More than 20 years have passed since Kyle Brennan, test pilot of the X-Shuttle, was catapulted into unexplored space.
Now, take up the role of Julian Gardna, convicted of the theft of a transport ship, and given a second chance. From this point on, the choices are all yours.
In the immersive universe of X2, there are no rules. Return to a life of piracy and crime, build your own trading empire, join the ranks of mercenaries, or become an ace combat pilot, commanding a fleet of starships from the bridge of your carrier. Any path is open to you.
If you wish to, follow the evolving storyline, and take your place among the greats of the universe, or blaze your own path to glory.

But beware. Something is moving in the remote areas of the galaxy.

X2 features stunning graphics, beyond anything seen before in the space genre.
Open ended gameplay allows you to choose your path freely, in a universe that would take you almost 2 days playing time just to fly from one end to the other. Pilot any of over 60 classes of ship ranging from the tiny Argon Discoverer, a one man fighter, all the way to the Teladi Albatross, a huge carrier class ship over 2km long, capable of carrying a squadron of fighters, all at your command.
A complex yet intuitive interface allows complete control of your empire. Be it a trading fleet of merchant vessels flying between the factories and stations littering space, or a fighter wing of deadly Split Raptors.

Make sure that the driver to your 3D graphic card is proper installed and working.
