    About the game

    You settle on Arcadia-7 and turn scattered resources into a network of mines and factories. Rails carry materials between machines, while contracts unlock equipment and production recipes. Leaving the base means finding blueprints and supplies among abandoned sites. Alien creatures attack during these trips and can threaten your machinery. When the star erupts, you need shelter until the surface can recover.

    Up to four players share the work online. You can send a pair out to search for blueprints while the others arrange production and expand the base. Progress depends on both sides of that work, so there is a reason to compare plans before heading off. Expect a lasting building project with regular fights and interruptions, plus quieter time spent adjusting the factory.

      Backs Working in sync, Exploring, Fighting, Getting better, Unlocks and progress, Planning ahead.

      • Working in sync: Indie-Games.eu, January 5, 2026, describes splitting exploration and blueprint hunting from factory construction. The article was read earlier. A 24 October 2026 recheck reached a 404 page, so its content could not be checked again.
      • Exploring: Abandoned facilities and observatories contain blueprints needed for further recipes.
      • Fighting: Frequent encounters and defensive waves interrupt resource work.
      • Getting better: Automation grows in layers without the opening systems overwhelming the reviewer.
      • Unlocks and progress: Discoveries and corporate deliveries unlock more equipment and production options.
      • Planning ahead: The review describes planning supply chains across several bases.

      Backs Laughter and chaos, Story, Fear, Tension and danger, Calm and coziness.

      • Laughter and chaos: The Review Geek, January 2, 2026, updated April 21, describes snarky dialogue around serious survival. Freshly read on 24 October 2026. The review explicitly covers a pre-release Early Access build, so old technical complaints do not establish current limits.
      • Story: The review finds a corporate setup and GAL commentary rather than an extended narrative.
      • Fear: Aggressive spider-like creatures add occasional unease within a survival game.
      • Tension and danger: Fire waves require shelter and enemy attacks can damage distant bases.
      • Calm and coziness: Habitats give shelter between excursions. This supports brief respite rather than a safe overall mood.

      Backs Sessions, Puzzles and figuring out, Time to hang out.

      • Sessions: The Escapist, January 23, 2026, describes continuing factories and contracts rather than isolated rounds. The played January Early Access body was freshly read on 24 October 2026 and is used for the recurring loop rather than current content ceilings.
      • Puzzles and figuring out: Production chains and resource contracts require figuring out how machines fit together.
      • Time to hang out: The review describes automation that runs after setup and manageable enemies. Room for unrelated conversation is an inference from that pace.
