'''''Halo: First Strike''''' is a [[Halo novels|''Halo'' novel]] authored by [[Eric Nylund]]. It was published in December 2003,<ref name="randomhouse">[http://www.randomhouse.com/catalog/display.pperl?isbn=9780345467812 '''Random House''': ''Halo: First Strike by Eric Nylund'']</ref> after being written in a period of sixteen weeks.<ref name="xbox.com3">[http://www.xbox.com/en-US/games/h/halo2/spotlight2.htm '''Xbox.com''': ''First Strike Author Eric Nylund Q&A'']</ref>

''Halo: First Strike'' fills the gap between ''[[Halo: Combat Evolved]]'' and ''[[Halo 2]]'', in addition to continuing the story of the [[SPARTAN-II Program|Spartans]] and [[Catherine Halsey|Dr. Halsey]] on [[Reach]] where ''[[Halo: The Fall of Reach]]'' left off. The story is continued directly in ''Halo 2'' and the subsequent novel ''[[Halo: Ghosts of Onyx]]''. ''First Strike'' also ties up several unresolved plot threads, including how Sergeant [[Avery Junior Johnson|Johnson]] survived the attack of [[the Flood]].

The novel, along with ''[[Halo: The Fall of Reach|The Fall of Reach]]'' and ''[[Halo: The Flood|The Flood]]'', was reissued in [[2010]] by [[Tor Books]], with the new version including some content updates.<ref>[http://kotaku.com/5543023/halo-novel-trilogy-to-be-republished-with-updates-new-content '''Kotaku''': ''Halo Novel Trilogy to be Republished with Updates, New Content'']</ref>

battle to prevent the alien construct from falling into the enemy's clutches.'' 
''Now, everything depends on the Spartan known as the "Master Chief." Yet even with the aid of the artificial  intelligence known as Cortana, the Master Chief will be hard-pressed 
to rescue survivors and evade the Covenant ships patrolling the remains of Halo in debris-strewn space.''

'''
2552. The theocratic military alliance known as the Covenant is showing no mercy as it continues to assault every human world it encounters, but in the way lies humanity’s greatest champion, the super-soldier Spartan John-117—the Master Chief. Together with his AI companion Cortana and the last remaining Spartans, the galaxy-spanning fight rages on two fronts following the destruction of the human military stronghold Reach by Covenant forces and the mysterious artificial ringworld known as “Halo” at the hands of the Master Chief.

One faction—a squad of Spartans lead by Blue Team’s Fred-104 and Kelly-087—is trapped on the glassed surface of Reach, the only planet they’ve ever known as home. And beneath this ruined world, Dr. Catherine Halsey has discovered an ancient secret… one that could alter the course of the war. Meanwhile, the Master Chief and Cortana lead a second group toward a gathering of Covenant warships, as the United Nations Space Command’s worst nightmare has finally come true: the Covenant has discovered the location of Earth and is forming a massive fleet to utterly destroy it, as well as all who oppose the indomitable will of the Prophet…}}

==Plot synopsis==
{{Spoiler/begin}}
===Section 0: Reach===
The prologue begins during the [[Fall of Reach]] and flashes back to Chapter 34 of ''[[Halo: The Fall of Reach]]'', where [[Jacob Keyes|Captain Jacob Keyes]] informs [[John-117|Master Chief Petty Officer John-117]] about the unsecured NAV database. John makes [[Frederic-104]] the leader of [[Red Team]] and orders him to take the other [[SPARTAN-II Program|Spartan-IIs]] down to [[Reach]] to protect the generators powering the [[Orbital defense platform|orbital MAC guns]].

The narrative follows Red Team as they ride a [[Pelican]] down to the surface. After [[Seraph]] fighters hit [[Mitchell|their pilot]] with plasma fire, Red Team jumps from the disabled vehicle. Falling at terminal velocity, their impact with the ground kills four Spartans and leaves many more seriously injured. Most lose their weapons and ammunition; Fred and [[Kelly-087]] improvise using rocks until they are able to loot Covenant weapons from a group of [[Kig-yar|Jackals]] they kill. The Spartans group up with the remaining four [[UNSC Marine Corps|Marines]] of [[Charlie Company]]. The Marines summarize how the battle went, explaining that they were the only ones who survived.

