On a fateful day, test pilot Kyle Brennan made a jump from earth into the X Universe with the iconic Xperimental Shuttle. This set in motion the events in X: Beyond the Frontier, which was released in 1999, and started the X series of games.

This year marks the 25th anniversary of the X series!

For two and a half decades we have explored space, immersed ourselves in lore, managed economic empires, and fought in epic battles, through several main game releases, numerous add-ons, expansions and major updates - and we are far from done!

We would like to take this opportunity to reminisce a little about the past 25 years of X games, and have prepared a video in which Bernd Lehahn, creator of the X Universe, takes a flight down memory lane. Enjoy!
