{{Title|List of changes in ''Halo: The Fall of Reach'' rereleases}}
{{Status|RealWorld}}
'''''[[Halo: The Fall of Reach]]''''' was first published in 2001, and since then has been adapted multiple times in different formats. Changes to the novels include grammatical fixes, resolved inconsistencies, and new bonus content. Changes in graphic media include modified, omitted, or added dialog and scenes; amalgamated character roles; and visual depictions varying from their original descriptions.

==2010 Tor Books rerelease==
*The rerelease includes an Adjunct section at the end with several new pieces of short fiction:
**[[ONI Directorate Memorandum Interrogation Findings]] - a series of excerpts from the interrogation of [[Subject 386]] by [[Preston Cole|Admiral Cole]] after the [[Battle of the Great Bear]] in [[2530]].
**Word from the [[Third Fleet of Glorious Consequence]] - a message sent by [[Supreme Commander]] [[Luro 'Taralumee]] to the [[Vice Cleric of Zeal]] following the [[Battle of Miridem]].
**A transmission from [[Vice Admiral]] [[Berlin M. Tursk]] to [[Captain (Navy)|Captain]] [[Lucius Jiron]], concerning the capture of Dr. [[Catherine Halsey]] during the Battle of Miridem, as well as [[Operation: WARM BLANKET|the UNSC's response]].
**A message from [[Mike (civilian)|Mike]] to [[Agnes]], regarding [[Ralph-103]]'s upbringing and  reintegration into society following his dismissal from the [[SPARTAN-II program]].
**[[United Nations Space Command Transmission 34670J-17]] - A transmission sent by Captain [[Jacob Keyes]] of {{UNSCShip|Pillar of Autumn}} to [[Vice Admiral]] [[Kopano N'Singile]] of [[Reach]] [[Central Command]] in late [[2552#August|August 2552]], in which Keyes remarks on the final preparations for [[Operation: RED FLAG]] and laments that he is forbidden to inform his crew of the Covenant's presence on the planet. Along with [[Dr. Halsey's personal journal]] and the [[Data Drop]]s, this serves to reconcile the timeline of the Fall of Reach as presented in the novel with that of ''[[Halo: Reach]]''.
**An ONI post-incident investigation report on a possible security breach that may have contributed to the Covenant's discovery of Reach. It involves a transcript of a [[Secure Network|SecNet]] conversation between Sergeants [[Joseph Poteet]] and [[Alasdair Schicker]].
**[[WINTER CONTINGENCY Declaration Supplemental Orders]], an ONI directive containing orders for field agents on Reach in the event of a [[WINTER CONTINGENCY (protocol)|WINTER CONTINGENCY]] declaration.

*The dropship used to transport the 75 Spartan-II trainees to the [[Military Wilderness Training Preserve]] in Chapter 5 is identified as a [[Pelican]] in the original edition, despite its troop bay being far too small for 75 occupants. In the reissue the dropship is changed into a larger [[Albatross]].<ref>'''Halo: The Fall of Reach''', ''page 53'' (2001); ''page 71'' (2010)</ref>

*On page 46 of the original edition, [[Kelly-087]] hands out parts of a map to the 75 Spartan trainees. Then on page 48, when [[John-117]] checks to make sure the children arrived at the lake, he counted only 67. In the re-release, the count of 67 is changed to 74.<ref>'''Halo: The Fall of Reach''', ''pages 46, 48'' (2001); ''pages 62, 65'' (2010)</ref>

*In the original edition, when the Spartans are browsing through the cargo manifest of the freighter ''[[Laden]]'', the ship is said to carry [[list of food and drinks|champagne]] of a "Beta Centauri vintage", implying the [[Beta Centauri]] system had been colonized by humanity.<ref>'''Halo: The Fall of Reach (2001)''', ''page 83''</ref> In the re-release, "Beta Centauri" has been changed to "[[Procyon]]".<ref>'''Halo: The Fall of Reach (2010)''', ''page 104''</ref> This is likely because the system is approximately 390 lightyears from Earth, far beyond the known sphere of influence of humanity and thus unlikely to house a colony; all human colonies depicted in subsequent media are well within 100 lightyears of the Sol system.

