Halo: The Journey

"Your journey begins."

- Halo Xbox One announcement trailer

Halo: The Journey, or simply The Journey, is a multimedia series that comprises games, novels, comic book issues, live action and animated series, and promotional materials. Originally announced in 2013 with the Halo Xbox One E3 teaser trailer, it officially started in 2014 with the release of Halo: The Master Chief Collection, and continued up to the release of Halo 5: Guardians in 2015.

The Journey refers to the Master Chief's personal journey after the events of Halo 4. To an extent, it also applies to the origin stories of the other major characters featured in Halo 5: Guardians.

Halo: Escalation
Halo: Escalation was a comic book series that started in late 2013. Its main purpose was to bridge the gap between Halo 4's Spartan Ops and Halo 5: Guardians, by continuing the story of the 's crew and that of the alliance between Jul 'Mdama and Dr Halsey. However there were some specific story arcs that were explicitly tied to The Journey. "The Next 72 Hours" was a three-part arc that narrated the reunion between John-117 and Blue Team after the events of Halo 4, and their conflict against the Didact who had survived his first defeat. "The Glass Horizon" was a two-part arc that told the origin story of Holly Tanaka, a character set to appear in Halo 5: Guardians as part of Fireteam Osiris. "The Absolute Record" was a six-part arc that continued Tanaka's story after her becoming a Spartan-IV, connecting it more closely with the fate of Infinity, 'Mdama and Halsey.

Halo: The Master Chief Collection
Halo: The Master Chief Collection was the journey's first major step, released on November 11, 2014 as the first core Halo game on Xbox One (Halo: Spartan Assault being the first Halo released on Xbox One a year before).

It comprised Halo: Combat Evolved Anniversary, Halo 2: Anniversary, Halo 3, and Halo 4, and also included exclusive access to Halo: Nightfall and the Halo 5: Guardians Multiplayer Beta.
