This article is about the Scarab model introduced in Halo 3. For other types of Scarab, see Scarab. For real-world uses of the word, see Scarab (disambiguation).
The Deutoros-pattern fortress breaker, known to humanity as the Type-47B 'Deutoros' Ultra-Heavy Assault Platform, or Scarab, is a large, heavily armored, all-terrain, quadrupedal walker. Classified as a tier-four Excavator, the Type-47B Scarab was employed by the Covenant as a siegeworks ultra-heavy artillery assault platform.
Originally designed strictly for mining operations and deep excavations on widely varied terrain, the Scarab has since been repurposed for combat. The walker is used to attack heavily defended structures and emplacements and to provide nearly-unstoppable combat support for Covenant ground forces. A heavily-fortified and dexterous mobile platform that boasts impressive levels of firepower, the Scarab is known for striking fear into its opponents.
At least two models of the Scarab exist: the Deutoros and the Protos. Both models are extremely powerful, possessing potent armament and armor. The body of a Scarab features an interior bay and command center, where many of the vehicle's essential functionaries are accessible. An infantry platform that surrounds the enclosed bay allows the defensive personnel of the Scarab to fire upon hostiles from above or eliminate other threats. Although the Scarab appears to be a traditional vehicle, it is actually a bio-mechanical construct that makes extensive use of Lekgolo. Colonies of Lekgolo worms are bound together with the vehicle's control systems, though the gestalt is seldom given complete control of the entire Scarab; the Lekgolo meta-colonies that inhabit Scarabs are often populated by particularly unruly Lekgolo individuals that can not be trusted with total control over the vehicle without causing undesired chaos. A central power junction located inside the Scarab's interior bay is one of the only locations on the walker where the Lekgolo are exposed. Due to the Scarab's reliance on the Lekgolo and their ability to operate independently, the weapons platform was never truly categorized as a vehicle by the Covenant. The Scarab was classified as a single, ultra-heavy infantry by the Covenant, which is more accurate than the United Nations Space Command's formal designation. The chassis of the Scarab is built in specialized, cavernous assemblies, such as the Assembly Forges on the now-destroyed Covenant capital city of High Charity. At these facilities, Lekgolo are fused into the carapace and appendages, and bound to the control systems. Like many vehicles, the Scarab is modularly crafted on an assembly line, where its various pieces are combined then activated.
Scarabs are not without their weaknesses. A Deutoros Scarab will be temporarily stalled if its legs sustain enough damage, causing the walker lower into a crouch-like position and allowing a would-be boarder to jump into the vehicle's troop bay. Despite its prodigious firepower, the Scarab is highly vulnerable to being boarded. The central power junction is protected only by the vehicle's external armor and the exposed Lekgolo are susceptible to weapon fire, so attacking the junction is relatively easy once a hostile boards the craft. Once the core is destroyed, the Lekgolo gestalt's tissue tears and a chain reaction will occur, which will quickly destroy the craft.
Unlike most vehicles deployed by the Covenant, the Scarab does not employ anti-gravity propulsion to move; it instead uses a quadrupedal "leg" assembly for locomotion. These jointed legs are very powerful, strong enough to even withstand the shock of low-orbital drop. Scarabs are equipped with several underside thrusters that allow the vehicle to slow its descent during its initial deployment. The Scarab can move at a relatively fast speed, with a maximum speed at 76 kilometres per hour (47 miles per hour).
The articulated legs and the spiked "feet" of a Scarab allow the vehicle to sturdily grip the ground, climb over obstacles, and even kneel down. The legs are also very nimble, affording the Scarab a surprising degree of maneuverability; for example, the Deutoros Scarab can mantle inclines in excess of forty-five degrees and can attempt to right itself if it is knocked off balance. The Scarab is capable of carrying out excavations and assaults in varied terrains and rough environments. The Deutoros Scarab is capable of operating underwater if only for brief periods.
Crew and complement
The Type-47 Scarab is occasionally used as a mobile command base, and rarely as a large-scale troop transport vehicle. An officer of the Covenant military serves as a supervisor and "pilot" aboard a Scarab. Rather than steer the walker, the Scarab's supervisor "guides" the direction of the machine and occasionally directs the artillery when needed; a Scarab's Lekgolo complement manage and carry out most of the walker's functions and processes. The supervisor often operates the Scarab's weaponry when precision is needed, as the Lekgolo have no fine control over the armaments.
As Scarabs were too valuable to operate without support, the Covenant fielded the walkers with a standard crew of one supervisor and twelve defenders when deployed in the field. The accompanying infantry and supervisory personnel aboard a Scarab serve to prevent boarders from destroying the vehicle from within or from attempting to seize the walker for themselves. A Scarab could hold as little as five security personnel, or as many as fifty aboard its infantry platform. However, twelve was generally the standard amount of defensive personnel stationed aboard a walker to allow reasonable combat efficiency on the platform. The security personnel aboard a Scarab were additionally charged with eliminating any hostiles that were able to survive the vehicle's bombardment of a location. The security personnel of Scarabs typically consisted of lances of Unggoy and Kig-Yar, as well as some Jiralhanae and Sangheili.
