The '''MJOLNIR Powered Assault Armor/Mark VI''' was the third major version of the [[MJOLNIR Powered Assault Armor]]. The last mainline MJOLNIR GEN1 suit to be widely issued,{{Ref/Reuse|H4}} the Mark VI was issued to the few surviving [[SPARTAN-II program|Spartan-II supersoldiers]] in [[2552|October 2552]], replacing the [[Mark V]]. Shortly after the end of the [[Human-Covenant War]], it was replaced by the [[Mark VII]]{{Ref/Novel|Gla|Page=213}} and [[MJOLNIR Powered Assault Armor (GEN2)|MJOLNIR [GEN2]]]. The Mark VI could still be requisitioned by [[SPARTAN-IV program|Spartan-IV]] personnel as late as [[2558|October 2558]], albeit upgraded to function with the GEN2 suite.{{Ref/Game|Id=H4|H4}}{{Ref/Game|Id=H5G|H5}} In early [[2559]], in the midst of the [[Created conflict]], the Mark VI armor has been upgraded to the [[MJOLNIR Powered Assault Armor (GEN3)|GEN3]] platform.{{Ref/Reuse|DH}}{{Ref/Marketing|Id=Step|HINF|Become|Step Inside}}

== Overview ==
Late into the war, as work on the MJOLNIR Mark V was being completed, a top-secret parallel development lab in [[Songnam]], [[Korea]], began work on their own prototype of Project: MJOLNIR. This project came to be known as [[MJOLNIR Powered Assault Armor/Black|MJOLNIR: BLACK]], a standalone "skunkworks" prototype of the Mark VI MJOLNIR armor.{{Ref/Anthology|Evo|Story=Blunt Instruments}} Using data from the existing and in-development versions of the MJOLNIR armor, the Seongnam team was able to produce a suit with many technical advancements not yet available to the standard Mjolnir system. After extensive testing of prototype models in combat against the Covenant, the BLACK prototype was eventually inducted into the Mjolnir line and officially designated as the sixth version.{{Ref/Book|Enc09|Page=89}} It was approved for use after the [[Fall of Reach|loss]] of [[Reach]] and equipped to the surviving Spartan-IIs after their arrival on Earth.

The Mark VI is capable of taking full advantage of the physical capabilities of a Spartan. The suit is constructed in overlapping layers. It is environmentally sealed, capable of [[extra-vehicular activity]] and operations in toxic atmosphere. It is hardened against [[electromagnetic pulse]]s and radiation, and has filters that are effective at removing toxins and bacteria from the local atmosphere.{{Ref/Book|Enc09|Page=92}}

The armor's shell is composed of a multilayer alloy of remarkable strength and has been augmented with a refractive coating capable of dispersing a limited number of impacts from Covenant energy weapons. The suit contains a gel-filled layer underneath a thick black armored bodysuit. The gel layer regulates temperature and can reactively change its density. The inner skinsuit is made of a moisture-absorbing synthetic material linked to an environment control computer and the occupant's [[neural interface]].

[[File:H2A - MC face.jpg|thumb|250px|left|John-117 in his newly acquired set of Mark VI armor.]]

Spartans are implanted with a [[Spartan neural interface|unique model]] of the [[command neural interface]]. This network translates electrochemical signals to digital code and routes them through an interface connection at the rear of the skull. Through this interface, the user's thoughts command the armor's movement and use of weapons, and input from the onboard sensors comes directly to the user's mind. The synthesis of machine and mind is so fast that it is almost impossible to chart reaction time.

Each suit of Mjolnir Mark VI armor contains a layer of superconducting computer memory. Envisioned by Dr. [[Catherine Halsey]], this revolutionary layer forms a network, capable of supporting the kinds of artificial intelligence usually reserved for starships, a piggyback system.

The suits also contain a strength-enhancing layer.  This marvel of engineering uses piezoelectric properties to enhance and assist a Spartan's already prodigious muscle power, and grant superhuman feats of might.