[[Vice Admiral]] [[Danforth Whitcomb]] contacts Fred and orders the Spartans to extract him and his staff, claiming to be the current officer in charge of the defense of Reach. Fred subdivides Red Team to complete the mission: Beta Team is to defend the generators, Gamma Team is to extract the Admiral, and Delta Team is to secure a fallback point at [[CASTLE Base]]. Fred then takes Kelly and [[Joshua-029]] (comprising Alpha Team) on a mission to destroy a large [[Covenant Empire|Covenant]] encampment in the adjacent valley. Taking three [[Type-26 Ground Support Aircraft|Banshees]], they deliver a [[Fury Tactical Nuclear Weapon|Fury tactical nuke]] into [[Unidentified cruiser (Particular Justice)|a Covenant ship]]. During the assault, the Covenant shoots down Joshua's Banshee and he is presumed dead. Fred and Kelly complete the mission without further complications.

Despite the Spartans' efforts, the Covenant overruns the reactors on Reach and their fleet begins [[glassing]] the planet. Fred - refusing to sit around and die - comes up with a plan. He and Kelly take their captured Banshees, and together they fly away.

===Section 1: Threshold===
The narrative moves to the debris field of [[Installation 04]], right after the events of ''[[Halo: Combat Evolved]]''. Aboard the [[GA-TL1 Longsword|Longsword]] that [[Cortana]] and the Master Chief used to escape the ring's destruction, the pair converses. The Chief insists that Cortana repeat her scans of the debris field for any signs of life.

Cortana eventually detects [[Fleet of Particular Justice|a battle group]] of seven Covenant starships and a flagship. She also finds three [[Cryo chamber|cryo-chambers]] that the [[UNSC Pillar of Autumn|''Pillar of Autumn'']] jettisoned before its crash on Halo. While she moves the Longsword toward the cryotubes, she discovers a Pelican hiding nearby. As the Chief retrieves the cryotubes and returns to the Longsword, the Pelican takes off and attacks the lead Covenant starship, diverting attention away from the Longsword. The two small ships link up, and several survivors exit the Pelican: [[Avery Junior Johnson|Sergeant Johnson]], [[Orbital Drop Shock Trooper|ODST]] [[Locklear|Corporal Locklear]], [[Shiela Polaski|Warrant Officer Shiela Polaski]],<ref>'''[[Halo Legendary Crate]]''', ''[[Halo Legendary Crate/Data Drops|Data Drop #10]]''</ref> and an [[Office of Naval Intelligence|ONI]] [[Lieutenant]], [[Elias Haverson]]. The Master Chief - having seen a video of Johnson being infected - slams him into the bulkhead and aims Johnson's pistol squarely at his head, waiting for an explanation on how he survived. Johnson, through his own words, says that he must not have tasted good to [[Flood|the Flood]]. After confirming with Cortana that Johnson isn't infected, Master Chief releases him.

Together, the group uses the Longsword to board the flagship, called ''[[Ascendant Justice]]''. They fight their way to the bridge, and along the way, plug Cortana into the vessel's computer. Cortana decompresses most of the vessel's decks, killing most of the crew. She then learns that they're running out of time, as this fleet is a prelude to [[Hierarchs|a Covenant dignitary]]'s arrival at Halo, along with [[High Charity|their vessel]] and a [[High Charity Defense Fleet|massive escort]]. The group makes it to the bridge, only to confront a Spec Ops [[Sangheili|Elite]] wielding an [[Type-1 Energy Weapon/Sword|Energy Sword]], whom the Master Chief defeats with the help of Johnson and Locklear, sustaining a slight injury. The defeat of the Elite warrior allows the humans to gain complete control of the Covenant flagship.

