Erm well, you watch a clip, you get level 55..

I mean, how did the clip work?

It was just a theater clip of Nuketown that was 6 seconds long, you would watch the entire clip, end game and instant level 55! It didn't give you score or anything though so it's pretty obvious you glitched your level plus you can't play online unless you prestiged, so you could only go to 9th prestige at the highest, then you'd have to play through 10th legit. Like I went to 2nd prestige and am doing 3rd legit so basically go to the prestige BEFORE the one you want then prestige and play legit. I think the video is gone now though. not too sure?

Where can you get the video??

how i can find the video?????

I know what you mean.. because i did it and got to 9th, and reset my stats because i bought too many custom classes, but i'm asking how did the video work? how did it get you to 55 by watching it?!-.-

The video is gone now guys, oh right.. sorry, did not really understand your question!:L Well, I'm not too sure myself, think it was just a hacked video!
