Splinter Cell Easter Egg - Ufo Sightings Room in the C.I.A. Building.

In the CIA headquarters mission, at one point, you will have to trail and kidnap a guy. follow him until a t-shape in the corridor. to the right should be a pair of glass doors where he goes, but on the left is another room, wich most people usually miss when trying to keep up with the guy.

next to the door is a sign that reads "UFO sightings". inside is a computer and a keypadded door. use the computer to get a data stick. it has an encrypted message on it, and a number repeated 3 times. enter that number on the keypad to gain entrance to the room with a load of folders, filled with the truth about UFOs, just out of reach behind a set of steel bars. *sigh*

As compensation, there are some sticky shockers and cameras in there though.