In the confusion between the other vessels, the ''Ascendant Justice'' enters [[Slipstream space|Slipspace]]. The group argues about where to go next, but ultimately, the Chief persuades them all to return to Reach; first, because the [[United Nations Space Command Emergency Priority Order 098831A-1|Cole Protocol]] forbids them from taking a Covenant vessel to [[Earth]] directly; second, because the Chief secretly wants to see what became of his fellow Spartans. Haverson sends Johnson, Locklear, and Polaski to the Longsword to retrieve its gear. When they reach the Longsword, Johnson contacts the Chief, informing him that one of the cryotubes contains a Spartan.

Meanwhile, on Earth, at UNSC [[HIGHCOM Facility Bravo-6]] in [[Sydney]], [[Wagner|Lieutenant Wagner]] briefs the [[UNSC Security Council]] on Reach's destruction and concludes that they cannot try to retake the planet, and instead, must prepare for the final defense of Earth. All Spartans and vessels are assumed destroyed, though they do know that the {{UNSCShip|Pillar of Autumn}} escaped Reach. [[Colonel]] [[James Ackerson]] - who was supposedly reassigned due to Cortana's actions - escaped reassignment and is serving on the Security Council. Ackerson appears almost gleeful that Reach has fallen, but crosses a line when he denounces the Spartans as "freaks", earning a firm rebuke from [[Fleet Admiral|Admiral]] [[Terrence Hood|Hood]]. [[Major General|General]] [[Nicolas Strauss|Strauss]] considers sending a recon unit to check for survivors, but Ackerson insists that any such mission would not only be suicidal, but pointless, as the Covenant would have left none.

===Section 2: Defense of Castle Base===
The narrative returns to Reach where Kelly and Fred, after destroying the Covenant ship, crash-land their Banshees into a pair of Hunters, confusing one and disabling the other's gun. They steal a pair of Wraith tanks and blast their way into CASTLE Base under [[Menachite Mountain]]. There, they meet up with the surviving Spartans of Delta Team: the injured [[Isaac-039]], [[Vinh-030]], and [[William-043|Will-043]], as well as [[Catherine Halsey|Doctor Catherine Halsey]], who treats their injuries. Dr. Halsey sends them to retrieve some new weapons: the [[BR55 Battle Rifle]] and the [[M6C Personal Defense Weapon System|M6C]] magnum sidearm.

At the lab, Halsey discovers Colonel Ackerson's plans, which contain extensive lists on "Her Spartans", a star chart reference, and a third file labeled "[[KING UNDER THE MOUNTAIN]]". Before she can access these, however, a UNSC [[Smart AI|AI]] named [[Araqiel]] appears and attempts to stop her by threatening to kill her or the Spartans. She destroys it using a bypass code she herself had programmed, but causes some concern with [[Kalmiya|her personal AI]]. The Covenant then invades the base, and the Spartans and Halsey escape to the old titanium mines beneath CASTLE Base right before its destruction, which blocks their only exit. Having no other alternatives, the Spartans and Halsey venture deep into the tunnels.

Inside, the Spartans receive armor upgrades and Fred discovers several symbols, which ultimately open a large tunnel, leading into an even larger room. In the room's center, they find a [[Forerunner crystal]]. While walking toward it, the Spartans and Halsey discover that it bends the space around them, and if brought into slipspace, would allow them to travel longer distances with the same amount of energy. They retrieve the crystal, but because of the radiation it is emitting, the Covenant is able to find them. The Covenant land forces inside the room using reversed [[gravity lift]]s, forcing the humans to retreat. Fred orders Isaac and Vinh to stay behind to form a rearguard action, but the two are overwhelmed and killed. The remaining Spartans and Dr. Halsey continue to flee through the tunnels. As the Covenant follows them, they meet a dead end. 

