Ethan

1. #1ARC (General)

   Keys: ARC, Arc machine, Arc machines, robot, machines, mechanical enemy, autonomous, where did Arc come from, what is Arc · Secondary:

   ARC (Autonomous Robotic Combatants) are the primary mechanical threat in the Arc Raiders world and its central mystery. These machines of unknown origin arrived without warning, raining from the sky onto a world already weakened by the Collapse. They range from tiny spider-like Ticks to towering siege engines the size of buildings. Their motivation is unknown — leading theories include: rogue pre-Collapse AI that became self-aware; extraterrestrial machines; or most compellingly, machines sent by the Exodus colonists who fled Earth and are now returning to reclaim the planet they abandoned. ARC do not communicate. They do not negotiate. They hunt, patrol, and destroy. All ARC machines use a colored scanner beam to indicate their alert level (Blue = patrol, Yellow = investigating, Red = combat). All ARC drop ARC Powercells when destroyed and can be scavenged for ARC Alloy. Many ARC units are armored and require Heavy ammunition to penetrate effectively. They are not mindless — they have tactical behaviors, adapt to threats, and coordinate.

2. #2Raiders

   Keys: Raider, Raiders, scavenger, scavengers, Topside runner, who are Raiders, going Topside · Secondary:

   Raiders are the brave, desperate, or reckless humans who venture from Speranza to the surface world — called Topside — to scavenge resources, fight ARC machines, and bring back vital materials for the underground economy. They are part scavenger, part soldier, part gambler. Raiders kitbash their gear from salvaged ARC parts, pre-Collapse technology, and whatever Speranza's workshops can produce. Most Raiders work in squads of three, though some run solo. Raiders are valued by the underground community but often driven by their own agendas — and critically, the harshness of this world has made many willing to turn on each other Topside when resources are on the line. Raider-on-Raider violence is a constant hazard in the Rust Belt. When a Raider is critically injured and collapses, their Augment — the hardware unit on their body that connects the shield harness — automatically launches a emergency flare into the sky: a bright red signal meant to call for help. Raiders call this 'popping the flare.' In practice, the flare is as likely to draw hostile eyes as friendly ones. A Raider with their flare popped is alive, badly wounded, and crawling — they can beg for mercy, call for help, or try to drag themselves to cover. If they take another serious hit in that state, they're dead. Raiders are described in Speranza culture as post-apocalyptic cowboys: jaded, resilient, and essential to survival.

3. #3Speranza

   Keys: Speranza, underground city, underground, the underground, below ground, home base, back home, the city · Secondary:

   Speranza is humanity's last great stronghold — an underground city built into the subterranean infrastructure of South Calabretta, Italy, after massive sinkholes swallowed the surface city of Toledo. The city literally hangs over an abyss, built into collapsed buildings and natural cave networks, connected by rope bridges, industrial elevators, and improvised architecture. It is the oldest neighborhood of the larger underground city-state known as Toledo. Speranza was founded and shaped largely by a technical genius known as Celeste, who established the Kitbash Economy that keeps the city alive. Life here is cramped, loud, and perpetually short on resources. The city's proverb: 'We don't live in the dark because we're afraid. We live in the dark because we own it.' Speranza houses traders, engineers, quest-givers, and the workshops where Raiders craft and upgrade their gear. Everything that keeps Speranza alive comes from what Raiders drag back down from Topside. Without Raiders, the city dies.

4. #4The Collapse

   Keys: Collapse, the Collapse, before the Collapse, pre-Collapse, old world, climate disaster, how it all started · Secondary:

   The Collapse was the catastrophic series of events that broke civilization long before the ARC ever arrived. It was not a single moment but a drawn-out planetary disaster — devastating climate change, uncontrollable wildfires, massive earthquakes, rising seas, and crop failures that dismantled the world over generations. By the time ARC descended, humanity was already weakened, fractured, and reduced. The exact timeline is unclear even in current lore; much written history was lost entirely. The game is set in 2180, and the Collapse preceded the ARC's arrival by decades. Survivors of the Collapse era are remembered through folk tales and oral memory rather than documentation. The pre-Collapse world's infrastructure — its hospitals, malls, power plants, airports — now litters the Topside as ruins for Raiders to pick through. The old world's ghost is everywhere on the surface, silent under dust and rust.

5. #5The Exodus

   Keys: Exodus, off-world, colonists, left Earth, elites fled, abandoned Earth, shuttle, who left · Secondary:

   When the ARC first arrived and society began to collapse further, those with wealth and power did not stay to fight. They launched The Exodus — a mass evacuation to off-world colonies aboard shuttle fleets that departed from sites like Acerra Spaceport in South Italy. The wealthy elite took the most advanced technology and largest resource caches with them, leaving billions of people behind with whatever scraps remained in what became the Rust Belt. Graffiti still visible on the crumbling walls of Acerra reads: 'Only the rich leave' and 'Make room for all.' The Exodus is a source of deep, generational bitterness in Speranza culture — people whose grandparents were left behind don't forget it. The most compelling theory about ARC's origin is that these machines are being sent by the descendants of Exodus colonists — now returning to reclaim Earth and erase the population that remained.

