Report hacker

To report a hacker, Match replays needs to be saved in CrossFire by clicking the "Save" button on the results screen after the match is over or whenever you leave a match. Once the file is saved, it will appear in your "C:\Users\username\Documents\Cross Fire\Replay" folder (default). You can then fill out a hack submission form and upload the replay file through the support site.

Here is a guide which will help you fill out the form: http://forum.z8games.com/showthread.php?213755-Opening-a-support-ticket-on***********com&p=3033142#post3033142

I hope that helps!
