Although it does, it technically doesn't. Canon created by the developers overrules all else, it still doesn't justify what Bungie did nor does it explain why. I believe it was a big "-blam!- you" to everyone that knew the lore and unfortunately for Reach, it was one of two guinea pigs in creating Destiny.

It didn't. Game canon over rules book.

Random question here. Does anybody know what happened to Jun? He left with Halsey but I don't remember anything after that?

Most of the points Hunter Killer made were the points of contention, but they have since been amended by 343i.

Reach broke canon in several ways. -Dr.Halsey knowing about the existence of Spartan-III soldiers before the events of Ghosts Of Onyx. I think the Halsey journal tried to cover for this one by saying she didn't know they were actual spartans, but her calling them spartans several times during the campaign contradicts this. -The Covenant's attack on Reach taking place over a period of weeks rather than in a single day. Isolated surface units and small scouting corvettes would be easy for ONI to hide and understandable in the lore, but the 27km long CS0-Class Supercarrier "Long Night Of Solace" being in orbit without the majority of UNSC forces aware of its existence, is just not reasonable. Neither is an additional fleet of covenant ships slipping in system on August 14th that also apparently go undetected by the majority of the UNSC Navy. -As stated in Halo: The Flood, the Pillar Of Autumn was not designed to go anywhere near an atmosphere, and was not capable of operating or landing within one. Bungie attempted to right this with the thruster jets applied to the shIp's underside as visible in the game's second to last level, but even if that story works it still leaves a big unanswerable hole in the POA's story. The ship had been fighting Covenant forces in orbit since the large fleet (314 ships if memory serves correct) slipped in system, and almost everything the ship did in that time is documented in the book. It had no time in the middle of this battle to stop fighting, land in atmosphere and then return to orbit. The master chief easter egg in the final level complicates this further, as apparently when the ship landed chief was already in cryo sleep, despite not entering it until they had slipped out of the system as detailed in the book. -The entire final plot of Halo: Reach is a retcon. According to the game, the reason Cortana was able to decipher the location of halo was because a piece of her (The piece delivered by Noble Team to Captain Keyes) contained the coordinates for the ring, and had been found in the ruins of the forerunner artifact beneath Reach. The book however, tells a very different story. According to the book, Cortana discovered the coordinates to Installation 04 through study of the artifact recovered by Blue Team in the Battle Of Sigma Octanus IV. She inputted the coordinates into the ship's nav in favor of a blind jump, and as far as the book told no one on the bridge including Captain Keyes knew it wasn't a blind jump Cortana was making. There are others such as Spartan-III commandos having access to MK.V Mjolnir before the Spartan-IIs, and the massive battle in and glassing of a major city (New Alexandria) apparently going unnoticed by the majority of the planet and military for days, but I think these have been explained in the lore post-bungie by way of 343i's data drops and other references.

I would have preferd a game that followed the fall of reach book, maybe not from master Chiefs perspective but another Spartan in his team.

#inb4lemon Oh wait.... Pretty much what Hunter Killer said but to add to that 343i did revise the book, The fall of Reach. I am currently reading the revised version. I was put off by some users here as I really liked the game, I didn't want to tarnish my memories of the game. [spoiler]Yes I loved Reach, I like all the Halo games.[/spoiler]

Please for the love of god no, I thought that part of my life was over. inb4 it was Linda

It didn't. Game canon > book canon But that's just my opinion, you choose which canon to follow.

I can't go very in depth cause I don't know 100% like LoA will, but for starters NOBLE Team didn't even really exist until they invented them in the game as there is no mentioning of NOBLE in the books (as far as I can remember). Adding on, they were a "special unit" that received MJOLNIR powered assault armor that has shields, whereas every other company of SPARTAN III's had SPI armor with a cloaking function instead of energy shields. I don't think theres any mentioning of Jorge in any of the books except maybe Halsey's Journal. The Pillar of Autum wasn't even docked on Reach at the time (I think) that Noble 6 supposedly brings Keyes Cortana's data fragment. Theres never any mentioning of another "hyperlethal vector" in the other medias as well. Theres plenty of other reasons, you can research about 343i's DATA DROPS which fixed the canonical errors due to Halo Reach. I'm sure eventually someone will correct me on some of this though.

I don't think it broke canon considering it took place before Halo CE

I'm not even sure if it really did, but from the rants about "Bungee breykin cacoon" I gather that the Spartan III's(Noble Team) weren't supposed to be there.
