Nothing here.
Until you build it.

Mars doesn’t make room for you. You make it habitable, one careful decision at a time.

Plan the cargo on Earth. Land on untouched ground. Put your robots to work, connect your power, and keep the outpost alive through its first night.

MORE THAN SURVIVAL

Build a future.
Make it last.

The ambition: a self-sustaining civilisation of one million permanent residents. A place with homes, industry, science, and a reason to stay.

The journey begins with robots and reliable infrastructure. Human arrivals, industrial districts, tourism, and the million-resident campaign are planned milestones.

Every choice connects.

Four foundations.
One outpost depending on you.

BUILD / FROM THE GROUND UP

An outpost starts
with a good plan.

Place imported kits within utility range. Leave room around the ship and neighbouring modules, then let your assembly and cargo robots turn a plan into working infrastructure.

  • Solar arrays, maintenance and communications
  • Placement checks before construction
  • Real kits reserved for each project

From a first landing
to a living world.

01 CURRENT FOUNDATION

Robotic outpost

Launch, land, unload, construct. Establish power and survive the first night.

02 PLANNED

Resource independence

Develop local extraction, purification, storage and follow-up freight.

03 PLANNED

A permanent home

Welcome people. Grow housing, food, research and a working economy.

04 THE AMBITION

One million residents

Expand into a civilisation that can sustain itself for the long term.

Your first night matters.

A few decisions on Earth.
A better chance on Mars.

01 / BEFORE LAUNCH

Pack for the mission.

Check mass, volume and cost before you depart. Each ship carries the same manifest, with a limit of 100 tonnes and 400 m³.

02 / AFTER LANDING

Unload in the right order.

Deploy the self-powered unloader, then unload the startup battery and folded charger before entering colony operations.

03 / POWER FIRST

Build before sunset.

Place solar arrays near the charging hub. Add maintenance and communications within utility range to finish the opening checklist.

04 / PROTECT THE RESERVE

Give the robots a rest.

Shelter idle robots before night. This pauses optional construction and helps protect energy for essential overnight consumption.

What can I play in the current build?

The opening robotic mission: Earth procurement, cargo transit, landing, robot construction, power management, first-night survival, local saves and photo mode. The full colony campaign remains in development. Public download details will appear here when available.

Where are my saves and screenshots?

On Windows, look in %USERPROFILE%/AppData/LocalLow/Mars Project/MARS/. Settings provides three manual save slots and rotating autosaves. F5 saves and F9 loads the selected slot; loading pauses the simulation.

Why has construction stopped?

Check for a reserved imported kit, a compatible assembly robot and cargo carrier, available charging capacity, and enough power. A sheltered fleet pauses construction. At critical energy levels, optional work is shed to protect the reserve.

How does Photo mode work?

Photo mode pauses production and lets you preview day, dusk or night without changing operational resources. Use F12 to capture an image. Power controls the actual grid; photo lighting is a preview.

How can I report a problem?

Keep the build version, a screenshot and the steps that reproduce the issue. Visit the contact page for the information to include in a report. Please keep passwords and account credentials out of reports.
