Halo 3

    The first trailer to display the Master Chief in Xbox 360 splendor..

Description: The trailer features our main man Master Chief and of course the appearance from Cortana. However all is not right, it would seem the Chief has found himself in a strong hold of one of the various foes in the game. Not just that but Cortanas code must be all buggy because the things she is saying don't make very much sense.
