'''''Halo 4''''' is the seventh installment in the [[Halo universe|''Halo'' franchise]].{{Ref/Reuse|Xbox 360}}<ref name="waypoint">[https://www.halowaypoint.com/en-US/games/halo4 '''Halo Waypoint''': ''Halo 4'']</ref> Set four and a half years after the events of ''[[Halo 3]]'', ''Halo 4'' continues the story of [[John-117]] and [[Cortana]], left abandoned on the remains of the {{UNSCShip|Forward Unto Dawn}}. The two survivors drift toward the mysterious world of [[Requiem]] and the [[Ur-Didact|ancient evil]] within. ''Halo 4'' is the first game developed by [[343 Industries]], the management team in charge of the ''Halo'' franchise, and was published by [[Microsoft Studios]]. The first in a new series of ''Halo'' titles dubbed the [[Reclaimer Saga|''Reclaimer Trilogy'']], ''Halo 4'' was released exclusively on the [[Xbox 360]], worldwide on November 6, 2012.{{Ref/Reuse|Waypoint 4172012}}

''Halo 4'' was first revealed by a [[Awakening|teaser trailer]] shown at [[Microsoft]]'s [[Electronic Entertainment Expo|E3 Media Briefing]] on [[2011|June 6, 2011]], set to arrive in the holiday of 2012.<ref name="E3">[[wikipedia:Electronic Entertainment Expo|E3 2011]]</ref><ref>[http://halo.xbox.com/en-us/intel/related/video/halo-4-panel-opening-video/98674976-d76d-4c91-8048-084c9cf7982b '''Halo Waypoint''': ''Halo 4 Panel Opening Video'']</ref><ref name="h4panel">[http://www.youtube.com/watch?v=JD429ZWcQ_w '''YouTube''': ''Halo Fest: Halo 4 Panel'']</ref> In the months leading into [[Wikipedia:Electronic Entertainment Expo 2012|E3 2012]], multiplayer for ''Halo 4'' would be unveiled. The game would then get proper coverage during [[Wikipedia:Electronic Entertainment Expo 2012|E3 2012]], where a [[Halo 4 E3 2012 Stage Demo|stage demo]] would be shown off, along with a trailer dubbed "''[[The Commissioning]]''", and the game's new co-operative experience, ''[[Spartan Ops]]''. 

Upon the first day of release, ''Halo 4'' grossed $220 million, surpassing ''[[Halo: Reach]]'''s record of $200 million, and $300 million in its opening week.

Along with ''[[Halo: Combat Evolved Anniversary]]'', ''[[Halo 2: Anniversary]]'' and ''Halo 3'', ''Halo 4'' was released on the [[Xbox One]] as part of ''[[Halo: The Master Chief Collection]]'' on November 11, [[2014]]. A sequel, ''[[Halo 5: Guardians]]'', was released for the [[Xbox One]] on October 27, [[2015]].<ref name="H5">[http://news.xbox.com/2014/05/games-halo-journey-announcement '''Xbox Wire''': ''The Halo Journey'']</ref>

The story of ''Halo 4'' was described as being heavily focused on mystery, exploration and discovery, as well as being grand in scope and scale. Forerunner elements are featured extensively. The game also shows how humanity and the UNSC have adapted to the post-war world, particularly how they have co-opted Forerunner technology into their military devices and assets.{{Ref/Reuse|h4panel}} Member species of the former [[Covenant]] return  in the game, in the form of [[Jul 'Mdama's Covenant faction]], consisting of [[Sangheili|Elites]] and most of their former subordinate species, including [[Unggoy|Grunts]] and [[Kig-Yar|Jackals]], still loyal to the tenets of the [[Covenant religion]].<ref name="bulletin1">[http://halo.xbox.com/blogs/Headlines/post/2012/03/08/The-Halo-Bulletin-30712.aspx '''Halo Official Site''': ''The Halo Bulletin: 3.07.12'']</ref>{{Ref/Reuse|Game Informer May 2012}} However, the Covenant remnants are taking a backseat to an entirely new antagonist, the [[Promethean]]s,<ref name="press center">[http://press.xbox360.com/products/p51/halo-4?grp=Blockbuster+Games&event=5 '''Xbox.com''': ''Xbox Press Center - Halo 4'']</ref> an elite class of [[Forerunner]] [[Warrior-Servant|Warriors]] and their legendary leader known as the [[Ur-Didact|Didact]];<ref name="gttv promo">[http://www.gametrailers.com/videos/t3eqhy/gt-tv-gttv-halo-4-promo '''GameTrailers''': ''GTTV Halo 4 Promo'']</ref> this new antagonist has been described as a "threat beyond anything that Master Chief has faced before."<ref name="venture">[http://venturebeat.com/2012/03/05/11-things-learned-about-halo-4/ '''Venturebeat.com''': ''11 new things we’ve learned about Halo 4 (with video)'']</ref> The subject of Cortana's ongoing [[rampancy]], a year beyond her ideal functional lifespan, is also thoroughly and prominently detailed in ''Halo 4''.<ref name="HW Characters">[http://halo.xbox.com/halo4#!an-epic-universe/characters/8c164b48-05e7-4c13-a268-f60ec3a72938 '''Halo 4 Official Site:''' ''CHARACTERS'']</ref>

Unlike ''[[Halo: Combat Evolved]]'', ''Halo 4'' was originally stated to have been designed to be part of a three-game arc from the beginning; however, the scope of the then-''Reclaimer Trilogy'' (now known as the ''Reclaimer Saga'') has since been expanded to encompass an undefined number of games.<ref name="Saga">[http://www.ign.com/articles/2013/06/21/halo-reclaimer-trilogy-expanded-to-saga '''IGN''': ''Halo Reclaimer Trilogy Expanded to <nowiki>'Saga'</nowiki>'']</ref> In addition, 343 Industries is aiming for more complete connectivity among all of their future media than that of the original trilogy;{{Ref/Reuse|h4panel}} the ''[[The Forerunner Saga|Forerunner Saga]]'' and ''[[Kilo-Five Trilogy]]'' novels,{{Ref/Reuse|bulletin1}}<ref>[http://halo.xbox.com/Content/assets/en-us/Podcast/343Sparkast_005.mp3 '''Halo Waypoint''' - ''343 Sparkcast 005'']</ref> and the ''Halo: Combat Evolved Anniversary'' [[Terminal (Halo: Combat Evolved Anniversary)|terminals]] all have connections to ''Halo 4'''s story.{{Ref/Reuse|h4panel}}<ref>[http://www.youtube.com/watch?v=TNDQN7nwZlw&feature=related '''YouTube''': ''SDCC 2011: Halo Universe Panel Part 1'']</ref> The third and final ''Forerunner Saga'' novel, [[Halo: Silentium|''Silentium'']], was released on March 19th, 2013.<ref name="Greg Bear Forum 532012">[http://www.gregbear.com/blog/display.cfm?id=6420 '''Greg Bear - Discussion Board''': ''Book'']</ref><ref name="Greg Bear Forum 542012">[http://www.gregbear.com/blog/display.cfm?id=6462 '''Greg Bear - Discussion Board''': ''PRIMORDIAL GRAVEMIND'']</ref><ref name="Silentium 7112012">[http://halo.xbox.com/blogs/Headlines/post/2012/07/11/Tor-Books-Reveals-Title-Cover-Art-And-Release-Date-of-Third-Halo-Novel-By-Greg-Bear.aspx '''Halo Waypoint:''' ''Tor Books Reveals Title, Cover Art, And Release Date of Third Halo Novel By Greg Bear'']</ref> Frank O'Connor noted that ''Silentium'' would be released after ''Halo 4'' for "specific strategic reasons", likely referring to the connectivity of the game and the novel.<ref name="Bulletin 372012">[http://halo.xbox.com/blogs/Headlines/post/2012/03/08/The-Halo-Bulletin-30712.aspx '''Halo Waypoint''': ''The Halo Bulletin: 3.07.12'']</ref> A live action series, ''[[Halo 4: Forward Unto Dawn]]'', provides a backstory for [[Thomas Lasky]], a major character in the game; this series consists of five episodes totaling 75 minutes.

