About this game

Occupy Mars is a complex open-world sandbox survival game for fans of the genre.

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.
Survive and colonize Mars alone or in Online Co-Op.
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!
