Microsoft has finally revealed the surprise with which different tweet had mentioned yesterday: there was no new beta , but this is how many predicted a new video. For the accuracy is the opening CG movie campaign, where Jameson Locke and Osiris Fireteam members prepare for the first mission of the game, where they will have to retrieve Dr. Halsey in enemy territory. The next sequence shows us the incredible power of four Spartan, in a succession of extremely spectacular actions. Good vision!