{{Spoiler/begin}}
===Discovery===
[[File:H4fudback.jpg|thumb|250px|The wreckage of the ''Forward Unto Dawn'' floating in space.]]
Halo 4 begins on [[2557|July 21, 2557]],<ref name="Game Informer May 2012">'''Game Informer''': ''May 2012''</ref> four years, seven months and ten days after the armistice ending the [[Human-Covenant War]]. Cortana, laying silent for almost five years, notices that the ship's intruder alarms have activated and attempts to wake John-117 from [[Cryo chamber|cryo-sleep]]. Cortana notifies him that in his sleep, she rewrote the firmware of his [[MJOLNIR Powered Assault Armor/Mark VI|MJOLNIR Mark VI armor]], upgrading the HUD and armor capabilities. With alarms ringing and the intruders spreading to multiple decks, John slips Cortana's chip back into his [[Spartan neural interface|neural interface]] and sets off to find the source of the disturbance. Suddenly, a [[Sangheili]] swordsman comes charging at the Spartan. After neutralizing the threat, John questions the AI construct on why his once-formidable allies have attacked them, to which she has no answer. After fighting the Sangheili and their "repatriated" [[Unggoy]] and [[Kig-Yar]] subordinates, John makes his way to the aft observation deck, viewing a large [[Jul 'Mdama's Covenant|former Covenant]] fleet, led by [[Jul 'Mdama]], surrounding the ''Forward Unto Dawn'' while multiple boarding crafts dock with the heavily damaged aft section of the frigate. 

John and Cortana subsequently make a crash-landing on the Forerunner world [[Requiem]], entering the inner planetary shell via an entrance in the [[Dyson sphere]]-like superstructure.{{Ref/Reuse|Game Informer May 2012}} Recovering a [[M12 Light Reconnaissance Vehicle|Warthog]], Master Chief and Cortana vow to make their way back to Earth in order to find a cure for Cortana's escalating Rampancy. They set out to find a way to contact the UNSC, circumventing the powerful jamming field surrounding the world.

Fighting through numerous Jul 'Mdama's Covenant hunting parties, Master Chief is attacked by advanced Forerunner combat constructs which Cortana identifies as Prometheans. Evading or destroying pursuit, John attempts to warn the approaching {{UNSCShip|Infinity}} of the dangerous artificially-induced gravity field that had caused the ''Forward Unto Dawn'' to crash.

===The Didact===
[[File:H4 John-117 Didact first encounter.jpg|thumb|250px|John-117 encounters the Didact.]]
After disabling two control nodes, it becomes clear to John that a great threat had once been imprisoned within Requiem. The [[Ur-Didact|Didact]], the Forerunners' greatest warrior, is released from suspended animation within a [[Cryptum]]. Easily disabling John with his powerful abilities, he declares the return of the Forerunners as the galaxy's rulers and saviors. Humanity remains weak and unworthy in his eyes of inheriting the [[Mantle|Mantle of Responsibility]], a view rejected by his wife, the [[Librarian]]. Having always revered the Forerunners as gods,Jul 'Mdama's Covenant quickly swears alliance to the Didact and his Prometheans. The Didact views Jul's Covenant as mere "primitives", but permits them to serve his cause, to prevent the ascension of the human race to galactic prominence.

Narrowly escaping the collapsing core facility, the Chief and Cortana return to the planet's surface only to find their warning to the ''Infinity'' came too late. The warship crashes more than 70 kilometers away, with a massive force of Jul 'Mdama's Covenant and Prometheans closing on their position.

Evading capture, John is successful in regrouping with a group of [[SPARTAN-IV Program|SPARTAN-IVs]] and Marines led by [[Commander]] [[Thomas Lasky]]. Recognizing the Chief immediately, Lasky asks John and Cortana to clear a landing zone so that ''Infinity'''s ground forces can fall back to the ship which has fallen under siege. Commandeering a Scorpion tank, John leads the attack to the crippled vessel alongside Commander [[Sarah Palmer]]'s Spartans. Using the UNSC's latest weapon, the [[HRUNTING/YGGDRASIL Mark IX Armor Defense System|Mantis]] exoskeleton, John rallies a force of nearby Marines and regains control of the ship's interior. After reinitializing the secondary MAC guns and missile batteries, the tide turns in the UNSC's favor. Two light cruisers and dozens of dropships are destroyed in the artillery barrage, while the Didact's Cryptum is forced to retreat.

With a momentary lull in the fighting, John is called to a strategy meeting with [[Andrew Del Rio]], Captain of the ''Infinity''. Skeptical of the threat of the Prometheans, Rio orders an immediate attack on a Forerunner gravity well generator preventing the ship from leaving. A strike force of Spartans led by John is deployed along with a [[Mobile Anti-Aircraft Weapons Platform M510 Siegework/Ultra-Heavy|Mammoth]] ultra-heavy ground vehicle supporting the attack. Facing daunting odds, the UNSC is able to defeat a large armored strike force of Jul 'Mdama's Covenant and Prometheans and they disable the gravity beam. Before reaching his objective, John is confronted with a vision from the deceased [[Librarian]], who warns him of the Didact's true plans.

