I remember this being posted some years ago, it's fake. The laser blast at 3:15 is obviously fake and couldn't have come from the Covenant cruiser because not only was its glassing port facing [i]downwards[/i] (the laser comes from the side), but the player still shoots the ship and sees it crumble. The Autumn falling backwards is just a a rewind of the take-off layered over gameplay footage which you can tell because of the breathing animation of the Spartan and how you can see the sprint Armour Ability on his back (which you never see in actual cutscenes). Doesn't matter that I've posted this, some fool here will [i]still[/i] think it's real. :P
