Call of duty Ghost has hacked Lobbys

Recently, I've been in a hacked lobby on xbox 360, which ranked me up 60 times to reach the second level. As you know, it's a bit harder to level up. At first, I thought this game wasn't going to be hackable, but that's a funny statement because almost anything is hackable. So, what's your thoughts about this? And if you're wondering how i got this game early, it's because i have a friend whose dad works at a gaming company and he gets games early and he gives it to his son, which sells us the game 3-5 days earlier than the game's release date. Do you think when xbox one or the xbox 1 will have any hacked games?

Here's a video of a hacked lobby