The Mark VI largely solves problems with the previous versions of Mjolnir armor. It has an improved energy shielding system, powered by a smaller fusion pack on the wearer's back. This shield system is much stronger and charges more quickly than the Mark V's. The suit also has denser yet less bulky armor plating. These streamlined plates have fewer grapple points than the Mark V so that an enemy has fewer advantages in close combat.{{Ref/Book|Enc09|Page=90}}

In addition, the Mark VI's liquid crystal and hydrostatic gel layers received significant improvements over the previous version. The liquid crystal layer increases the strength of the wearer by a factor of five in addition to amplifying the user's reaction time by the same factor.{{Ref/Book|Enc09|Page=??}} The hydrostatic layer features a lock-down device, which protects the muscles and joints of its Spartan wearer from heavy-impact injuries.{{Ref/Book|Id=ENC91|Enc09|Page=91}}

In addition to major component upgrades the Mark VI introduces a number of smaller technical improvements to components. These included recoil-compensating actuators which handle weapon feedback. As a Spartan is firing a weapon in combat, these actuators handle a weapon's recoil reducing it without affecting the performance of the Spartan user. The Mark VI also possesses an improved computer system which continuously monitors weapons, biological functions, and motion through an intelligent [[motion tracker]].

The third stage in the MJOLNIR evolution, the Mjolnir Mark VI is a fully neural-linked system. With an onboard [[artificial intelligence]] using the human mind for parallel processing, the SPARTAN-II/MJOLNIR combination was the most devastating intelligence tool ever created.

==== Mark VI MOD ====
{{Main|Mark VI MOD}}
Referred to as Mark VI MOD,{{Ref/Reuse|MCMCC}} the Mark VI Mjolnir armor worn by MCPO [[John-117]] following the end of the Human-Covenant War was updated by UNSC AI [[Cortana]] during his four years and seven months of cryosleep aboard the {{UNSCShip|Forward Unto Dawn}}. Cortana used [[nanotechnology|minifacturing]] and diagnostic systems to repair and alter John's armor. This armor closely resembles an earlier line of Mark IV armor.<ref name="ScienceOfHalo">[http://www.youtube.com/watch?v=QjswoU39AOY ''YouTube'' - ''The Science Behind The Halo Series'']</ref>{{Ref/Book|Id=h4evg|H4EVG|Page=10}}<ref name="Halo Canon">[https://www.youtube.com/watch?v=E2geKWjvhPY ''Halo Canon'' - ''Interview'']</ref> She also rewrote the suit's firmware, altering the HUD as well as improving the suit's shield recharge rate and its compatibility with Covenant and Forerunner [[Armor abilities|armor plugins]].{{Ref/Level|Id=dawn|H4|Dawn}} This armor was damaged during the [[Mission to Installation 03]] and replaced by a similar [[MJOLNIR Powered Assault Armor (GEN2)|GEN2 Mjolnir armor]] variant.{{Ref/Twitter|Id=grimt|GrimBrotherOne|782402924353757184|Jeff Easterling|Quote='''Blue team uses Gen-2 MarkVi?!

=== GEN2-related variants ===
Some Mark VI variants are superficially similar to the [[MJOLNIR Powered Assault Armor (GEN2)|GEN2 Mjolnir armor]] introduced in the wake of the [[Human-Covenant War]].<ref name="HWFred">[https://www.halowaypoint.com/en-us/universe/characters/frederic-104 ''Halo Waypoint'' - ''Frederic-104'']</ref> By [[2552#October|October 20, 2552]], [[Frederic-104]] and [[Linda-058]] had been issued prototype [[MJOLNIR Powered Assault Armor/Centurion|Centurion]] and [[MJOLNIR Powered Assault Armor/Argus|Argus]] variants, respectively. Both of these armors have a bodysuit similar to that of the GEN2 armor and they would stay superficially unchanged with the transition to the GEN2 platform.{{Ref/Game|H2A|Detail=''[[Terminal (Halo 2: Anniversary)|Terminals]]''}} Fred and Linda received upgraded GEN2 versions of their suits in the post-war era, while [[Kelly-087]] donned the GEN2 [[HERMES-class Mjolnir|Hermes]] variant at some point after being rescued from the shield world [[Trevelyan]].