*In the original edition, Captain Keyes refers to Ensign [[Ensign William Lovell]] as "Michael" when first meeting him. This has been corrected in the 2010 edition.<ref>'''Halo: The Fall of Reach''', ''page 188'' (2001); ''page 216'' (2010)</ref>

*In the original, a UNSC frigate is referred to as the ''Alliance'', and then shortly thereafter as the ''[[UNSC Allegiance|Allegiance]]''. In the 2010 edition, the ship is referred to as the ''Allegiance'' in both instances.<ref>'''Halo: The Fall of Reach''', ''pages 145, 154'' (2001); ''page 170, 180'' (2010)</ref>

*In the original edition, the ship {{UNSCShip|Leviathan}} is referred to as a cruiser and then later as a carrier. In the 2010 edition, the ship is referred to as a cruiser in both instances.<ref>'''Halo: The Fall of Reach''', ''pages 162, 212'' (2001); ''pages 188, 243'' (2010)</ref>

*On page 19, [[Michael Stanforth]] is said to be a Vice Admiral, and on page 95, it said he is a Rear Admiral. In the 2010 edition, he is referred to as a Vice Admiral in both instances.<ref>'''Halo: The Fall of Reach''', ''pages 19, 95'' (2001); ''pages 33, 117'' (2010)</ref>

*In the original edition, Vice Admiral Stanforth is stated to be ten years Dr. Halsey's senior. "Ten years" is changed to "six years" in the 2010 edition, likely to accommodate Stanforth's and Halsey's birth dates established by the [[ONI memorial]] in ''[[Halo 3: ODST]]''.<ref>'''Halo: The Fall of Reach''', ''page 95'' (2001); ''page 117'' (2010)</ref>

*In the 2001 edition, the ''Pillar of Autumn'' is said to be missing its port-side emergency thrusters, though it later uses them twice. In the 2010 edition, the mention of the thrusters being missing has been removed.<ref>'''Halo: The Fall of Reach''', ''pages 271, 292, 320'' (2001); ''page 307'' (2010)</ref>

*In Chapter 22, [[James-005]]'s left arm is severed by an [[assault cannon]]. In the original edition, he is said to salute with left mere pages later, despite the hand being missing. In the 2010 re-release, he salutes with his right hand.<ref>'''Halo: The Fall of Reach''', ''pages 208, 210'' (2001); ''page 241'' (2010)</ref>

*In the original edition, the first time John-117 encounters [[Sangheili]] warriors in the battlefield is on [[Gamma Station]] during the Fall of Reach. In addition, the UNSC is depicted as not having any first-hand intelligence on the species prior to the battle; Dr. Halsey only hypothesizes about their existence.<ref>'''Halo: The Fall of Reach''', ''page 242, 309'' (2001)</ref> This has been universally ignored in later media, which depict Sangheili as commonplace throughout the war. The 2010 reissue thus modifies references to the Sangheili having never been encountered by humanity prior to the Fall fo Reach. When Dr. Halsey briefs the Spartans for [[Operation: RED FLAG]] in chapter 26, the line
::''"We believe there is a 'race' of field commanders, which we are currently calling 'Elites'"''<ref>'''Halo: The Fall of Reach (2001)''', ''page 242''</ref>
::is changed into:
::''"We also know that there is a 'race' of field commanders we have historically called 'Elites'"''.<ref>'''Halo: The Fall of Reach (2010)''', ''page 275''</ref>
:During the Spartans' mission to [[Reach Station Gamma]] in chapter 35, the following sentence:
::''"These must be the elite warrior class Dr. Halsey had conjectured. The Covenant's best? They were about to find out."''<ref>'''Halo: The Fall of Reach (2001)''', ''page 309''</ref>
::is changed into:
::''"These were Elites - the iron heart of the Covenant. Would they best the Spartans this time? They were about to find out."''<ref>'''Halo: The Fall of Reach (2010)''', ''page 347''</ref>

*In chapter 29, the sentence
::''"From this distance, the ''Pillar of Autumn'' could have been mistaken for an elongated frigate."''<ref>'''Halo: The Fall of Reach (2001)''', ''page 271''</ref>
::is changed into:
::''"From this distance, the ''Pillar of Autumn'' could have been mistaken for a Marathon-class carrier."''<ref>'''Halo: The Fall of Reach (2010)''', ''page 307''</ref>
:::This line is still erroneous, as the ''[[Marathon-class cruiser|Marathon]]'' is actually a class of cruiser, not a carrier.

