Where Roll Authority is headed.

From the free demo to the last launch out of the system. Plans change as the game is built with its players - this page changes with them.

    Free demo

    October 2026 · itch.io

    The first flight. Build a rocket, reach orbit, and set down on Luna - free.

    • Shipped

      Vehicle assembly

      Part-by-part rocket building with stacking, radial symmetry and drag-and-drop staging.

    • Shipped

      Real orbital mechanics

      Keplerian orbits, staging, time warp and a map view with live apoapsis and periapsis.

    • Shipped

      Høm and Luna

      Launch from Høm, make orbit, and land on its moon.

    • In development

      Cut-paper solar system

      Every planet, ship and module in a hand-made construction-paper look.

  2. 1Planned

    Early access

    Steam page purchased · date to be announced

    The supply chain opens: everything you build off-world starts paying for the next launch.

    • In development

      Survey, mine, refine

      Scan worlds from orbit, set down drills, and refine ore and ice where they lie.

    • In development

      Cargo and construction

      Shared cargo holds that weigh out or cube out; structures that cost their own mass in metal.

    • In development

      Colonies

      Habitats, life support, food and the people who depend on them.

    • In development

      Fleet logistics

      Standing delivery routes, so ships run the supply chain while you fly something else.

    • In development

      Research

      A tech tree funded by the science your instruments send home.

    • Planned

      Every propellant family

      Methalox, hydrolox and hypergolic engines, with tanks you can refit between them.

  3. 2Planned

    The evacuation

    Early access updates

    The crisis spreads world to world, and every settlement you build becomes the next one to empty.

    • Planned

      The contamination

      The bacteria follow the evacuees from body to body, forcing wave after wave.

    • Planned

      The wider system

      Precimeter and the outer worlds, each with its own resources and hazards.

    • Planned

      Stations and depots

      Orbital refueling stations and docking-built megastructures.

    • Planned

      Mod support

      Parts and behaviors from data files and plugins - no recompiling the game.

  4. 3Planned

    1.0 - Departure

    Full release

    The generational ship, the warp jump, and humanity's last launch from the system.

    • Planned

      The generational ship

      The largest thing you will ever build, assembled in orbit from everything you have.

    • Planned

      The jump

      A warp jump to the nearest survivable star - and a campaign that ends there.

    • Planned

      Full price

      Early access ends; the price rises from $19.95 to $39.95.
