Features

  • 96 charters

    Delivery, self-sufficiency, efficiency and lean-station goals, with multi-goal sector exams.

  • Limited slots

    A handful of module slots turns every upgrade into a real trade-off.

  • Eight sectors, eight rules

    Each sector changes power, oxygen, crew, storage or market conditions.

  • Deep production chains

    Raw ore, ice, silicon and gas become alloy, polymer, circuits, fuel and components.

  • Research tree

    72 research nodes unlock 38 module types.

  • Live leaderboard

    Compete all time and weekly; only your nickname and progress are shown.

  • Offline production

About Star Harbor

Star Harbor is about making a station work, not just making it bigger. Drills and harvesters turn ore, ice, silicon and gas into alloy, polymer, circuits, fuel and components, and every module costs power, oxygen and crew. The station has only a handful of slots, so each decision is a trade: upgrade one strong drill or build a second one. Upgraded modules need more support than they gain in output.

Progress comes through 96 charters. Some ask for a delivery, others for a self-sustaining production rate, full efficiency with more modules, or a lean station. Sector exams combine several goals at once, and every third charter opens a new slot. Each of the eight sectors bends the rules: the Dust Belt cuts solar power, the Ice Ring makes oxygen costly, the Radiation Belt tires the crew and the Deep Void shrinks storage, so a working station has to be rebalanced on every move.

Research spans 72 nodes and unlocks 38 module types, contracts run in eight markets, and after charter 96 the endless Deep Frontier keeps raising the bar. Daily supply drops, three daily missions, a weekly cargo run and a live leaderboard give each day a goal, and the harbor keeps producing for up to eight hours while you are away. Every charter can be completed for free.

Who it is for

Strategy and simulation players who enjoy optimisation puzzles and production chains, in sessions that fit a commute.
