Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.43/day in the week to Aug 24 → 1.29/day in the week after.
Too few observations to say whether a discount moves this store's chart at all: across the last 30 days Steam · Top Sellers · Poland has just 18 day-to-day chart moves that followed a price cut, against 2,498 that did not. We are publishing the count instead of a direction — 20 is the fewest we will draw a conclusion from, and price collection outside the United States began on 6 August 2026.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About


Occupy Mars is a technical, open-world sandbox, survival game about Mars colonization inspired by the most promising technologies and companies that are working towards the goal of humanity becoming a multi-planet species.
Explore different regions of Mars while searching for valuable resources, discover mining sites, and find the best place to build a city. Remember that you need to find a relatively leveled area with good access to underground water in a place where temperatures don't drop too much during the night.

Build and upgrade your base, craft equipment, mine resources, produce water, oxygen and food, explore an open world, and repair complex machinery in a technical survival sandbox.

Manage your energy production and build your electricity grid. Make sure that there is enough water, oxygen, power, and food to survive.

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

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

Build greenhouses, oxygen tanks, fuel generators, connect all the pipes and cables, and remember about proper cable management. Grow your own food.

Experience an open-world sandbox game with a realistic day/night cycle and overcome real challenges that colonists 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 easy. Sometimes things will explode, break or not go 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.

...but most importantly HAVE FUN on Mars!

Jeu attirant mais finalement très decevant. Des bugs graphiques reguliers et aléatoires viennent perturber le gameplay. A cela s'ajoute le problème le plus important : Les différents tutos fournis dans le jeu sont bien trop généraux et aucune explication ni guide n'est fourni au fil de l'aventure pour savoir comment monter telle ou telle machine et pourquoi ca ne fonctionne pas. On pose une machine et on ne sait pas pourquoi le jeu refuse de la poser ici ou comme ca. Des bugs aléatoires et incomprehensibles apparaissent ça et là. La disitrib d'elec, d'eau et d'oxygene et ok et le lendemain on sait pas pk, on se retrouve avec -15°C dans les batiments tjs alimentés. Aucune explication ni guide. Les parties bac à sable et co-op sont deux modes totalement independants et nous n'avons pas la possibilité de retrouver une partie bac à sable en mode co-op. Les options de configuration en mode co-op sont inexistantes. Je ne recommande absolument pas ce jeu. Et au lieu de chercher à faire des réponses bateau aux joueurs comme moi qui ne sommes pas satisfait du jeu, je pense que les dev devraient d'abord finir par terminer le jeu parce qu'actuellement ce n'est pas suffisamment terminé sur de nombreux points pour être considéré comme version final ( 1.014). C'est un jeu encore en bêta à mon avis. Des baisses de Framerate de 90 à 5 FPS, Des pb aléatoires graphiques, des guides incomplets, manque d'informations pendant le jeu ... Un jeu en version 1.0 est censé être un jeu pleinement operationnel et les seul qq bugs doivent rester et être corrigés par la suite. Là on est sur de la bêta ...

Liebes Entwicklerteam bitte bearbeitet den Koop Modus weil es macht kein spaß mehr ständig das Spiel neu zu starten wen irgendwas verbuckt ist (Rover der Greifarm sowie der Bohrer muss echt überarbeitet werden, der bohrer ist auch viel zu Grob beim bohren das die Felsen Zerplatzen in Koop ) Die stats bei der Saatgut ist meistens nicht einsehbar ,nur wen man wieder aus den Inventar raus geht und wieder rein dann sieht man sie wieder ,teilweise kann man garnicht in Marstruck einsteigen dann muss man wieder das Spiel neustarten und wen man das gefühlt 30 mal machen muss nimmt ein das den spielspaß ,also bitte den Koop nochmal gründlich überarbeiten . Das Spiel ist eigentlich nicht schlecht macht auch spaß und ich hoffe das erstmal das der Koop Modus überarbeitet wird und irgendwann mehr content kommt
Has a game breaking bug that stops you being able to progress the story, the devs are aware of it and are working on it. The bug is to do with not being able to fix the truck. The tutorials are a bit lacking and there are still other minor bugs. Overall this "1.0" release should still be classed as early access. It's quite discouraging that there is such a huge bug that could have easily been tested by playing maybe 10 minutes of the game (if you skip tutorials and speedrun to the truck). It seems like 1.0 was rushed. I cannot recommend this until the truck bug is fixed. Otherwise it has great potential. Edit 04/02/2026; Okay, as of 1.0.5 the mission has been fixed. While I still stand by the comments that this game should not be "1.0" release (the full version, not alpha or beta accoring to SemVer at least) I can now rocommend the game with the express warning to new players that is it is still buggy and some stuff doesn't feel quite as good as it could. I have some stutters and full freezes every now and again however I am on Linux running through Proton so I will give the benefit of the doubt. Note for the devs: Thank you for the response to the review and owning the fact that you made some last minute decisions that broke certain stuff. I am a dev, I understand those pesky regressions that come through when you change one seemingly unrelated thing. As I said in the original reveiw, I see the potential and look forward to what you do with this game.
the game is fun but OH GOD AVOID THE STORY LIKE THE PLAGUE ITS SO FULL OF HOLES. 1 : what kind of idiot launches a rocket mid dust wall from storm rolling in? 2: you are soldering without a helmet and knocked unconciouss 3: you wake up with the helmet on?? 4: on the escape your way is blocked by a interactable object blocking the path you have to push that is to the SIDE OF A UNINTERACTABLE OBJECT blocking like 70% of the path, i only noticed its interactable when I went past it for the 4th time. 5: the LEVERS FOR THE DOORS AFTER ARE HIGHLIGHTED AUTOMATICALLY BUT THE STUPID GAS BLOCKING THE PATH ISN'T?? 6: when you jump torwards the escape capsule on the small launcher rocket the inside are full of dust and empty aside from a fully dusted crate. the cutscene to launch the rocket starts before you even close the door so it looks kinda like your launching with the door open. 7. THE EMPTY CAPSULE UPON LANDING IS SPOTLESS AND FULL OF TOOLS AND MATERIALS AND EVERYTHING YOU GOT FROM THE PREVIOUS CHAPTER IS GONE SO APPARENTLY I MADE SURE TO DUST THE CAPSULE INSIDE AND OUT AND CLEAN UP THE PLACE OUT OF BOREDOM AND THREW OUT LIKE TWENTY EXTRA PACKAGES OF FOOD AND SOME AIR BOTTLES CAUSE THEY RUINED THE FENG SHUI OF THE CAPSULE BEFORE LANDING I GUESS?!?!?! OH! wait its all in the storage crate that I had in my inventory, so now I got TWO grinders. which would not be a problem if they had been hanging on the walls before the cutscene. I like the gameplay, and the controls are acceptable, but oh god the campaign is so attrocious every single of the listed things are just the ones that kicked me out of immersion.
Optytmalizacja tragiczna
πολυ καλο στο είδος του.
JEU TRES SYMPA
Ранее я не советовал эту игру. На данный момент отзыв меняю. С моей теперешней точки зрения - нужно пересилить первые 12-14 солов вживания, дальше будет нормальная песочница. Собираешь разное, строишь базу, управляешь энергией, водой, кислородом выращиваешь картошку и т.д.! Что-то вроде мема "Я Вас не звал, идите на ..." - За 550 руб даже очень ничего. - Не вылетает, ( пока ).
amazing game really fun and cool
Старт вышел не очень хороший. Но разработчики молодцы быстро все исправляют. Спасибо. The start was not very good. But the developers are great and fix everything quickly. Thank you.
