Halo Encyclopedia (2022 edition)

The Halo Encyclopedia is a reference book originally set to be published on March 29, 2022 by Dark Horse in conjunction with 343 Industries, but later delayed to April 12, 2022. The book is a successor to the previous Halo Encyclopedia released in 2009, and features numerous custom-made pieces of artwork by both 343 in-house artists and several images and designs created by the fan mod Sins of the Prophets and Halo: A Fistful of Arrows creator Levi Hoffmeier.

The book includes elements from across two decades of Halo history, including content from Halo Infinite.

A deluxe edition variant was additionally released, containing an exclusive lithograph, a unique cover and slipcase inspired by the Forerunner Cylix.

Content
The Halo Encyclopedia begins with a chronology of the events in the Halo universe. The book is divided into five sections: Humanity, Covenant, Forerunners, Flood, and Banished.

The book's meta-narrative is framed as an communications log between Adjutant Revendicate - the sub-monitor of Installation 07 created from the mind of the Auditor - and Invariant Bias, Monitor of the Absolute Record. The brief exchange is present in the books opening and closing pages, and details Revendicate's wishes to enter information into the Absolute Record in the wake of The Harbinger's defeat as depicted in Halo Infinite. The Halo Encyclopedia's text is framed as the repository of information gathered by Revendicate, giving the book an in-universe grounding in a similar manner to the Curator meta-narrative framing 2016's Halo Mythos: A Guide to the Story of Halo.

Trivia

 * The and the  were due to be featured in the Halo Encyclopedia but were cut due to space constraints.

Mistakes

 * The CQS48 Bulldog is stated as having an 8-round magazine. The correct number of rounds should be 7.
 * The image captions for the Sangheili Honor Guardsman and the Sangheili Councilor are swapped.
 * The M247H machine gun is given two conflicting infoboxes on pages 174-175, with the conflicting designations M247 heavy machine gun and M247H heavy machine gun. The two images seem to use the Halo Infinite model and the Halo: Reach model respectively, and provide conflicting length measurements of 64.6 in and 64.5 in, respectively. It is unclear whether this is intended to explicitly separate the two models into similar, albeit different weapons, or a mistake on the part of the authors.
 * On pages 136 and 180, the Halo 5: Guardians chaingun is referred to as the M49 Vulcan, while on page 170 it is named as the M250 heavy machine gun.
 * On page 136, the Halo 5: Guardians gauss cannon is erroneously referred to as the M69, while its dedicated infobox on page 181 refers to it as the M70 Gauss cannon.
 * On page 153, the image captions for the Series 8 jetpack and the Series 12 jetpack are swapped.
 * The designation provided for the 's Magnetic Accelerator Cannon is given as the 21X5V9 MAC, contradicting the 56A2D4 established in Halo: Warfleet.
 * The weapons loadout listed for the is retained as that established for  in Halo 4; in Halo 4, the ship was incorrectly depicted as much bigger than any UNSC frigate or cruiser, and had a massive armaments complement to match. As such, the armaments loadout provided (particularly the three Hyperion missiles) would not be able to fit inside the canon Charon.
 * The Halo 4-given armaments for the Charon include 3 Hyperion missiles, and 50 Archer missile pods; the canon model (as depicted in Halo 3 wouldn't be able to fit any Hyperions inside, and only has 5 Archer pods. The number of Magnetic Accelerator Cannons and Rampart point-defence turrets remains accurate to the canon model.
 * The size statistics for the Klavrig Workshop Skitterer, as listed on page 457, are enormous and much bigger than the Skitterer's in-game model or the concept art scale reference, and even bigger than other vehicles in Halo Wars 2 such as the Locust. It is unclear whether this is an intentional upscaling, or an error in numbers.
 * On page 458, Okro 'Vagaduun's birth world is listed as Feldokra while Halo Infinite instead establishes that he was born on Sanghelios' blood-moon, Suban.
 * On page 479, the is stated to be manufactured by Lodham Armory. Given Lodam Armory is a known manufacturer of the Needler, and this is the first time a “Lodham Armory” is mentioned in the series, it is most likely a typo.