The primary armament of a Scarab is an ultra-heavy focus cannon mounted on the "head" at the front of the platform. The focus cannon is typically affixed to the Scarab's prow during its assembly towards the end of the vehicle's production. The weapon fires a stream of superheated plasma, capable of decimating nearly any infantry or vehicle in its path. The focus cannon is a nearly capital ship-scale energy projector capable of both mass destruction or delicate stratigraphic excavation depending on the weapon's tuning and the operator's expertise. The cannon is capable of melting through five feet of concrete, with one Scarab having enough firepower to level a small city. In the Deutoros design the cannon is housed in a cradle that is protected by flaps, which open before firing. The focus cannon has a relatively low rate of fire and is typically discharged in brief bursts. As the weapon is fired, it releases a green-glowing liquid, which may be coolant. The effective range of the focus cannon is rather short, being about 650 meters, and the blast can easily be evaded at a distance, but Scarabs have exceptional target-spotting capabilities.[Note 1] The ultra-heavy focus cannon is useful for uncovering artifacts during excavation operations.
The Scarab's focus cannon is bolstered by secondary armament that rests atop the carapace's stern. The Deutoros are equipped with secondary ultra-heavy plasma cannons which serve primarily as anti-aircraft weapons, and have a greater effective range than the focus cannon. The Deutoros carries a single spine-mounted cannon, which can rotate 360° and fire.
Additionally, the Deutoros Scarab carries three mounted Type-52 plasma cannons. These are used primarily in an anti-infantry role but are also effective against light vehicles and, to a lesser extent, light aircraft such as AV-14 Hornets. The Scarab's crew also use these weapons to repel boarders and to provide covering fire; however, if one of these plasma cannons is captured, it can be used to deadly effect against the crew and the platform's core.
The Deutoros Scarab's focus canon being retrofitted is a delicate process that requires calibrating all the coolant subsystems, as any heat spike from the core can pose a serious threat to the Lekgolo gestalt.
Despite being encountered as early as 2527 and officially observed in 2529, the United Nations Space Command did not catalog the Deutoros Scarabs until 2547. During the later stages of the Battle of the Etran Harborage, the Covenant Fleet of Glorious Interdiction deployed a number of Type-47B Scarabs in efforts to stop not only the crew of the UNSC Spirit of Fire, but also the Flood and Sentinels that inhabited the shield world. During the battle, the Flood made an attempt to capture at least one Scarab, with Flood roots erupting out of the ground around the walker and ensnaring it, forcing nearby Covenant infantry to flee. Before they could commandeer the Scarab, they were attacked by UNSC forces who eliminated the roots allowing a SPARTAN-II to take control of the walker. The captured Scarab provided a significant combat advantage for the UNSC as they fought to destroy several Covenant citadels which would provide them with a staging area in order to assault the Apex Site. Another Type-47B Scarab along with a contingent of Sangheili Honor Guardsmen were stationed at the final Covenant cidadel but the UNSC forces, with the aid of their captured Scarab were able to eliminate all Covenant forces. At least one Type-47B Scarab attempted to halt the UNSC's assault on the Apex Site but fell to the human's determined assault. A number of Type-47B Scarabs were deployed around the portal that would allow the Spirit of Fire to escape the shield world, both to counter the human forces, as well as a large Flood presence as well as hostile Forerunner constructs. They were ultimately unsuccessful in preventing the departure of the Spirit of Fire from the Etran Harborage.
Type-47 Scarabs were rarely employed by the Covenant during the sieges on the Outer Colonies, though the Type-47 saw increased field deployment in large numbers near the end of the Human-Covenant War to crush UNSC fortifications on well-defended Inner Colony worlds. Unprecedented numbers of Type-47B Scarabs were used by the Covenant during the Fall of Reach. During their initial incursions on Reach, the Fleet of Valiant Prudence deployed significant Covenant ground forces, including at least three Type-47B Scarabs at Szurdok Ridge, hiding their presence from the UNSC using several deployment spire. When the site was attacked by the UNSC on August 12, 2552, these three Scarabs provided support for Covenant ground forces as the two massive armies clashed at the landing zone. Unfortunately for the Covenant, a pair of SPARTAN-IIIs were successful in destroying an Anti-Aircraft Battery on a nearby ridge, allowing UNSC frigates Grafton and Saratoga to carry out a bombing run on the Covenant forces, wiping out the three Scarab walkers. Towards the end of the Fall of Reach, Type-47B Scarabs and other Covenant heavy armor were deployed to stop UNSC forces from escaping from the doomed planet.
During the final hours of the Battle of Installation 04, the Covenant deployed a Type-47B Scarab to combat swarming Flood forces in the arid badlands around the downed UNSC Pillar of Autumn. During the battle, remaining UNSC personnel on the ringworld launched an assault on the Covenant forces, with the objective of drawing them away from the Autumn while SPARTAN John-117 boarded the cruiser. However when the Chief's commandeered Banshee approached the ship, the Scarab soon took notice and moved to ambush the Spartan. Fireteam Raven was quick to act, boarding a Falcon and proceeding to pursue the walker. Despite its best efforts, the team of ODSTs was able to successfully board the Scarab, wiping out its entire complement of soldiers and destroying the core.
