Hey, theres one station glitch alot of people know. the one where you can get in the box. Well go to the ladder closer to the spot Mi6 starts off when you get to the top you'll see a blue box go over to it the side and start walkig in it and keep crouching up and down. if you do it right you will fall through the floor. If you do it wrong then you will go through the little wall thing out in the open
