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