==== Mark VI GEN2 testing variant ====
This Mark VI looks similar to the hybrid GEN2/Mark VI [GEN1] armor, although it uses a slightly different techsuit from the mainline GEN2 armor.<ref>[https://www.instagram.com/p/y79tu0CRUW/?taken-by=hmcc_spartans ''Instagram'' - ''hmcc_spartans'']</ref>

=== GEN2 ===
==== Variants ====
Following the development of the GEN2 Mjolnir in the wake of the Human-Covenant War, the external components of the original Mark VI armor were reproduced as a variant of the new generation. This Mark VI incorporates slight modifications to accommodate the different base architecture of the GEN2 system.{{Ref/Reuse|H4}}{{Ref/Reuse|H5G}}
* '''Hybrid GEN2/Mark VI [Gen 1]'''
This variant of Mark VI uses many components from the base Mark VI as they have proven to be functional even after taking significant damage.{{Ref/Game|Id=H5G1|H5G|Armor customisation (Halo 5: Guardians)|Armory|Detail=Mark VI GEN1 Scarred helmet description|Quote=Constructed with the utmost care and multiply redundant subsystems, MARK VI helmets can remain functional even after horrendous damage. }}

* '''GEN2 Mark VI'''
This variant of Mark VI keeps all the designs of the original Mark VI armor, but has been completely updated to modern powered assault armor standards. This variant has a classic GEN1 heads-up display, a solid collar frame and branch locking system. It is also equipped with a Class-3B Essen shield distributor. The [[Ordnance Commission]] allowed this variant to be used due to the original Mark VI's performance.{{Ref/Reuse|H4EG}}

===GEN3===
{{Quote|Hey Chief is that Mark VI armor? GEN3? Both? Neither? Does it have nanomachines?|A Marine during the [[Battle for Zeta Halo]].{{Ref/Game|Id=INF|HI|Marine dialogue}}}}
On February 10, 2559, the Materials Group manufactured a complete set of GEN3 Mark VI armor for [[John-117]].{{Ref/Marketing|Id=DH|HINF|Discover Hope}}<ref name="MCMCC">[https://www.youtube.com/watch?v=Le6WYZmWkDs MegaConstrux Master Chief Collection]</ref>{{Ref/Site|Id=CFDespite|URL=https://www.halowaypoint.com/en-us/news/despite-distance|Site=Halo Waypoint|Page=Canon Fodder - Distance Despite|D=31|M=08|Y=2020}} By October 7, this armor was also worn by [[Frederic-104]], [[Kelly-087]] and [[Linda-058]]. It looks aesthetically similar to a [[MJOLNIR Powered Assault Armor/Mark IV|MJOLNIR [GEN1] Mark IV]] armor variant they used during [[Operation: WARM BLANKET]]. By 2560, the GEN1 Mark VI shoulders and the GEN2 Mark VI MOD shoulders were both made by the Materials Group to be compatible with the GEN3 Mjolnir platform.{{Ref/Game|Id=HIMKVIGEN1|HINF|Armor customization (Halo Infinite)|Armor Hall|Detail=UA/Mark VI <nowiki>[GEN1]</nowiki> - Shoulders Description|Quote=Sometimes the best solutions are the ones that stand the test of time.}}