*The number of the Covenant ships present at the battle over Reach is changed from 314 to "well over seven hundred" in the 2010 reissue.<ref>'''Halo: The Fall of Reach (2010)''', ''page 333''</ref> This is probably due to a hyperbolic line spoken by [[Fleet Admiral]] [[Terrence Hood]] in ''[[Halo 2]]'', in which he states that the fleet that destroyed Reach was "fifty times" the size of the [[Fleet of Sacred Consecration]], being taken at face value. However the change is only made once; all other instances state the fleet consists of 314 ships. 

*During Blue Team's mission to Reach Station Gamma, the original edition states that Kelly shouted "All secure!" while the Spartans' Pelican prepares for maneuvering, even though she is not aboard the Pelican. "Kelly" has been corrected to "Linda" in the reissue.<ref>'''Halo: The Fall of Reach''', ''page 306'' (2001); ''page 344'' (2010)</ref>

*In the 2001 edition, Admiral [[Roland Freemont]] recalls all UNSC warships in the "REACH, JERICO ''[sic]'' and TANTALUS systems" to the defense of Reach.<ref>'''Halo: The Fall of Reach (2001)''', ''page 289''</ref> The 2010 reissue changes the spelling of "JERICO" to "JERICHO", but the rest of the line remains unchanged.<ref>'''Halo: The Fall of Reach (2010)''', ''page 326''</ref>

==2011 Definitive Edition rerelease==
*The number of ships at Reach is changed back from 700 to the original 314.<ref>'''Halo: The Fall of Reach (2011)''', ''page 343''</ref>

*The references to the Tantalus and Jericho systems have been removed.<ref>'''Halo: The Fall of Reach (2011)''', ''page 335''</ref> This is because [[Tantalus]], like Reach, is a planet in the [[Epsilon Eridani system]],<ref>''[[Halo Encyclopedia (2009 edition)]]'', page 287</ref> whereas the "Jericho system" ([[Lambda Serpentis system|Lambda Serpentis]]) had been invaded by the Covenant in [[2535]], as depicted in the novel's prologue.

==''Halo: Fall of Reach'' comic series==
===General changes===
*There are several changes regarding various characters' hairstyles.
**[[Kelly-087]] is depicted with brown hair in the Spartans' first day of training, whereas in the novel, she had her hair dyed blue at the time. She is also depicted with a bob-cut hairstyle in later scenes of childhood training; according to [[Dr. Halsey's personal journal]], Kelly, like the other Spartans, had her head shaven a few days after her induction into the program, with an entry describing how she had to be held down for the barbers to finish cutting her hair. Kelly is also depicted with medium-length hair in the scenes following the augmentation procedures; in the book, her hair had yet to grow back after the augmentations at the time of the Spartans' mission to [[Eridanus Secundus]], and even later in her career she is described with a short military cut.<ref>'''Halo: The Fall of Reach''', ''page 6'' (2001 edition)</ref>
**[[Linda-058]] maintains a rather long haircut in the comic, while the novel describes her as having close-cropped hair.<ref name="tfor78">'''Halo: The Fall of Reach''', ''pages 78-79'' (2001 edition)</ref>
**The comic consistently portrays Dr. Halsey with black hair; the novel mentions that her hair had started graying by 2525<ref>'''Halo: The Fall of Reach''', ''page 96'' (2001 edition)</ref> and had become completely gray by 2552.<ref>'''Halo: The Fall of Reach''', ''page 224'' (2001 edition)</ref>
*There are a number of differences involving the attire of characters.
**The comic does not depict Dr. Halsey with glasses at any point, whereas the book describes her as wearing glasses in most of her appearances.
**During the Spartan-II trainees' mission in the [[Military Wilderness Training Preserve]], the Spartans are shown wearing their standard training fatigues. In the novel, they wear heavy parkas because of the cold.
**In Vice Admiral Stanforth's initial briefing on the Covenant and the destruction of [[Harvest]] in ''Boot Camp'', Stanforth wears a green uniform vaguely similar to the standard [[UNSC Navy Service Uniform|Navy service uniform]]. Mendez and Halsey are wearing similar outfits, teal and light gray in coloration, respectively. The novel describes Stanforth and Mendez as wearing black dress uniforms, with Mendez's chest covered with decorations while Stanforth's uniform is undecorated; Halsey is described as wearing gray slacks and a black shirt with her glasses hanging about her neck on a gold chain.<ref>'''Halo: The Fall of Reach''', ''page 95''</ref>
*Like ''[[Halo Wars: Genesis]]'', the series depicts space battles with considerable artistic license. In the novel, space engagements are consistently described as occurring over distances of many thousands of kilometers. For example, when the ''Unrelenting'' performs a slipspace jump near the ''Commonwealth'', a distance of 3,000 kilometers is considered to be dangerously close, enough to trigger collision alarms. Meanwhile, in the comic, ships and entire fleets exchange fire within visible range, often merely hundreds of meters from one another. This is simply a pragmatic storytelling approach and does not reflect the actual nature of space battles in the ''Halo'' universe.
*[[Slipspace]] is depicted as a bright, blue-white tunnel with streams of lines and quadrilateral figures; in the novels, slipspace is described as being pitch black.

