"Frankly, other than the fact that they want to kill every man, woman and child out there, we know nothing about them. We've tagged them Locust since this degree of death has only been seen in times of plague. They're subterranean in nature. That's obvious. Aside from that, I'm afraid..."
—An unidentified human scientist dubbing the name of the Locust Horde[2]

The Locust Horde, often called the Locust Army by the humans and the Horde by the Locust, were a race of reptilian humanoids that, until Emergence Day, established their civilization and resided in the subterranean regions of Sera, known as the Hollow. It was unknown for how long that the Locust Horde lived in the Hollow, but it came to be understood that their creation was after the research project led by Doctor Niles Samson that oversaw the experimentation on children of Imulsion-infected miners at the New Hope Research Facility in order to find a cure for Rustlung - which involved mutating the children with the DNA of indigenous creatures of the Hollow, creating the Sires. The eventual shutdown of the facility and exodus of Niles Samson, with a group of scientists and subjects, to Mount Kadar led to the creation of the Locust Horde by using the embryonic stem cells of Myrrah, a child born with genetic-immunity to Imulsion, and the DNA of the Sires. The Hollow under Mount Kadar was established as the Locust capital, known as Nexus. Shortly before E-Day, the Locust Horde decided that its secondary goal was the extermination of the human race down to every man, woman and child. The Locust Horde's primary goal was to populate the surface of Sera. The Locust waged a tactically beneficial war of genocide against the Humans due to the existence of a civil war between the Locust Horde and the Lambent Locust. This civil war existed for an several years before E-Day, but was gradually forcing the Locust out of the Hollow and into a war with humanity for control of the surface. All known attempts of the Humans negotiating with the Locust Horde ended in violence, although Professor Adam Fenix believed that he could end the war peacefully.[3]

The Locust Horde consisted of a common race of Drones and all manner of other creatures that are indigenous to the Hollow. The majority of the Horde's technology was stolen or salvaged from what the Humans dumped or reverse engineered from their enemies' technology.[1][4][5][6] However, the Locust Horde was able to develop some of their own technology including small-arms weapons, heavy weapons, armor for use on their tamed beasts, munitions, architecture, and had a considerable grasp of computer technology. The Locust small-arms weaponry appeared to be at around the same level as that of humans, although the Locust arsenal seemed to be more biologically based with the use of Tickers and Nemacyst. The Locust would use nearly any weapon, whether it was one of their own design, reverse-engineered Human technology or human-made.


A typical Locust was a bipedal, muscular creature with tough skin and scales, almost seven feet tall, although many were larger. They were considerably larger than a normal human and notably stronger. Their bones were heavier and showed signs of extensive thickening.

The Locust blood was a deep reddish-orange in coloration. A Locust had multiple internal organs, including multiple hearts. The Locust required oxygen, though they seemed somewhat more resistant to the environmental hazards, most likely due to their harsh native environment.

The Locust had large eyes with good depth perception in spite of the fact that they were a subterranean race. They had a noted vulnerability to flash overcompensation response (Flash-blindness), a weakness that many offset with polarized goggles or blinders. Some subspecies had particularly strong eyesight. It was strongly believed that the Locust could see perfectly in total darkness and most seemed to possess superior senses of smell.

The Berserkers were the only known female Locust. The only known methods of Locust reproduction were either the genetic transformation of a human into a Locust or the mating of a Berserker and a Drone. It was theorized by Colonel Victor Hoffman that the Locust reproduced by tying the female down (to prevent the blind female from killing her mate) and having the male rape her. There was no evidence to support this theory.[7]

After their detonation of the Imulsion Countermeasure Weapon, the bodies of the Locust began to crystallize into an unbreakable crystal shell. The Locust had undergone a twenty-five year hibernation in which they evolved inside their shells, becoming Scions of the Swarm. When the Locust emerged, most of their scales were gone, and the scales that remained were fragments left from the crystals, appearing as yellow shards penetrating the skin. The Locust Drones also became taller and larger.



Human SpeculationEdit

"We can't stop them. We don't know where they come from. We don't know what they want. They don't even seem to want territory. All they do is kill. We can't even begin to negotiate with them, or work out their objectives, because we just don't know the first damn thing about them. That's not an enemy, Mr. Chairman. That's a monster."
—Chief of the COG Defense Staff, General Bardry Salaman describing the Locust.

To the people of Sera, the origins of the Locust are shrouded in mystery. Many theories on their origins are suggested by the remaining human population. One such example was that the Locust came from Risea, a neighboring planet, or one of Sera's two moons, and that they feed on Imulsion. The other speculation existed saying that they came from Hell, sent to purge the world of all the sinners and only sparing the pure. However, the rumors such as these are generally regarded as false.[8][9]

New Hope Research FacilityEdit

"Save the children, that's what they always say. In this case, we're truly doing it. Or at least, we're giving it our very best shot..."
—Dr. Niles Samson on the mission of New Hope.

