About

It seems the G-Man and his government forces cannot keep Xen under their control. We all know how the government responds to something it can't be in charge of....blow it up ! Here's where you come in. The aliens, recognizing your impressive abilities, turn to you for help. If anyone can beat the G-Man at his own game it's you, and the aliens know this to be true. So begins your mission of mercy to save the alien world...... Hiding in the back of a big-rig, you slip into the compound. The science team has prepared the way for you, and Barney will help you when necessary. Not all areas are under heavy guard, but watch your back! Prepare to take on the G-Man's best troops.