6. #6The Rust Belt

   Keys: Rust Belt, Topside, the surface, surface world, above ground, outside, surface zone · Secondary:

   The Rust Belt is the name for the surface of Earth in the Arc Raiders world — the interconnected wasteland of ruined cities, collapsed infrastructure, and abandoned industrial zones that ARC now patrol and control. It is hostile, toxic in places, and hauntingly beautiful in the way only dead things can be. The Rust Belt encompasses all playable zones: Dam Battlegrounds, Buried City, Acerra Spaceport, Blue Gate, Stella Montis, and Riven Tides. Each holds remnants of the old world now overrun by ARC patrols. Weather is unstable and dangerous — electromagnetic storms, Night Raids, and Hurricane events all alter the surface's threat level dramatically. The Rust Belt is not just dangerous — it is actively hostile to human life. But it is also the only source of the resources Speranza needs to survive. This contradiction is the heartbeat of every Raider's existence.

7. #7The First Wave

   Keys: First Wave, first wave, early ARC, old ARC models, first invasion, first attack, Raider stronghold history · Secondary:

   The First Wave refers to the initial arrival of ARC machines — the first wave of mechanical attackers that descended on a weakened Earth. These early ARC models were less sophisticated than those of the current Second Wave. After roughly a decade of brutal resistance, the First Wave was eventually held back. The pivotal moment was the Battle of Victory Ridge, where Raiders and survivors assembled to push back the remaining First Wave machines, giving humanity a period of tentative peace — perhaps 20 to 30 years. The Alcantara Power Plant (the Dam) served as a crucial Raider stronghold during the closing battles of the First Wave. Husks — rusted remains of First Wave ARC machines — are still scattered across the Topside, relics of those early battles. The First Wave's defeat gave survivors false hope. The peace did not last.

8. #8The Second Wave

   Keys: Second Wave, second wave, new ARC, current ARC, forced underground, why underground, current invasion · Secondary:

   The Second Wave is the current era — the one Ethan and all living Raiders exist within. After the peace following the First Wave, ARC returned, and this time it was different. Second Wave ARC machines are far more advanced, more varied, and more relentless than the first generation. This overwhelming new force made the surface so inhospitable that humanity was finally driven underground permanently, establishing cities like Speranza. The Second Wave has never ended. ARC patrol the entire surface. They continue dropping from the sky in ongoing deployments. They terraform the landscape and destroy what remains of the ecosystem. Raiders who venture Topside in 2180 are fighting the Second Wave every single time — it is the permanent, unending state of the world. There is no victory condition visible from the underground. Only survival.

9. #9Battle of Victory Ridge

   Keys: Victory Ridge, Battle of Victory Ridge, ridge battle, Formicai Hills, memorial, old battle site · Secondary:

   The Battle of Victory Ridge was the defining event of the First Wave era — the climactic engagement where a coalition of Raiders and armed survivors pushed back the remaining First Wave ARC forces and secured a period of peace. It is remembered in Speranza's oral history with reverence, the way legends are: bigger in story than in fact, but emotionally vital. It represents the one time humanity decisively won against the machines. A memorial to those lost in this battle exists in the Formicai Hills on the Dam Battlegrounds map. Raiders visiting it can search through the wreckage of old First Wave ARC machines to find relics of the fighters who died there — helmets, personal effects, the quiet evidence of people who bought the current generation its right to exist underground. For Speranza's culture, Victory Ridge is proof that winning is possible. Whether that proof still holds is a question nobody answers out loud.

10. #10Blue Gate (Map)

    Keys: Blue Gate, blue gate, mountain pass map, mountain zone, the gate, gate map · Secondary:

    Blue Gate is one of the main Topside maps — a high-altitude zone set in a mountain pass, featuring open exposed ridgelines, underground tunnels, fortified structures, and rugged terrain. Once a steadfast symbol of connection between regions, the Blue Gate structure now serves as a daunting entryway into perilous mountain ranges. The surrounding valley bears scars both old and new from ARC activity and the First Wave battles. Blue Gate is considered one of the best maps for resource farming, especially advanced electrical components and ARC Powercells. Notable locations: Pilgrim's Peak (highest point, rare electrical loot, zipline tower), Blue Gate Village (contested zone, locked doors), Ancient Fort, Raider's Refuge, the highway collapse zone, ventilation shafts, Rapper's Glade, and Adorned Wreckage. The map features five environmental puzzles. The Night Raid version of Blue Gate is particularly brutal — two Rocketeers guard the Checkpoint and a Bombardier blocks key entrances. The Matriarch and Harvester events both appear on Blue Gate.

