Bungie today announced the details of the Halo 3 beta for qualifying gamers; those that either got into the original registration period, those that won spots during the “Rule of Three” contest, or those that bought copies of Crackdown with the golden ticket inside. At midnight May 16th Pacific Time the beta goes live and will continue through the end of June 6th. Bungie is currently promising three maps for the beta program, Valhalla, High Ground, and Snowbound, available through the beta version of Bungie’s matchmaking service. Some of the new weapons and vehicles will be present in the beta, including the Spiker, Spartain Laser, and the Spike grenade. It sounds like some of the mysterious functionality of the “X” button will be revealed; from the video Bungie has released, it looks like the button will act as a “deployment” function for some of the new equipment in the game. Further details and information on the road leading to the beta can be found in Bungie’s new Vidoc, linked from their beta announcement.
