If you experience any of these symptoms, or have had a history of issues with Crysis 3, stop playing immediately. If depression occurs or your have unusual changes in behavior or thoughts of suicide please play something else. Rage quitting may be a sign of a unstable personality or could just be a normal reaction to the worlds worst patch.
