Screenshots

A universe that carries on without you

Factions trade, build stations and wage war on their own, and react to what you do. Thousands of ships and stations keep working while you watch the map, with trade routes shifting as the economy develops.

You sell ore to a station, and later its finished goods supply a shipyard building for another faction. Leave a border alone and the Xenon may move in. It is a good place to feel small at first, then useful.

From one ship to production chains

You fly, trade and take jobs to earn the first credits, then put them into stations and ships that earn for you. Stations use a modular system, so you add docks, storage and production modules to shape supply chains.

Set up miners to feed a refinery, link the refinery to a factory, and let freighters move goods between them. Get it right and the whole loop runs while you are three sectors away, haggling over the next module.

Fly it yourself or send the fleet

Combat runs in real time. You can take the controls of a ship for a small skirmish, or sit back and give orders to whole fleets before a large battle. Tactics, ship choice and positioning decide how it goes.

You can also push toward war or peace through subterfuge and diplomacy, if shooting is not the answer that day.

A long sandbox with room to tinker

There is no set path from lone pilot to empire boss. Explore sectors, run trade networks, automate production, command fleets, and keep expanding across systems added by updates and expansions.

The game keeps growing with major updates, and modding support lets you reshape it further. Expect a slow build: one save can last hundreds of hours, and the real endgame is a self-sustaining economy that funds whatever you try next.

Good to know?

How do I begin in X4: Foundations?

With a single ship. You explore sectors, trade goods, take fights and odd jobs, then reinvest in more ships and your first station. From there you expand into fleets, trade networks and production chains until your holdings run largely on their own.

What keeps the universe feeling alive?

Everything is simulated. Factions expand stations, run trade routes, and fight each other whether you intervene or not. Your choices feed back into that system, so backing one side, cutting supplies or starting a war changes what gets built and where.

Can I build stations and automate trade?

Yes. You construct stations from modules, manage resources and set up trade networks across your holdings. Well-planned production chains collect materials, refine them and move finished goods with little input, growing into an economy that supports bigger fleets and projects.

How does combat and commanding work?

Fighting happens in real time, from small skirmishes to large fleet battles. You can pilot a ship directly or issue strategic orders to fleets and watch the result. Diplomacy and subterfuge offer another lever when you would rather shift borders without firing every gun.
