Halo 2 theatrical trailer
From Halopedia, the Halo wiki
In late summer of 2004 there was a cinematic trail of Halo 2 that was shown in movie theaters in the United States. It is mainly a montage of shots from the game. Most of the shots are for the Halo 2 E3 demo.
Summery
The trailer starts out with the words: "The most lethal force in the universe". The screen flashes to a shot of several Elites. Then it continues: "Has destroyed everything in its path". It flashes a shot of a Pelican landing and a shot of a Ghost taking fire from a Phantom. It goes on to say: "On November 9th, What's in its path... is us." and the screen fades to a shot of the Earth. That shot vanishes. A Pelican roars over head. A ghost is chased by a Phantom. It shows the Master Chief standing on a roadway watching Orbital Insertion Pods descend on New Mombassa. The writing reappears and says: "We're not ready" and shows the Master Chief cocking a Battle Rifle, a Warthog engaging Shadows, and some shots of multiplayer. The writing then says: "He is". The camera changes and shows some wreckage. It pans up to show The Chief standing atop a chunk of debris, wielding a pair of SMGs. Several Phantoms fly over him. The Master Chief looks into the camera and jumps. The screen flashes to the Halo 2 logo with an orange clouded background. A voice then says: "Rated M for mature"
