About X4: Foundations
X4: Foundations is a space game where you can trade, fight, explore and build your way from a lone pilot into the leader of a vast space empire. You begin with a single ship, then command fleets, manage resources and shape the galaxy through your decisions.
A simulated universe
The universe is fully simulated and constantly evolving. Factions trade, build and wage war independently, reacting to your actions and to one another. Ships, stations and economies all form part of a living system that continues to grow whether or not you influence it.
Build your empire
You can construct space stations, establish trade networks and control entire production chains. A modular system lets you design and expand stations to power your economy, manage supply chains and automate production as your empire grows.
Fight and command
Combat takes place in real time. You can take direct control of your ships or command entire fleets strategically, with tactics and decisions shaping encounters from small skirmishes to large-scale battles.
A universe in motion
- Thousands of ships and stations carry out their tasks.
- Factions build and expand stations.
- Trade routes evolve as the economy develops.
- You can instigate war or broker peace through subterfuge and diplomacy.