In the early Pendulum War-era, shorty after the discovery of the Lightmass Process, the Coalition of Ordered Governments discovered that Imulsion caused adverse health effects in humans, namely a fatal condition known as Rustlung. Unknown to scientists at the time, Imulsion was a parasitic life-form that mutated and would eventually possess the host. Those most afflicted were the miners of Imulsion and their children. Due to possible economic and political ramifications if the public learned of health issues related to Imulsion mining and usage, the Coalition, under the Monroe Administration, opened the New Hope Research Facility to house and study the afflicted children of Imulsion miners to find a cure for Rustlung. The facility was put under the supervision of geneticist Dr. Niles Samson.

Doctor Niles Samson then began studying the progression of Rustlung by injecting children with doses of Imulsion. While most of the children continued to suffer and perish from Rustlung, a child named Myrrah showed not only immunity to Imulsion, but positive cellular regeneration to it, aging at 50% the rate of a normal human child. Niles hoped to replicate Myrrah's immunity in the other children, but failed. Niles then looked to indigenous creatures of the Hollow, who he believed had immunity to Imulsion due to their proximity. Cross-species genetic experimentation began, with the children being given the DNA of Hollow creatures. However, this mutated the children and turned them into a new type of hybrid species known as Sires.

The Sires were difficult to control and resulted in attacks on the staff at New Hope, prompting departures and information leaks. Once the Chairman Monroe became aware of the unethical experimentation at New Hope, he ordered the facility shut down and indictment of Dr. Niles Samson and all involved with New Hope. Before the facility was shut down, however, a fringe political group within the Coalition believed in Niles' work and offered to relocate him, his staff, and his subjects to a private, hidden facility in Mount Kadar, where he could continue his work without impeding ethics or bureaucracy. Niles then relocated his staff, several of his subjects, and Myrrah to the secret facility in Mount Kadar.

Mount Kadar LaboratoryEdit

"In our previous facility, we had problems with genetic stability. The Sires were... distempered. And sterile. A problem, for obvious reasons. But the Locust were different. Highly controllable. The perfect soldiers. And blessedly able to reproduce."
"What made them different?"
"Their cells. You see, the Imulsion miners' children provided a marvelous genetic repository... as did the indigenous creatures of the Hollow.
—Dr. Niles Samson explaining to Cpl. Kait Diaz the creation of the Locust Horde.

At the facility, Niles continued his work by fertilizing Myrrah's embryonic stem cells with the DNA of the Sires . Eventually, the first Drone of the Locust Horde was created. It was discovered that by using Myrrah's stem cells, a Hivemind was created among the Locust that could be controlled by Myrrah, as the Locust could not properly function without a "queen." To amplify the results, the scientists used Myrrah's stems cells and Sire DNA to create the Matriarch, the first Berserker. By connecting Myrrah to the Matriarch, she was easily able to control the Locust. In time, Myrrah came to regard the Drones as her children. Myrrah then had relations with geneticist Dr. Torres and conceived a human child, Reyna.

Reyna inherited Myrrah's psychomagnetic link to the Locust and was also under observation by the facility. Dr. Torres, however, became disillusioned with the work they were doing and escaped the facility with Reyna. Unable to recapture Reyna, Niles lied to Myrrah that Reyna had died in the escape attempt. Distraught, Myrrah began to resent humans for killing her daughter and forcing them underground and imprisoned. Using her link to the Locust, Myrrah staged a rebellion and led the Locust to freedom by massacring the facility's staff, including Niles Samson. Myrrah then led her people deeper underground Mount Kadar and built their own civilization, Nexus, and a society with its own language, religion, culture, military, and government.

Lambent WarEdit

Seven years before E-Day, Imulsion started evolving in the Hollows. Exposure to this Imulsion caused mutating creatures known as the Lambent that started fighting the Locust Horde deep in the Hollows, forcing them from their homes.

Enlisting Human AidEdit

Queen Myrrah desperately entered into a pact with Adam Fenix. If Adam Fenix could find a way to stop Imulsion from spreading, saving the Locust race, they would not have to invade the surface in order to survive.[10]

Unfortunately, Adam Fenix could not find a way to stop the Lambent in time because the Pendulum Wars was still raging on the surface. Adam used the last five years to finally create the Hammer of Dawn and end the Pendulum Wars between the COG and UIR. Before the peace treaty between the two Seran alliances was signed, Adam reflected on his pact with the Locust Queen hoping that she would not invade the surface.[11]

Locust WarEdit

Main article: Locust War

Emergence DayEdit

""For a time, the humans of Sera knew the illusion of peace... until Emergence Day. At that moment, our people broke free from our subterranean, erupting into the domain of these ground walkers, and wiping out whole cities. We fought and killed the humans on their fine boulevards, in their homes, on their battlefields."
Queen Myrrah explaining Emergence Day.[12]
Human-locust war

Six weeks after the Pendulum Wars ended, the Locust Horde invaded the surface, attacking all major cities and slaughtering billions in the first day. In the early hours of confusion, the COG viewed it as a massive UIR attack or the Gorasni attacking. Only after Chairman Dalyell's announcement that the attackers are subterranean in nature, the Seran people discovered that they are not the only intelligent species on the planet.

