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 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.
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.
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.
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.
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.
