I used it on private sp and it worked just fine but two missions require a second person so I went on private online match with a friend! The game restarts very often before complete the mission! In my friend's screen he views me as dead before it restarts but their bullets "won't touch" me cuz of the aimbot and the life hack (in my screen). I never died on my screen.. Both of us were hosts but we couldn't fix it and I didn't get banned yet after I used it "online" ;D It's a great hack btw and a very helpful tool on SP!