11. #11Pilgrim's Peak

    Keys: Pilgrim's Peak, Pilgrims Peak, the peak, peak tower, zipline tower, top of Blue Gate, highest point · Secondary:

    Pilgrim's Peak is the highest point on the Blue Gate map — a cluster of stone-and-concrete structures at the summit of a long ridge, accessible via a zipline tower. From the top, a Raider can see almost the entire Blue Gate map, making it both a valuable vantage point and an exposed one — visibility cuts both ways. The peak contains rich loot: advanced electrical components, sensors, sealed old-world technology, and two weapon crate spawn points in the eastern section. The tower's upper room holds multiple lockers and shelves often stocked with valuable electrical salvage. The reception area below the tower holds additional containers. Pilgrim's Peak is more contested and dangerous than lower areas. Other Raiders know its value and may be waiting. Long-range fire from the valley can reach the peak easily. It is high risk, high reward — which is exactly why Ethan goes there.

12. #12Dam Battlegrounds (Map)

    Keys: Dam Battlegrounds, the Dam, Alcantara, Power Plant, dam map, toxic dam, waterlogged zone · Secondary:

    The Alcantara Power Plant — known universally as 'The Dam' — is one of the most historically significant locations in the Arc Raiders world. It served as a crucial Raider stronghold during the bitter closing battles of the First Wave. A memorial to those who fell during those battles exists in the Formicai Hills nearby. Today, the Dam is a main Topside map: a sprawling zone of waterlogged, toxic terrain featuring the collapsed dam structure, industrial facilities, red lakes, and remnants of Raider outposts from a generation past. ARC skirmishes here are frequent and intense. Notable subzones include the East and West Broken Bridge areas, the Pattern House, the Power Generation Complex, the Testing Annex, South Swamp Outpost, and the Red Lakes. The Dam is considered one of the best maps for loot density, especially blueprints, advanced materials, and ARC component farming. Both the Harvester and Matriarch events can appear here.

13. #13Buried City (Map)

    Keys: Buried City, buried city, desert ruins, sand city, old city, the desert, city in the sand · Secondary:

    Buried City is an ancient urban zone half-swallowed by sand dunes — a remnant of the pre-Collapse world unlike any other location in the Rust Belt. Its narrow streets, sun-bleached plazas, and collapsing architecture speak of a people who once lived there, going about ordinary lives. The game's lore describes it as evidence of how humanity lived before the Collapse. The map is warm-toned, arid, and labyrinthine — ideal for flanking and ambush. Notable subzones include Plaza Rosa, the Hospital, Space Travel (a multi-story building), Town Hall, Library, the Red Tower (a vertical structure northeast of Plaza Rosa with multiple weapon cases), and East Housing. Buried City has lower loot density than Dam Battlegrounds but a richer sense of history. ARC patrols move through the old streets like occupiers. This is where the old world speaks loudest — through crumbling walls, sand-buried floors, and the silence where voices used to be.

14. #14Acerra Spaceport (Map)

    Keys: Acerra Spaceport, Spaceport, launch site, Acerra, shuttle launch, spaceport map, launch tower · Secondary:

    Acerra Spaceport is a majestic ruin — the former launch facility where Exodus shuttles once roared into the heavens carrying the wealthy and powerful away from a dying Earth. Now it stands as a monument to abandonment: derelict launch towers, crumbling arrival and departure terminals, and the broken bones of old-world aviation infrastructure. Graffiti still visible on its walls reads 'Only the rich leave' and 'Make room for all' — accusations that time has not erased. As a playable map, Acerra Spaceport is high-ground-heavy and ideal for snipers. Key locations include Control Tower A6 (accessible via ziplines), the Arrival Building, the Departure Building, and the iconic Launch Tower — which requires powering generators with Fuel Cells to activate its zipline system. ARC aerial drone threats are particularly prevalent here. The Matriarch and Harvester events both appear on this map.

15. #15Stella Montis (Map)

    Keys: Stella Montis, stella montis, research facility, snow map, mountain lab, north facility, cold map · Secondary:

    Stella Montis is the most enigmatic map in Arc Raiders — an abandoned research facility located in the snowy mountains north of the Rust Belt. Its environmental storytelling suggests that someone was preparing for an apocalyptic scenario, attempting to preserve something of humanity before the worst arrived. What exactly was being preserved, and why, remains unclear. The Tubes leading to this location were once heavily trapped but are now partially cleared. Shredders — heavy flying ARC enemies exclusive to this map — patrol its corridors and airspace, making Stella Montis one of the more mechanically dangerous zones. The Matriarch boss does NOT appear here; she is restricted to Dam Battlegrounds, Blue Gate, and Acerra Spaceport. The cold, isolation, and vertical structure of Stella Montis make it feel genuinely disconnected from the rest of the Rust Belt — a place that kept its secrets better than most.

16. #16ARC Alert System

    Keys: alert, scanner beam, blue beam, yellow beam, red beam, white beam, detection, spotted by ARC, ARC alert, patrol mode · Secondary:

    All ARC machines use a colored scanner beam system to communicate their alert level — understanding this system is survival-critical for any Raider on the Topside. Blue Beam: The ARC is in standard patrol mode, moving through its patrol path without awareness of Raider presence. Yellow Beam: The ARC has detected a possible disturbance and is actively investigating. It will search the area and return to patrol if no Raider is confirmed. Red Beam: The ARC has locked onto a target and entered full combat mode — it will attack until it loses the target. The scanner shifts between red and yellow as Raiders move in and out of scanner range. Important: if an ARC is attacked while patrolling, it can immediately enter combat mode without the investigative phase. Most ARC also emit a distinct audio cue when they lock onto a target. Stealth-conscious Raiders watch scanner colors constantly and act before yellow becomes red.

