Get ready to set your browser to auto refresh because Bungie is opening up Halo 3 for beta testing starting today. They haven’t said when the Halo 3 homepage will start accepting applications, but it is probably around the same time the Halo 3 ad is going to be shown during Monday Night Football. Our guess is sometime around 5:50 and 6:20 p.m. PST you will be able to register for the Spring 2007 beta. Good luck!
Update: Applications are being accepted NOW (4PM PST). Go for it!