===The Composer===
[[File:H4 John-117 and Librarian.PNG|thumb|250px|John-117 meets the essence of the Librarian.]]
In ancient times, the human race was once a [[Prehistoric human civilization|great interstellar empire]]. Fleeing from the [[Flood]] and [[Human-Flood war|destroying]] any world tainted with their presence, they came into contact with the Forerunner [[ecumene]]. Ignoring their warnings about the dangers posed by the parasite, the Forerunner [[Warrior-Servant|warrior]]s led by the Didact [[Human-Forerunner War|defeated]] and imprisoned humanity upon their homeworld. Weakened by the struggle, the Forerunners [[Forerunner-Flood war|were easy prey]] for the resurgent Flood. Defying the Forerunners' decision to accept the [[Halo Array]] as their final resort, the Didact used a device known as the [[Composer]], capable of transferring organic consciousness to software format, to convert his warriors into mechanical Promethean Knights, in order to combat the Flood (which could only infect living tissue) more effectively and without risk of infection. Lacking the sufficient numbers to turn the tide, the Didact used the Composer to "conscript" a large population of humans into his army, leading to the confiscation of the Composer and his imprisonment on Requiem. Opposing the Didact for her own reasons, the Librarian provides John with a gift: a medical treatment to counteract the Forerunner's devolution of the human genome, and a means to resist the effects of the Composer, with which the Didact plans to enslave the human race once again.

Regrouping aboard the ''Infinity'', Captain Del Rio dismisses the threat of the Prometheans and prepares the ship to depart the system. Defying direct orders, John takes the increasingly unstable Cortana and departs the ''Infinity''. Armed with a [[D79-TC Pelican|Pelican]] gunship provided by Commander Lasky, John launches several attacks on support pillars providing the Didact's Cryptum with shields and power, with the goal of preventing him from leaving the planet and attacking Earth.

[[File:H4-ComposerFiringOnPhoenix.jpg|thumb|left|250px|The Composer fires on New Phoenix.]]
This attempt ultimately proves unsuccessful, as the Didact leaves Requiem aboard his massive vessel, the ''[[Mantle's Approach]]'', escorted by a flotilla of Jul 'Mdama's Covenant ships. Stowing away aboard a [[Lich]], Master Chief pursues the Forerunner to [[Ivanoff Station]], a UNSC research base orbiting Halo [[Installation 03]] where the Composer is kept. Dr. [[Sandra Tillson]], a lead researcher aboard the base, helps guide John to the artifact amidst a swarm of Jul's Covenant attackers. Despite reaching the artifact first, the Didact is successful in obtaining the Composer, tearing it out of the station's hull with a gravity beam. Testing the weapon, the Composer burns the crew of the station to ash, harvesting their essences to power additional Prometheans. The Master Chief survives, thanks to the genetic enhancements provided by the Librarian.

With the Composer in the Didact's possession, the Forerunner is poised to deal a deathblow to the UNSC, and by extension humanity. Racing back to Earth aboard a [[F-41 Broadsword|Broadsword]] fighter stowed on the outer hull of the Didact's ship, the Master Chief finds the ''Infinity'' and a [[Battlegroup Dakota|UNSC battlegroup]] waiting for him. Flying below the Forerunner vessel's shields, John is able to destroy the ship's point defense guns, allowing ''Infinity'' to bombard its hull. Entering through a breach in the armor, John fights his way to the Didact's location.

Despite their best efforts, the Didact is able to fire the Composer at Earth, North America. Armed with a [[HAVOK tactical nuclear weapon|HAVOK portable nuclear device]], John confronts the Didact once again. While John is no match for the Forerunner's powerful abilities, Cortana, nearing the end of her life, immobilizes the Didact with [[hard light]] shackles. With the last of his strength, John defeats the Didact with a [[Z-040 Attenuation Field Generator/Localized|pulse grenade]], sending him falling into a slipspace rupture beneath the Composer, and detonates the nuclear bomb manually.

===Farewells===
[[File:John and Cortana re-unite - Close shot.png|thumb|250px|The Master Chief and Cortana meet for the last time.]]
With the last of her power, Cortana is able to [[Slipspace translocation|teleport]] John away from the vessel before it was destroyed and meets with John for one last time inside a bubble of hard light. Overcome with emotion, John remarks that he was supposed to have protected her. Cortana insists that they were supposed to protect each other, and did. Using her hard light body, Cortana is able to actually touch John for the first time, which she says that she's been waiting to do for a very long time. Smiling and seeming at peace, Cortana welcomes John home, and then fades away completely. The Master Chief drifts in space amidst the debris of the Didact's ship for a time before being recovered by a UNSC search-and-rescue team. Later, John speaks with (now Captain) Lasky about the loss of his closest friend and companion.

In the battle's aftermath, a UNSC team investigates the city of [[New Phoenix]], where the [[Composer]]'s energy beam was directed; although the infrastructure of vehicles and buildings are completely untouched, its former human inhabitants are gone. Aboard the ''Infinity'', John rejoins Palmer and the other Spartans, preparing for their inevitable next battle, and his MJOLNIR Mark VI armor is removed for the first time in years. The final scene is overlaid with a speech given by the Didact to his fellow Forerunners, after being accused of attempting to wipe out human life. In this speech, the Didact maintains his belief that only the Forerunners are worthy of the Mantle and that humanity should never be allowed to reclaim the Forerunners' accomplishments.

While their defeat at Earth proved a setback for the Didact's Prometheans and Jul 'Mdama's Covenant, it did not result in their defeat. Months later, the Infinity returns to Requiem with a complement of Spartans, determined to claim the planet. This tour forms the background for the [[Requiem Campaign]] covered in the ''[[Spartan Ops]]'' mode.

==Development==
===Gameplay and design===
[[File:Selecting ordnance - damage boost.png|thumb|A first-person view of ''Halo 4'''s multiplayer.]]
''Halo 4'' was developed for the Xbox 360 console.{{Ref/Reuse|Xbox 360}} The game's creative team, which comprised nearly 200 individuals who developed the game for nearly three years,<ref name="GTTV 612012">[http://www.gametrailers.com/video/e3-2012-e3-2012/730801 '''GameTrailers.com:''' ''E3 2012: Halo 4 Xbox Evolved Promo'']</ref> was led by creative director [[Josh Holmes]].{{Ref/Reuse|h4panel}} The game has been stated to continue the ''Halo'' series' tradition of inspiring wonder in the player while providing engaging, visceral gameplay. The game utilizes much of the "sandbox" that has been featured across all six prior ''Halo'' games and other media, in addition to introducing new characters, weapons, vehicles, and other elements.{{Ref/Reuse|h4panel}} The game's "sandbox" and overall style are meant to be evocative of ''Halo: Combat Evolved'' moreso than of later installments.{{Ref/Reuse|CVG}} [[Dual wielding]] is not accessible in the game.<ref name="GI podcast">[http://media1.gameinformer.com/media/audio/theshow/halo4/halo4special.mp3 '''Game Informer:''' ''Halo 4 Special Podcast'']</ref> During production, Halo 4 was given the codename "Halo Onyx".<ref>[https://www.artstation.com/artwork/Brwkm '''Artstation:''' ''Halo 4 - vehicles'' - concept art bears the logo "Halo Onyx".]</ref>