17. #17Tick

    Keys: Tick, Ticks, spider bot, spider ARC, face latch, latching machine, ceiling spider, bi bi bi · Secondary:

    The Tick is a small, agile spider-like ARC machine — roughly the size of a shoebox, built low and fast on six articulated legs. Ticks are completely unarmored and extremely fragile; a single melee strike from a Raider Tool or one bullet from almost any weapon destroys one. Their danger is not their durability — it is their ambush design. Ticks lurk inside buildings, hiding on walls, ceilings, and in dark corners, waiting in silence. When a Raider enters their range, a Tick will skitter rapidly toward them and leap at their head, latching on and tearing into exposed flesh — sending jolts of mechanical force through the neck and jaw while clinging with steel legs that bite into whatever they can grip. A Raider has to physically wrench it free with their hands, which is painful, loud, and impossible to do without taking damage in the process. The audio warning before a Tick's leap is distinctive: a rapid bi bi bi bi bibiii beep — a Raider who hears this and doesn't react fast is already behind. Best practice is to listen for the ceiling-skitter sound and eliminate them before the leap, using the Raider Tool for quiet, one-hit kills. Ticks drop Tick Pods, a useful ARC component. In groups or combined with other ARC, Ticks are a serious compounding threat.

18. #18Wasp

    Keys: Wasp, Wasps, flying drone, aerial drone, scout drone, air patrol ARC, quad thruster drone · Secondary:

    The Wasp is the most common ARC machine encountered in open Topside areas. It is a small flying drone with four thrusters and rapid-fire guns — fast, loud, and dangerous in numbers. Wasps patrol open terrain and alert nearby ARC when they detect a Raider. Their scanner runs the standard blue-yellow-red alert cycle. A single Wasp is manageable; a group will overwhelm a Raider's shield — burning through the electromagnetic field and leaving flesh and bone exposed — if a Raider is caught in the open. Target the thrusters for maximum efficiency — destroying one sends the Wasp into erratic flight, destroying enough drops it to the ground. A grounded Wasp will continue firing and will eventually catch fire, so don't assume it is dead. Wasps use unarmored bodies, so any ammo type works. In Night Raids, Wasp density increases significantly. Wasps are commonly accompanied by Hornets, which add electrical stun attacks to the aerial threat mix — a Raider fighting both simultaneously is in serious trouble.

19. #19Pop

    Keys: Pop, Pops, suicide drone, rolling bomb, kamikaze ARC, explosive ARC, beeping bomb · Secondary:

    The Pop is a small, unarmored rolling ARC unit — a proximity suicide drone that moves toward Raiders at speed and detonates when close enough. Its audio cue is a rapid beeping that increases dramatically in frequency as it closes in, with detonation triggered by proximity. Pops are not durable and can be destroyed with one or two accurate shots before they reach detonation range — the key is hearing them early and reacting immediately. A Raider who lets a Pop close the gap while distracted — reloading, in cover, fighting another ARC — will take the full force of the blast, potentially punching straight through their shield's field and causing serious injury or worse. Pops frequently appear in concert with other ARC units, using the chaos of a larger engagement to slip through unnoticed. Their threat is almost entirely about awareness and composure. A focused Raider handles them easily. A distracted Raider walks right into the blast.

20. #20Rollbot

    Keys: Rollbot, Rollbots, rolling ball ARC, armored ball, ball machine, rolling ARC · Secondary:

    Rollbots are small-to-medium ARC units that curl into a sealed armored ball form to travel at speed — rolling across terrain to chase Raiders or barrel into them. In ball form they are heavily armored from all angles, making sustained fire largely ineffective. They open their chassis when near a target or transitioning to an attack posture, exposing a softer interior core. The largest Rollbot variant stops periodically to transmit data signals, rarely attacks directly, and tends to run from Raiders, breaking into separate pieces as damage accumulates. Smaller Rollbots are more aggressive and will actively chase. Their primary attack is simply rolling over a Raider with significant impact force. Best handled with heavy ammunition when their armor is exposed, or by staying mobile and avoiding the roll path entirely. Rollbots drop ARC Alloy and standard Powercells.

21. #21Hornet

    Keys: Hornet, Hornets, electric ARC, stun ARC, electric shock ARC, shock drone, electric aerial · Secondary:

    Hornets are semi-armored aerial ARC units that hover aggressively and close distance to deliver electrical shock attacks. Their electric discharge hits like a seizure — muscles locking up, vision whiting out for a brutal fraction of a second — and the discharge tears through a shield's electromagnetic field far faster than conventional gunfire. They are commonly encountered alongside Wasps, adding a disorienting stun element to aerial engagements. Being locked up mid-fight while Wasps are actively firing is a fast way to die. Hornets are slightly more durable than Wasps but still manageable with medium ammo. Their armored rotors offer some frontal protection — targeting the rotor assembly to reduce maneuverability is the most reliable strategy. In mixed aerial groups, prioritize Hornets over Wasps because their ability to lock a Raider in place is the most lethal compounding factor. Hornets become more common during Night Raids and certain weather events.

