ZO Harbor Customs
Can you survive seven days at sea’s edge — where one wrong decision ends everything?
Welcome to ZO Harbor Customs, a 3D simulation and inspection survival game where every choice counts.
You’re the new customs officer stationed on a remote island port. Each day, ships arrive — traders, farmers, diplomats, and sometimes… smugglers or infected vessels.
Your duty: inspect, decide, and survive the week.
Gameplay
Review ship manifests, check documents, and compare cargo details.
Approve, fine, or destroy vessels based on your judgment.
Enter suspicious ships in first-person inspection mode — explore cabins, spot illegal goods, and uncover hidden dangers.
But beware: one mistake, one wrong ship approved or wrongly destroyed… and your week is over.
Each run lasts 7 in-game days. Every day brings new rules, harder inspections, and unpredictable risks.
Permadeath means every error resets your progress — only the sharpest inspectors survive to the end.
Features
Roguelike survival twist: One false move, and you’re back to Day 1.
Escalating rules: Each new day adds fresh laws, hazards, and inspection criteria.
Immersive 3D view: Step aboard suspicious ships and uncover their secrets firsthand.
Tense atmosphere: A mix of calm routine and creeping horror beneath the waves.
Endurance challenge: Survive a full 7-day week to prove your skill.
