MyCrysis has news that the Crysis Wars summer trial period has been extended until Tuesday, September 8, offering further free access to Crytek's Crysis multiplayer game. Apparently there were issues for some users that prevented them from being able to properly generate a CD key, but these have been resolved now. Extending the trial allows those just now able to get a key to enjoy a full week's worth of play, while providing a bonus to those who have already been playing.
