Gravesite

Gravesite is the last video featured in the Halo 3 Believe advertising campaign. With a release date of October 1, 2007 the video is set to follow the rest of the series including Hunted, Museum, and Enemy Weapon.

As of October 4th, 2007 it is still inaccessible for unknown reasons. It may have been replaced with the "Shooting A Hero" video available at the Jack Courage article on this site