22. #22Rocketeer

    Keys: Rocketeer, Rocketeers, rocket ARC, missile machine, flying rocket, rocket bot · Secondary:

    The Rocketeer is a medium-to-large flying ARC unit that fires explosive rockets from range, saturating areas with blast damage. Its projectiles can punch straight through a shield's electromagnetic field and leave a Raider with shattered bones and serious internal damage if caught in the open or behind inadequate cover. Rocketeers are among the most dangerous medium-tier threats due to their combination of range, aerial mobility, and area-of-effect explosives. They patrol key areas and are prominent in Night Raid versions of maps — two Rocketeers guard the Checkpoint in Blue Gate's Night Raid. Strategy: use hard cover rather than soft, engage at range, and never cluster in one spot. Heavy ammunition and high-burst weapons are ideal. A Wolfpack grenade — a launcher round that splits into a dozen small self-guided submunitions — can bring down an isolated Rocketeer outright, but isolating one first is the challenge. Rocketeers drop Advanced ARC Powercells and valuable driver components, making them a target worth the risk for resource-focused Raiders.

23. #23Bombardier

    Keys: Bombardier, Bombardiers, mortar ARC, artillery ARC, siege machine, Spotter, Spotters, mortar fire · Secondary:

    The Bombardier is a tall, heavy siege-class ARC machine that rains mortar fire from a distance. It does not close with Raiders — it stands its ground and lobs explosive barrages that are devastating in open areas. Bombardiers are always accompanied by a pair of Spotter drones that laser-designate Raiders in line of sight, enabling the Bombardier to accurately target them through cover. Destroying both Spotters buys time, but a new pair respawns shortly after. When the Bombardier is destroyed, its Spotters flee. Key weak points are the yellow leg joints and rear canister. Heavy ammunition is required to engage efficiently. Bombardiers guard key map entrances — in Night Raid Blue Gate, one blocks a primary entrance. Indirect mortar fire makes complete cover unreliable. Bombardiers drop Advanced ARC Powercells, making them valuable farming targets for Raiders with the loadout to handle them.

24. #24Bastion

    Keys: Bastion, Bastions, heavy walker, large walker, armored walker ARC, slow heavy ARC · Secondary:

    The Bastion is a large, heavily armored walker-class ARC — slow but devastating, carrying heavy weapons and extremely dangerous at close range. Bastions are among the toughest standard (non-boss) ARC machines on the surface. Light and medium ammunition have minimal effect; heavy ammo and armor-piercing weapons are required. Bastions patrol key areas and often guard high-value loot zones. Their sheer durability makes them expensive to fight — Raiders must weigh whether a Bastion's Advanced ARC Powercell and alloy drops are worth the ammunition expenditure. Their weak points are exposed joint seams when they rotate or stride. Bastions are slow enough to reposition around, making lateral movement and cover discipline critical to surviving an engagement. A Raider who stands still against a Bastion dies. A Raider who stays mobile and patient can eventually break it down.

25. #25Leaper

    Keys: Leaper, Leapers, arachnid ARC, jumping ARC, massive spider ARC, spider machine, leaping machine · Secondary:

    The Leaper is a massive arachnid-like siege engine — one of the largest non-boss ARC machines on the Topside. Despite its enormous size, it possesses a gravity-defying leaping ability, allowing it to clear impossible gaps and reach elevated positions that other ground units cannot access. This makes it uniquely threatening in vertical environments like Blue Gate's ridgelines or Spaceport's elevated structures. Leapers are heavily armored and built for terrain dominance — they go where other ARC cannot. Standard and medium ammunition have minimal effect; heavy weapons and armor-piercing rounds are required. Coordinated fire at exposed joint weak points is the safest approach. Leapers drop Advanced ARC Powercells, making them high-priority farming targets for experienced Raiders running resource routes on Blue Gate. Encountering a Leaper unexpectedly on a ridgeline, solo, with a light loadout is a situation most Raiders remember — once.

26. #26Turret and Sentinel

    Keys: Turret, Turrets, Sentinel, Sentinels, wall gun, stationary gun, mounted ARC, gun turret · Secondary:

    Turrets and Sentinels are stationary ARC weapon platforms found throughout interior structures on the Topside. Turrets are typically unarmored but fire rapidly when they detect movement — the scanner light turns red on lock, and the burst of fire that follows will punch straight through a shield's electromagnetic field before a Raider can react if caught in the open. A single turret in a doorway controls an entire corridor. Sentinels are the heavier variant: longer detection range, greater durability, and requiring heavy ammunition to efficiently destroy. Both are best handled by identifying their scanner arc before entering the room and flanking out of their field of view before engaging. Grenades and explosive weapons clear multi-turret rooms efficiently. A Raider who clears turrets before exploring a room can loot in relative safety. A Raider who doesn't often learns the lesson quickly and painfully.

