Your .pak files have already been cracked and people are already modding the game. You should have known this would happen with such a game and the kind of PC community you have following it. Might as well decrypt the files officially and release modding tools officially so this doesn't turn into a huge mess. Face it, people WILL do things to Crysis 2. It is what the game has been in the past and we will make it that game again ourselves or you can do something to help us.

How have they cracked them?

Sweet this website is **** - Double Post

I have seen a ballistics mod somewhere and in a similar thread there was a download to Crysis 2 PAK unlocker.
