The following is a list of lore discrepancies in the Road to Halo video series.

Pt. 1 - The History of War

Footage from the games is used to capture the general aesthetic of a time period, rather than adhering to canonical placement. Example: the deglassing operation on Meridian takes place after the Covenant War, but is used as a stand-in for early industrial colonies prior to Reach.

Epsilon Indi's location on the star map is addressed in The Location of Harvest.

The six proposed space tether sites shown were: Quito, Havanah, Lagos, Mombasa, Mumbai, and Singapore. The actual locations were revelead in the Halo Encyclopedia (2022 edition): Quito, Havanah, Malabo, New Mombasa, Colombo, Borneo, Aranuka.^[1]
There remains some debate about whether humanity settled worlds outside the Sol system before Reach, which was colonized by the Odyssey in 2362 and marked the beginning of the Domus Diaspora. The original Xbox.com timeline states that colony ships were "unveiled" in 2310, and the Halo Encyclopedia (2022 edition) states extrasolar colonies Juneou and Titus had colonization dates of 2330 and 2355 respectively. An explanation as to why humanity unveiled their ships in 2310 and then waited 52 years to start the colonization process has yet to be given, beyond "decades of planning".^[2] Most sources state that the Odyssey was the very first colony ship and Reach the very first colony. Until these facts are resolved by official sources, in the Extrasolar Era section of the video I have made some "headcanon" attempts to resolve this discrepancy, proposing that there were extrasolar colonies before Reach, but that they were industrial/science outposts rather than true civilian colonies. This preserves the unique storytelling potential of the 52-year interval.

The CMA logo does not (as yet) have an official icon. The symbol used in this video was created by Stephen Loftus using assets from Halo 4. More here: Road to Halo | Behind the Scenes

This video states that the Epsilon Eridani system was colonized in the order: Reach, Tribute, Circumstance, Beta Gabriel.^[3] The order given by the Halo Encyclopedia (2022 edition) was: Reach, Beta Gabriel, then Tribute and Circumstance the same year.^[4]

Although the line between Inner and Outer Colonies has been described as a geometric sphere,^[5] the map in this video allowed the animator creative freedom to portray an alternate boundary.

Pt. 2 - Spartan-II

The SPARTAN-II program officially began in July, not August, but this was altered in the narration to match the on-screen visuals.

In the source material, John flips the coin only once, as that's all that's needed to determine his 50/50 selection chance. This was changed in the animated series to five successful flips. It was kept in for this project both for ease of editing and "headcanon" reasons. Theoretically, all the Spartan candidates had to flip a coin (either literally or virtually) to determine their spot as well, so having him succeed five times in a row keeps his instance unique.

The illustration of a flash clone in Halsey's journal is in fact an illustration of Kelly-087 after her abduction.

In the audio clips from i love bees, Kamal Zaman's sister Yasmine was actually abducted for a planned second class of SPARTAN-IIs. The clips are used due to their similarity with the experiences had by Class I Spartan-II abductees. The full audio drama can be listened to here.

Some events which occurred during SPARTAN-II training were not given concrete dates. Reasonable guesses were made with the assistance of Stephen Loftus.

Fhajad's name was mispronounced so that it would match the pronunciation of the audiobook narrator.

Some minor details of the Spartans' CTF exercise against Tango Company (such as specific equipment, personnel distribution, etc) are not accurate to the source book. Production realities forced this sequence to be assembled at the last minute, but broad tactics and outcomes are still accurate, with internal consistency in the context of the video.

Halo: Contact Harvest claims that the National Holiday luxury liner bombing in 2524 was "the first time the Insurrectionists had hit a non-terrestrial target". This contradicts depictions of Robert Watts' earlier naval campaign against Eridanus II from Halo: Fall of Reach.

The augmentations are depicted in Halo: The Fall of Reach - The Animated Series as resulting in the deaths of 27 children, which contradicts the source novel where 30 children are killed. This was left in for the sake of including as many visual depictions of events as possible.

In progress...
