HUMANITY'S FUTURE WAS BUILT BY MACHINES.
Humanity's largest Martian colony survives inside the shattered remains of Phobos and Deimos. Automated systems keep Remnant City alive — but something beneath its infrastructure is beginning to move beyond human control.
You are Silas Lane, a Robocor technician whose routine assignment exposes a conspiracy surrounding artificial intelligence, hidden interests, and humanity's place in a post-singularity solar system.
ONE SCI-FI WAR. MULTIPLE SCALES.
INTERSTELLAR PRIME combines story-driven role-playing, first- and third-person action, zero-gravity operations, spacecraft gameplay, and real-time strategy. Move from the streets and industrial depths of Remnant City to battles unfolding around Mars — then step into command as the conflict grows beyond one soldier.

ENTER REMNANT CITY
Explore the colony, speak with its residents, investigate its systems, and follow a focused story through a society that depends on machines it no longer fully understands.
WORK BEYOND GRAVITY
Begin with an asteroid-mining operation outside Mars. Learn to move and work in zero gravity before entering the human world hidden within Remnant City.

FACE THE MACHINE THREAT
What begins as a technician's assignment grows into a conflict with autonomous machines, hidden interests, and consequences that reach far beyond the colony.

COMMAND THE BATTLEFIELD — IN DEVELOPMENT
The Unity 6 rebuild is bringing the long-awaited RTS mode into the core experience, expanding the conflict from personal combat to battlefield command.
The two battlefield images above are work-in-progress footage from the Unity 6 development build. UI, visual effects, unit balance, performance, and content may change. The RTS rebuild is not yet part of the downloadable public Early Access build.
CURRENT EARLY ACCESS BUILD
The current public build contains the opening 30–45 minute chapter: a zero-gravity mining sequence followed by a ground mission in Remnant City. It remains an incomplete work in progress and does not yet represent the scope or polish planned for the rebuilt version.
Buy INTERSTELLAR PRIME for what is playable today — not for future promises.
