Hmmmm... It wasn't always like this, humans building colonies on Xen, at first it was a lot different... It all started with the top secret government facility called Black Mesa. Those scientists then stumbled upon teleportation technology and sadly, discovered Xen.

They say that during the invasion of Earth, all of the XET members were killed in the chaos. I, Bill Freeman, former XET member and colonist of Xen was only one of a few survivors, this is my story...