The Locust Horde easily overwhelmed the COG on E-Day and advanced from their captured cities, moving from one city to another only leaving destruction. The war against the humans allowed the Locust to advance their technology and war effort by using stolen human technology and equipment.

Occupation of SeraEdit

Six weeks after E-Day, the Locust general that led E-Day, General Karn led a massive assault on Halvo Bay. Kilo Squad led by Lieutenant Damon S. Baird attempted to stop him with the Lightmass Missile in the hopes that killing him would stop the Locust, but failed though they killed hundreds of Locust with the Missile and in their efforts to fire it. After a fierce fight with Karn and his mount Shibboleth, both are killed and the Locust lost their military leader. However, this was a minor victory as the Locust who still had High-General RAAM and Skorge around at this point continued on their mission to destroy humanity.

Hammer of Dawn CounterattackEdit

By 1 A.E., the Locust Horde was able to defeat the COG, but the humans used the Hammer of Dawn, destroying 90% of the surface and killing everything trapped on the surface within the blast zones. The Locust survived the Hammer, but are not able to accomplish a swift victory like they hoped.

Push for EphyraEdit

"Cut off the head of the snake and the body dies. We will win this war. It's only a matter of time."
—Queen Myrrah describing their new strategy.

With the COG's almost apocalyptic effort in using the Hammer of Dawn to potentially destroy some of the Locust Horde's forces, the Horde returned to continue the war. Having caught humanity off-guard and having slaughtered a vast number of the human population during the first five years of the war, they enjoyed the advantage of sheer numbers. With many hundreds of thousands, if not millions of the most battle-hardened Gears in the COG Army having been killed in the initial attack, the COG was forced to recruit the young and the imprisoned from the infirmary to try to hold off the advancing Horde off. As a result, not only did the Locust also benefit from an advantage in quantity of troops, but in the average quality of soldiers as well. As a result, the war went horribly for humanity, but went exceptionally well for the Locust who seized Landown in 5 A.E. during the Winter of Sorrow[13] and the COG capital of Ephyra in 10 A.E.

Fall of EphyraEdit

It was during the fall of Ephyra that the Locust supposedly killed the COG's most prominent scientist, Adam Fenix, the father of Marcus Fenix.[14]

Lightmass OffensiveEdit

In 14 A.E., Col.Victor Hoffman, the highest-ranking COG military leader directly underneath Chairman Richard Prescott devised a plan to win the war once and for all. The squads of Gears are deployed in what was known as the Lightmass Offensive across Ephyra City. Though many suffered from heavy, if not total, casualty rates, a single squad of hard-bitten veterans of the war was able to break through the Locust and deploy a device known as the Resonator, a sonic-mapper that was supposed to map the tunnel networks of the Hollow out.

The device was severely limited in its capabilities, barely mapping even a fraction of the network. Not all was lost as Delta-One was able to find a new data source, located in East Barricade that provided a much more sufficient geo-mapping of the Hollow. Upon securing the data, the squad was deployed to Timgad East to retake control of the captured Tyro Pillar which was a train which held the Lightmass Bomb. Delta was able to defeat General RAAM, the leader of the Locust Army as well as his forces aboard the train and deploy the Lightmass Bomb. This act resulted in the destruction of the entire Outer Hollow, causing incredibly high casualties to the Locust Horde and the near-complete annihilation of the entire population of the Kryll.[15][16]


The new Locust army of A.E 15.

The Return of the HordeEdit

Despite the Human's best efforts, the Locust proved incredibly persistent, even in the face of the most powerful weapons of mass destruction in history being delivered right onto their doorstep. With Skorge (Who was personally picked by RAAM to be his successor) appointed as the New High-General of the Horde, The Locust continued to mobilize and rebuild their forces, determined to break the back of humanity.[17] Bolstered by the awakening of their deity, the Riftworm, the Horde launched a major counter-offensive across Jacinto Plateau by attacking the city of Jilane and butchering the entire population ( A small group of renegades), depriving the COG of another breeding farm.

They proceeded to use the Riftworm to sink several cities surrounding Jacinto City and destroy several COG military bases.[18] Across the Plateau, the COG suffered from heavy casualties, mainly in the Pirnah Badlands and in several failed search-and-rescue missions in Tollen and Montevado. The Horde was also able to force the COG to abandon North Gate Agricultural Depot. However, this was just a precursor to the Siege of Jacinto which forced the COG's hand into retaliating with a mobilization on the scale that was not seen since 1.AE. However, most of these Locust attacks are done out of desperation. Throughout the entire war with humanity, the Locust was also fighting the Lambent and they are losing ground in the Hollow at an alarming rate.

Operation: Hollow StormEdit

After months of fighting across Jacinto Plateau, the Horde was able to lay direct siege to Jacinto City itself, having cut a great amount of its water and food supplies off. The Horde made its first incursions by attacking Pomeroy Depot and Jacinto Med, though it was a total disaster for the Locust who ended up having to make a hasty retreat. Nevertheless, the attacks on the last stronghold of humanity showed the COG how truly desperate that their situation was. Their backs are against the wall,\ and they had no choice, but to launch a desperate all-out attack on the Locust stronghold.

