A new live action trailer for Halo: Reach has been released. Entitled "Deliver Hope," it features Noble Team battling against the Covenant. Set before the game, this video shows us how Kat looses her arm and how the original Noble Six (whom you replace in the game) is killed.
Very, very cool. According to Bungie's Weekly Update, the extended version will be released on September 6th, which I'm quite looking forward to.
