I just saw this. I don't really know why they did a live action trailer, must've cost a lot of money but meh... Also, this might be better in Halo: ODST discussion. EDIT: there is already a thread here
Egh their money to spend in a dying economy so whatever lol. Pretty awesome trailer though. Im not exactly sure if the old guy in the end is the young guy in the beginning but I thought they did a good job. Just a little more insentive for Microsoft to do the actual Halo movie. **** looks impressive.