The narrative design team of ''Halo 4'' was headed by [[Armando Troisi]], who previously worked on [[Wikipedia:Mass Effect|''Mass Effect'']] and its [[Wikipedia:Mass Effect 2|sequel]], along with an in-house team of writers. The original draft of the ''Halo 4'' script was written by [[Chris Schlerf]], who has also had major influence on the script since then. [[Brian Reed]], who wrote the 2010-2012 graphic novel adaptation ''[[Halo: Fall of Reach]]'', was also part of the writing team and made significant contributions on the story.<ref>[http://carnage.bungie.org/haloforum/halo.forum.pl?read=1137839 '''halo.bungie.org''': ''Re: Who's the writer for Halo 4?'']</ref>

The art director for ''Halo 4'' was [[Kenneth Scott]]. He described the visual style of ''Halo 4'' as being more ingrained in the expanded universe fiction, and more "mature" than before. With the game's increased focus on the Forerunners, the artists invested heavily on the look and feel of Forerunner technology, including the incorporation of more "active" Forerunner technology as opposed to the mostly inert and abandoned structures seen in the earlier games.{{Ref/Reuse|h4panel}}

John-117's experience and the player's experience are meant to be intertwined, with the Master Chief essentially serving as the player's avatar within the ''Halo'' universe. John's character is explored and developed in more depth than in the prior games, and the relationship between John and Cortana is heavily featured and expanded. ''Halo 4'' also features more athleticism, as the background of Master Chief and the Spartan supersoldiers in general promise a feeling of "a super hero", a feeling 343 Industries wanted to convey to the player.{{Ref/Reuse|h4panel}}

As with many other art assets, the ''Halo 4'' art team redesigned the Master Chief's iconic MJOLNIR armor from the ground up. The first look into the redefined armor, which differs considerably from the suit seen in ''Halo 3'', was seen in the announcement trailer, generating a considerable amount of confusion and speculation among fans. 343 Industries later stated that the design seen in the trailer was not the final version.{{Ref/Reuse|h4panel}} The final iteration was later seen alongside the first ''Halo 4'' gameplay reveal following Microsoft Spring Showcase 2012. The changes in the design are mostly cosmetic and were made with the intent of giving the suit a more functional look in order to suit the new art direction of the game.<ref name="first look">[http://www.youtube.com/watch?v=f6UL63Zo-uo&feature=player_embedded '''YouTube''': ''Making Halo 4: First Look'']</ref> In a fictional context, the difference in the suit's appearance is explained by an extensive overhaul performed by Cortana while John was in cryo-sleep.{{Ref/Reuse|Game Informer May 2012}}<ref name="Official Site">[http://halo.xbox.com/halo4#!halo-evolved/gameplay/31afe32b-0e07-45c0-9424-3adc6e1eadca '''Halo 4 Official Site:''' ''GAMEPLAY'']</ref>

[[Wikipedia:Motion capture|Motion capture]], first implemented in the series on ''[[Halo: Reach]]'', was used during the production of ''Halo 4''.<ref name="Bulletin 592012">[http://halo.xbox.com/blogs/Headlines/post/2012/05/09/The-Halo-Bulletin-5912.aspx '''Halo Waypoint:''' ''The Halo Bulletin: 5.9.2012'']</ref> Recording began prior to the release of the ''Making Halo 4: First Look'' video in [[Wikipedia:Los Angeles|Los Angeles]], [[Wikipedia:California|California]], with material for the character Cortana and a man playing an unidentified character filmed; recordings were done as recently as the week of April 29, 2012.{{Ref/Reuse|Bulletin 592012}} [[Bruce Thomas]] and Mackenzie Mason would later be confirmed as the cinematic performance capture actors for John-117 and Cortana, respectively.{{Ref/Reuse|Bulletin 692012}}

While most cutscenes in the game are rendered in real-time in the game engine, ''Halo 4'' is the second game in the series (along with ''[[Halo Wars]]'') to use pre-rendered cinematics. Except for ''Spartan Ops'', three scenes from the game (along with the introduction of the ''Infinity'' mode) were computer animation produced by Digic Pictures<ref>[http://www.digicpictures.com/ '''Digic Pictures''']</ref> and one scene produced by [[Sequence]].<ref>[http://thesequencegroup.com/work/2/halo-4 '''The Sequence Group''']</ref>

At a London press event for ''Halo 4'', it was announced that development of the game was completed on September 25, 2012 after three years in development.<ref name="VG 92612">[http://www.videogamer.com/xbox360/halo_4/news/halo_4_development_is_complete.html '''VideoGamer.com —''' ''Halo 4 development is complete'']</ref> The finished product was then sent to "various certification processes" before mass production of the game began. Coincidentally, the September 25 completion date of ''Halo 4'' also marks the fifth anniversary of the North American release of its predecessor, ''Halo 3''.

===Audio===
[[Sotaro Tojima]], best known for his work on [[Wikipedia:Konami|Konami's]] ''[[Wikipedia:Castlevania: Circle of the Moon|Castlevania: Circle of the Moon]]'' and ''[[Wikipedia: Metal Gear Solid 4: Guns of the Patriots|Metal Gear Solid 4: Guns of the Patriots]]'', served as ''Halo 4'''s audio director.{{Ref/Reuse|h4panel}} The team has performed many live audio recording sessions, several of which occurred in [[Wikipedia:Tasmania|Tasmania, Australia]]. Some of these recording sessions took place in generally inhospitable environments, such as underwater, in fire, and in ice, through the use of specially designed microphones;{{Ref/Reuse|h4panel}} other recording sessions utilized "homemade" explosives.<ref name="Audio">[http://www.youtube.com/watch?feature=player_embedded&v=Lci6hIWxZss'''Halo Waypoint''': ''Halo 4 Field Audio Recording'']</ref> Tojima intended for the game's audio to be clearly grounded in the ''Halo'' universe, though to also have a more realistic quality than in past titles.{{Ref/Reuse|h4panel}} A video was released on February 23rd depicting 343i recording weapon and explosion audio alongside the [[Wikipedia:United States Army Special Forces|U.S. Army Special Forces]]. Weapons such as the [[Wikipedia:M4 carbine|M4 carbine]], [[Wikipedia:FN SCAR|Mk 17 battle rifle]], [[Wikipedia:M240 machine gun|M240 general purpose machine gun]], [[Wikipedia:Barrett M82|M107 sniper rifle]], [[Wikipedia:M2 Browning|M2 heavy machine gun]], and [[Wikipedia:M72 LAW|M72 rocket launcher]] were used in the recording.{{Ref/Reuse|Audio}}

