Eleventh Hour reports

The Eleventh Hour reports is a series of reports created by Codename: SURGEON. The reports are sent to Codename: COALMINER detailing the status quo of the post-war galaxy. The introduction ponders how humanity will adjust to the new galactic paradigm, while the first report discusses the disposition of some of the Covenant's former client races. The second report detailing the origins of the SPARTAN-IV Program and the Spartan branch. The third report detailing a expedition to Installation 00's debris. The fourth report detailing humanity's progress in locating and investigating the remaining Halo installations.

Behind the scenes
Similar to the Data Drop, which led up to the release of Halo: Glasslands, this analysis was used to promote Halo 4 and to provide more insight into the contemporary state of the galaxy. Like the Data Drop, one installment was featured in each weekly Halo Bulletin, beginning with the 10.10.12 edition. Unlike the Data Drop, however, SURGEON's report is written with invisible text; to see it, the reader must drag a selection box across the article. The fifth report was found during the Section 3 Alternate Reality Game, hidden within a PNG file.
