Basically i went on mw3 after many months and there was this guy in search who was killing people and being invisible at the same time, like literally invisible i was getting shot and there was no one near me and on the kill cam he was right in front of me.. Im guessing that there is some kind of infection or mod menu out and wanted to know how to get it? I am willing to pay but i need proof that its the infection/mod menu i want.

Thanks for any help
