Tiny spider-like ARC machines that cling to walls and ceilings, waiting to ambush unsuspecting players. When a target passes below, they leap onto the head and detonate. Individually fragile but terrifying in dark interiors where they hide in clusters.
Small rolling explosive ARC balls that rush toward detected players and detonate on contact. Their spherical design allows them to roll at surprising speed across flat terrain. The explosion radius is larger than their tiny size would suggest.
The most common ARC enemy in the game. Wasps are basic flying drones armed with a rapid-fire gun that deals steady chip damage. They appear in nearly every encounter and are often the first ARC a new player faces.
Rolling flamethrower bots that patrol in groups and spray fire at close range. Fireballs are squat, ball-shaped machines with an extending flame nozzle. Their white-hot core is normally shielded but becomes exposed when they attack.
Scout drones (also known as Spotters) that fly at high altitude scanning for players. Snitches are not directly dangerous but their true threat is revealing your position to every other ARC in the area. Letting one live can turn a quiet looting run into a swarm fight.
A flying ARC drone that spews fire from above, adding aerial pressure and forcing vertical awareness. The Firefly is very aggressive and hard to shake once it locks on. It typically patrols alongside Wasps or Hornets, though it sometimes appears alone. Added in the Shrouded Sky update, it thrives during Hurricane conditions where low visibility makes its flame attacks even more dangerous.
A heavily armored ground-based ARC that rolls at high speed like a Fireball, but far more dangerous. When a Comet spots a Raider, it locks on and charges at them, splitting open its armor to reveal an explosive core before detonating with a devastating seismic boom. It breaks defensive setups and punishes static play. Added in the Shrouded Sky update.
Flying ARC drones with electric shock attacks that stun players on hit. Hornets are semi-plated aerial units that hover aggressively and close distance to deliver debilitating electric discharges. Getting stunned by a Hornet in a firefight is often a death sentence.
Stationary gun emplacements found inside buildings and fortified positions. Turrets are unarmored and relatively fragile, but their rapid-fire output and placement at chokepoints make them surprisingly lethal to players who rush in without checking corners.
Heavy stationary sniper turrets usually found on rooftops and elevated positions. Sentinels deliver devastating long-range shots that can chunk most of a player's health in a single hit. Their distinctive yellow canister on the arm is their critical weak point.
Large spherical rolling ARC machines that patrol zones with a powerful laser weapon. Surveyors are heavily built balls of metal that roll along routes, stopping to fire a precision laser beam at detected players. Their armor is formidable except when they open up to fire.
Heavy flying ARC enemies that fire devastating projectile attacks. Shredders are bulky aerial platforms exclusive to Stella Montis. Their aggressive attack patterns and airborne mobility make them one of the most dangerous medium-tier threats in the game.
Fully plated ball-shaped ARC machines that roll at high speed to crush players. Rollbots are heavily armored from all angles while in ball form, making them resistant to sustained fire. Their primary attack is simply rolling over you with tremendous force.
Siege-class ARC machines that fire mortar rounds in devastating barrages. Bombardiers are tall, heavy units that rain explosives from a distance, making them extremely dangerous in open areas. Their yellow leg joints and rear canister are the key weak points that experienced players target.
Siege-class 4-legged ARC tank with a massive turret mounted on top. Bastions are walking fortresses with heavy frontal armor and a powerful main cannon. They are among the most imposing non-boss enemies in the game and require focused team fire to bring down efficiently.
Assault-class ARC machine (also known as Bison) that leaps extraordinary distances and releases a kinetic energy shockwave on landing. Leapers are large, powerful units that close gaps instantly with their signature leaping attack, making distance and cover much less effective against them.
Aerial heavy weapons platform armed with a devastating rocket launcher system. