What the developers have to say:

Why Early Access?

“We want to give the community an opportunity to influence the development of the INTERSTELLAR PRIME gameplay experience. The sales volume of the Early Access will also determine the overall content of the final product since we are a small indie developer”

Approximately how long will this game be in Early Access?

“Our working estimate is 18-24 months from the public rebuild update. This is an estimate, not a fixed release date. The game will leave Early Access only after the core campaign, controls, performance, onboarding, and planned tactical systems are complete and stable.”

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

“The full version is planned to include a complete story campaign centered on Silas and Remnant City; expanded districts, missions, and characters; polished first- and third-person controls; refined combat; the Overlord tactical-command system; additional zero-gravity sequences; expanded audio and cinematic presentation; and broader controller, accessibility, performance, and quality-of-life support. Scope may change based on what tests well.

The older store page described larger sandbox, base-building, fighter, and fleet systems. Those descriptions should not be treated as current commitments. Only features listed in current announcements and present in playable builds should be expected.”

What is the current state of the Early Access version?

“The current public build contains approximately 30-45 minutes of story content. It begins with a short zero-gravity mining sequence and continues with a first-/third-person ground mission in Remnant City. The build is incomplete and may contain rough controls, bugs, unfinished presentation, and limited content. The tactical-command system and expanded campaign are not part of the current public build unless specifically stated in a new build announcement.”

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

“The Early Access price will remain unchanged during the initial rebuild period. We plan to raise the price as substantial new content and features are released and the game approaches full release. Existing owners will receive normal game updates without repurchasing the base game.”

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

“We will use Steam announcements, patch notes, and the discussion forum to explain what changed, what is currently playable, and what comes next. Feedback on crashes, controls, onboarding, performance, and mission clarity will be prioritized. We will avoid publishing fixed feature dates until those features are close to release.”

About This Game

HUMANITY'S FUTURE WAS BUILT BY MACHINES.


INTERSTELLAR PRIME is a science-fiction RPG in Early Access. Enter Remnant City as Silas Lane, a Robocor technician whose work draws him into a conspiracy surrounding artificial intelligence and humanity's future.

Humanity's largest Martian colony survives inside the shattered remains of Phobos and Deimos. Automated systems keep the city alive, but the society that depends on them is beginning to lose control.

THE UNITY 6 STORY REBUILD IS NOW IN EARLY ACCESS


The public Steam build has been updated to the Unity 6 Story Mode rebuild. Begin the rebuilt story, explore Remnant City, and experience spacecraft and robot-command sequences. This is an incomplete Early Access build, with bugs, rough edges, and unfinished content.

Development continues. The current release is an early portion of the game, not the completed campaign.

A LOOK AT THE UNITY 6 REBUILD


The Unity 6 rebuild brings third-person exploration, spacecraft sequences, and RTS robot command into the same adventure. These screenshots were captured from development gameplay shortly before the September 2026 update. Details may differ from the current build, and visuals, interfaces, controls, performance, and content remain in development.

WALK THE STREETS OF REMNANT CITY


The rebuild takes you through neon-lit streets, industrial walkways, and Robocor assignments. Meet the people who keep the colony running and follow their work into the machinery beneath everyday life.

SURVIVE THE CRISIS ABOARD POSEIDON


The rebuilt opening moves through damaged ship corridors, robot encounters, and an emergency above Mars. The development footage shows the suit's Flux abilities, exterior traversal, and the Theseus control sequence.

TAKE COMMAND OF THE MACHINES


Switch from the street-level perspective to an RTS command view. The recorded rebuild demonstrates service bots and a spider construction bot working through a city infrastructure mission, with unit selection, movement orders, and repair tasks.

Images show the Unity 6 rebuild in development. INTERSTELLAR PRIME remains in Early Access; further missions, systems, and polish are still being worked on.

Please base your purchase on the current Early Access content, not on future promises.
