You have to be a registered user at MyCrysis.com before Thursday, Oct 9 2008 for entering the weekend online trial.
You will be able to download the complete Crysis Wars game, and install it on your computer for free. From then on, you will be able to play on LAN with your friends, without any time limitation. This is the best opportunity to check the gameplay, adjust the settings to your fitting (from best performance to best visuals), and train with your friends on LAN, in preparation for the online weekend.
You will not be able to connect online during this time.
This Friday October 10th, starting at 6pm CET, a new mail will be sent to you with the link to a MyCrysis page where you will be able to retrieve your unique demo CDKey for the online weekend. This demo CDKey will only be valid for your MyCrysis account, and will allow you to play online for the whole weekend. By the end of the weekend, your demo CDKey will be deactivated and you will have to purchase the game to keep playing online.
The whole Crysis Wars team hopes that you will enjoy this experience, and we are at your disposal at MyCrysis.com to answer your questions and react to your feedback.
