X4 is a living, breathing space sandbox running entirely on your PC. Thousands of ships and stations trade, mine and produce, all realistically simulated. In this universe, you can grow from being the lone pilot of a fighter ship, to managing a vast empire, commanding your fleets and designing colossal space stations. Transition seamlessly from first-person action, boarding ships and visiting their bridges, to an expansive strategy and management simulation. Choose your own path at your own pace. The decisions are yours. Trade - Fight - Build - Think.

Start your journeyIn X4, you can start your journey from a number of different gamestarts and as a number of different characters, each with their own role, set of relationships and different ships and technologies to start with. No matter how you start, you are always free to develop in any other direction. Focus on exploration, make money with illegal trading and theft, command large battle fleets or become the greatest entrepreneur ever. It's all up to you to decide.Fly every shipX4 allows you to fly all ships personally. From small scouts over a wide range of ship classes up to the biggest carrier, everything can be piloted from the cockpit or an external view. A big focus in the development of X4 has been to achieve a seamless and immersive experience when moving between ships. You can leave a ship, climb down a ladder, walk over the dock of a large space station into another ship you may have parked there and replace the pilot that was working for you just by clicking on his chair.
