The beta for Command & Conquer 4: Tiberian Twilight goes live at noon Eastern time today through Gamespot (free GameSpot registration will be required to participate). EA's APOC tweets about the promised details on the public beta for the upcoming RTS sequel. Full details are on this page, where word is: "If Gamespot is temporarily out of keys, DO NOT WORRY, you will be placed on a short waitlist if necessary. You do not need to re-register. Once Gamespot releases more keys, you will be assigned a key in the order you joined the waitlist. Your own key is displayed on the page, as well as sent to you by email."
