Ruh roh!
The blurb on the official blog reads: "We do take cheating very seriously here at Crytek. We are currently taking steps to permanently remove exploits from Crysis 2 and to penalize those individuals that choose to utilize them. We thank you for your patience and want to ensure you that we will continue to work hard to keep the integrity of Crysis 2 intact and cheat-free."
We have no idea what the cheats or exploits are, although I'm sure some of you will tell us in the comments, but the moral of the story is, "Play nicely in Crysis 2 or Crytek will spank your ass!" SPANK YOUR ASS, I SAID!
