According to the NFO on NFOrce it has NO PROTECTION!
I don't have the game, but I downloaded and installed the 1.1 patch (It doesn't check the game is installed first

) and found nothing with PiD only a possible CD/DVD check in core.dll?
What happens when you run the game when it's patched to 1.1?
Download PiD from here:
http://pid.gamecopyworld.com/ and scan your game when it's patched to 1.1 and you'll know if it's copy protected!
