Splinter Cell: Chaos Theory Easter Egg - Disco Hall

first, go to the level "Factory" go to the main hall with the large bin. by the domed tunnel, you should see a ladder. climb up and you should be on a catwalk with a pole that seems out of reach.jump on the rail that is on the same side as the pole and walk along it, face the pole and jump onto it(you should make it).climb all the way to the top and slide back down. about halfway down, you will automatically fall off.walk in the hall until you see a door with flashing lights behind it. open it and the room beyond has disco style light, Chaff "confetti", and in some spots a disco beat.if you do it more that once, the chaff and music will dissapear. It's significance? well every worker needs to party!