===Section 3: Rescue===
Johnson, who discovered that one of the cryotubes contains [[Linda-058]], reports that the others contain Marines that have died due to cryotube malfunction. Master Chief heads to the Longsword, where he strips pieces from the craft to reinforce a [[Dextro Xur-pattern Spirit|Covenant dropship]] they are going to use. As they enter the flagship's hangar, Master Chief and Johnson witness Polaski piloting the Covenant dropship as practice. As they enter [[Epsilon Eridani system|Epsilon Eridani]], the crew sees what happened to Reach after the Covenant glassed the planet. Cortana moves the flagship closer as they notice that the Covenant "missed" a spot. The small Covenant fleet in the system - consisting of a dozen cruisers, two carriers, and three [[Seraph]] squadrons - asks why a flagship is at Reach. The survivors hear a UNSC [[COM#UNSC COM channels and systems|E-band]] transmission: a six-note tune, "[[Oly Oly Oxen Free]]". No one on the bridge recognizes it - except the Master Chief. 

The narrative then flashes back to [[2523|July 14, 2523]], when the young Spartans played capture the flag against [[Tango Company]]. Despite Tango Company's use of live-fire rounds, the teenage Spartans capture the flag and win the "game". While hiding from Tango Company Marines searching for the flag, John uses the "Oly Oly Oxen Free" signal to inform his teammates that all is clear.

Back on ''Ascendant Justice'', the human crew debates whether they should travel down to Reach in the reinforced Covenant dropship. Cortana searches for a spot that they can later use as an extraction site to pick up the crew. On the way down, cruisers surround the crew in their dropship, but ultimately let them pass. While Cortana continues to explore the flagship's systems, the Covenant AI aboard the ship temporarily gains control of the comms and alerts the local Covenant fleet to the ship's hijacking. Although Cortana is able to destroy the AI, her cover is blown, and she destroys a few enemy cruisers before fleeing into slipspace. 

Meanwhile, the humans find a canyon with some movement in it. The Chief wanders out to see if there is a trap, and Haverson backs him up. At the bottom of the ramp, Chief receives a signal without a [[Identification friend or foe|friend-or-foe tag]] (or IFF) indicating whom it belongs to, so he proceeds with caution. The Chief draws his pistol; only discover that it is [[Anton-044]], who disabled his IFF tag so the Covenant wouldn't discover his location. Anton leads the Master Chief to the entrance of a cavern, where two Spartans - [[Grace-093]] and [[Li-008]] - operate chainguns bolted to the sides of boulders. Master Chief and Anton, followed by Grace, enter the cavern. Inside, Admiral Whitcomb stands at a foldout card table: [[Camp Independence]].

Admiral Whitcomb questions why the Chief is here, instead of on [[Operation: RED FLAG|the mission]] with Captain Keyes deep inside Covenant territory. The Chief recounts a long story about [[Battle of Installation 04|the events]] that happened on Halo. Partway through, Haverson and the others arrive. Haverson asks Whitcomb how he is alive, and the Admiral tells Haverson that while everyone was evacuating, he stayed behind to help work on a new bomb called the [[NOVA Bomb|NOVA]], which possesses enough explosive force to destroy a planet. Whitcomb armed the NOVAs with fail-safe tampering detonators and a countdown timer. Whitcomb had a team of Marines - Charlie Company - help arm the NOVAs, but they were wiped out. He then "asked" on coded COM to borrow a few Spartans, who armed the NOVAs and had since given the Covenant trouble with hit-and-run attacks. The rest of Red Team remains trapped underground in the tunnels beneath the CASTLE facility.

Using the Covenant dropship, the Chief's group goes to rescue the remaining Red Team members. They enter a huge cavern filled with Covenant forces: a few Elites, Jackals, and mostly [[Unggoy|Grunts]] clearing a cave-in. They land the dropship half a kilometer away from the Covenant forces. After managing to destroy the Covenant, three Spartans - Kelly, Fred, and Will - emerge from cover. Whitcomb asks if there are any more, and Fred replies that there is one: Dr. Halsey, holding a fist-sized crystal. As they are about to leave, they detect more forces and become surrounded by thousands of Covenant - Grunts, Jackals, Elites and several pairs of [[Mgalekgolo|Hunters]] - on each of the gallery's twelve levels. A single Hunter pair fires their weapons at the humans; the rest of the Covenant opens fire a split second later.