Several voice actors from previous media reprised their roles in the game. [[Jen Taylor]], voicing the AI Cortana, and [[Jeff Steitzer]], the multiplayer and firefight [[The announcer|announcer]], confirmed on Facebook that they would again be reprising their roles for ''Halo 4''.<ref>[http://halo.bungie.org/images/taylors_back.png '''Facebook.com''' and '''Halo.Bungie.org''': ''Jeff Steitzer announcement on voice acting'']</ref> [[Steve Downes]], the iconic voice of John-117, was confirmed to voice the game's protagonist in the June 9th Halo Bulletin.<ref name="Bulletin 692012">[http://halo.xbox.com/blogs/Headlines/post/2012/06/09/The-Halo-Bulletin-6912.aspx '''Halo Waypoint:''' ''The Halo Bulletin 6.9.2012'']</ref> For the first time in the ''Halo'' series, Taylor and Downes recorded the dialog for some of their scenes together in the same voicing booth, whereas previously they had not even met in person.<ref>[https://www.youtube.com/watch?v=sR2cwas3BXY '''YouTube''': ''Interview: Steve Downes and Tim Dadabo (Master Chief and 343 Guilty Spark) at Dragon Con 2014'']</ref> On the April 17th, 2012 episode of the [[Wikipedia:TBS (TV channel)|TBS]] late night comedy show [[Wikipedia:Conan (TV series)|''Conan'']], hosts [[Wikipedia:Conan O'Brien|Conan O'Brien]] and [[Wikipedia:Andy Richter|Andy Richter]] announced that they'll be voicing Navy deckhands aboard the advanced warship ''Infinity''.<ref name="Conan 4172012">[http://www.youtube.com/watch?feature=player_embedded&v=GflJB-aM0wI '''Conan''': ''Episode 245 - April 17, 2012'']</ref> Frank O'Connor, replying to a fan's question at the Rooster Teeth Expo, stated that the cast for the episodic cooperative series ''Spartan Ops'' would have the "biggest injection" of new voice talent for ''Halo 4''.<ref name="RTX Halo 4 panel">[http://www.youtube.com/watch?v=lnHPPsQFovY&hd=1 '''Rooster Teeth Expo:''' ''Halo 4 presentation'']</ref>

On April 11, 2012, the composer for ''Halo 4'' was announced to be [[Neil Davidge]], best known as the co-writer and producer for the British electronica duo [[Wikipedia:Massive Attack|Massive Attack]].<ref>[http://halo.xbox.com/blogs/Headlines/post/2012/04/11/Neil-Davidge.aspx '''Halo Official Site''': ''The Halo Bulletin: 4.11.12'']</ref> Davidge first started in his role as the future composer in late 2010, eventually having his first meeting with 343i laying out his ideas for the music of the game.<ref name="Edge 582012">[http://www.edge-online.com/features/scoring-halo-4?page=2 '''Edge Magazine:''' ''Scoring Halo 4'']</ref> After the meeting, Davidge began writing 20 to 30 pieces that would be the base of the ''Halo 4'' score, which he officially began working on in August of 2011. Davidge has since stated that over four hours and an estimated 300 pieces had been written as of May 8, 2012.{{Ref/Reuse|Edge 582012}} Composing ''Halo 4'' is noted as being split into four distinct "tiers," each consisting of central themes for a handful of missions. [[Kazuma Jinnouchi]] composed a number of additional tracks for the game.<ref>[http://www.halo4soundtrack.com/ '''Halo4soundtrack.com''']</ref> Many of the key compositions were recorded and completed in January 2012 ahead of 343i's completion deadline.{{Ref/Reuse|Edge 582012}} Though still grounded in the ''Halo'' universe, the score for ''Halo 4'' takes a new direction from [[Martin O'Donnell]]'s composition in previous ''Halo'' titles.{{Ref/Reuse|bulletin1}} Orchestral and composition for the score was done at the famed [[Wikipedia:Abbey Road Studios|Abbey Road Studios]] in [[Wikipedia:City of Westminster|Westminster]], [[Wikipedia:London|London]], [[Wikipedia:England|England]], mostly notably known for their work with [[Wikipedia:The Beatles|The Beatles]] during the 1960s.<ref name="Composing Worlds">[http://www.youtube.com/watch?v=ZmfGsuOacMA&hd=1 '''YouTube:''' ''Making of Halo 4: Composing Worlds'']</ref>

==Multiplayer==
[[File:H4-Ordnance Overshield.jpg|thumb|An Overshield power-up drop.]]
The competitive and cooperative multiplayer modes of ''Halo 4'' are grouped together into a mode known as ''Infinity'', which is tied to the ''Halo'' series fiction and runs parallel to the campaign story. In ''Infinity'', players take control of [[SPARTAN-IV Program|SPARTAN-IV supersoldiers]] serving aboard the advanced warship, UNSC ''Infinity''.<ref name="mp1">[http://www.digitalspy.co.uk/gaming/interviews/a369211/halo-4-interview-343-industries-on-multiplayer-new-forms-of-story.html '''Digitalspy.co.uk''': ''Halo 4 interview: 343 Industries on multiplayer, new forms of story'']</ref> Prior to the beginning of development on ''Halo 4'', 343i General Manager [[Bonnie Ross]] and Frank O'Connor set the framework of the new studio's mission which entailed that all pieces of existing and future fiction from the games, novels, comics, etc. would be interwoven and share content from each other.<ref name="Guardian 632012">[http://www.guardian.co.uk/technology/gamesblog/2012/jun/04/e3-2012-halo-4-interview '''The Guardian:''' ''E3 2012: Frank O'Connor on Halo 4 – Spartan Ops could run for years'']</ref> Among this would be the multiplayer component for ''Halo 4'', which would later include the introduction of ''Spartan Ops''; "'' Wrapping the whole thing together allowed us to make sure that all the fiction in all of those pieces actually mattered – in this case, it connects directly to your career as well as the narrative experience.''"{{Ref/Reuse|Guardian 632012}}

=== War Games ===
{{Main|War Games}}
Competitive multiplayer, known as "''War Games''," pits players against one another in adversarial combat training in simulated environments in the advanced combat deck of the ''Infinity''.{{Ref/Reuse|first look}}{{Ref/Reuse|mp1}} However, due to the emphasis on the SPARTAN-IV commandos, players do not have the option to use [[Sangheili]] for their multiplayer character.<ref name="IGN 4/7/2012">[http://xbox360.ign.com/articles/122/1222537p1.html?utm_campaign=ign+main+twitter&utm_source=twitter&utm_medium=social '''IGN.com''': ''Spartan Ops and Infinity Change Halo 4 Multiplayer'']</ref>