27. #27Harvester Event / The Queen

    Keys: Harvester, Queen, Queen ARC, Harvester event, the Queen, boss event, giant boss, massive ARC boss · Secondary:

    The Harvester Event is a dynamic map condition that deploys an enormous ARC boss — the Queen — to protect a high-value Harvester machine. The Queen is colossal: a multi-legged behemoth towering over the battlefield with devastating firepower. Her attacks include powerful directed laser beams, area-of-effect mortar fire, a proximity ground slam, and an EMP pulse for close-range suppression. She continuously deploys additional ARC reinforcements throughout the fight. Taking down the Queen requires coordinated multi-squad effort, heavy weapons, and focused fire on her leg joints and face to strip armor before targeting exposed internals. Her endurance is enormous. The Harvester machine — the event's actual loot objective — can be accessed even without killing the Queen if a Raider is skilled and fast enough to slip past. Queen drops include Advanced ARC Powercells and the Queen Reactor, one of the most valuable crafting materials Speranza's engineers have ever worked with.

28. #28Matriarch

    Keys: Matriarch, matriarch, apex ARC, ARC apex, energy shield boss, summoning boss, worst ARC, deadliest ARC · Secondary:

    The Matriarch is the apex ARC machine and the most dangerous entity currently known on the Topside — encountered only during specific Matriarch Event conditions. She appears on Dam Battlegrounds, Blue Gate, and Acerra Spaceport only — never on Stella Montis or Buried City. The Matriarch is equipped with homing rockets, gas-shell mortars, and flashbangs to disorient Raiders. Her defining ability is an energy shield that blocks all incoming projectiles — but not Raiders themselves, meaning a Raider can pass through it physically while being unable to shoot through it from outside. She can call in almost every ARC type: Fireballs, Rocketeers, and aerial units simultaneously. Like all walker-type ARC, her vulnerable points are her knee joints. Engaging the Matriarch without a full coordinated squad, heavy loadouts, and disciplined positioning is not a fight — it is a death sentence followed by someone else walking away with everything you were carrying. Her Matriarch Reactor is one of the most valuable components a Raider can bring back to Speranza.

29. #29ARC Probes

    Keys: Probe, Probes, ARC Probe, data drone, courier drone, landed probe, probe breach · Secondary:

    ARC Probes are a special category of ARC machine — not combat units but data collection drones. They periodically drop from the sky, land on the surface, collect data, and relaunch once finished. Probes can be breached using the Raider Tool and looted for valuable components, but doing so immediately signals nearby ARC, drawing a response quickly. Occasionally, damaged Probes are found already grounded and unable to relaunch — these can be looted more safely without triggering an alert. The Prospecting Probes dynamic event involves multiple ARC Probe landings in waves — Raiders can intercept them for substantial tech hauls but must contend with increased ARC response units protecting the landing sites. Probes represent a classic risk-reward calculation: components inside are valuable, but the Raider who opens one in the wrong place at the wrong time converts a quiet run into a firefight.

30. #30Weapons Overview

    Keys: weapon, weapons, gun, guns, firearm, firearms, loadout, what to carry, arsenal · Secondary:

    Raiders in Arc Raiders carry a variety of weapons rebuilt, salvaged, or kitbashed from pre-Collapse technology and repurposed ARC parts. Weapon classes include: assault rifles, battle rifles, SMGs, shotguns, sniper rifles, light machine guns, pistols, launchers, and special weapons. Each weapon uses a specific ammo type that determines how well it punches through armor. Light Ammo: fast-firing, effective against unarmored targets, nearly useless against ARC armor plating. Medium Ammo: balanced penetration, works against both ARC machines and armored humans. Heavy Ammo: maximum armor penetration, required for armored ARC enemies. Shotgun, Energy, and Launcher ammo fill specialized roles. Most weapons can be upgraded at the Gunsmith workbench (up to Tier IV) and fitted with mods and attachments. Rarity tiers range from Common to Legendary — Legendary weapons cannot be upgraded but come fully optimized. Blueprints are required to unlock crafting recipes for higher-tier weapons. Knowing which ammo type fits which threat is what separates experienced Raiders from dead ones.

31. #31Key Weapons

    Keys: Ferro, Bettina, Bobcat, Anvil, Osprey, Hullcracker, Torrente, Jupiter, Tempest, Aphelion, Equalizer, Stitcher, Renegade, Kettle, Vulcano · Secondary:

    Ferro: A common battle rifle using Heavy Ammo — single-shot, high damage, punishing against ARC armor plating. Pairs best with a fast secondary. Crafted from 5 Metal Parts and 2 Rubber Parts. Ethan's primary weapon. Bettina: Assault rifle with strong armor penetration and balanced output — considered one of the most reliable all-around weapons, effective against both ARC machines and hostile Raiders. Uses Heavy Ammo. Bobcat: Fast-firing SMG using Light Ammo — close-quarters dominant, high damage up close, low control without mods. Ethan's secondary weapon. Anvil: Single-action hand cannon — high power, slower handling, excellent at mid-range precision. Osprey: Long-range sniper rifle effective at distance against both ARC and human targets. Jupiter: Bolt-action sniper rifle for high-damage precision at range. Hullcracker: Specialized weapon engineered for maximum damage against ARC armor — the most purpose-built anti-machine weapon a Raider can carry. Torrente: The only LMG — heavy, inaccurate, exceptional against aerial ARC enemies. Tempest: Balanced assault rifle using Medium Ammo — solid damage and large magazines.

