Seems like some people are having a hard time registering so I thought I'd post more explicit instruction:
Go to the Warzone webpage (www.warzoneri.com
) and follow the link on the top (the one that says “click here for more info and to pre-register”).
On the bottom of the page it brings you to is a PayPal “Buy Now” button.
Be sure to enter your name in the “Name of Registered Player” box