== Armor components ==
[[File:H4-MJOLNIR-Skinsuit.jpg|thumb|250px|The Mark VI skinsuit.]]
* '''Inner skinsuit''': The inner skinsuit is made of a moisture-absorbing synthetic material linked to an environmental control computer and the occupant's neural interface. It controls the suit's temperature and actively changes how the suit fits the user.{{Ref/Novel|Id=FoR3|FoR|Page=90}}
* '''Integrated communications helmet''':{{Ref/Game|H3|Armor customization (Halo 3)|Armory|Detail=Mjolnir Mark VI helmet description|Quote=Integrated Communications Helmet, Mjolnir: This standard-issue helmet for the Mjolnir Mark VI Powered Assault Armor has been in use since October 2552. It is compatible with all Mjolnir variants.}}{{Ref/Game|Id=armory|HR|Armor customization (Halo: Reach)|Armory|Detail=Mark VI helmet description|Quote=Data gathered from these field tests will be used to improve the final production model.}} The ICH is one of the most vital aspects of the MJOLNIR system. It is made of [[Titanium]], contains key features like a [[Heads Up Display]], and can identify equipment and display information about it when it is picked up by the wearer. Another feature is the direct neural interface system, which connects to a Spartan's neural implants. Two core processor chips are implanted into the subject's skull at the rear of the head. This is essentially comparable to an on board computer using parts of the human brain for processing - when the connector at the rear of the subject's head and receptors in the brain link to the helmet's on board sensors it creates the neural link needed to move the MJOLNIR suit. The helmet also contains equipment to protect the user in hostile conditions, such as filters to remove toxins from the atmosphere, an oxygen supply to provide air to the wearer during EVA, thermal and motion trackers, radio communicators, solar-powered lighting, and imaging and video gear. The helmet also contains an AI housing located on the back of the helmet.
* '''Titanium alloy outer shell''': The outer shell of the Mjolnir armor is comprised of a fairly thick titanium alloy. This plating covers the chest, arms, hip, legs, calves, feet and hands. This alloy is very resilient, can take significant damage, and is nearly impervious to small arms fire. While enough shots from armor piercing rounds will breach the outer shell, the suit can take a few glancing blows from them without compromising the armor. The outer shell of the all Mjolnir suits is covered with a refractive coating to help disperse the heat experienced from Covenant energy weapons. However one or two direct hits from any Plasma weapon will compromise the armor plating.
* '''Titanium nanocomposite bodysuit''': Sandwiched between the external armor and the internal padding is a thick black armored bodysuit. This suit has numerous functions, small but vital to the safety and survival of the wearer. The bodysuit is made of a titanium-based material, making it very strong and yet very flexible. It also serves as another layer of protection against ballistics attacks and is coated with a heat resistant material to disperse heat from plasma weapons.
* '''[[Hydrostatic gel]]''': Underneath the armored bodysuit is a gel-filled layer, this gel layer regulates the temperature of the suit and can re actively change its density to conform to the wearer's shape - the temperature inside the suit is controlled by the moisture absorbing cloth suit underneath the hydrostatic layer. The hydrostatic gel layer can also be pressurized to various levels to potentially save the wearer's life should the wearer be subjected to high G forces or a high velocity impact; however, over-pressurizing this layer can cause [[wikipedia:nitrogen embolism|nitrogen embolism]]s.{{Ref/Novel|FS|Page=13}}{{Ref/Novel|GoO|Chapter=1}}
* '''[[Polymerized lithium niobocene|Reactive metal liquid crystal layer]]''': Sandwiched between the external armor and the internal padding is a layer of piezoelectric material that deforms along a preferred axis when exposed to an electric charge. This layer acts as synthetic muscle, allowing the Spartan access to approximately five times their unarmored strength when using the Mark VI due to new optimization of the crystalline geometries.{{Ref/Reuse|H4EG}}{{Ref/Reuse|ENC91}}
* '''Memory-processor superconductor layer''': A layer relatively new to the Mjolnir line, introduced with the Mark V, that is capable of housing an AI. Comprised of the same material as a starship's AI system, this layer allows an AI to travel with a soldier into the field.  The AI can then aid the soldier in software intrusion, hardware hacking, and espionage by listening to enemy chatter.{{Ref/Novel|FoR|Page=286}}
* '''Magnetic weapon holder strips''': Powerful magnets are placed on the legs, waist, and back of the suit to hold any equipment with a magnetic property. The suit also contains a magnet system on the boots of the MJOLNIR suit that allow its wearer to stay attached to a metal surface in Zero G environments and can be toggled on or off by the wearer.
