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.
Build and upgrade your base, discover new regions, conduct mining operations, retrieve water, generate oxygen, grow crops, fix broken parts, and learn how to survive on Mars!
Build greenhouses, oxygen tanks, fuel generators, connect all the pipes and cables, and remember about proper cable management. Grow your own food.
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.
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.
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.
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...
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!
if your a person looking for a base building game with a great story to it this is the game you want to play. great game for you to stop thinking about life on earth for a small time.
This game is so bad, holes in terrain, nothing seams to work like messages or any info that is helpful while playing the campaign. Not sure when the discovered tablets have actually given me anything, I'm done......
it is a good game but has still a few bugs needs to fix if item dropped on the floor/ground should be able to be picked up not show it doesn't exist even tho very visable and not in inventary! have to restart the game...
I love this game yes it still needs some work, but dang it's a beautiful game.
The Game is good but the game does not run smooth like the fps is bad and you guys can add new customisation to the characters and make the suits a bit heavier
