Every world is a place, not a menu
Your colony is a planet you can turn in your hands. Watch your refineries, reactors and shipyards rise on its surface, see the debris ring a lost battle leaves behind, and track the moon that forms out of the wreckage.
- Real-time production you can watch climb
- Sector and universe maps in full 3D

What is Hidden Sector Online?
A browser-based space strategy game about holding on to something worth taking: one planet, a working economy, a fleet you built yourself, and every other commander in the universe wondering whether they could take it from you.
What you do out here
Build an empire
Raise extractors, reactors and shipyards, balance power against workforce, and grow one colony into many.
Command fleets
Scout, raid, haul and invade. Every hull has a job, and fuel and cargo decide how far your reach really goes.
Fight for what you take
Win in orbit, land your marines, then hold the world under siege long enough to plant your flag.
Forge alliances
Join forces, share recon and battle reports, run a private forum and chat, and mentor newcomers.
Spy before you strike
Espionage reveals stockpiles, buildings, defences and fleets - the higher your level, the deeper you see.
Climb the rankings
Points, offence, defence and combat boards, each tracking how far you have moved since yesterday.