When the High Prophet of Regret invaded Earth in October, 2552, he deployed at least five Type-47 Scarabs to Mombasa, Africa, with at least one of them being a Deutotos model. Two Scarabs were placed in New Mombasa, while another three were deployed in Old Mombasa. One of the Scarabs in New Mombasa was apparently charged with destroying the Mombasa Tether. Shortly after Solemn Penance's retreat, one of these was stationed in the partially-flooded Kikowani Station, where it was engaged and neutralized by Alpha-Nine.
On the morning of October 21 when the High Prophet of Truth's Jiralhanae-led reinforcements arrived over Kenya, as Alpha-Nine members Edward Buck, Veronica Dare and the Rookie escorted a high-value asset: the defecting Covenant Huragok Quick to Adjust containing information from a subroutine of the city's Superintendant artificial intelligence, they witnessed several Type-47 Scarabs being deployed by the massing Covenant warships. While most of them ignored or didn't notice the humans, one of the Scarabs did take notice and opened fire on the Olifant containing the Huragok with its focus cannon, heavily damaging the vehicle and forcing the team to abandon it outside of the Uplift Nature Reserve.
During the Battle of Voi, a Type-47B Scarab was deployed into a lake bed near Traxus Factory Complex 09 after all of the Covenant Anti-Aircraft defenses in the area were cleared by a mounted UNSC assault force. John-117 was able to eventually bring down the walker, allowing the human forces to regroup and push on to their final objective, a Covenant Anti-Aircraft Cannon. The Prophet of Truth deployed multiple Type-47B Scarabs during the Battle of Installation 00. Outside Installation 00's Cartographer, John-117, with the assistance of a UNSC armored unit, destroyed a Type-47 Scarab. During the battle outside the Citadel, a pair of Type-47 Scarabs were deployed as a last-ditch effort by the Covenant to prevent the UNSC-Sangheili forces from reaching the Prophet of Truth. Despite their best efforts, both Scarabs were neutralized by the Master Chief, and with the death of the final Prophet Hierarch shortly later, the Covenant was brought to an end.
Halo 3, Halo 3: ODST, and Halo: Reach
Halo 3 Scarabs have far more destructible parts than their Halo 2 predecessors. Destructible armor covers each joint of a Scarab's legs, and doing enough damage to the legs will cause the Scarab to go into lockdown, making it stop moving altogether. The flaps covering the main gun can be destroyed, though this does not affect the gun's operation. The crest on and around the rear anti-air turret can be completely blown off, slowing the turret's rate of fire and reducing the size of its plasma bolts. Two side door panels near the bottom of the Scarab's back can be torn off, allowing entry onto the vehicle.
A Scarab's rear armor possesses a glowing red circle; inflicting enough damage upon this circle will detach the armor, leaving the Scarab's core exposed. The core itself can be destroyed; its destruction will trigger a massive explosion that blows the Scarab into pieces, leaving few parts intact.
If one can successfully manage to board the Scarab in Halo: Reach, they will find that only the core of the Scarab can be destroyed. All other parts of the Scarab, including Plasma Cannons, cannot be destroyed. Destroying the core of the Scarab will also not destroy the Scarab itself. Instead, it will expose a hole in the Scarab, which bleeds orange Lekgolo blood if shot.
Halo Wars features the Deutoros Scarab as a playable unit in Skirmish and multiplayer modes for Covenant leaders, though it is smaller for the sake of gameplay. Each Scarab costs 3,000 resources and 20 population in Skirmish, with no upgrades available due to their cost and is built at the Covenant citadel. Up to two can be spawned at a time in a Standard mode and four in Deathmatch mode. The last Title Update for Halo Wars enhanced the Scarab by providing an additional 25% hitpoints and produces increase damage of 25%, and is now capable of surviving four direct MAC blasts as a result of the improved hitpoints.
The Scarabs excel at attacking vehicles and infantry with their powerful weapons, though aircraft take longer for the Scarab to take down. Scarabs are very mobile, being able to climb over most obstacles. Only certain obstructions, like craters or fire, can block them. In the campaign level Beachhead, the player may use a Spartan to commandeer an abandoned Scarab. Commandeering this Scarab and using it to destroy twenty-five enemy units unlocks the achievement Beaming With Pride.
Scarabs are extremely difficult to destroy. Overwhelming it with a massive attack force works well, particularly when using anti-vehicle units like the SP42 Cobra or some Hunters, but a significant portion of the attack force will be lost in the process. An upgraded MAC blast or carpet bomb can destroy a Scarab rather quickly, as can a group of AC-220 Vultures using their missile barrages. Covenant leader units' special abilities can inflict massive damage on a Scarab, with the Prophet of Regret's cleansing beam being a good example.
Winning a Skirmish game with two Scarabs unlocks the 2 Bugs Are Better Than 1 achievement.
