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

Pre‑Alpha Notice

This page reflects the very first playable version of the game.
