This is the easiest way to do it. Some people have posted ways by going into team death match and then going really fast and going up but that one is way harder. Then there is another one were you have to join a game of a lvl 8 or lower which too is a much harder one. All you have to do is: 1. Put COD 5 in the disc tray 2. Let it load 3. Press start when needed 4. Go to multiplayer 5. Once on the Multiplayer screen highlight the Xbox Live selection and hit A really fast about 5 or 6 times then you should be in Boot Camp. 6. If your not in it then back out to the Multiplayer screen and do it again.