===Volume-specific changes===
====''Boot Camp''====
*Issue 1 features a new prologue centered on [[Robert Watts|Colonel Watts]]' actions during [[Operation: TREBUCHET]], replacing the novel's prologue featuring Blue Team battling an Unggoy horde on [[Jericho VII]].
*The events of the first chapter are depicted with a number of differences. In the comic, Dr. Halsey is already awake and on the ''[[Han]]''<nowiki>'</nowiki>s bridge by the time [[Jacob Keyes]] wakes up from cryo. In the book, Halsey awakens immediately after Keyes. Keyes is also shown wearing clothes upon waking, whereas in the novel, both Keyes and Halsey are naked while in cryo; similar concessions are applied to all scenes involving cryosleep in visual ''Halo'' media. ''Han''<nowiki>'</nowiki>s trip to [[Eridanus II]] is also truncated, and the shuttle's gravitational slingshot maneuver around a local gas giant is omitted.
*[[Eridanus II]] is depicted with two moons. In the [[Bestiarum]], the planet is established to have a single natural satellite, [[Ehilend]].
*In Issue 1, [[Vice Admiral]] [[Ysionris Jeromi]] sends Halsey [[UNSC Priority Transmission 09872H-98|his results]] on the [[SPARTAN-II augmentation procedures]] just after the children are kidnapped in 2517. In the book, he sends the results in 2525, just before the surgeries begin.
*A new scene is included depicting the UNSC ''Dartmouth'' under a pirate attack by Watts' ship.
*A new scene is added in which John dreams of Dr. Halsey waking him up in his first day of training.
*The scenes depicting the Spartans' first days of training are compressed into a montage and the two consecutive "Ring the Bell" exercises are omitted as the impetus for John befriending Sam and Kelly.
*In the novel, [[Franklin Mendez|CPO Mendez]] gives John no answer when the Spartan asks if the dead candidates' lives were wasted or spent. In the comic, he avoids the question by telling John to get some rest.
*When CPO Mendez and Dr. Halsey enter the titanium mine where the newly-augmented Spartans are training, Mendez's Warthog lacks a turret. In the novel, the Warthog is mentioned as being equipped with a missile launcher.
*The incident aboard the UNSC ''Atlas'' with the four ODSTs in the gym is omitted.
*It is said that Colonel Watts defected from the UNSC in 2512. This contradicts the background first given for the character in the ''[[Halo Encyclopedia (2009 edition)]]'' and later Watts' Halo Waypoint article, with the former establishing that Watts already led the Eridanus rebels in 2494 and the latter stating that the colonel went turncoat as early as the 2480s.
*John is shown having a nightmare while sleeping aboard the [[Laden]]; in the novel he merely dreams of [[gravball]] and a coin spinning in the air.
*In Issue 3, John pushes Sam out of the line of fire and is wounded during the [[assault on Eridanus Secundus]]. In the novel, John is merely grazed by a lucky shot.
*The specifics of the Spartans' capture of Colonel Watts differs from the novel. In the comic book, Watts is shown entering a safe room before the Spartans capture him, which does not occur in the novel. The crate Watts is forced into is thrown off his apartment's balcony in the comic, whereas in the novel, the Spartans slide it down by a rope.
*The first transmission from the [[Covenant]] to humanity that tells them their destruction is the will of the gods is an audio message in the novel. In the comic it is a video, with the [[Prophet of Regret]] personally appearing to announce it to them.
**In the same scene, the Covenant ship first encountered at Harvest is depicted as a {{Pattern|Ket|battlecruiser|}} or [[Zanar-pattern light cruiser|''CRS''-class cruiser]], presumably ''[[Rapid Conversion]]''. In ''Halo Wars: Genesis'' and ''[[The Impossible Life and the Possible Death of Preston J. Cole]]'', the ship encountered by [[Battle Group 4]] is a [[Rasus-pattern interdictor|super-destroyer]].
*John's last meeting with CPO Mendez and the latter giving the former back the [[quarter]] that decided his entry into the SPARTAN-II program is omitted.

