What exactly where these hackers doing because i haven't come across any - to my knowledge-

I haven't either, but at least Crytek is looking out for the community in that department.

The less cheaters, the better.

Just got in 2 differents game with hackers.

Really HIGH speed.
Enormous damage of bullets.
Auto-aim
...

maybe more! but it was enough for me! I left.. and now begining to think that i shouldn't have buy this game!

( Max level too 50 ) both of em. So maybe take a look on our high level! some of em may not have reached it legit =)

And for kill-cam was kinda easy to see it was auto-aim his gun was just shooting everywhere and killing people ! he won the game in less than 1 min.

PlaneswalkerX - one of em!
