GreenMars: Expedition 744

GreenMars: Expedition 744 is a sci‑fi survival and planetary engineering game where you reshape Mars.
Explore a full planet, build the first systems of a new civilisation, and begin transforming a hostile world from the very first minutes.
A Full Planet to Explore
This is not a flat map.
A fully explorable planet

Seamless surface traversal

Caves and underground networks to discover

Large environments designed for long‑term expansion


Survival and Exploration
At the start, everything is manual.
Move across harsh terrain

Explore caves and gather resources yourself

Expand your operational zone step by step

You begin with nothing but what you can carry.

Terraforming from the Start
Terraforming is not a late‑game unlock.
Place early spreader systems

Create the first visible patches of life

Expand small zones of transformation

The planet does not change instantly.
It reacts slowly, but it reacts.

Automation and Expansion
As your operations grow, you stop doing everything yourself.
Deploy terraforming drones

Extend your reach across the surface

Scale your systems beyond your immediate area

What begins as manual effort becomes a network of systems.


Atmosphere and Planetary Change
Terraforming is more than vegetation.
Use machines to release and process gases

Influence atmospheric conditions over time

Combine systems to amplify long‑term effects

Every machine contributes to a broader transformation.


A Planetary Progression System
You are not progressing through levels.
You are changing a planet.
Local changes appear early

Multiple systems evolve in parallel

Small effects grow into larger impact over time

Mars is not switched from dead to alive.
It is gradually pushed towards habitability.

A Hostile Planet
Mars resists everything you attempt.
And something else is already here.

Planned Features
GreenMars is designed as a long‑term planetary simulation.
Planned systems include:
Advanced automation systems

Orbital and satellite‑based terraforming

Large‑scale planetary engineering systems

Expanded ecological systems

Multiplayer experience
