Secret Rebel Agent Kyle Katarn will do anything to avenge his father's untimely death at the hands of the Empire. When Kyle is threatened by 8t88 in a Nar Shaddaa bar, he tracks down the droid and secures a mysterious disk that could put him on the path to learning why his father was killed. Kyle soon finds that the disk contains information about a map to the Valley of the Jedi, a place his father had stumbled upon and kept secret. Now it's a race between Kyle and the Empire to see who can get to the map—and the Valley—first.