Back in space, the ''Ascendant Justice'' emerges from slipspace in the system's [[Oort cloud]] to hide. Using the dissected Covenant AI, Cortana eavesdrops on the Covenant data streams, discovering that the Covenant is heading to Earth.

===Section 4: Gambit===
It is revealed that the Covenant forces weren't shooting at the group, but rather the Hunters, as they were under orders to take the crystal intact. Kelly takes two direct hits from the Hunters' plasma shots and is incapacitated. The Covenant then advances toward the group. Whitcomb signals for Polaski to pick them up and they leave just in time. However, while going up the gravity lift, the Covenant reverses it, pushing them back down. When Li opens the door to fire [[M19 SSM Rocket Launcher|Jackhammer]] rockets up the shaft, the crystal changes shape and disables the gravity lift. Once they exit the cavern, the crystal returns to normal.

On the ''Ascendant Justice'', Cortana uses [[Huragok|Engineers]] to combine the Covenant ship with another - the [[UNSC Gettysburg|UNSC ''Gettysburg'']] - to use its additional reactor power for maneuvering. She microjumps into slipspace and emerges at the rendezvous point, in the middle of the Covenant fleet. Chief and the survivors enter the ''Gettysburg-Ascendant Justice''. However, when Cortana jumps back into slipspace, the crystal causes them to enter an anomalous slipspace field with unusual properties, and the Covenant fleet follows. The fleet opens fire, but the plasma behaves erratically: doing loops, curving, and teleporting, etc. During the fight, Elites that survived the purge of the ''Ascendant Justice'' blow a small hole through its hull. The Spartans and Polaski go out to repair it, but encounter the Elites. As they fight, erratic plasma kills Polaski, Li, and Anton, and severely wounds Kelly. Desperate to escape, Cortana attempts to re-enter normal space. She succeeds, stranding the Covenant in slipspace and destroying them via sudden decompression of the anomalous slipspace field created by the crystal.

===Section 5: Massacre at Eridanus Secundus===
Recovering on the ''Gettysburg'', the Master Chief learns from Cortana that the Covenant has found Earth, and are preparing for a massive assault. Heading to the bridge, the Master Chief confers with Admiral Whitcomb and Lieutenant Haverson about their options. Their brief trip through the alternate dimension has placed them in the former [[Outer Colonies]]: long since destroyed by the Covenant, and with no nearby UNSC base to repair their ship. Additionally, the crystal emits an unknown radiation that will kill the crew in 72 hours. Learning that they are near the [[Eridanus system]], John informs Whitcomb that a former [[Insurrectionist]] [[Eridanus Secundus|base]] may still be active.

On the ''Gettysburg-Ascendant Justice'', Dr. Halsey tells the Chief that Linda will live. She then talks to him about Sergeant Johnson and his survival against the Flood. She reveals that Johnson has [[Boren's Syndrome]]: the only known defense against the Flood. Halsey gives John two data crystals containing information about the Flood: the first contains Dr. Halsey's analysis and a possible inoculation, and the second contains the source file of her conclusion, which would kill Johnson. She tells him to decide which one he wants to give to Haverson. After he leaves, Halsey and Cortana discuss the crystal and find that it can warp space, gravity, and even time. When Halsey and the Spartans found the crystal, it transported the Chief and the survivors back in time. Halsey realizes that neither the Covenant nor ONI [[ONI Section Three|Section Three]] may control the crystal. She erases Cortana's memory of her discussion with the Master Chief and analysis of the crystal.

