About X4: Foundations

X4: Foundations drops you into a fully simulated galaxy where a single ship can become the seed of a sprawling empire. Trade, explore, fight, and build as factions act independently, reacting to your choices and each other. The game blends real‑time combat, strategic fleet command, and modular station construction, letting you shape a living economy that persists with or without your influence.

01 / THE GUIDE

Living Simulated Universe

The universe in X4: Foundations evolves continuously, with every station, ship, and economy forming part of a dynamic system. Factions trade, build, and wage war on their own, creating a backdrop that changes regardless of player actions.

This constant evolution means that trade routes shift, wars flare, and new opportunities appear as the simulated galaxy grows, offering a backdrop that feels alive and responsive.

  • Observe faction behavior to anticipate market changes.
  • Use diplomatic actions to influence the evolving political landscape.

02 / THE GUIDE

Empire Building

Players can construct space stations and establish trade networks using a modular system. Stations power the economy, manage supply chains, and automate production, allowing the empire to become self‑sustaining.

As infrastructure expands, production chains grow, enabling control over entire sectors and the ability to shape the galaxy’s economic flow.

  • Plan station modules for efficient resource flow.
  • Link production chains to secure steady income.