It was a high-risk maneuver. The odds of a payoff are understandably low and in the likely event that it should fail, it would leave Jacinto utterly and totally defenseless in case of a Locust counterattack, but if it succeeded, it could buy humanity time to regain its footing if not end the war entirely. And a massive fleet of Assault Derricks, King Ravens and Centaurs converged on the Locust-held city of Landown which was the perfect spot to launch a massive grindlift assault right into the heart of the Hollow.

The attack did not quite go as planned for either side. The Locust who had their backs against the wall themselves in regards to their conflict with the Lambent are preparing a final assault on Jacinto in an attempt to take the city and sink it to flood their old home with seawater to kill the Lambent once and for all. For the COG's part, during the initial assault, they found themselves attacking little more than staging areas and outposts rather than the heart of the homeland of the Locust, but Delta Squad managed to kill the Riftworm preventing that method of attack from working again.

However, they are able to pinpoint Nexus, the center of all Locust civilization and in their own desperate bid to annihilate their foes, they did exactly what the Locust are trying to do: They sunk their own city in order to wipe their foe out, but before the Locust are prepared for it, resulting in much of the Locust forces being annihilated. Queen Myrrah's fate was left unknown as she escaped from Nexus before the sinking, but Skorge, the new leader of the Locust Army was killed when Delta Squad destroyed his Hydra outside Jacinto.


The Horde 18 months after the fall of Jacinto

Lambent PandemicEdit

Rebuilding the HordeEdit

"You humans! Why do you think your lives are worth more than ours? Don't you realize who we are? Don't you recognize all your most admirable qualities in us? Oh yes... we are genocidal monsters! Just like you!"
—Queen Myrrah of the Locust Horde, arguing with Marcus Fenix during their final confrontation.[19]

Only hours after the sinking of Jacinto, the Locust stragglers were spotted around Port Farrall, leading to multiple battles throughout the city. The continuous fighting eventually forced the COG to look for a new home. Eighteen months after Operation Hollow Storm, the Horde reorganized on the surface of Sera, but was a shadow of its former power. In addition, with Queen Myrrah missing for a long period of time, the Locust Horde was leaderless, causing some of the Horde to degenerate into a feral state, becoming the Savage Locust.

Taking AzuraEdit

The others acted as the Queen's Guard under Myrrah. The Locust captured the island of Azura, the last remaining COG stronghold where the COGs elite scientists are kept safe in the First Battle of Azura and captured Adam Fenix who was working on a weapon against the Lambent. Adam was capable of destroying the Lambent and Imulsion, but it would also destroy the Horde so Myrrah had Adam work on refining it so it would only affect the Lambent.

Victory DayEdit

The Savage Locust and the Queen's Guard had multiple battles with the COG, attempting to prevent the COG from reaching and retaking Azura, but failed and engaged in the Second Battle of Azura with the COG, the Gorasni and the Lambent. Myrrah and her Tempest directly attacked the human forces, attempting to keep Adam from activating his weapon, but are defeated by the Hammer of Dawn. After the weapon killed Adam, Myrrah emerged and was killed by Marcus Fenix with Dominic Santiago's commando knife and the weapon killed all of the Lambent as it was meant to as well as all of the Locust, making the species extinct. After the Lambent invasion, the COG would dispose of the remains of any Locust that they found into mass graves across Sera.[20]

Swarm WarEdit

"You see, what you don’t realize – what none of you realize – is that my children will never die. They have been designed to withstand generational conflict. They may withdraw, they may hibernate, but they will always return. We have seen to that."
—Dr. Niles Samson revealing that he designed the Locust to always adapt and survive as an immortal species.

Unknown to the survivors of the COG, the Locust are not rendered extinct. Only the Lambent was. Instead, the Imulsion Countermeasure Weapon forced a genetic evolution within them, causing the Locust 'corpses' to become covered in impenetrable crystalline shells while the Lambent are vaporized into nothing. Unable to dispose of the bodies, the survivors of the COG dumped the cocoons into highly classified locations across Sera, most notably the osmium mine beneath Fort Reval and the gorge beneath Tollen Dam. For twenty-five years, there was peace until shortly before the twenty-fifth anniversary of the end of the Locust War, the Locust began to re-emerge as The Swarm. The Swarm War began shortly after as the altered Locust, now seemingly imbued with higher intelligence and improved, stronger bodies took command of the lesser mutations, all rallied under the banner of the Speaker. From here, the Swarm began to grow its numbers by abducting vast amounts of Outsiders and several groups of COG citizens, allowing them to grow a large army in a short period of time.

Following the events of the battle of Tollen Dam, the Swarm still posed a threat to humanity.

