Ok, for those of you who have not finished the campaign, no spoilers here. If you have finished the campaign, good for you, however I bet you hated the ending, right? Either way, there is some extra footage available on Legendary mode! After you finish the Pillar of Autumn menu (before the start of Survival) when the UNSC officers are talking in the cruiser, you can hit the right bumper, which will pan the camera right to show Master Chief and Keyes having their own conversation in the next room! Enjoy the extra footage, assuming you can beat it on Legendary...
