the priority, what you need at the moment to increase your odds! Ev…

No two solo Mars runs are the same—scout smarter, plan bolder, survive longer. Objective Log: Track Your Quests 📓 Stay on top of your survival agenda with the new Objective Log. It lists all active objectives, detailed descriptions, and step-by-step tasks. Whether it's expanding your outpost or hunting rare supply drops…

- Brave New Home! - 17 December 2025
Hello there fresh Martians!👋 Today we are coming with another devlog, this time something more stable and homely, like BASE BUILDING! The most important part of the game, your base. A place that gives you shelter from the violent atmosphere of Mars, storage for everything you find, place where you grow plants and refresh your equipment. 🌌 Everything you do is in some way connected to the base and it is something that will be an important part of your journey not only mechanically, but with the ongoing narrative. 🏠 That is why we implemented base building based on segments, allowing you to build the base in any way you want. Express yourself, find the most efficient layout, preferably with a nice view! 🪟 The inside of the base will fully be changeable. Almost every part of the base is something you can set up yourself, from beds and recharging stations to hydroponics and kitchen. Eve…