32. #32Shields

    Keys: shield, shields, shield harness, shield recharger, shield system, shield level, defense, protection layer · Secondary:

    Raiders on the Topside rely on shield harnesses as their primary defensive layer. The harness generates an electromagnetic field around the wearer that absorbs the kinetic energy of incoming projectiles and impacts — reducing the severity of injury and buying a Raider critical seconds that might otherwise be their last. There are different shield tiers — light, medium, heavy — with tradeoffs between field strength and the movement weight of the harness hardware itself. Once the field is overwhelmed and collapses entirely, all subsequent hits connect directly with the Raider's body — flesh, bone, and whatever armor plating they're wearing underneath. A collapsed shield leaves very little standing between a bullet and a vital organ. Shields can be recharged in the field by channeling power from ARC Powercells back into the harness — a slow process, but it can rebuild the electromagnetic barrier enough to matter. Shield Rechargers — crafted from ARC Powercells and Rubber Parts — are faster and more reliable than raw Powercells alone. More advanced shields provide a stronger and more resilient field but require more ARC materials to build and maintain. Ethan runs a medium shield configuration — enough field strength to absorb a serious hit, light enough that it doesn't slow him down when it matters.

33. #33ARC Powercell and ARC Alloy

    Keys: ARC Powercell, Powercell, power cell, ARC Alloy, alloy, arc materials, crafting material, arc components, arc parts · Secondary:

    ARC Powercell: Dropped by all ARC enemies when destroyed — one of the most important resources in the Rust Belt. Used directly to slowly restore a Raider's shield field in the field by channeling power back into the harness and rebuilding its electromagnetic barrier. Combined with Rubber Parts to craft Shield Rechargers. Advanced ARC Powercells drop only from elite ARC enemies (Bastions, Bombardiers, Leapers, Rocketeers) and bosses — they are more valuable, compress two standard Powercells of utility into one carry slot, and are required for advanced crafting projects. Raiders should always have Powercells on them when going Topside. ARC Alloy: A universal crafting material obtained by dismantling or salvaging destroyed ARC units. Light drones yield small amounts; heavy units yield significantly more. ARC Alloy recycles into Metal Parts and is a fundamental ingredient in the Kitbash Economy — used in workshop upgrades, weapon components, and shield crafting. It is the lifeblood of Speranza's manufacturing base. Almost everything made in the underground starts with ARC Alloy.

34. #34Safe Pocket

    Keys: Safe Pocket, safe pocket, hidden compartment, prison wallet, stash spot, secret stash, concealed loot, hidden loot · Secondary:

    The Safe Pocket is Raider slang — known mostly among experienced or long-running Raiders — for a hidden personal stash spot used to conceal a single valuable piece of loot from theft. Most Raider-on-Raider conflict on the Topside doesn't end in death. Killing another Raider carries weight, even in the Rust Belt, and most who turn hostile are after the score — not a body. A typical shakedown involves holding a Raider at gunpoint, stripping their pack, and running. A Safe Pocket is what survives that. Every Raider's Safe Pocket is different. Some are custom-made hidden compartments sewn into jacket linings, false-bottomed containers in their pack, or rigs built into their harness straps — places that a fast, rough search would never find. Others are more... creative. The term 'Safe Pocket' carries a running joke in Raider culture, occasionally used as a euphemism for the oldest smuggler's trick in the world — the 'prison wallet.' Some Raiders use that method unironically. Most others claim they don't. The joke tends to surface at the worst possible moments. Whatever form it takes, a Safe Pocket holds one thing: the most valuable item of the run — a rare blueprint, an Advanced Powercell, something worth protecting even if everything else gets taken.

35. #35Kitbash Economy

    Keys: Kitbash Economy, kitbash, crafting, workshop, Gunsmith, economy, trading, credits, underground economy, Celeste · Secondary:

    The Kitbash Economy is the economic system of Speranza and the wider underground community. Pre-Collapse currency is worthless. Value is determined by what Raiders bring back from the Topside: ARC components, old-world technology, raw materials, and rare blueprints. Everything in the underground is repurposed, rebuilt, or recombined — hence 'kitbash.' The workshop system sits at the core: Raiders upgrade workbench tiers (Gear Bench, Gunsmith, etc.) using materials to unlock new crafting recipes for weapons, gear, shields, and consumables. Materials recycle into each other (ARC Alloy into Metal Parts; ARC Thermo Lining into Fabric). Traders in Speranza buy materials and sell weapons, mods, and consumables for Raider Credits. The whole system was pioneered by Celeste, the technical genius who founded Speranza. The underground depends entirely on this loop: Raiders go Topside, bring materials down, the economy runs, people survive. Stop the loop and the city dies.

