Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“GreenMars: Expedition 744 is built around systems that interact over time: exploration, survival, base building, terraforming, automation, and long term planetary progression. Early Access gives us the opportunity to test those systems in real gameplay conditions, improve them with player feedback, and shape the game around what works best in practice rather than developing everything in isolation.”

Approximately how long will this game be in Early Access?

“We currently expect GreenMars: Expedition 744 to remain in Early Access for around 12 to 24 months. This may change depending on development progress, feature scope, and community feedback.”

How is the full version planned to differ from the Early Access version?

“We plan for the full version to expand significantly on the foundations introduced in Early Access. This includes broader automation, deeper terraforming systems, more planetary engineering features, additional ecological progression, more exploration content, more threats and environmental challenges, and expanded multiplayer functionality. We also plan to continue improving balance, progression, visuals, performance, and overall game feel throughout development.”

What is the current state of the Early Access version?

“The current version is a very early playable foundation of the game. Players can already explore the Martian surface and caves, gather resources manually, place their first machines, begin local terraforming, use early spreader drones, build a first outpost, and encounter the first hostile lifeforms. However, many systems are still in an early state, and a large part of the planned content and progression is not yet implemented.”

Will the game be priced differently during and after Early Access?

“We do not plan to significantly change the price during Early Access. We may consider a small adjustment after Early Access as the game becomes more complete.”

How are you planning on involving the Community in your development process?

“We want community feedback to play an important role throughout development. We plan to gather feedback through Steam Discussions, player reports, community conversations, and playtesting reactions. We will use that feedback to help prioritise improvements, refine systems, and better understand how players engage with the game as it evolves.”

About This Game

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.

  • Many systems are incomplete or subject to change

  • Visuals and gameplay will evolve significantly

  • Features shown may be modified or replaced

There is currently no release date.

This page exists to share the vision early, gather feedback, and begin building the community.

This is only the beginning.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

GreenMars: Expedition 744 is currently being developed as a solo-led independent project.

Generative AI is used as an assistive development tool for some pre-rendered content, visual design exploration, and, in some cases, to assist the creation of certain 3D assets associated with the game and its marketing materials.

The game’s artistic direction, original designs, and core creative decisions are defined internally by human authors and are not generated by AI. AI-assisted tools are used only to support and help accelerate parts of production.

All final content is manually reviewed, refined, and integrated by our studio. The game does not use generative AI during gameplay and does not connect to external AI services in game.
