X4: Foundations

Start Small. Command Everything.

Your journey begins with a single ship - but what you become is up to you.
Trade, fight, explore, and build your way to power as you grow from a lone pilot into the leader of a vast space empire. Command fleets, manage resources, and shape the future of the galaxy through your decisions.

A Living, Simulated Universe

The universe of X4 is fully simulated and constantly evolving.
Factions trade, build, and wage war independently, reacting dynamically to both your actions and each other. Every station, ship, and economy is part of a living system that continues to grow - with or without your influence.

Build Your Empire

Construct space stations, establish trade networks, and control entire production chains.
Design and expand your infrastructure using a modular system, building stations that power your economy, manage supply chains, and automate production as your empire grows into a self-sustaining powerhouse.

Fight and Command

Engage in real-time combat and take direct control of your ships - or command entire fleets strategically.
From small skirmishes to large-scale battles, every encounter is shaped by your tactics and decisions.

A Universe in Motion

• Thousands of ships and stations carry out their tasks
  
• Factions build and expand stations

A Universe That Keeps Evolving

X4: Foundations continues to grow with major updates and expansions that introduce new systems, mechanics, and opportunities for players. Make the universe your own alongside a thriving modding community.
Whether you’re returning or starting fresh, there’s never been a better time to build your empire.
