Introduction
We?re pleased to be able to invite you to the Crysis Wars Holiday Trial period taking place from Saturday, December 19th to Tuesday, December 29! All you need to do is be a registered member of MyCrysis in order to receive all the information you'll need to take part, there's still plenty of time to sign up so make sure you don't miss out!
If you already own and play Crysis Wars, this period will be a fantastic opportunity for you to meet new players and make new friends.
If you don't own Crysis Wars, this is a unique occasion for you to download the FULL game with its 3 game modes and 21 maps. As soon as your download is over, you will be able to play on LAN with your friends for free. Once the trial period commences, you will receive a unique CDKey so that you can play online for free until December 29th!

How does it Work?
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.
On Saturday December 19th, 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 trial period. This demo CDKey will only be valid for your MyCrysis account, and will allow you to play online for the whole ten days. By the end of the trial, 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.