====''Covenant''====
*''[[Unrelenting]]'' is depicted as a ''CRS''-class or ''Ket''-pattern cruiser in the comic, while the book describes it as a sleek ovoid a third the mass of the ''Commonwealth'', with a single lateral line running fore to aft.<ref>'''Halo: The Fall of Reach''', ''page 105''</ref>
*In the comic, the [[Damascus Testing Facility]] is depicted as a [[space station]] orbiting [[Chi Ceti IV]]; the novel and Dr. Halsey's journal describe it as a terrestrial base located deep underground.
*[[Longsword Squadron Delta]] survives the detonation of the Shiva missile fired at the ''Unrelenting'', whereas in the novel the Longswords are consumed by the explosion, as they were intentionally sacrificed as a diversion.
*The Spartans' assault on ''Unrelenting'' is decidedly different.
**The comic depicts John, Sam, and Kelly jumping toward the ship—shown within clearly visible distance—without apparent thrusters. The three approach the ''Unrelenting'' in a tight formation while discussing their entry strategy and simply glide into the ship. In the novel, the distances involved are much greater. Even though the Spartans use [[thruster pack]]s, there is a high likelihood of missing the ship which is traveling at a high velocity, forcing the Spartans to conduct careful maneuvers to intercept it. In the novel, the Spartans do not approach ''Unrelenting'' in a closely packed group and do not converse until regrouping on the Covenant ship's hull.
**In ''Covenant'', only John, Kelly, and Sam take part in the assault on ''Unrelenting'', as they are the only three able to don their Mjolnir armor in time. In the novel, all the Spartans take part in the assault, but only John, Kelly, and Sam are able to get aboard the enemy vessel.
**In the book, ''Commonwealth'' fires a salvo of Archer missiles as decoys to cover the Spartans' approach; this is not depicted in the comic. The warheads used by the Spartans during the boarding operation are also different; in the comic, the Spartans use nuclear missiles, perhaps [[Shiva-class nuclear missile|Shivas]]. In the book, they use [[ANVIL-II Air-to-Surface Missile]]s, which have conventional warheads. As seen in [[:File:Anvil II wing.JPG|this image]], the missiles used in the comic are far too large to be ANVIL-IIs.
**While escaping the ''Unrelenting'', John and Kelly encounter several Jackals; this is not described in the book.
*In the novel, there are four surviving Marines in [[Corporal Harland's fireteam]] at the [[Battle of Sigma Octanus IV]]. Private [[Walker]] freezes, forcing Private [[Cochran]] to shoot down two pursuing Banshees with Walker's rocket launcher. In the comic, Cochran is not present. Instead, Walker is able to break out of his fugue and shoot down the lone Banshee pursuing them.
*The initial skirmish above Sigma Octanus IV, the [[Keyes Loop]], and Keyes' promotion to captain are omitted.
*In the novel, Blue Team's fight with the Hunters in the [[Côte d'Azur Museum of Natural History]] is won by using shredder rounds to break the floor beneath their feet then pushing a stone monolith into the hole to crush them. In the comic, the battle is won by using two grenades to crack the monolith, then breaking it, so that the upper half falls and crushes the Hunters.

