EA Mythic has clarified an issue involving the expiration date listed for pre-order codes from collector's editions which were pre-ordered through Amazon.com. The codes were originally listed with an expiry date of June 10th, but EA Mythic says that the CE pre-order codes don't have an expiration date.
It has come to our attention that those of you who have pre-ordered from Amazon.com were given an expiration date of June 10, 2008 for entering your codes.
Please note: CE Pre-Order codes do not expire.
The Open Beta code may be redeemed at anytime leading up to and during the Open Beta phase. Our account services will provide you with the means to enter your Head Start and Item codes prior to the opening of the Head Start program, at this time we ask you continue to keep those codes in a safe place for later use.
The Pre-Order FAQ will be updated to reflect this as well.