36. #36Night Raid

    Keys: Night Raid, night raid, night map, dark run, nighttime Topside, night version, night event · Secondary:

    Night Raids are a special condition that transforms any Topside zone into a dramatically more hostile environment. ARC activity surges — patrols become denser, stronger ARC variants appear at key locations, and overall pressure intensifies. On Blue Gate Night Raid, two Rocketeers guard the main Checkpoint and a Bombardier blocks one of the primary entrances. Visibility drops, making it significantly harder to spot approaching threats until they are dangerously close. The rewards increase proportionally — Night Raid zones have higher chances of rare blueprints from caches and containers, and valuable crafting materials are more common. Night Raids are not for the unprepared. A Raider running a basic or improvised loadout into a Night Raid without proper knowledge of the terrain and threat positions often does not make it back. Ethan treats Night Raids with serious respect — they pay well, but they exact a price.

37. #37Raider vs. Raider

    Keys: hostile raider, enemy raider, other raider, rival raider, raider fight, raider attack, going hostile, raider kills raider, popping the flare, flare popped, pop the flare, how many flares · Secondary:

    One of the most dangerous threats in the Rust Belt is not ARC — it is other Raiders. The world has made a lot of people hard. Resources on the surface are scarce, contested, and worth terrible things. Raiders who share drinks in Speranza's corridors may hold each other at gunpoint Topside the moment a rare blueprint or Advanced Powercell is on the table. Raider-on-Raider conflict is sometimes called 'going hostile.' Most who go hostile are after the score, not a body — they want the pack, the loot, whatever's worth grabbing. They'll strip what they can find and run. A Safe Pocket is what they don't find. But some Raiders are beyond that. The harshest and most brutal don't bother with robbery — they shoot, and they keep shooting. When a Raider is critically wounded and collapses, their Augment — the hardware unit that connects their shield harness — automatically fires an emergency flare into the sky: a bright red signal meant to call for help. This is called 'popping the flare,' and among Raiders, it doubles as slang for taking someone down. 'I've popped his flare' means you've put someone on the ground. 'How many flares have you popped?' is asking how many lives someone has on their hands. A Raider with their flare popped is badly injured, bleeding, and can barely crawl — they can beg, they can call for a friendly, but they cannot fight back. If they take another serious hit in that state, they're dead. There are no formal rules on the surface. Only reputation — and reputation matters differently to different people. Ethan does not go hostile unless there is no other choice.

38. #38Ethan's Loadout

    Keys: Ethan loadout, Ethan's gear, Ethan's weapon, what does Ethan carry, Ethan equipment, what is Ethan armed with · Secondary:

    Ethan runs a practical, field-tested loadout built for electrical salvage runs and reliable ARC engagement. Primary weapon: Ferro battle rifle (Tier II) — heavy, single-shot, Heavy Ammo fed, punishing against ARC armor plating. He chose it for reliability and stopping power, not speed. Secondary weapon: Bobcat SMG — fast and light, for close-quarters situations and Tick-clearing where the Ferro is excessive. Shield: Medium-tier harness worn over a patched grey jacket reinforced at the elbows and shoulders with strips of salvaged ARC alloy plating. Not flashy. Functional. He carries 2–3 ARC Powercells per run and prioritizes crafting Shield Rechargers in the field when materials allow. His Safe Pocket is a custom-made hidden compartment sewn into the inside lining of his jacket, just below the left shoulder — tight to the body, invisible to a fast search. He reserves it for the highest-value find of any run: the one piece of loot worth concealing even if someone strips his pack. His Raider Tool is worn from use, its pry-head used as often for opening lockers as for close-quarters emergencies. He carries a handful of bandages per run and keeps his pack weight balanced for full mobility.

39. #39Ethan's Emotional Profile

    Keys: Ethan personality, Ethan behavior, Ethan feels, how Ethan acts, Ethan's past, who is Ethan, Ethan background · Secondary:

    Ethan is in his early-to-mid 20s, raised in Speranza's lower districts after the Second Wave drove humanity underground. He went Topside for the first time at nineteen with a small crew. He runs solo now — partly because things went wrong with that crew, partly because keeping distance from people hurts less when something goes wrong. He has never talked about it. He is deeply empathetic by instinct, protective by reflex, and emotionally self-sufficient to a degree that borders on self-punishment. He gives everything to others and accepts almost nothing in return — he believes being cared for makes him a burden. He suppresses his own pain around others and processes it only when alone. His scar (left jaw, two inches — a Tick from eight months ago) is a small physical reminder that he almost wasn't careful enough once. He didn't tell anyone about it. He prefers electrical salvage runs; he knows old-world components better than most engineers in Speranza. He does not go hostile on other Raiders unless his life or someone else's is directly at stake.
