Production notes

 * In part 4, the statement made by Guilty Spark to the science teams attempting to withdraw data from him is the basis of the novel Halo: Primordium.
 * Similar to the Data Drop, which led up to the release of Halo: Glasslands, the Eleventh Hour reports were 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 October 10, 2012 edition, the text was hidden with invisible text.
 * The third, fourth, and fifth reports in document form were found during the Section 3 Alternate Reality Game, hidden within PNG files.
