Warhammer Online Preorder Codes

The Warhammer Online: Age of Reckoning preorder codes are special unlock codes included with a purchase of the Warhammer Online: Age of Reckoning Collector's Edition. The preorder codes will allow early access to the open beta of the game before its official release, the ability to play the game in the "Live Game Head Start Program" several days before launch, and will also unlock extra in-game content items. In order to take advantage of the preorder codes you must first purchase the game in-store or from an online retailer. For an in-store retailer purchase, you will be given a "Rave Card" containing your preorder codes. If you purchase the game online, the codes will be in your purchase confirmation email. Only 60,000 units of the Collectors Edition will be available in North American.
Open Beta Preorder Details

You must first create a Beta Center account here. After you have created an account, enter your preorder code in the Promotional Code field. You will then receive an email with instructions for how to download the game.
Live Game Head Start Details

In order to take advantage of this, you will need to create a player account at the EA Mythic Account Management website. Then input your Head Start code. After this you will be able to access the Live Game Head Start of Warhammer Online.
Unlocking Bonus Items

Similarly to the Live Game Heard Start process, create a player account at the EA Mythic Account Management website. Once you are in the game, your items can be obtained at an area called The Tome of Knowledge.