* '''[[Energy shielding#Human energy shielding|Energy shields]]''': First tested with the Mark IV, made standard with the Mark V, and later refined with the Mark VI, the energy shield device is reversed engineered from Covenant technology. Beginning prior to [[2531]], forty scientists and technicians would spend the next two decades attempting to make some use of the technology. For decades the attempts at cracking their technology had met with failure after failure, some had given up and others in the scientific community believed the energy shield technology could never be cracked. However at some point before 2552 a breakthrough was made and for the first time the UNSC had successfully cracked and improved upon the technology.{{Ref/Novel|Id=for27|FoR|Chapter=27}}
* '''[[Pressure seal]]''': The pressure seal is a vital component to the MJOLNIR system, it keeps the system airtight, underwater or in space. The seal is very strong and will only break under extreme pressure, such as in a high velocity impact or when the hydrostatic gel has been over pressurized.
* '''[[Biofoam|Automatic biofoam injectors]]''': Biofoam injectors are an integral part of the systems that keep a SPARTAN-II functioning in battle. Biofoam is a medical gel that is used to fill and seal a wound automatically, it is also used to treat any infection that could occur as a result of the wound.
* '''Fusion reactor''': The fusion reactor is the most essential part of the Mjolnir system, as it provides power to all equipment on the armor - the reactor is built into the suit and allows for nearly unlimited movement. The fusion reactor in all versions of the Mjolnir armor are half the size of a normal battery pack used by Marines.{{Ref/Novel|FoR|Chapter=13}}{{Ref/Reuse|for27}}
* '''[[Force-multiplying circuit]]s''': Located throughout the armor, these systems boost the force applied by the user. They make hand-to-hand combat easier, but also make the armor difficult to adjust to; a slight motion can be translated into a potentially harmful one if not conducted correctly. For this reason it is only possible for Spartans to use this armor, as their strengthened bodies are able to withstand the increased power and speed of movement, which, in un-augmented human bodies, results in broken bones or death, due to spasms caused by the pain of broken bones.
* '''[[Reactive circuit]]s''': Reactive Circuits are systems installed directly linked to the [[Spartan neural interface]]. They amplify the wearer's reaction time by connecting directly to the thoughts of the wearer, making it much easier to control and allowing for the soldier to be both more efficient and have a higher survival rate in combat.
* '''[[MJOLNIR power supply control unit|Power supply control unit]]''': Manages the power supply of the armor.
* '''[[Mark VI BIOS|MJOLNIR Mark VI BIOS]]''': The basic input/output system, standard firmware interface for the Mark VI.
* '''Lock-down system''': The lock-down system protects muscles and joints from traumatic, high-impact injuries by seizing the suit into a rigid posture through modifying the density of the hydrostatic gel layer.{{Ref/Reuse|ENC91}}{{Ref/Level|Id=arrival|H3|Arrival}}{{Ref/Level|HR|Tip of the Spear}}<ref>[https://www.youtube.com/watch?v=eLmtVh_bmhs ''Halo Reach Legendary Edition'' developer commentary, part 4]</ref>
* '''[[Quantum mirror]]''': A part of the armor's motion sensor system, located in the shoulder pauldron.{{Ref/Novel|GoO|Chapter=25}}
* '''[[Fail-safe detonation system]]''': This system functions as a [[self-destruct]] mechanism in order to prevent a dead Spartan's armor from being compromised by hostiles. It is activated by a series of digits that only the Spartans know. When engaged, it produces a reactor overload that burns everything within a ten-meter radius, then produces a large blast.{{Ref/Novel|FS|Chapter=34}}
* '''Auto-repair and bypass nodes''': Any damage that the titanium armor plating suffers can be repaired by built-in, triply-redundant subsystems. These systems are receptive to nanomachines facilitating the repair.{{Ref/Reuse|ScienceOfHalo}} Additionally, bypass channels allow certain components to function if routing is compromised by extensive damage. Both these systems can fail, resulting in "scarred" armor plating.{{Ref/Generic|Id=H5GBScarred|Halo 5: Guardians Multiplayer Beta|Detail=''Scarred Mjolnir Mark VI description''}}
* '''[[Thruster pack]]''': Located at the back of the armor, this component provides the ability to propel the wearer over short distances and to maneuver in low-gravity environments.{{Ref/Level|H4|Shutdown}}
* '''[[Holography|Holographic emitters]]''': Unique to the GEN3 model of the armor, it has the ability to display the avatar of an AI that is traveling in the armor over the palm of the hand.{{Ref/Reuse|INF}}

