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.
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.
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.
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.
Thousands of ships and stations carry out their tasks
Factions build and expand stations
Trade routes evolve as the economy develops
Instigate war or broker peace through subterfuge and diplomacy
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.

Normally I would wait for 1000 hours to post a review, but this game especially in version 9.0, is so awesome I will gladly give it a big thumbs up at a mere 968 hours. Thank you Egosoft!
Absolutely phenomenal game, start off small, grow big. Fly around or manage from the map. It's totally up to you.
The combination of zero feedback on why things fail to work and constant bugs makes this game exceedingly tedious to play.

I didn't care for the flight characteristics. I knew pretty quickly this wouldn't be a game that I would enjoy but figured I would give it another shot. After turning it off the first time I never felt the need to go back. Sadly I waited to long and couldn't refund.