343 Industries aimed to provide a "brand new experience" in ''Halo 4'' multiplayer. This includes a reworking of the series' traditional balance system. For example, the player progression system is more extensive, allowing players to choose between various modifications which have an effect on gameplay, in addition to aesthetic [[armor permutations]] similar to the prior games.{{Ref/Reuse|venture}}{{Ref/Reuse|Official Site}}<ref name="cod">[http://www.guardian.co.uk/technology/gamesblog/2012/mar/05/halo-4-multiplayer-details-revealed '''Guardian.co.uk''': ''Halo 4 multiplayer revealed: Master Chief meets Call of Duty?'']</ref> Players are able to customize their [[loadout]]s,<ref>[http://www.gamefront.com/halo-4-demo-report/2/ '''Gamefront.com''': ''Halo 4 Demo Report'']</ref> being able to choose between various [[armor abilities]] as well as new customizable features, known as [[Support Upgrades]] and [[Tactical Packages]]. Tactical Packages offer a small performance boost to a chosen gameplay feature, such as the player's shield or weapon carrying capacity. Support Upgrades function similarly, and feature such improvements as [[motion tracker]] upgrade and an increase in the player's maximum ammunition.{{Ref/Reuse|Official Site}} ''Halo 4'' also introduces a new gameplay enhancement feature referred to as "[[Specializations]]". Specializations unlock different armor sets, emblems, visor colors, weapon and armor skins, and armor mods, which work similar to tactical packages and support upgrades.<ref name="The Halo Bulletin: 8.15.12">[http://halo.xbox.com/blogs/Headlines/post/2012/08/15/The-Halo-Bulletin-81512.aspx '''Halo Waypoint''' ''The Halo Bulletin 8.15.12]</ref>

343 Industries has described ''Halo 4'''s multiplayer gameplay as "much more fast-paced, more intense and visceral" than in the prior games.{{Ref/Reuse|cod}} Weapon pickups on maps are marked on the player's [[heads-up display]],{{Ref/Reuse|venture}} and players are able to call in ordnance drops, containing power-ups or weapons, during War Games or Spartan Ops matches.{{Ref/Reuse|Official Site}} Some multiplayer gametypes include [[Slayer]], Infinity Slayer, and [[Regicide]]. Power-ups available in Infinity Slayer include [[Overshield]], [[Damage Boost]], and [[Speed Boost]].<ref>[http://halo.xbox.com/blogs/Headlines/post/2012/07/06/The-Halo-Bulletin-7612.aspx '''Halo Waypoint''': ''The Halo Bulletin: 7.6.12'']</ref>

==== List of multiplayer maps ====
Unlike ''[[Halo: Reach]]'', where the original multiplayer maps were shared in the campaign as gameplay spaces, all multiplayer maps in ''Halo 4'' were purpose-built for multiplayer alone much like in the first three ''Halo'' games{{Ref/Reuse|cod}} (although some multiplayer maps are featured in Spartan Ops). 343 Industries collaborated with [[Certain Affinity]] in the production of the multiplayer maps for ''Halo 4''.<ref name="Certain Affinity">[http://www.oxmonline.com/343-industries-halo-4-will-re-inject-some-new-life-halo-multiplayer '''Official Xbox Magazine online.com''' ''343 Industries: Halo 4 will "re-inject some new life" into Halo multiplayer]''</ref><ref name="gsforge">[http://www.gamespot.com/halo-4/videos/exclusive-halo-4-forge-mode-details-6397629/ '''GameSpot''': ''Exclusive Halo 4 Forge Mode Details'']</ref>

====Armor permutations====

{{Main|Spartan Ops}}
''Spartan Ops'' is a secondary campaign that replaces the [[Firefight]] mode featured in ''[[Halo 3: ODST]]'' and ''[[Halo: Reach]]''.{{Ref/Reuse|IGN 4/7/2012}} Much like traditional campaign cooperative play, ''Spartan Ops'' allows up to four players to participate in weekly objective-based episodic missions.{{Ref/Reuse|GI podcast}}{{Ref/Reuse|IGN 4/7/2012}} Missions intertwine directly with events in the main ''Halo 4'' campaign, expanding on the story of the UNSC ''Infinity'' and her crew;{{Ref/Reuse|GI podcast}} this new mode is being likened to a second full-scale campaign for the game.{{Ref/Reuse|Guardian 632012}} Compared to a season of a television program, each "episode" of ''Spartan Ops'' features a pre-rendered cinematic and five playable missions complete with new events, characters, locations, and gameplay challenges, totaling up to 12 hours of new gameplay.{{Ref/Reuse|Game Informer May 2012}}<ref name="LEHB 6272012">[http://www.littleenglishhaloblog.com/2012/06/new-halo-4-info-blowout-via-expertzone.html '''Little English Halo Blog:''' ''New Halo 4 Info Blowout via ExpertZone!'']</ref> The development of ''Spartan Ops'' saw the largest influx of new characters, along with corresponding facial and voice talent, and gameplay/sandbox elements into any property of the ''Halo'' franchise since 2001.{{Ref/Reuse|RTX Halo 4 panel}} 343 Industries will be supporting additional ''Spartan Ops'' missions for months after launch of the game and unlike ''Reach'' challenges, players have the opportunity to play from the beginning of the episodic campaign regardless of when they started playing. The first "season" is included with the price of the game, though 343i has not ruled out charging players for additional ''Spartan Ops'' seasons.<ref name="NYDN 4302012">[http://www.nydailynews.com/entertainment/system-update-halo-4-preview-glimpse-return-master-chief-article-1.1068510?pgno=1 '''NYDailyNews.com:''' ''SYSTEM UPDATE: Halo 4 preview, with our first glimpse into return of Master Chief'']</ref> Frank O'Connor has stated that ''Spartan Ops'' will "bridge the gap" between the events of ''Halo 4'' and the future release of its sequel.{{Ref/Reuse|NYDN 4302012}}

The development of ''Spartan Ops'' came to fruition under the ideals of persistent, fresh replayability and small additions to the fiction surrounding the ''Reclaimer Trilogy'' and ancillary content.{{Ref/Reuse|Guardian 632012}} Each episode of the series, gameplay-wise, was meant to enhance the significance of the events the player is experiencing, and as such, simplistic single-objective missions were not a focus of ''Spartan Ops''. Frank O'Connor in an interview with The Guardian states that the stories and events have been loosely laid out for "a few years";{{Ref/Reuse|Guardian 632012}} the success or failure of ''Spartan Ops'' may lead to a continuation of the series past 2012-2013 with a "''known beginning, a middle, and an end.''"{{Ref/Reuse|Guardian 632012}} The first season of ''Spartan Ops'' as of June 2012 was noted as being "''very rigid''" with the direction of the story having already been mapped out from beginning to end. There are currently no plans for a second season of ''Spartan Ops''. However, Frank O'Connor has stated that ''"the story of Crimson, the ''Infinity'' and those characters and events is far from over"''.<ref>[http://blogs.halowaypoint.com/Headlines/post/2013/03/28/The-Halo-Bulletin-32813.aspx '''Halo Waypoint''': ''The Halo Bulletin: 3.28.13'']</ref> The story of the cast of characters from ''Spartan Ops'' is continued in the comic series ''[[Halo: Escalation]]''.