Society and CultureEdit

The Locust Horde was a matriarchal society divided into multiple castes. The Locust Hordes' hierarchy, society and social class system was very similar to and could be compared with a bee hive. The Queen was the head of the entire Locust Horde and led it in advancement, improvement and steadily increasing its size and power. The only known class was the Kantus monks led by Skorge until 15 A.E. The Kantus monks followed a strict religious code. The lower classes of the Horde are willing to die for the Queen. However, there are field officers that are of higher intelligence, strength, intellect and power than the standard foot soldiers and led the Hordes' military into battle. This class was an organization known as the Theron Guard. There was also the Palace Guards whose members are the defensive counterpart to the members of the Theron Guard. The officers of the Palace Guard are the most powerful, decorated and accomplished Drones in the Hordes' military and are charged with the defense of the Queen's Palace and of Queen Myrrah herself.


Queen MyrrahEdit

Queen myrrah

The Queen

Main article: Queen Myrrah

Queen Myrrah was the enigmatic leader and creator of the Locust Horde. Born to an Imulsion miner in Tyrus, Myrrah was born with genetic immunity to Imulsion and was resistant to Rustlung and Lambency. She was brought to the New Hope Research Facility to help replicate her immunity in other children infected with Rustlung. When that failed, geneticist Dr. Niles Samson mutated the children with the DNA of indigenous creatures of the Hollow, transforming them into Sires. By utilizing Myrrah's embryonic stem cells and Sire DNA, the Locust Horde was born. However, due to the Locust's longing for independence and the kidnapping of Myrrah's daughter, Reyna, she became Queen of the Locust Horde and led the Locust to slaughter the scientists and gain independence. Over the years, Queen Myrrah continued to grow her people. Though she was never present on the battlefield, she was the undisputed leader of the Locust Army and the top of the Locust hierarchy, leading the Horde with ruthless tactics to exterminate all threats to the Locust Horde, both Human and Lambent. However, following the sinking of Jacinto, Queen Myrrah went missing, leaving a majority of the Horde leaderless and disorganized. She was killed in the Battle of Pinnacle Tower by Sgt. Marcus Fenix, who stabbed her in the chest with Cpl. Dominic Santiago's commando knife. However, her consciousness survived in the Locust hivemind and was able to possess her daughter, Reyna, becoming the Queen of the Swarm, an evolved form of the Locust.

Uzil RAAMEdit

RAAM TyroPillar UE

The High General

Main article: RAAM

Uzil RAAM was the brutal and powerful Locust High General of the Locust Army for most of the Locust War. He commanded and led the entire Locust military into battle and was second to Queen Myrrah. RAAM spent only one year as a Maag of the Locust Army and arose to the rank of Theron Guard, but was then exiled from the Guard and made Vold. Vold RAAM was promoted to Uzil after defending the Locust from destructive Lambent attacks and revealing that he shared the Queen's vision of invading the surface to escape the Lambent, a vision that Uzil Sraak lacked. Uzil RAAM personally designed the attacks of what would be known as Emergence Day. On the battlefield, Uzil RAAM was usually armed with a Troika Heavy Machine Gun, a his serrated blade, and a shield of Kryll under his command. His strategy for defeating the humans was to find and execute military leaders, leaving the soldiers defenseless. He led the Locust Army for fourteen years until he was killed by Sgt. Marcus Fenix and Cpl. Dominic Santiago while on the Tyro Pillar which carried the Lightmass Bomb, trying to prevent the weapon from being detonated to save the Locust and the Outer Hollow.

Uzil SraakEdit

Main article: Sraak

Uzil Sraak was the High General of the Locust Army before the Locust War. He led the Locust Army during most of the Lambent War, but lacked the foresight RAAM and Myrrah shared. Instead, Sraak believed the Hollows were theirs by birthright, and the Lambent had to be exterminated and the Locust reclaim their home rather than abandon it. He also held prejudices towards those who were created as the Locust and not the true descendants of the Sires. When Vold RAAM convinced Queen Myrrah that they shared the same vision of invading the surface, exterminating the humans, and escaping the Lambent, Queen Myrrah demoted Uzil Sraak to Vold. On Emergence Day, during the Battle of Jannermont, Vold Sraak made an attempt on Uzil RAAM's life. Vold Sraak was then executed by Uzil RAAM for treachery, via Theron Guard shooting squad.

Zamil KarnEdit


The General

Main article: Karn

Zamil Karn was a General of the Locust Army during the first months of the Locust War. He was a field commander known for his intelligent strategies and planning. Originally considered an outcast by his Locust brethren due to his malformed body, Vold Karn became a high-ranking general in the Horde due to his tactical intelligence, mastering of the creature known as the Shibboleth, and assistance in helping his comrade, Vold RAAM, convince the Queen to invade the surface. Vold RAAM was promoted to Uzil and promoted Vold Karn to Zamil and was ordered to lead Blights into the Republic of Gorasnaya when they would invade the surface. Zamil Karn was successful during Emergence Day when he led the Fall of Gorasnaya, but perished at the hands of Col. Ezra P. Loomis during the Destruction of Halvo Bay after the Gears of Kilo Squad killed his Shibboleth at the Plaza for the Tyran Dead.

