One word: PunkBuster. If the mods are vigilant, it works. The clan I belong to does a good job of keeping cheaters off of our BFBC2 server and they didn't give us ANY tools to identify cheaters. At least the kill cams let you see that the person is cheating. : *snap*- headshot and they're always throat shots. I jumped into a game and died 5 times in a row from headshots the second I spawned in. I finally hit cloak but only got about 10 ft. before being brought down at range via headshot. There were 3 individuals in that server hacking and it totally ruined the game.
Fortunately, I was able to find one that didn't have a hacker right after that. This game is awesome when there aren't hackers. It's tough, but it's fun! The cool thing is you don't HAVE to use cloak all the time. You can experiment with so much stuff, it doesn't get boring.

Yes bump this. I know Crytek cares as do we.
