{{Status|RealWorld}}

The video begins with various images of [[Kez'katu-pattern Phantom|Phantom]] dropships unloading [[Jiralhanae|Brute]] forces who brutalize human [[UNSC Marine Corps|Marines]], as well as [[Covenant Empire|Covenant]] {{Pattern|Ket|battlecruiser}}s and [[CAS-class assault carrier|assault carriers]] [[glassing]] [[Earth]]. It is narrated by the [[Prophet of Truth]] speaking for the Covenant, mocking the humans' attempts to defend the world. The movie cuts to the [[John-117|Master Chief]], and continues on with nothing but a dramatic new rendition of the Halo theme (on the ''Halo 3'' Original Soundtrack, it is titled "One Final Effort") and showing the Master Chief and the [[Thel 'Vadam|Arbiter]] battling through various Earth areas, against Phantoms and a new [[Deutoros-pattern Scarab|Scarab]]. It features [[Yanme'e]], [[Jiralhanae]], [[Mgalekgolo]], [[Unggoy]] and [[Sangheili]]. as well as a brief glimpse at a [[Kig-yar]] engaged in combat, as well as a glimpse of the new HUD system, which contains several new components.

The video also features the apparent revelation that [[Kez'katu-pattern Phantom|Phantom]]s will be destructible, and able to be shot down in the campaign. It also features all new [[Deutoros-pattern Scarab|Scarab]] walkers, much more heavily armed and armored than those that have appeared before.
