About X4: Foundations
Build a space empire from a single ship through trading, combat, exploration, and station construction across a fully simulated galaxy where thousands of independent factions, ships, and economies evolve with or without your influence. Command fleets in real-time battles, manage complex production chains, and shape galactic politics through diplomacy and warfare in a living universe that constantly grows.
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

65 hours and I feel like I'm just getting started.
This is a great game, even with the awkward UI and auto pilot still not 100%. Having reached 350 hours I have finally got into terraforming, which is a pain although worthwhile. I skipped the last 3 dlc's so maybe I don't have the full experience yet it has been really fun so far. I kinda dread trying to find all of the vaults without using a guide but I'm gonna give it a go. The ability to replay the game so you can change the outcome of some quests is nice. Adding mods to your ships can really make a difference too. The 9.0 update has definitely changed things for the better.
@320'isj hours, I have defeatet my first Xenon destroyer I. A massive attack from my defence srations subs and it melted like butter in the sun. This game gives many challanges, as you chose them. Military, exploration, construction, logistics and trade, a key to success I imagine.
Hardly any tutorial. Forget everything you thought you knew about space games. It seems that the game has a Contrarian AI that makes it seem that if you make a move it is wrong and you have to take many other steps to reach a goal that should be simple. Achievements are overly complicated. You have to have infinite patience and be highly intelligent to play this game. I found myself using google almost every step of the way and it was usually wrong. Other than that it's a great game.
CK3 in Space! Say...can I marry that short blue woman over there? Come with me
After all this time, this game is still absolute, overly complicated, convoluted garbage.
