Some lucky gamers have been receiving confirmation emails indicating that they've been entered in the "Halo 3" online beta. Others, like myself, have received an email saying that if "you have been selected to participate, you will receive an email notification within the next two days". Start checking your inboxes! If you don't get in, the easiest way to participate would be to get a copy of "Crackdown" when it hits store shelves on Feb. 20.
