ONI Archive

ONI Archive is a video content series tied to Halo: The Master Chief Collection's release on PC. The series consists of a number of trailers designed to recap the the general outline of each game in the collection's story and prepare new or returning players for jumping in to each game's campaign. Each video is framed with an in-universe narrative, with the videos presented as a series produced by Section Two of the Office of Naval Intelligence, aimed at educating civilians on the final months of the Human-Covenant War.

Meta-narrative

"So why should you care about some random ONI Section III comms officer and their co-workers? Well, I suppose that is indeed the question isn’t it?"

— Jeff Easterling on the ongoing narrative.

In keeping with the in-universe framing of the video series, the videos contain their own narrative audio drama. At the end of each video, starting with Conflict Evolved, the final part of the trailer is cut off with a "Transmission Interrupted" notice, and a short audio snippet is heard. The audio drama centres around Director Schaefer and a unnamed Comms Officer working within ONI, and features numerous nods to other pieces of fiction with the mention of characters like Michael Sullivan. In Allied Forces and Helljumpers, the Comms Officer comes across upon some new - presently undisclosed - information, which is soon followed up by Codename: FIXER. This meta-narrative presumably ties into the upcoming Halo Infinite.
