HRUNTING Mark III (B) Cyclops

The HRUNTING Mark III Exoskeleton, commonly known as the Cyclops, is a bipedal powered exoskeleton used by the United Nations Space Command. It is a redesigned version of the Mark III exoskeleton, a predecessor to the MJOLNIR Powered Assault Armor.

Development history
Unlike the form-fitting armored suits that began with the retroactively named Mark IV, the predecessors of MJOLNIR were bulky powered exoskeletons. In 2511 Dr. Catherine Halsey decided to scrap the earlier iterations due to their size, lack of maneuverability, and power inefficiency. She and the Office of Naval Intelligence's Materials Group abandoned the exoskeletons for Project: MJOLNIR, leaving most of the exoskeletons (even the comparatively successful Mark IIIs, which had been introduced only a year earlier) in Reach's titanium mines.

In 2513 the Materials Group's research team on Algolis, who were working on a separate project known as HRUNTING, began to refine the Mark III. Working at Weapons Research Facility T12A, the HRUNTING team made their own development breakthroughs until they created a revised "[B]" variant of the Mark III, which they called the Cyclops. Unlike the original Mark I, II, and III exoskeletons, the Mark III [B] was intended to perform non-combat military roles such as construction, matériel transportation, terraforming, and dock work. The Cyclops eventually saw limited deployment as a logistical support unit with the Marine Corps. Operators were forced into combat on rare occasions, during which the Cyclops proved very effective as an ad hoc anti-matériel and anti-fortification platform.

Numerous variants of the Cyclops have been designed since the introduction of the Mark III [B], including some versions that are armed and up-armored; others are marketed toward civilian agencies. Following the development of the Cyclops the HRUNTING project was merged with the similarly oriented YGGDRASIL project, resulting in the creation of several exoskeletons and armor defense systems beginning with the Mark I Armor Defense System.

Design
The Cyclops is a very large platform, standing 4.3 meters (14.1 feet) tall and 3.7 meters (12.1 feet) wide. The operator is harnessed within a sealed cockpit that features a transparent canopy and a roll cage. In order to make controlling the Cyclops feel more natural the operator is encased in an internal active-impedance haptic interface exoskeleton that controls the movement of the vehicle itself and provides force feedback. As a result the Cyclops feels like an extension of the operator's body despite not being "worn" in the same sense as smaller powered exoskeletons such as MJOLNIR.

The Cyclops' most prominent feature is its two large arms which feature powerful hand-like torque-amplification gauntlet. These manipulators can effortlessly crush a Sangheili's body and, with the assistance of a wrist-mounted pile driver, can shear large pieces from Wraith tanks and even citadels, the latter of which possess starship-grade armor plating. In keeping with its intended role as a support unit the Cyclops can use its manipulators and various arm-mounted tools to repair vehicles and structures. Due to the Cyclops' nimble design these repairs can be completed very quickly, even in the field.

The Cyclops is surprisingly lightweight for its size thanks to the advanced materials created by the engineers and scientists on Algolis. It is also quite agile, capable of outpacing even Spartan-IIs at a speed of just over 48 kilometers per hour (30 mph). Hydraulic-buffered shocks in the exoskeleton's feet ensure that rough terrain does not hinder the mobility of the Cyclops and allow it to jump short distances. Like the original Mark III exoskeleton the Cyclops features an externally mounted fusion reactor as its power supply, though the unofficial Mark III [B-II] variant often replaces the standard reactor with an alternate power source.

Models
The Cyclops' ease of use and load carrying capacity have led to the creation of numerous iterations of the Cyclops as of 2558:
 * Mark III [A]: The initial prototype of the Cyclops, this model is equipped with neural interface controls and features a sealed canopy used as an armored carapace.
 * Mark III [B]: This is the initial, unarmed production variant used for structural demolition and logistical support.
 * Mark III [B-II]: An unofficially designed variant of the [B] model, this exoskeleton features redesigned feet and a more robust, sealed cockpit. Many are equipped with alternate power-packs that replace the expensive fusion generator with hydrogen-burning turbines or high-density power cells.
 * Mark III [B1]: An upgrade to the [B] model, this variant is produced by Hannibal Weapon Systems. It features composite armor plating and hardpoints for weapon installation. This model is popular with paramilitary security forces on the cities of Earth.
 * Mark III [M1]: Produced by Lethbridge Industrial, this variant is armed and are used as multi-purpose assault platforms with heavy weapon hardpoints installed on the "shoulders". They are protected by Titanium-A armor plating. This variant is currently undergoing field trials with the UNSC Army.

