- Odd One Out - A non-canon and satirical interpretation of the Halo universe featuring SPARTAN-1337.
- The movie gives Cortana's age as 7: "Chief, can you hear me? When I was born, 7 years ago, I already possesed the entire sum of recorded human knowlege." This places her time of Rampancy as approximately three years after Master Chief enters the cryo-chamber at the end of Halo 3.
- In Halo Orgins the infection forms are shown to be able to hover/fly however the infection forms in all the Halo games which they appear in they never fly only crawl and jump.
- In Halo Origins the scene remade from the 2nd to last mission of Halo 2 is shown that a Phantom crash lands on High Charity, thus releasing the Flood. This is different from the game, where it is shown as a Pelican's crash landing.
- One explanation for the above change is that since High Charity is such a massive ship, one single Pelican probably wouldn't be enough to infest the whole ship. There would have to be multiple ships (like the Phantom shown) for the Flood to successfully infest the whole ship.
- In Halo Origins; Thel Vadam (The Arbiter) Is shown to be at High Charity when the Flood invade alongside with the Prophet of Regret this is not possible due to the Arbiter being sent to Installation 05 by the Gravemind and the Prophet of Regret is shown in Halo 2 to have been absorbed by the Gravemind.
- The above inconsistencies may be due to Cortana's rampancy, which was caused by the Gravemind during the events of Halo 3. This causes the AI to flesh out memories that may not belong to her and are mostly inaccurate. This was also further supported by Frank O Connor.
- Another theory as to why these inconsistencies exist is to showcase key game characters (like the Prophet of Regret and the Arbiter)
- In Halo Origins the ring worlds are represented as being merely weapons, unlike in the games where they were depicted as "Ring Worlds" (e.g the rings have water and continents). Where in Origins it's just a big grey circular object with no water, continents or structures, so basically no chance of supporting life. Two reasons for this may be Cortana's rampancy or possibly the art director wanted to take a straight approach to show the true purpose of the ring worlds.
- In The Duel, the Hunters are shown to be massive, boasting a much more size than the Hunters of the Halo games; the Arbiter clamped onto a Hunter's back, and the size comparison is very different.
- However, Hunters are a collective body, so they actually could be the size that they are in The Duel if the Covenant had enough materials to do so. A reason why Hunters are never seen that large in the games is most likely due to the fact that it would be very cumbersome in battle, not to mention transportation.