Season One consists of ten episodes and a total of fifty missions (five missions per episode) and was released following the launch of ''Halo 4''.{{Ref/Reuse|LEHB 6272012}} The first half of Season One was released between launch day, November 6, 2012, and December 3, 2012.

Marketing for ''Halo 4'' began in June 2012 with the release of the live-action trailer ''[[The Commissioning]]'' at E3 2012. The short live-action trailer simultaneously depicts the ceremony that formally placed the {{UNSCShip|Infinity}} in active duty within the Fleet, during operations in deep space with its battlegroup, and eventually during the Promethean's assault on its systems, dragging it into the shield world of Requiem.

===Trailers===
====Announcement====
{{Main|Awakening}}
Called "''Awakening''," this trailer was revealed for the first time on June 6, 2011 at E3 2011, during the Xbox Press Briefing in Los Angeles, California. It effectively was the announcement of ''Halo 4'' as well of that of the ''Reclaimer Saga'' (originally called ''Reclaimer Trilogy''). Developed by agencytwofifteen, Digital Domain, and Anonymous Content, with music by the game's composer Neil Davidge, ''Awakening'' showed off early assets currently in-development by 343 Industries including John-117's new armor and Cortana's makeover since their last incarnations in ''Halo 3'' and the animated short film ''[[Origins|Halo Legends: Origins]]''. It would later be revealed that the trailer is set during the opening moments of ''Halo 4'', during Jul 'Mdama's Covenant boarding of the ship.

Aptly named, the trailer depicts the awakening of John-117 from [[Cryo chamber|cryo sleep]] aboard the {{UNSCShip|Forward Unto Dawn}} by Cortana shouting for the Spartan to wake up. John-117 secures Cortana's [[Data crystal chip|data crystal]] within his neural interface and proceeds to escape a raging fire engulfing him while dodging broken-off debris from the ship. Blasting open a door preventing his escape, John-117 lays his eyes on the outer surface of an unknown alien world. Standing on the very edge of the warship being torn apart by explosions, the Spartan and his AI companion view this world opening itself.

====Concept Art Glimpse====
Ending off the 10-year anniversary celebration of ''Halo Fest'' at PAX Prime 2011 in Seattle, Washington was the release of a trailer following the first panel discussing ''Halo 4''.<ref name="concept glimpse">[http://youtu.be/vAKmu2yn3Fk '''YouTube''': ''Halo Fest: Halo 4 Concept Art Glimpse'']</ref> Released on August 28, 2011, it would be the first new glimpse of the game since its reveal at E3. It featured glimpses at many of the upcoming campaign's environments, including a terrestrial world with Forerunner glyphs on the surface, several location drafts which feature distinctly [[Forerunner]] buildings and ships, concepts of the ''Forward Unto Dawn''<nowiki />'s wreckage, and some concepts of the then-unidentified Requiem. Two of these images were repurposed as the cover art for the ''Forerunner Saga'' novels, ''Cryptum'' and ''Primordium''.{{Ref/Reuse|h4panel}} Following the ''Halo 4'' title card was a quick teaser of an early iteration of the [[Promethean Knight]].

====Demonstration videos====
{{Main|Halo 4 E3 2012 Stage Demo}}
Nearly a year after the announcement of the game, 343 Industries revealed the first proper gameplay footage of ''Halo 4'' on June 4, 2012 at the Xbox Press Briefing for E3 2012. Headlining the show, the demonstration started off with the first viewing of the live-action trailer ''The Commissioning'' which synced perfectly into the events of the in-game portion of the reveal. The UNSC ''Infinity'', pulled down into the atmosphere of Requiem by the Prometheans, flies right above John-117 who determines that the advanced warship will crash nearly 78 kilometers from their position. This gameplay demonstration reveals the "ancient evil" that John-117 and his companions will fight during the course of the game, who would be revealed as the Prometheans, the ultimate group of the Forerunner Warrior-Servant caste. 343i's reveal concludes with a short cinematic montage of various environments across Requiem with a voiceover sequence by Cortana, revealing the first prominent display of Rampancy in the series.

===Halo 4: Forward Unto Dawn===

{{Main|Halo 4: Forward Unto Dawn}}
Announced on April 30, 2012, ''Halo 4: Forward Unto Dawn'' is a five-episode live-action series with a total runtime of 75 minutes, making it one of the longest marketing programs for any game in history.{{Ref/Reuse|Variety 4302012}} ''Forward Unto Dawn'' chronicles the life of [[Thomas Lasky]] from his experiences at [[Corbulo Academy of Military Science|Corbulo Academy]] decades before his service aboard the UNSC ''Infinity'', alongside his "mentor" John-117. 343i's business director, Matt McCloskey, stated that ''Forward Unto Dawn'' would allow the franchise to "make ''Halo'' accessible for people who haven't played the games." Both McCloskey and [[Frank O'Connor]] noted that the series would flesh out the fiction of the universe, particularly ''Halo 4'''s. Viewers are given background information on the various events set prior to the game and the characters set to appear in it, as well as being introduced to new elements and expanding on old ones. 

''Forward Unto Dawn'' was released prior to the worldwide launch of ''Halo 4'' on October 5, 2012,<ref name="Bulletin 5252012">[http://halo.xbox.com/blogs/Headlines/post/2012/05/25/The-Halo-Bulletin-52512.aspx '''Halo Waypoint:''' ''The Halo Bulletin 5.25.2012'']</ref><ref name="Bulletin 7122012">[http://halo.xbox.com/blogs/Headlines/post/2012/07/13/The-Halo-Bulletin-71212.aspx '''Halo Waypoint:''' ''The Halo Bulletin 7.12.12'']</ref> first as a short weekly webseries exclusively on ''[[Halo Waypoint]]'' and [[Wikipedia:Machinima.com|Machinima.com]] and later in its full 75-minute form on other devices.{{Ref/Reuse|Variety 4302012}} A 90-minute extended edition is included with the limited edition for ''Halo 4''.{{Ref/Reuse|Bulletin 51612}} Directed by [[Wikipedia:Stewart Hendler|Stewart Hendler]], filming on ''Forward Unto Dawn'' took place in [[Wikipedia:British Columbia|British Columbia]] throughout Spring 2012 and is currently in post-production in Los Angeles.