Ketor SkorgeEdit

Skorge Crouch

The High Priest

Main article: Skorge

Ketor Skorge was the High Priest of the Locust Horde for the majority of the Locust War. During the Lambent War, Kantus Skorge was exiled by Ketor Vrol for his prophetic visions of the Locust losing the war, which was seen as blasphemous. Afterwards, he fought by Vold RAAM's side and was instrumental helping persuade Queen Myrrah to invade the surface. Vold RAAM was promoted to Uzil and Skorge was welcomed back into the Kantus as Ketor. Ketor Skorge then assisted Uzil RAAM during the Emergence Day. Uzil RAAM requested that Ketor Skorge take his place when his death would occur. In 14 A.E., after Uzil RAAM's demise, Ketor Skorge took the position of the Horde's highest military leader. After the detonation of the Lightmass Bomb, the Riftworm awoke and Ketor Skorge was able to control it, using it to sink entire COG cities on the surface in order to weaken Jacinto's base, causing the city to sink and flood the Hollow, killing the Lambent. On the battlefield, Ketor Skorge was usually armed with his Dual Chainsaw Staff, Gorgon Submachine Gun, Ink Grenades, and could summon Tickers. Ketor Skorge was killed when Sgt. Marcus Fenix killed his personal Hydra mount, causing him to fall to his death.

The Locust Horde's religion revolved around the worship of worms. The Riftworms and Rockworms are viewed as highly significant creatures in the Locust's religious texts. The Trinity of Worms was the symbol and title of the Locust Horde's religion, symbolizing and revering the Riftworms as Gods.[21] The Kantus monks are the religious priests of the Locust and are a caste level. The scrolls of the Kantus contained verses and mantras explaining how to communicate with Rockworms[22] with the Rulers of Nexus Plates tablet being the Locust's main religious tome which told the history of the Hollows, explaining how the Riftworms burrowed underground and created the vast underground network and left their waste behind which fertilized the soil of the surface of Sera.[23] According to the High Priests of the Locust Horde, Sires are also revered as holy figures. They are seen as divine "incubators" evolved from the Riftworms. The leader of the Locust Horde's religious caste was High Priest Skorge.[9]

Rulers of Nexus PlatesEdit

"When man [to] The Worms [said] what is your name? The Worms answer, My name is Horde. For we are many with vengeance."
—Translation of a part of the Rulers of Nexus Plates.
Locusttablets--article image

The Rulers of Nexus Plates

The Rulers of Nexus Plates, also referred to as the Locust Tablets was the Locust Hordes' main religious book. This tome contained information on the history of the Hollow and of the Riftworms. The story of the Rulers of Nexus Plates told how the Riftworms burrowed under Sera's surface and dug around underneath, creating the Hollows. When the Riftworms left their waste behind, the waste fertilized the soil, creating and sustaining life in the Hollows and on the surface of Sera. Another part of the tome told how the Lightmass Bomb awoke one of the Riftworms and killed most if not all of the Kryll and how the Riftworm was used to sink the cities of Tollen, Montevado and Ilima.[24][23]

Trinity of Worms ArtifactEdit

"The Queen makes strong Drones, Drones secure Nexus, Nexus covers the Queen."
—Translation of the Locust runes on the Trinity of Worms Artifact.
Trinity of Worms artifact

The Trinity of Worms artifact.

The Trinity of Worms was the symbol and title of the Locust Horde's religion, revering the Riftworms as gods. The Trinity of Worms explained how the Queen made strong Drones, how the Drones protected Nexus and how Nexus covered the Queen. The Trinity of Worms also told the tale about how the Riftworms burrowed through Sera's surface and went underground, creating the massive underground caverns which would be known as Hollows. The Riftworms also left their wastes behind which fertilized the soil of Sera, bringing life to the Hollows and the surface of Sera.[21]

Kantus ScrollsEdit

"When man [to] the Worms [said] what is your name? The Worms answer, My name is "Horde" for we are many with The Trinity of Worms."
—The translation of the Kantus Scrolls.
Kantus Scrolls1

The Kantus Scrolls.

The Kantus Scrolls are ancient Kantus writings that are the code of the Kantus. The Scrolls contained verses and mantras that explained how to communicate with Riftworms and Rockworms. Some copies of the Kantus Scrolls are used with Human skin fitted in between rollers with the religious text written on them with ink.[22]


Main article: Locust Runes

The Locust Alphabet

The Locust had their own writing system, which was referred to as Locust Runes. The Locust Runes were based on a lexigram used by the scientists of the Mount Kadar Laboratory to communicate with the original generation of Locust. The system consisted of symbols which represented individual letters and ideograms that represented full words based on the Tyran language. The writing system's alphabet contained 26 symbols for 26 letters. The numbering system contained 10 numbers that was represented by 10 symbols.