Variants
There are several minor Cyclops variants with no official categorizations. Most of these variants follow common themes in terms of their loadout and the scope of their modification. Some alterations are made to enhance their suitability in specific climates. The following are variants in service as of 2558:


 * Peacekeeper: Commonly used by law enforcement SWAT teams in the megacities of Earth, this variant is a essentially a Mark III [A] unit equipped with a riot-control shield. It also mounts a low-pressure autocannon capable of firing a variety of less-lethal munitions. Most Peacekeepers were destroyed when they were pressed into active combat duty.
 * Protector: Usually derived from older B-II units, Protectors are deployed in high-threat civil rescue missions. They are often operated by firefighters and medical response teams for deployment in situations where larger vehicles cannot fit, and protect workers from high-risk environments. They are usually configured with a large tank of fire-retardant foam, a high-pressure projector, and a high-torque gripping arm for ripping apart damaged vehicles to reach occupants trapped inside or to break the reinforced walls that are generally found in arcologies.
 * Breaker: These units are used for ship-breaking and construction. They are equipped with specialized tools such as high-power plasma-cutters, hydraulic rams, or an assortment of cutting blades that allow them to complete their tasks. The Breaker allows individuals to safely take apart shattered ship hulks and stations that remain in orbit around a planet. They are also used for excavating half-melted buildings on the surface of glassed colonies.
 * Hazops: This variant features a biological laboratory-grade environmental sealing and a heavy flamethrower. Hazops units are occasionally assigned as support vehicles to Spartan assessment and containment teams at Forerunner sites which are believed to house Flood samples. When Flood spores are found by these units, it is often necessary to destroy the entire exoskeleton, as cleaning the whole suit for traces of the Flood supercell is extremely challenging. Although only explored in simulations, some believe it is possible for the Flood to take control of the suit and its operator and further augment the exoskeleton.

Halo Wars
The Mark III [B] Cyclops is a playable unit in Halo Wars. In the campaign, the Cyclops appears only in the level Repairs. In skirmish and multiplayer, the Cyclops is available only if Sergeant Forge is the player's selected hero unit. The Cyclops is designed to be an anti-structure unit with only melee attacks and cannot attack aircraft.

The Cyclops requires 125 resource units, a tech level of one, and one population slot. It has the following upgrades:
 * Repair Kit - Allows the Cyclops to repair buildings and ground vehicles. The upgrade costs 400 resource units and requires a tech level of two.
 * High-Torque Joint - Improves the Cyclops' movement speed. The upgrade costs 900 resource units and requires a tech level of three.

Halo Wars 2
Unlike its Halo Wars counterpart the Cyclops in Halo Wars 2 is an anti-vehicle unit armed with a gun, though it still cannot attack aircraft.

Production notes

 * The Cyclopes are a race of one-eyed giants in Greek mythology. This Cyclops resembles them by its huge stature and visor in the center of its "head" resembling a single eye. Hrunting is a magical sword given to Beowulf in the Anglo-Saxon poem of the same name. It had never failed in battle until Beowulf's fight with a dragon which ultimately resulted in the hero's death.
 * From a gameplay perspective the Cyclops exoskeleton is based on the Cyclops unit from Ensemble Studios' game Age of Mythology. It is similarly a large unit that deals heavy melee damage. Their alternate attacks are also similar; when secondary ability bar has charged, the Cyclops will lift a nearby infantry unit and hurl it at the enemy forces for additional damage. In Halo Wars, the Cyclops' secondary ability allows it to tear a vehicle apart and hurl the chunks at enemy forces in a similar manner.

Trivia

 * Though the standard plural form of Cyclops is Cyclopes, UNSC personnel in Halo Wars consistently say "Cyclopses" instead.
 * The Cyclops and the Gremlin are the only known UNSC vehicles named after mythological creatures instead of UNSC's tradition of naming ground vehicles after real animals.
 * Earlier in-game models of the Cyclops had a yellow polarized canopy reminiscent of the SPI and MJOLNIR EVA helmets.
 * The Cyclops' height of 11.7 feet refers to John-117's Spartan tag.

Non-canon background
Graeme Devine, the lead writer of Halo Wars, created a backstory for the Cyclops that is rife with continuity errors. This was made to provide narrative context for the game development team. However, Devine states on his blog that the background stories he created are "essentially fan fiction" and should not be regarded as canon.

The essay states that the Marine Corps designed the Cyclops as a shock infantry platform to combat the Insurrectionists, and that the program competed with the "fledgling" Orbital Drop Shock Troopers. The Cyclops is said to have been removed from service after the initiation of the SPARTAN-III program. Canonically the Cyclops was originally produced as a support platform and the ODST had been in service for centuries. The SPARTAN-III program was top-secret and served an entirely different role from that of the Cyclops, so the activation of the Spartans would have no bearing on the platform's deployment.
