generally unrelated to the main storyline and not considered canon. In these videos, the members of both teams are actors who claim to be from Red vs. Blue. Although the visual background of Red vs. Blue was primarily taken from the Halo series, Rooster Teeth consciously limits connections to the Halo fictional universe. A special video made for E3 2003 portrays Master Chief, [[Halo (series)|Halo'''s protagonist]], as a larger-than-life member of the army, and the Red vs. Blue trailer and first episode establish that the series is set between the events of the first two games.

Throughout The Chorus Trilogy arc, the UNSC's role in the series was greatly expanded in explaining the abandonment of the planet Chorus. This is primarily due to the arc's antagonist, Malcolm Hargrove, working for both the UNSC and his own company, Charon Industries, with the intent to wipe out all life on Chorus with the help of
