What you need to know about DRM & copy protection, not so bad after all ?
The DRM system implemented for the Crysis Warhead changes copy protection from being key-disc based, which requires authentication every time you play the game by requiring a disc in the drive (this was the system we used in the original Crysis), to a one-time online authentication. This system allows you to play your game without requiring the game disc in the drive on any of five different machines.
Please note: this DRM solution is for the Crysis Warhead disc only. Because of the online nature of Crysis Wars, and because we want to encourage easy-to-start LAN play, you are only required an authentication upon installation. If you want to play online on our servers, you will authenticate via Gamespy as you normally would.
Key Points
- This system allows you to authenticate your game on five computers with the purchase of one disc – you can install your copy on each machine as many times as you want. If you go over five machines, EA Customer Service is on hand to supply any additional authorizations that are warranted.
- This DRM solution is safe. EA and Crytek would never allow anything that included spyware, viruses or malware to be installed on anyone’s computers.
- We know there is concern about what will happen if the authentication servers turn off or questions about what will happen in five years if you want to play the game again (and we hope you do). If that were to ever happen, Crytek and EA would deploy a patch that would remove the authentication requirement completely.
