The Command & Conquer Blog has word that the prequel mission is now available to all Command & Conquer 4: Tiberian Twilight owners, a preorder mission called Night Moves ("I woke last night to the sound of thunder..."). Word is: "Just check your campaign screen for the “PRE-ORDER BONUS – Night Moves” mission and be part of Gideon’s master plan to lay a trap for the false prophet Kane." They also offer help for those who can't access this: "If you registered your C&C4 Tiberian Twilight account after March 2011, you will not be able to play the bonus mission right away. Just post in the prepared help thread on our official forum, and we will manually grant you access to the bonus mission!" Thanks Ant via Planet Command & Conquer.