== Reception ==
{{H4 Review}}
''Halo 4'' has received extremely positive acclaim from critics, and high praise for surpassing expectations. IGN's Ryan McCaffrey gave the game a score of 9.8 out of 10, calling it "not only a success, but a bar-raising triumph for the entire first-person shooter genre,"<ref name="IGN Halo 4">[http://www.ign.com/articles/2012/11/01/halo-4-review ''Ryan McCaffrey'', "Halo 4 Review", IGN]</ref> and  praised most aspects of the game, ranging from graphics and design to enemy behaviour, and called the multiplayer "golden". Criticisms of the game were that the need to view the Terminal through Halo Waypoint "serves only to pull you out of the experience, literally and figuratively.",{{Ref/Reuse|IGN_Halo_4}} and that "some of its fetch quest-y, flip-three-switches sequences feel like they artificially lengthen the game because of how long you can get hung up on them when the going gets tough."{{Ref/Reuse|IGN_Halo_4}} The only negative of multiplayer was that the Spartan Ops mode "lacks the replayability and score-based incentives of the Firefight mode it replaces," and that the new lobby system was "a bit more cluttered and difficult to parse through than previous Halos," but otherwise praised it as "on par with what Bungie had previously established."{{Ref/Reuse|IGN_Halo_4}} His overall conclusion was that "Halo has been rebuilt. It has been redefined. And it has been reinvigorated."{{Ref/Reuse|IGN_Halo_4}}

Jose Otero of 1UP similarly praised the game, stating that 343 Industries have "created a worthy sequel to a blockbuster franchise that wasn't initially theirs,",<ref name="1UP_Halo_4">[http://www.1up.com/reviews/halo-4-review-laying-groundwork ''Jose Otero, "Halo 4 Review: Laying the Groundwork for a New Trilogy, 1UP]"</ref> and that "Halo 4 demonstrates a genuine effort to either introduce new elements or simply correct old problems."{{Ref/Reuse|1UP_Halo_4}} He also stated that "the sound design of Halo 4 benefits from having a punchier effect than the previous entries,"{{Ref/Reuse|1UP_Halo_4}} and that the game "benefits from striking art direction that draws some inspiration from J.J. Abrams' 2009 Star Trek while adding an impressive layer of detail."{{Ref/Reuse|1UP_Halo_4}} Criticism of the campaign was that while "For the most part, the narrative does well at weaving together a big-picture conflict involving the mysterious Forerunners while telling a subtle side story about Cortana's descent into rampancy",{{Ref/Reuse|1UP_Halo_4}} "the resolution to Halo 4's story doesn't make a lot of sense."{{Ref/Reuse|1UP_Halo_4}} He admitted that "the decision to adopt a perks system in Halo 4 makes sense from a gameplay perspective, since it introduces additional avenues for players to build a character that fits their distinct play style, but these same additions slightly erase elements that distinguish two of the biggest shooter franchises from one other. Halo still has the advantage of energy shields and armor abilities, but it's a shame to see the series conform to another game's mold",{{Ref/Reuse|1UP_Halo_4}} and he voiced concerns that "the short length of Spartan Ops can feel odd at first -- unless you're playing on Legendary difficulty, that is -- but the promise of more content could easily erase these concerns."{{Ref/Reuse|1UP_Halo_4}} He praised the addition of the Prometheans, which "add a wonderful element of enemy teamwork that complements the existing A.I. behaviors beautifully,"{{Ref/Reuse|1UP_Halo_4}} and concluded that "343i has done a great job of capturing the essence of Halo, tapping into the kind of options that FPS fans love."{{Ref/Reuse|1UP_Halo_4}}

Tina Amini praised the emotional impact of the campaign, stating that "I can safely say I’ve never sat through a Halo campaign quite at the edge of my seat like I have in the first title by 343 Industries,",<ref name="Kotaku Halo 4">[http://updates.kotaku.com/post/34748950516/halo-4-the-kotaku-review ''Tina Amini'', "Halo 4: The Kotaku Review"]</ref> and praised the campaign as "beautiful. It’s cinematic, and features lovely music,"{{Ref/Reuse|Kotaku_Halo_4}} and that it "humanized what was up until now mainly just a really fun, well-made series of games,"{{Ref/Reuse|Kotaku_Halo_4}} though she found that "concepts and names are thrown at you in such rapid succession that it’s difficult to follow along"{{Ref/Reuse|Kotaku_Halo_4}} and complained that "I found the Spartan Ops missions to be fairly boring."{{Ref/Reuse|Kotaku_Halo_4}} She also admitted that "gamers are afraid of change. So the addition of ordnance drops in multiplayer—basically a bonus given to players who do well during a match—might not be desirable."{{Ref/Reuse|Kotaku_Halo_4}} She also complained that "Prometheans as a new enemy class are more annoying than I expected,"{{Ref/Reuse|Kotaku_Halo_4}} and that "fighting them grew stale very quickly,"{{Ref/Reuse|Kotaku_Halo_4}} but praised their arsenal as "trump[ing] even the Covenant’s stock."{{Ref/Reuse|Kotaku_Halo_4}} Overall, she recommended that players "keep an open mind for Halo 4, because you just may enjoy it as much as I did."{{Ref/Reuse|Kotaku_Halo_4}}

Despite the well-received sales figures and positive reviews, social networking site Raptr reported that ''Halo 4''<nowiki>'s</nowiki> player population declined rapidly since its release, even worse when compared to ''Halo: Reach''.<ref name="decline">[http://caas.raptr.com/case-study-halo-4s-spartan-ops-content-updates-successes-and-failures/ '''Raptr''': ''Case Study: Halo 4′s Spartan Ops content updates — successes and failures'']</ref>

==Trivia==
*When recording dialogue as [[Avery Junior Johnson|Sergeant Major Avery Johnson]] for ''[[Halo 2]]'', [[David Scully]] humorously said, "In ''Halo 4'', I get a woman!"<ref>[http://halo.bungie.net/News/Media.aspx?mid=13890&age_verify=0 '''Bungie.net''': ''Media Player - Halo 2 Audio Outtakes'']</ref>
*The four Covenant species featured in ''Halo 4'' are the same as those featured in ''[[Halo: Combat Evolved]]'': Elites, Jackals, Grunts, and Hunters.
*In ''Spartan Ops''<nowiki>'</nowiki> pre-rendered cutscenes, some weapons use models from older builds of the game as seen in early in-game screenshots. For example, the BR85HB SR is erroneously labeled as the [[BR55 Heavy Barrel Service Rifle|BR55HB SR]] and the M395 Designated Marksman Rifle lacks a front sight.