====''Invasion''====
*In the novel, John meets Cortana for the first time when she is plugged into his neural interface, where the two have a short conversation. In the comic, Cortana is introduced to John via hologram.
*In Issue 4, while aboard Gamma Station, John and Linda encounter three Marines: Staff Sergeant [[Avery Johnson]], Private [[Bisenti]], and Private [[O'Brien (Reach)|O'Brien]]. In the novel, they are accompanied by a fourth Marine, Private [[Wallace Jenkins]].
*In Issue 4, a [[Sangheili Zealot]] impales Linda on an energy sword. In the novel, she is shot five times by plasma projectiles.
*''Invasion'' adds a subplot with [[Red Team]] being deployed on Reach to defend [[Orbital Defense Generator Facility A-331]]; this sequence is not present in ''The Fall of Reach'', but is instead loosely adapted from ''[[Halo: First Strike]]'' with significant changes from the original narrative.
**The [[Bravo 001|Spartans' Pelican]] is piloted by Fred and Kelly with Joshua manning its troop bay machine gun; in ''First Strike'', no rear gun is in mentioned and the Pelican is piloted by a Naval aviator, [[Mitchell]].
**The Longswords escorting the Pelican are omitted.
**The dropship is shot down by [[Banshee]]s rather than the [[Seraph]]s described in the novel.
**The Pelican crashes with the Spartans still onboard; in ''First Strike'', the Spartans are forced to eject at high altitude as the Pelican careens toward a mountainside at supersonic velocity. The subsequent part of the book detailing the Spartans' regrouping and advance on the generator complex is also omitted.
**The events at the generator facility are markedly different, including the Spartans encountering a single delirious Marine as opposed to the four moderately shaken survivors of [[Charlie Company]].
**In the comic, all the Spartans of Red Team remain at ODG A-331 when the Covenant launch their second major assault on the facility; in ''First Strike'', only [[Beta-Red|Team Beta]] remains at the complex by the time of the Covenant attack.
*In an added scene, the Master Chief dreams of his and Kelly's young selves reflecting on the possibility of returning home someday while in cryosleep.

