I was playing call of duty 4 today and I joined into a game. There was a "Hacker" and he had a program that leveled me up to 10 prestige and give me all the challenges ect. I was wondering if it was possible to get a rollback to what it was before the hacks. Because I don't know if I will get like banned or something for leveling up too fast or whatever. I have never used these forums before so my IGN is atomic_poptart if it doesn't say so already on here.
I don't believe you'll get in trouble for someone else leveling you up like that. Besides, that's probably happened to a lot of people already since there's so many hackers.
I don't believe you'll be able to get a rollback since the game is so old. However, you can try by contact Activision Support either on the phone or else through their online chat here: http://support.activision.com/Contact_Us
Hope this helped!
Keep on gaming!!!