There was also a computerized version of the Locust writing system which could be seen on the Locust computer terminals. These symbols are cleaner and more identifiable than the handwritten symbols. The most notable examples of the computerized Locust alphabet are found on the Locust computer terminals[25][26] and the Locust Invasion Map.[27]

As for the relationship with human languages and writing systems, there are 21 confirmed ideograms that represented Tyran words. As a spoken language, the official language of the Locust Horde was also Tyran. However, the Locust Horde created several words in their own languages. Many of them were associated with a Tyran word, but when directly translated is meant as something else. For example, the rankings in the Locust Army such as Maag, Vurl, Vold, Krav, Zamil, and Uzil are meant as Private, Sergeant, Lieutenant, Captain, General, and High General. However, the direct translations are "virgin", "dirty", "battered", "bloodied", "gored", and "unbroken."

Calendar SystemEdit

Translation of symbols clockwise: Queen, Fire, Drone, Leviathan, Danger, Nemacyst, Imulsion, Water, Human, Kryll, Secure, Seeder.

The Locust had their own calendar system which was based on Imulsion flowing through the Hollows. Within the calendar system, there are 12 seasons, each with opposites.[28]

  • Queen-Imulsion
  • Fire-Water
  • Drone-Human
  • Leviathan-Kryll
  • Danger-Secure
  • Nemacyst-Seeder

Each full rotation of the calendar was referred to as a "cycle" and matched that of the regular Seran year. One cycle of the Locust calendar was also one year of the Seran calendar.

Standards and SymbolsEdit

Queen's Symbol

The Queen's Symbol.

The Locust Horde had many objects to represent their society, culture and religion as well as their people. Queen Myrrah had her own symbol which all members of her Guard always carried with them. The Savage Locust appeared to have rejected this symbol.[29]

The symbol of the Locust Horde's religion was the Trinity of Worms which told the history of the Riftworms and the creation of the Hollow as well as how the Lightmass Bomb killed most if not all of the Kryll and awoke one of the Riftworms which was used to sink the three cities surrounding Jacinto City. The Trinity of Worms was represented by physical artifacts, a medium-sized object with a glowing triangle directly in the middle of the artifact with the three curved prongs designed to represent the worms of the Hollow. The main verse of the Trinity of Worms was written on the artifact with different parts of the verse spread out on the three prongs.[21]

The Locust also produced jewelry such as emblems that are referred to just as the "Locust Emblem." Damon S. Baird, in an intelligence report theorized that the Locust either kept track of their fallen soldiers like the COG did or they just had a bad taste in jewelry.[30] The Locust also produced human finger necklaces.[31]

Architecture and InfrastructureEdit


Nexus, the Capital City of the Locust Horde

The Locust Horde's infrastructure was largely composed of what appeared to be stone and brick. Some of the structures that are built included Reaver Pens, torture sections for the captured Humans, aqueduct systems, dams, bridges and roads.

Some of the most notable structures that the Locust Horde built was the Palace, the capital building in Nexus and the Highway which was the central highway of Nexus.[9]

Military Tactics and StrategiesEdit

The military tactics and strategies of the Locust Horde originally involved just defending their cities against the Lambent after the Locust discovered them with some of their forces strategically stationed in and around Nexus. The defense of Nexus was strategically planned as the Locust Horde was determined not to lose their capital city. One copy of their defensive plans for Nexus showed the palace with Queen Myrrah at the center being protected by Drones who surrounded the palace. Imulsion was all around Nexus and the Lambent forces coming from one side of Nexus.[32]

At an unknown time when the Locust hierarchy made the decision to invade the surface of Sera, their tactics and strategies now had to include offensive plans. When the Horde launched their invasion of the surface of Sera on what was to be known as Emergence Day, the Locust poured huge numbers of the forces onto the surface, coordinating their invasion to take place in every single major city on the surface of Sera. During Emergence Day, the Locust Horde's military forces succeeded in a number of ways in dominating the Humans and crushing their military forces. On Emergence Day, the Locust managed to kill 1/4 of the total human population which dealt a severe blow to the Humans.[8] They gathered all available civilian and military hardware from the cities that they invaded. The supplies and hardware are collected and the auto parts are salvaged from the wreckage.

After the Lightmass Offensive in 14 A.E., during which the Humans launched a Lightmass Bomb into the Hollows, Queen Myrrah announced to her Horde: "Cut the head of the snake off and the body died. We would win this war. It was only a matter of time." A new strategy was in place. The Locust Horde would try to take the leaders and command system of the remaining Humans down. If they succeeded, the rest of the Humans would fall and the Locust Horde would win the war and Sera would be theirs.[33]

Despite the Drone's tendency to blindly charge into battle, the Locust are far from mindless in battle, employing cunning and resourcefulness to win just as much as sheer brutality and mercilessness. The assumption that the Locust are little more than mindless beasts greatly hindered the COG's initial efforts.

While the individual Drone's intelligence was questionable, prominent Locust commanders such as Karn, General RAAM and Skorge displayed great cunning and strategy. The Gears in the field often attributed unexpected and surprising tactics from Locust to the presence of a smarter commander pushing them such as the use of smoke grenades and grappling hooks by RAAM's forces to assault Zeta-Six's position during the Ilima evacuation.

