Halo 3 E3 2007 Trailer

The Halo 3 E3 2007 Trailer was a video relased by Bungie Studios for the E3 gaming convention, showcasing the first real glimpse at the Halo 3 campaign. It was also released on the night of July 10, 2007 via Bungie.net and the Xbox Live marketplace for free download.

Synopsis
The video begins with various images of Covenant CCS-class Battlecruisers and Assault Carriers wreaking havoc on the forces of Earth, as Phantom dropships unload Brute forces who brutalize human Marines. It is narrorated by a new, unfamiliar, raspy voice speaking for the Covenant (presumably a Prophet or Brute) mocking the humans attempts to defend the world. The movie cuts to the Master Chief, and continues on with nothing but orchestral pieces showing the Master Chief and the Arbiter battling through various Earth areas, against Phantoms and a new Scarab. It features Drones, Hunters, Grunts, and Elites engaged in combat, as well as a glimpse of the new HUD, which contains several new components.

Revelations
The video contains several new revelations for the game, both to canon and to campaign play. The biggest of which is that it seems that Master Chief and the Arbiter fight side by side throughout at least some of the game, defending Earth from the Brutes. Numerous shots show the Arbiter and the Master Chief fighting enemy Brutes and their Drone and Grunt forces. The video is the first to officially confirm that the Arbiter will be appearing in the game, and also features other members of the Elite race, confirming that the Elites and Marines now fight together against the Covenant.

The Video also features the apparent revelation that Dropships, including the Pelicans and Phantoms, will be destructible, and able to be shot down in the campaign. It also features all new Scarab walkers, much more heavily armed and armored than those that have appeared before. The Master Chief and Arbiter will work together to bring at least one of these down.

343 Guilty Spark and Cortana make their first appearances, showing that they, along with the Master Chief and Arbiter, will work together at some point. Furthermore, it is shown that other than the Brutes, no other Covenant warriors have undergone any significant changes from Halo 2. (Hunters, Grunts, and Elites look almost identical to their former appearances, while Drones are given significant technical improvements). Human Marines have undergone major graphical improvements, and Commander Miranda Keyes has undergone an overhaul, with a more detailed uniform and hair which is noticably browner than before.