For repairs, the group head to the system's asteroid belt, home of the rebel base [[Eridanus Secundus]]. During not-too-friendly negotiations with Governor [[Jacob Jiles]], a Covenant ship finds the group - due to the radiation the crystal emits upon exiting slipspace - and enters normal space. Despite malfunctioning plasma turrets, the crew of the ''Gettysburg-Ascendant Justice'' engages. When Cortana informs them that the magnetic coils used to shape the plasma aren't working, the Chief suggests using the ''Gettysburg'''s [[Magnetic Accelerator Cannon|MAC gun]] coils to shape it instead. During the fight, Halsey sedates Kelly and gives Locklear the crystal, ordering him to do whatever is necessary to ensure the Covenant does not retrieve it. She then steals an Insurrectionist stealth vessel and flees to [[Onyx|the location]] she discovered from Ackerson's logs on Reach. Locklear, devastated by the loss of his love, Polaski, takes the crystal down to a small bay and plants [[C-7 foaming explosive|C-7]] to destroy it. He blows the crystal up, accidentally killing himself in the process.

===Section 6: Operation: FIRST STRIKE===
{{main|Operation: FIRST STRIKE}}
{{Quote|Don't look like any '[[Unyielding Hierophant|uneven elephant]]' to me—more like two squids kissing. Whatever it is, damned glad it's going to blow up. Nice job—almost as good as if we sent in the Marines.|Sergeant Johnson}}

While the crew of the ''Gettysburg-Ascendant Justice'' is able to retrieve a few shards of the crystal, they have things that are more important on mind: the Covenant invasion of Earth. Cortana reveals that they are gathering at a battle station called the ''[[Unyielding Hierophant]]''. The Master Chief comes up with a plan: with help from a copy of Cortana's subroutines, he and the Spartans will go to the station in a modified dropship, infiltrate it, and blow up the reactors, delaying the launch of the fleet. Whitcomb agrees, but refuses to further risk ''Gettysburg-Ascendant Justice'', as they need to warn Earth about the Covenant fleet. 

John, Fred, Linda, Grace, and Will enter the station without incident, but are forced to detour through a temple complex. There, they encounter [[Jiralhanae|Brutes]]. The Master Chief grapples with one, barely making it out alive, and Grace is killed in the skirmish. After the fight, the Chief activates the fail-safe system in Grace's suit, killing many Covenant in the process. The four remaining Spartans make it to the reactors and rig them to explode. With ten minutes to escape, the Spartans commandeer three Banshees with the help of Linda's sniper fire. The Master Chief then rescues Linda from oncoming Covenant reinforcements.

After escaping the station, the Spartans steal a {{Pattern|Dextro Xur|Spirit}} and are surprised to receive the "Oly Oly Oxen Free" signal. Responding to the signal, the Spartans raise Admiral Whitcomb, who directs them to the other side of a nearby moon, explaining that he had taken ''Gettysburg-Ascendant Justice'' into the Oort cloud to do reconnaissance on the Covenant fleet, but realized from the size of it that even taking out the station and warning Earth would not be enough. 

On the other side of the moon, the Spartans find the ''Gettysburg'', but no sign of the ''Ascendant Justice''. On board, they learn that the crew removed the Covenant ship's slipspace engine and installed it in the ''Gettysburg''. Whitcomb and Haverson, who took the Covenant ship, crashed it into the central section of the ''Unyielding Hierophant''. Faking the crystal's appearance with a [[Holography|holograph]], they broadcast a message to the Covenant fleet in an attempt to lure them onto the ''Ascendant Justice''. When the ''Unyielding Hierophant'' reactors detonate, the explosion destroys the ''Ascendant Justice'' alongside almost five hundred ships of the Covenant invasion force, leaving a dozen left. The five human survivors - John-117, Fred-104, Linda-058, Will-043, and Sergeant Avery J. Johnson - and Cortana proceed to a random location under the Cole Protocol, and then return to Earth to warn them about the impending Covenant invasion.