== Performance and durability ==
[[File:S117returnstoEarth2552.jpg|thumb|200px|Concept Art of Mark VI plummeting to Earth.]]
The Mark VI armor was the culmination of decades of research and re-engineering its predecessors, [[Mark IV]] and [[Mark V]]. This armor was not only more condensed than its previous iterations, but it was also much more durable.

While stranded on [[Line Installation 1-4]], a Mark VI prototype worn by a member of [[Black Team]] was able to withstand being punched into a Forerunner terminal by a [[Mgalekgolo]] and keep its wearer completely intact in the process.{{Ref/Comic|HBL|Issue=5}}

After boarding the [[Forerunner]] [[Anodyne Spirit|Dreadnought]], John-117's Mark VI Mjolnir withstood impacting the [[Earth]]'s surface from mid-atmosphere.{{Ref/Reuse|arrival}}

During the [[Onyx Conflict]], [[Frederic-104]]'s Mark VI Mjolnir was able to withstand a direct hit from a [[Mgalekgolo]]'s [[assault cannon]] and not suffer any major damage.{{Ref/Novel|GoO|Page=307}}

Onboard the bow of the {{UNSCShip|Forward Unto Dawn}}'s bisected wreckage, John launched a [[M4093 Hyperion nuclear delivery system|Hyperion nuclear missile]] into the hull of an unshielded {{Pattern|Zanar|light cruiser}} in response to the [[Covenant remnants]] attack on the ''Dawn''. With his MJOLNIR's strength-multiplying circuits, John was strong enough to re-activate the hammer's seized sliding apparatus by overwhelming the jam's heavy traction simply by shoving and then kicking it into place.{{Ref/Reuse|dawn}}

Subsequent to the Ur-Didact's awakening, and during the destruction of Requiem's core, John's MJOLNIR-donned frame was cratered several meters deep into non-porous, rocky terrain. The armor proved strong enough to resist the blunt-force trauma of such an impact with no visible damage - at the minor expense of an interim concussion.{{Ref/Level|H4|Forerunner (level)|Forerunner}}

During the [[Battle over Installation 07]], John's GEN3 armor took several heavy hits from [[Atriox]], enough to stun the Spartan, but it kept functioning. After being thrown into space, the armor shut down, but it went into survival mode which was able to keep the Spartan alive for six months in the vacuum of space with no food, water, or other things vital to life aside from the suit's oxygen supply. When John was recovered, [[Fernando Esparza]]'s scan of the suit suggested that its main power cells were fried, yet once it was brought out of survival mode, the armor's [[fusion reactor]] almost instantly recharged the Pelican's depleted batteries and it resumed full functioning once again.{{Ref/Quest|Id=Warship Gbraakon|Hi|Ringfall|[[Warship Gbraakon]]}} The Master Chief later told [[the Weapon]] that the next thing that he remembered after getting thrown into space was waking up on the Pelican six months later, suggesting that he had been kept unconscious by the armor for the entire time.{{Ref/Quest|Id=The Sequence|Hi|Reformation|[[The Sequence]]}} This may suggest that the armor contains high-calorie nutrient supplements to keep its occupant alive, similar to the GEN3 [[MJOLNIR Powered Assault Armor/Mark VII|Mark VII]] armor.{{Ref/Novel|RP|Chapter=22}}

=== ''Halo 4''===
A redesigned GEN1 Mark VI armor set was one of the [[Armor customization (Halo 4)|armor permutations]] to return from earlier titles, slightly redesigned for [[MJOLNIR Powered Assault Armor (GEN2)|[GEN2]]] in ''[[Halo 4]]''. It was exclusive to beating ''Halo 4's'' campaign on [[Legendary]]. It featured no secondary skins of any type.

=== ''Halo 2: Anniversary''===
The Mark VI armor is an [[Armor customization (Halo 2: Anniversary)|armor permutation]] for Spartan characters in ''[[Halo 2: Anniversary]]'', being the default option the player starts out with alongside [[CENTURION-class Mjolnir|Centurion]] and [[HOPLITE-class Mjolnir|Hoplite]]. With the release of [[Series 3: Recon]], this variant of Mark IV would feature broader customization.

===''Halo 5: Guardians Multiplayer Beta''===
The GEN1 variant of Mark VI would return in the ''[[Halo 5: Guardians Multiplayer Beta]]'', featuring a notable redesign from its ''Halo 4'' incarnation. It featured two variants, both of which were exclusive to certain achievements unlocked through ''[[Halo: The Master Chief Collection]]''. Alongside [[HELIOSKRILL-class Mjolnir|Helioskrill]] and [[Nightfall armor]], Mark VI's two variants were among the few armor sets that were unlocked outside of ''Halo 5's'' beta.

