Star Harbor: Space Station

Build a space station that has to actually work. Star Harbor is a production-chain strategy game where every module costs a slot, every sector bends the rules and every charter asks you a new question: how do I make this balance?

★ 96 CHARTERS THAT GET GENUINELY HARDER
Deliver cargo, hold a self-sustaining production rate, run at 100% efficiency with more modules, or finish with a lean station. Sector exams combine several goals at once. After charter 96 the endless Deep Frontier keeps raising the bar.

★ LIMITED SLOTS — THE REAL PUZZLE
Your station has a handful of module slots. Upgrade one strong drill or build a second? Upgraded modules need more power, oxygen and crew than they gain in output. Every third charter opens a new slot.

★ EIGHT SECTORS, EIGHT RULES
Dust Belt drains your solar power, the Ice Ring makes oxygen costly, the Radiation Belt exhausts your crew, the Deep Void shrinks storage... A working station must be rebalanced every time you move on.

★ DEEP PRODUCTION CHAINS
Ore, ice, silicon and gas become alloy, polymer, circuits, fuel and components. Research 72 nodes, unlock 38 module types, deliver contracts in eight markets and fall into the singularity for a permanent multiplier.

★ LIVE LEADERBOARD
Compete with real captains — all time and this week. Only your nickname and progress are shown.

★ ALWAYS A NEXT GOAL
Daily supply drops, three daily missions, a weekly cargo run, captain levels, achievements with rewards and station liveries. Your harbor keeps producing for up to 8 hours while you are away.

Fair and optional: every charter can be completed for free. The game shows ads; optional purchases (Remove Ads, Starter Pack, Admiral Pass, Quanta, Harbor Vault) add convenience — never required. No subscriptions.
