The Command & Conquer Website has details on how to access the Command & Conquer 4: Tiberian Twilight beta test if you are a Red Alert 3 Premier Edition owner who registered their "Future Beta Access" code. There are other ways to gain entrée into the beta test of the real-time strategy sequel for those who have preordered the game, are a GameSpot subscriber, or have won one of the C&C4 beta contests, and these are all outlined on Command and Conquer DEN. Thanks Ant.
