Occupy Mars is a highly technical, open world, sandbox game about Mars colonisation, inspired by the most promising technologies and companies who work towards the goal of becoming a multi planet species. Build and upgrade your base, discover new amazing regions, conduct mining operations, retrieve water and generate oxygen, grow crops, fix broken parts, learn how to survive on Mars!

Have you ever dreamt about visiting Mars? We always did! There are so many things to see and discover on the Red Planet, so many exciting technologies to be created, so many challenges to overcome! Humanity can do this and become a multi-planetary civilisation!

Build and upgrade your base, make sure that there is enough water, oxygen, power and food to survive. Build greenhouses, oxygen tanks, fuel generators, connect all the pipes and cables, remember about proper cable management.

Fix broken parts using realistic electronic components and tools. Learn basics of smd, soldering, using hotair, electronic measurement tools and all the details necessary to fix your equipment.

Explore different regions of Mars in search for valuable resources, discover mining sites and find the best place to build a city. Remember that you need to find a relatively levelled area with good access to underground water in place where temperatures don't drop too much during the night.

Experience open world, sandbox game with realistic day / night cycle and overcome real challenges that colonists have to face. Build solar arrays and batteries for energy storage, upgrade them and find the optimal way to power your colony.

Occupying Mars is not always fun and games. Sometimes things will explode, break or go not exactly as planned. Learn to cope with "Rapid Unscheduled Disassembly". Sometimes you have to really act quickly before you run out of air, food or energy.

Upgrade your vehicles and equipment in your garage. Organise your workshop and modify your rover. Change crane hydraulics, operate the robotic arm, dig for valuable resources, build mining rigs and more...

...but most importantly HAVE FUN on Mars!

Nuclear Update summary


Nuclear Update is now available for everyone on Steam! 🚀

Here it is, the second major update for Occupy Mars, containing a bunch of new exciting features and mechanics - the Nuclear Update! ☢️

This 📝 devlog is a summary of all our work on the Nuclear Update starting from the first publicly available testing versions of the update up to the latest, 0.154.4, which entered the default Steam branch on February 15. 🌐💻

At this point we would like to ✨ thank our community - we wouldn't have gotten this far in the development of the game if it weren't for your commitment. 🙌🌟 All suggestions, bug reports, support and even criticism, are of great importance and value to us. Creating Occupy Mars for you is a great pleasure. 🤝

🔥 Without any more delay, we introduce you to the array of new features that await you in the Nuclear Update! 🔥


To sum up, with the Nuclear Update you're getting:

✔️ Automated miners

✔️ Uranium centrifuges

✔️ Kilopower reactor

✔️ Hacking antennas

✔️ Random events: supply drops,probes and special meteorites fall and sandstorms

✔️ Pendrives with a boost of exp

✔️ Circuit boxes accommodated to store pendrives

✔️ Pump extension

✔️ Updated tech tree

✔️ Refreshed tablet UI + added a vehicle tab

✔️ More historical places to visit

✔️ New languages

and more...

We decided to make the first versions of Nuclear Update available to the public only on test branches - and it proved to be the correct move, as it was not devoid of surprises. 😶

The most serious ones were 🛠️ fixed, hopefully for good, and some of the new mechanics, such as sandstorms, needed to be corrected and rebalanced. 🚑 🩹 However, we are still struggling with supply drops falling underground. We believed that this bug had already been resolved, however, you continue to 📢 report to us that this keeps happening sometimes.

💡 What we're up to now? 💡

Well, we continue to refine the Nuclear Update, that's for sure! Subsequently, our focus will turn to addressing the next most requested alteration – improving game animations and overall responsiveness. 🔧🎮

What's more, work on the co-op goes full steam ahead. First tests have already taken place and we're not gonna lie - it was fun! 🧨

We're also preparing to launch another major update, expect it to appear sometime in the spring/summer.

Furthermore, there are several content updates in development, with hints provided in the graphic below.


If you'd like to see the original devlogs containing full lists of bugfixes we were sharing on our Steam, we've gathered them all together below. 📋 ✏️

As for Epic and GoG versions of the update - those should be ready in a few days as well.

As always, we encourage you to visit our social media and community channels. These are great tools to keep in touch with you, so we can be updated daily with your 💬 feedback and ❗ bug reports and you won't miss any news from us!

This game is truly epic in my opinion. I have an affinity to space sims and survival sims as well, and this one checks off a lot of boxes for me. You've all done an awesome job and it keeps getting better as time goes on. Thank you.

the trouble with this game is that some details seems watered down, does not represent the intricacies of the real technology that game vehicles and suits are based on. i hope more details and a realism revamp for the character models comes. i think the rover is an example of a good representation, but not the larger vehicles, habitats or the suits. thanks for reading my feedback.

Thank you for your feedback! :) We're doing our best to stay as true to real tenchnologies as possible, but we also have to make sure that the game is accessible to players with less knowledge about these technologies. That said, we're in the process of upgrading our engine, which will definitely improve the graphics.

This is the most complete mars experience I have seen yet, the circuit repair mechanics looks amazing.

PD: Tag Elon Musk on Twitter ;3.