The Locust most infamous tactic was the use of Emergence Holes or E-Holes to deliver their forces directly into battle. The E-Holes in addition to quickly delivering their forces had a heavy psychological affect on enemies since they allowed the Locust to attack nearly anywhere at any time without warning.

Foot SoldiersEdit


Main article: Drones

Bred for genocide

The Drones appeared to be the common race among the Locust Horde. They are larger than humans and had chalky white skin with gray, scale-like patches that most likely are hardened to protect them from minor damage. They are bred in the Hollow to be bloodthirsty fighters, supposedly by the Queen herself. When ordered, the Drones would throw their lives away by the hundreds to kill a single entrenched Gear. They are often observed crawling out of "emergence holes" which the Locust used as bridges between the underground and the surface world. The Drones regularly carried basic infantry tactics out of flanking, dominating the terrain and setting ambushes up as well as more advanced tactics, suggesting that the Drones themselves are intelligent, independent creatures rather than dim-witted, single-minded brutes or some combination. Almost fearless, they knew little in the way of self-preservation and almost never retreat, though they had little need to, considering their vast numbers. The Drones often referred to the humans as "Groundwalkers" or "Hominids". They would usually wield the Hammerburst assault rifle or Hammerburst II battle rifle, the ubiquitous standard infantry weapons of the Locust. The Grenadiers are specialized Locust drones that wielded the Gnasher Shotgun with deadly accuracy and precision. They preferred the brute force of the Gnasher over that of the Hammerburst variants. Trained to relentlessly stalk and engage humanity, they are the powerhouses of the Locust Horde.

Non-canon classes:


—Theron in combat.

The elite Therons are easily distinguishable from the standard Drones thanks to the long, leather-like cloaks and metallic masks that they wore in addition to ornate armor which was apparently superior to the generic Drone armor. Their sibilant voices are known to scare the Gears into fleeing though their speech was also hard to understand or even notice thanks to being so raspy and mistaken for the wind. The Therons are stronger, faster and far more intelligent than an average Drone. They mostly wielded deadly Torque Bows or the equally deadly lancer. Because of their increased intelligence, strength and speed, the Therons are usually assigned to officer roles, leading smaller groups of Locust forces into battle.

There are many classes of Therons, each with minor differences:


Main article: Boomers 

A standard Boomer

The Boomers are huge, markedly less intelligent Locust. While the normal Boomers used the Boomshot, the Boomer subclasses are known to use other weapons. Compared to their smaller brethren, the Boomers are very durable, capable of taking a shot to the head from a strong weapon and surviving while their smaller brethren would die instantly from a headshot. When deployed into battle, the Boomers would charge into the frontlines and attack the nearby enemies, unless directed by a superior commander which they would follow their instructions.

The Boomers and their subclasses are very predictable in battle as they yelled phrases out that went according to their actions (A Boomer would say "BOOM!" before firing), allowing the Gears to quickly set tactics up against them.

There are several different combat variants of the standard Boomer:



The Kantus Priest.

Main article: Kantus

The Kantus are Locust priests and the religious leadership of the Horde and are led by the Locust High Priest, Skorge. They stood 7 feet and had leathery white flesh. They are often heard chanting which was used to communicate with the other Locust in order to direct attacks, control the Hollow creatures, but could also revive the downed Locust soldiers in a seemingly mystical fashion.

They are extremely agile and are seen rolling to one side to avoid the gunfire. Their main weapons in battle are the Gorgon Burst Pistol and the Ink Grenade.

There was a combat variant of the standard Kantus: The Armored Kantus which only appeared during the Lambent Pandemic. Compared to the normal Kantus, the Armored Kantus dual-wielded Gorgon Pistols and are clad in spiky onyx armor which gave them increased resistance against the bullet attacks.


Main article: Berserkers

A render of a Berserker

The Berserkers are monstrous female Locust. They are blind and relied on smell and sound to navigate and locate the enemies. Possessing enormous physical strength, these Locust could tear their foes from limb from limb and could gain enough momentum when running to smash through a solid stone wall, able to kill the Gears in a similar fashion to ramming them with a vehicle by running into them at high speed.

Vicious and bloodthirsty even by Locust standards, they are known to kill the other Locust Drones just for getting too close and anything that irritated them. Any Gear that fought a Berserker would have to be quick with their feet to defeat her and the only known effective way to kill one was to lure it outside and blast it with the Hammer of Dawn or by setting it on fire. This weakened the Berserker's hide meaning that it became susceptible to gunfire until the hide cooled and rehardened. Though the Berserkers are seen killed through concentrated small arms fire, it was easier to kill a Berserker with flames.


Main article: Rager

Another type of Locust that was similar to the Berserkers are called Ragers. When not enraged, the Ragers are similar to a normal Drone. When angered, however, the Ragers are known to transform, giving them temporary strength similar to that of a Berserker. The Ragers are thought wiped out early in the Locust War, sometime after the Destruction of Halvo Bay which occurred in 0 A.E. However, they survived and briefly reemerged as part of the Savage Locust in Halvo Bay in 17 A.E.
