I hope there's no hacks or glitches in the game AT ALL. I had a great time on MW2 (PS3) because there were no hacks at all. I ranked up to 10th prestige legit, with a lil cage match boosting here and there. I was about level 30 10th Prestige when I saw my friend playing FFA on Rust. I was like, cool quickscopes, so I joined. It was the first time I ever joined a modded lobby, and I got kicked out. When I returned to the main menu I was level 70. He upranked me to 10th prestige Level 70 after going through the previous 730ish levels to get where I was before I joined that match, which pretty much ruined my legit 20 days played.
What I'm trying to prove is that hackers ruin the game for legit players who just wanna have fun and rank-up and play the game how it's supposed to be played. If you must hack, please do so outside of public matches and don't be dicks about it too (stat changers, challenge unlock/resets, etc.).
Hacks and glitches can be fun, don't get me wrong I did elevators and modded lobbies like everyone else, it's just the rank stuff that ruins it and makes every 10th prestige player, whether legit or hacked, be called 10th prestige hacking faggots.
