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?

“StellarForge combines modular construction, colony management and ship building. Early Access will help us test how these systems work together during normal play, identify bugs and usability problems, and improve performance and balancing with player feedback. Our priority is to strengthen the core experience before expanding its scope.”

Approximately how long will this game be in Early Access?

“We do not yet have a confirmed date for leaving Early Access. The duration will depend on progress toward our stability, performance and gameplay goals, together with feedback from players. We plan to share development progress and update our release expectations as those goals become clearer.”

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

“We plan to improve the core construction and colony-management systems, refine interfaces and visuals, and expand available content. Further destinations, ship capabilities and advanced gameplay systems are development goals. Their scope and timing may change as we test the game. Development updates will distinguish released features from planned work.”

What is the current state of the Early Access version?

“StellarForge is currently in development and has not yet launched on Steam. The development build includes surface environments for the Moon, Mars and Earth, Moon and Mars orbital environments, modular colony construction and basic ship construction. Systems, interfaces, visuals and balancing are still being refined, and advanced flight systems and new equipment remain in integration and testing. Before Early Access launches, this section will be updated to describe the specific content and limitations of the downloadable build.”

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

“We currently plan to gradually raise the price as substantial content and improvements are released. Any price changes will be announced in advance.”

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

“Players can report bugs, share suggestions and discuss the game through the Steam discussion boards and our Discord community. We plan to publish development updates explaining completed changes, current priorities and known issues. Feedback on construction, usability, performance and balancing will help guide development.”

About This Game

One more room. One more demand on everything keeping you alive.

Build and run a space colony on the Moon and Mars. StellarForge is a single-player colony simulation where each expansion needs more than building materials: it needs air, power, food and people to keep it running.

Build a place people can live

Design modular habitats, connect rooms and airlocks, and lay out the routes between living quarters and work areas. Provide breathable air and thermal control. Leave room for your crew to reach their beds, meals and machinery before adding another production floor.

Plan around temperature and radiation outside. Balance power generation with stored energy, and keep reserves for the long night or a disrupted delivery.

Supply the colony. Look after the crew.

Mine raw resources, grow crops and turn the harvest into meals. Build up manufacturing as your settlement can support it. Every machine needs ingredients, power, workers and maintenance; extra output brings extra demands.

Assign jobs while making room for meals, rest and medical care. Workers gain experience through their work. Another hire can help clear a bottleneck, but only if you can feed, house and pay them.

Expand when you can support it

Assign engineers to labs and choose research programs through Research HQ. Develop surface settlements and orbital facilities, connect colonies with supply routes, and take on settlement and production commissions as your operation grows.

Decide what to build next—and whether the colony behind it is ready.

In development

StellarForge has not yet launched on Steam. Crew routines, long-term survival, saving and loading, performance and interfaces remain under active testing. Ship construction and advanced flight systems are also being developed; previews and development updates may show unfinished work.