==''Fall of Reach'' animated adaptation==
The animated adaptation, like the comic series before it, features several changes, some of which are necessitated by the medium. The greatest change is that, in order to keep the length of the series to approximately one hour, this adaptation only covers the first half of the story ("Reveille" and "Boot" in the novel; "Bootcamp" and the first two issues of "Covenant" in the comics). This is also because that the animated series was released alongside ''[[Halo 5: Guardians]]'' and serves to introduce to the [[Blue Team]] roster featured in the game (John-117, Fred-104, Kelly-087, and Linda-058), whereas the novel and comic adaptation serve as prequels to ''[[Halo: Combat Evolved]]''. Due to their overwhelming number, simple omissions or truncations are not listed below. Changes which are in keeping with one previous incarnation of the story but not the other are listed as such. 
*The series opens and closes with new scenes in which Blue Team meets on a glassed Reach and reminisces about their past at some point before the events of ''Halo 5: Guardians''.
*Rather than the third-person perspectives of the source material, the three parts of the series are narrated from the perspectives of Catherine Halsey, Sam-034 and Kelly-087, respectively.
*The characters' attire and physical characteristics generally conform to their comic representations rather than their descriptions in the novel. Notably:
**Halsey's civilian attire while observing John is identical to that from the comic.
**Halsey is depicted without glasses.
**Kelly is abducted with her hair in its natural brown rather than dyed blue. She is also depicted with brown eyes, whereas the novels and all other prior depictions portray her with blue eyes. Fred-104 is similarly depicted with brown eyes; he is described as having blue-green eyes in the novels.
**In the novel, Samuel-034 is described as having darkly tanned skin and green eyes. After the Spartans' augmentations, he is noted as having grown his hair out to three centimeters. In the animated series, although his hair color conforms to the novel, he has a pale complexion and blue eyes, and maintains a short buzz cut until his death.
**Unlike the comic adaptation, in which the 14-year-old John-117's face is always partially obscured whenever he appears without a helmet, his face is fully shown in the animated series.
*Keyes' revival on the ''[[Han]]'' in shown in the manner of the comic, rather than the novel.
*John and the other boys play King of the Hill on series of platforms, rather than a literal hill.
*Halsey tosses the [[quarter]] in the air multiple times (with John correctly estimating which side it will land on each time), whereas in the novel she flips it only once, and John snatches it out of the air himself, after which Halsey never touches the coin again.
*When Halsey first addresses the Spartan cadets, their hair has been buzzcut. In the novel and the comic, they still wear their civilian haircuts at this time, with their hair not being shorn until several days into the program, as attested by [[Dr. Halsey's personal journal]].
*[[Jorge-052]] makes a brief cameo in which he is struck by a [[humbler stun device]] after correcting a [[drill instructor]] for mispronouncing his name.
*Whereas all prior sources explicitly state that all 75 trainees survived until the augmentations, the series depicts the deaths of three Spartan-II candidates during training; Halsey's narration refers to this in an uncharacteristically callous manner as "removing the chaff from the wheat". Halsey later states that 27 of the children (as opposed to 30 in all prior material) were killed by the procedures; she notes these fatalities as representing 36% of the total candidates. However, this percentage is [[List of inconsistencies in the Halo series#Halo: The Fall of Reach - The Animated Series|internally inconsistent]], as it would be accurate only if all 75 underwent the procedures.
*The "ring the bell" exercise is notably modified from the novel's depiction: it takes place well into training rather than on the first day; the obstacle course is indoors, rather than outdoors; and Fred and Linda are added to John's team. Only the first bell exercise is shown.
*The mission in the [[Military Wilderness Training Preserve]] takes place in below-freezing conditions, as described in the novel, rather than the temperate environment of the comic. The trainees wear thin body suits, rather than the novel's heavy parkas. 
*During John's debriefing after the wilderness mission, a brief scene is added in which Halsey tells John that the 300 Spartans at Thermopylae were betrayed, though their sacrifice saved Greece. John asks Mendez the highest rank he can attain, and is told that the highest Navy non-commissioned rank is [[Master Chief Petty Officer]]; John vows to achieve this rank.
*As in the novel, Vice Admiral [[Ysionris Jeromi]]'s report is received immediately before the augmentation procedures in 2525, though it is an audio message rather than the text file of the novel or the video message of the comic.
*As in the comic, CPO Mendez tells John to get some rest when asked whether the Spartans' lives were spent or wasted. A new scene is added in which immediately following this conversation, Sam attempts to comfort John and invites him to the shooting range. John declines the offer and heads to the gym, setting up his confrontation with the ODSTs, events which take place more than three weeks later in the novel.
