Have you come across a Crysis 2 multiplayer match with a cheater or a hacker?Hear what Crytek has to say...

We know that some people have been playing with an unfair advantage in the Crysis 2 demo. Rest assured that although the demo does not have these features installed, our team has been working for some time on various anti-cheat measures that have been introduced for the retail release of Crysis 2. We would like to make sure everyone is aware of how important this issue is to us, and that we will continue to strive for a cheat-free community with Crysis 2. "

So, did you progress?
According to player reports and youtube videos, there are a lot of hackers.

LOLOLOLOLOLOLOL.


It seems there have been a few holes in the "Anti-Cheat System".

they needa get on this asap. Especially for all those people with ridiculous KDR. Must be nice to have a 138457092830958203.5 KRD ratio. awesome.

The KDR was already **** up in the demo^^. Easy to spot cheaters by the way....

Too bad these console morons didn't use PB or VAC

Gamespy? **** GAMESPY? LOLOOLOLOLOLOLOLOLOLOLOL

In my experience, PB is a horrible anti-cheat system. lol FC2

PB's problem is it hates non cheaters too lol!

I think it's in the interest of every body...I won't buy any dlc if the game is full of cheaters.

We’ve been working hard to resolve as many of the post-launch issues as possible including some improvements to our game security. These updates will be made available via automatic-download later this week.

Awesome, Thanks for the notice Cry-Tom

Thank you.
Despite some people says, Crysis 2 is a very good game and i know this is hard for you to work under pressure.
Has long has you know that some people support Crytek...
Like Jean-Claude said, we are "AWARE" that no game is perfect in the first week of its launch.

Nice but I don't understand why can't someone simply check the leaderboards and instantly ban all those people withy 300.000 kills and 200 deaths, there's no proof needed or anything, just kick them.