===Section 7: Harbinger===
On ''[[High Charity]]'', [[Tartarus]] gives an orb containing shards of the Forerunner crystal to the [[Prophet of Truth|High Prophet of Truth]]. The Prophet orders Tartarus to reward the Covenant that recovered the shards and then execute them silently, and punish [[Thel 'Vadam|the commander]] for losing the ''Ascendant Justice''.

==2010 bonus content==
The Tor Books edition of ''First Strike'' features a new "Adjunct" section at the end, which includes several pieces of short fiction:
*A message from [[Charles VanKeerk]] to [[Amy]], where he offers his condolences regarding [[Sam (rebel)|Sam]]'s death, also reminding her of their still-ongoing [[Insurrection|fight]] against the UNSC.
*''[[Tug o' War]]'', a short story about [[Oliver Birch]], a [[Fetching|fetcher]] after the [[Human-Covenant War]].
*A transcript of a psychological debriefing of [[Frederic-104]] by Dr. [[Veronica Clayton]] during the [[Battle for Earth]].
*''[[Petra]]'', a short story about the reporter [[Petra Janecek]], where she speculates on the events surrounding the final days of the Human-Covenant War.

==Trivia==
*The original cover of the book had a graphic error on the Master Chief's head. The top part of his head was a little to the right of the bottom part, causing a split in his head. This was corrected in later versions.
*At the beginning of the novel, it is stated that twenty-seven Spartans were carried to the surface of Reach aboard ''Bravo 001''; however in ''Halo: The Fall of Reach'' it is stated that "two dozen Spartans" were present at Reach, in addition to the Master Chief, with three other Spartans (later revealed to be Gray Team) "engaged on fields of combat too distant to be easily recalled". Therefore, the Pelican that Fred-104 takes to the surface should only have twenty-two Spartans, (including Fred) since John-117 takes two Spartans with him in a separate Pelican for the mission to ''Gamma Station''. Several recent sources have definitively stated that twenty-two Spartans were assigned to Red Team, with the three-member Blue Team dispatched to ''Gamma Station'' and Gray Team behind enemy lines and thus out of contact.<ref>'''[[Data Drop]]'''</ref><ref>'''Halo Wars''' timeline</ref><ref>'''Halo: First Strike''' (2010) Adjunct)</ref><ref>[http://www.youtube.com/user/HaloWaypoint#p/a/DF8EE7CCE045CAA0/0/jh7Q3fjIIwc '''Halo Waypoint''' - ''Defiant to the End'']</ref><ref>'''[[Halo: Combat Evolved Anniversary]]''', [[Library (feature)|Library]] - Pelican</ref>
*In the original printing, the Longsword that John and the other survivors of the Battle of Installation 04 used to board ''Ascendant Justice'' is consistently referred to as a Pelican. This is corrected in the revised edition.
*One of the Spartans on the cover of the 2010 edition seems to be wearing [[MJOLNIR Powered Assault Armor/Mark IV|Mark IV]] armor, though no Spartans in Operation: FIRST STRIKE were equipped with Mark IV armor anymore. It is possible that this Spartan is simply wearing elements of the Mark IV with their Mark V armor.
*In the 2010 version, Brutes are no longer described as a never-before-seen Covenant species.
*In the 2010 adjunct section, Fred-104 is incorrectly referred to as a lieutenant during his psychological evaluation, which takes place during the early stages of the [[Battle for Earth]]. He actually held the rank of senior chief petty officer at this time and was not promoted to lieutenant, junior grade until the [[Onyx Conflict]].
*Prior to colliding in the launch bay of Ascendant Justice, the Longsword is going at a speed of 300&nbsp;m/s. This is equivalent to 1080&nbsp;km/h (671&nbsp;mph) and a sudden stop at that speed would kill the occupants immediately because of whiplash. A more reasonable speed would be 30&nbsp;m/s, equivalent to 108&nbsp;km/h (67&nbsp;mph) which, while still violent, would be survivable.<ref>'''Halo: First Strike''', ''Chapter 6''</ref>