*Sam's narration states that John was still struggling with the loss of his subordinates when he fought the ODSTs, implying that he was not in control of his emotions. John is also shown climbing on top of and repeatedly pummeling a fallen ODST, fighting far more aggressively and offensively than is depicted in the novel, in which he fights is a restrained, defensive manner. The fight takes place spontaneously entirely on the floor of the gym, rather than in the boxing ring on the orders of a Marine sergeant as in the novel. 
*An added scene shows Halsey watching the fight on a monitor as it takes place, observing John's actions and physical responses with curiosity while completely unfazed by the brutality he is inflicting. As with her dismissal of the trainees' deaths earlier in the adaptation, this indifference toward bloodshed is a notable departure from her portrayal in the original novel and most other material.
*As in ''Boot Camp'', Colonel Watts is said to have defected in 2512.
*As in the comic, John has a nightmare while sleeping aboard the ''[[Laden]]''.
*In lieu of the [[MA2B assault rifle]]s they use in the novel and the comic, Blue Team uses [[M7S SMG|M7S silenced submachine guns]] during their mission to Eridanus Secundus. Correspondingly, the Insurrectionists use unsuppressed [[M7 SMG]]s instead of [[HMG-38 heavy machine gun]]s. Linda also uses an M7S instead of her custom-tuned [[SRS99C-S2 AM sniper rifle]].
*As in the comic, John is wounded by one of Colonel Watts' guards while pushing Sam out of the line of fire rather than by a stray shot.
*In an added conversation, Sam scolds John for sacrificing himself for him, stating, "A queen doesn't sacrifice everything to collect a pawn." To this John replies, "All the pieces go back in the same box when the game is done," in reference to Cortana's first words. 
*A shortened version John's reunion with Jacob Keyes takes place in November 2525, just before the Spartans are told of the events at Harvest, rather in July 2552 following the [[Battle of Sigma Octanus IV]] (which is omitted from the series).
*The Harvest briefing takes place immediately following the Eridanus Secundus raid rather than nearly two months later. The Spartans are wearing [[black body suit]]s rather than [[UNSC Navy Dress Uniform|dress uniforms]].
*As in the comics, the first transmission from the [[Covenant]] to humanity is a video. However, whereas the Prophet of Regret appears unobscured in the comic, the animated series shows only his silhouette.
*As in the comic, the ''[[Unrelenting]]'' is depicted as a conventional cruiser.
*As in the novel, all of [[Longsword Squadron Delta]] is intentionally sacrificed and vaporized by the nuclear explosion.
*As in the novel, [[Damascus Testing Facility]] is an underground facility on the surface of [[Chi Ceti IV]].
*The Spartans are outfitted with distinct helmets: John's, Fred's, Kelly's, and Linda's resemble hybrids of the standard Mark IV model and those they wear in ''Halo 5'' ([[Mark VI MOD]], [[CENTURION-class Mjolnir|Centurion]], [[HERMES-class Mjolnir|Hermes]], and [[ARGUS-class Mjolnir|Argus]], respectively). Sam wears a [[CQB-class Mjolnir|CQB]] helmet, while unidentified background characters wear other variants; ironically, the mainline Mark IV helmet is not shown. This is contrary to both the novel and the comic, in which the Spartans are issued identical helmets.
*John, Sam, Kelly, Fred, and Linda board the ''Unrelenting'', as opposed to the novel (in which all 33 Spartans are deployed but only John, Sam, and Kelly succeed) and the comic (in which only John, Sam, and Kelly even attempt to board); i They do so using thrusters built into their MJOLNIR armor - a feature of the [[MJOLNIR Powered Assault Armor (GEN2)|MJOLNIR <nowiki>[GEN 2]</nowiki>]] in ''Halo 5: Guardians''. Sam wields an anachronistic [[BR85HB battle rifle]] from ''Halo 4'', whereas the other Spartans carry the weapons they use in ''Halo 5''.
*Unlike the novel and the comic, in which the Spartans exclusively encounter thin-headed Ruuhtian [[Kig-Yar]] aboard ''Unrelenting'',<ref>'''Halo: The Fall of Reach''', ''page 120''</ref> Blue Team first run into and kill an [[Unggoy]]. They then encounter a [[Sangheili]] in a hangar bay, where they charge at each other and Sam is shot in the chest; previous adaptations have Sam shot as a door opens in a narrow corridor. Finally, in the core they engage numerous Ibie'shan Kig-Yar, the stout-headed subspecies introduced in ''[[Halo 4]]''.
*In Kelly's added narration she states that, "We knew we weren't finishing the fight. We were just getting started," paraphrasing John's final words in ''Halo 2'' and ''Halo: Combat Evolved'', respectively.
*While in the novel the Spartans use the warheads from regular [[Anvil-II air-to-surface missile|Anvil-II]] missiles to destroy the ''Unrelenting'', in the animated series the ''Commonwealth's'' Pelicans carry [[HAVOK tactical nuclear weapon]]s which the Spartans use to destroy the ship by attaching one to the ''Unrelenting's'' reactor and detonating it. However, like in the novel, they do use a countdown timer attached to the warhead to set it off.