===''Halo 5: Guardians''===
Following the beta, Mark VI was available in ''[[Halo 5: Guardians]]'', being unlockable through the [[Requisition system]]. While the GEN1 variants were originally exclusive to achievements tied to ''Halo: The Master Chief Collection'', ''Halo 5: Guardians'' would put them in the general REQ pool to be unlocked by all players regardless. A GEN2 variant would also be available, featuring the same design as ''Halo 4's'' original GEN1 incarnation.

===''Halo Infinite''===
Multiple variants of Mark IV would be made available in ''Halo Infinite''. Notably, the prototype Mark VI helmet from ''Halo: Reach'' and its attachments are available for multiplayer Spartan [[Armor customization (Halo Infinite)|armor customization]]. This helmet was originally exclusive to the [[B-class Mjolnir|Mark V [B] armor core]] before becoming cross-core in [[Season 05: Reckoning]]. GEN1 Mark VI shoulders were made available under the [[UA]] category on the [[MJOLNIR Powered Assault Armor/Mark VII|Mark VII armor core]] in [[Season 04: Infection]], and would be made cross-core during [[Spirit of Fire (Operation)|Spirit of Fire]]. 

Season 05: Reckoning also added the GEN3 Mark VI set as an armor kit on the Mark VII core, attainable once players reach the [[Rank (Halo Infinite)#Career Rank|Hero rank]] within ''Infinite's'' progression system. The [[Great Journey (Operation)|Great Journey Operation]] added the ''Halo 2-inspired'' GEN1 Mark VI as an armor kit on the Mark VII core, purchasable through the game's [[Shop]].

By the time of [[Operation: DEFIANT GLASS]] in [[2552]], [[John-117/Silver|John-117]] and the Spartans of [[Silver Team/Silver|Silver Team]] were all equipped with Mark VI armor. The suit is equipped with a heads-up display and energy shielding.{{Ref/Reuse|Contact}} However, [[James Ackerson/Silver|James Ackerson]] took the armor with him when he abandoned [[Reach (TV Series)|Reach]] to the [[Covenant]], leaving Silver Team to fight in the [[Fall of Reach/Silver|Fall of Reach]] unarmored.{{Ref/Film|Id=Reach|TV|Episode=[[Reach (TV Series)|Reach]]}}

== Production notes ==
=== ''Halo 2'' and ''Halo 3'' ===
John-117 wears a Mark VI suit throughout the campaigns of ''Halo 2'' and ''Halo 3''. The Mark VI armor experienced minor graphical changes between these two games, most notably in the design of the gauntlets. The colors are more muted, with the armor bearing a gray hue. The general shape of the HUD is the same. However the radar is slightly larger and the ammo and grenade counters are no longer enclosed in templates. The most obvious difference is that the shield meter has been relocated from above the radar to the top-center of the HUD. Additionally the radar has a radius reading, with a default 25 meters. These changes appear to be purely aesthetic in nature and have no canonical explanation, though the discoloration could be due to extended and rigorous use and the HUD changes could simply be updates.

=== ''Halo: Reach'' ===
Internally the helmet was laballed as "player_will" alongside the Security shoulders with the right version use by Emile being laballed as "emile".

The Mark VI helmet appears in ''Halo: Reach'' as a prototype, possibly [[MJOLNIR Powered Assault Armor/Black|MJOLNIR: Black]] variant.{{Ref/Reuse|armory}} Two upgrades are available for the helmet, the first of which adds a Command Network Module on the left side with a Hardened Uplink Module-3rd Generation on the right side (FC-I[2]). The second upgrade adds an up-armor plate with a Command Network Module-Improved on the right side. The top part of the helmet has a single white stripe painted down the middle. Additionally, the sun visor is colored solid black.{{Ref/Reuse|armory}}

=== ''Halo 4'' and ''Halo 5: Guardians'' ===
==== Campaign ====
John-117 continues to wear his original Mark VI suit in ''Halo 4''{{'}}s campaign, although it has been redesigned.{{Ref/Book|Id=Kenneth|[[Halo 4: Official Game Guide]] (Collector's Edition)|Page 441|Quote='''Prima''' - "''Do you ever show damage on Chief's armor that speaks to the previous games or the rest of the fiction?''" - '''Kenneth Scott''': "''Yes. The damage you see on his armor at the end of ''Halo 3'' is still mostly there.''"}} In an interview with ''Game Informer'', [[Frank O'Connor]] offhandedly mentioned that [[Cortana]] used [[nanotechnology|nanomachines]] to repair the suit.{{Ref/Reuse|ScienceOfHalo}} In ''Halo 4'', the suit still has the gash it has featured since ''Halo 3'' as it was not repaired,{{Ref/Reuse|Kenneth}} apparently because that area suffered irreparable damage.{{Ref/Reuse|H5GBScarred}} ''[[Halo 4: The Essential Visual Guide]]'' notes that Cortana fully updated the suit, and that it resembles an earlier line of the Mark IV.

John's armor in ''Halo 5: Guardians'' is largely identical to its appearance in ''Halo 4'', barring minor cosmetic updates. The faceplate has been changed from a dull shade of orange to the vibrant gold of earlier titles. The formerly gashed chestplate is now intact. The undersuit's snakeskin texture is now limited to the arms and upper torso; the rest of the undersuit is smooth, with the waist and legs sporting a subtle digital camouflage pattern. Red piping is painted around the fusion pack's vents, although in the final release of the game, the red piping on the undersuit is now an olive green color, the same as the undersuit's main color.

==== Multiplayer ====
A redesigned Mark VI armor suite is available in the [[Infinity (mode)|''Infinity'' mode]] after completion of ''Halo 4''{{'}}s campaign on [[Legendary]] difficulty. The armor in general has received several aesthetic updates, keeping it in line with GEN2's aesthetic.{{Ref/Reuse|H4}}<ref>[http://blogs.halo.xbox.com/Headlines/post/2012/09/05/The-Halo-Bulletin-9512.aspx ''Halo Waypoint'' - ''The Halo Bulletin 09.05.12'']</ref> Canonically, this version of the Mark VI is GEN1{{Ref/Game|Id=H4MarkVIGEN1|H4|Armor customization (Halo 4)|Spartan Armor|Detail=Mark VI - Description|Quote=Last series of mainline Mjolnir GEN1 armor types worn by SPARTAN-II personnel.}}, and is available for issue to [[SPARTAN-IV program|Spartan-IVs]], having been made compatible for use with GEN2 systems.

GEN1 and GEN2 Mark VI armor sets are also available in ''Halo 5: Guardians'' multiplayer. The redesigned GEN1 variant seen in ''Halo 4'' has now been retroactively classified as GEN2{{Ref/Game|Id=H5GMarkVIGEN2|H5|Armor customization (Halo 5: Guardians)|Spartan Appearance|Detail=Mark VI - Body description|Quote=Without question the most famous of all Mjolnir permutations, the GEN2 MARK VI has been completely updated to modern powered assault armor standards.}}, while the GEN1{{Ref/Game|Id=H5GMarkVIGEN1|H5|Armor customization (Halo 5: Guardians)|Spartan Appearance|Detail=Mark VI (GEN1) - Body description|Quote=Technically obsolete, the Mark VI[GEN1] Mjolnir armor maintains a legendary luster among Spartans and the general public.}} variant in ''Halo 5'' features a distinctly redesigned chestplate, codpiece, and boots, which attempt to put it more in line with ''Halo 3's'' portrayal of the armor.{{Ref/Reuse|CFConventional}}

In ''Halo 4'', the back-right of the Mark VI armor has an emblem comprising a star with two chevrons underneath. This symbol appears to be based on the insignia of the UNSC's [[Seventh Fleet]], (sans one chevron), as seen on the hulls of the {{UNSCShip|Forward Unto Dawn}} and {{UNSCShip|Aegis Fate}} in ''Halo 3''.

== Trivia ==
* In ''Halo: Reach'' the letters "FH" appear near the chin area of the Mark VI that is also present on the hood of the Warthog.<ref>[http://www.halopedian.com/images/0/0e/FH%282%29.png ''FH'' Easter egg]</ref>
* The [[:File:Operation Firepower.jpg|armor]] worn by [[marvel:Operation Firepower (Earth-1610)|Operation Firepower]] from [[Marvel Comics]]' [[marvel:Earth-1610|''Ultimate'' universe]] greatly resembles the Mark VI, combined with elements of [[marvel:Antonio Stark (Earth-1610)|Iron Man's]] armor. The helmet is nearly identical to that of the Mark VI and likewise has an orange face plate, though it features the distinctive eye slits of Iron Man's armor.
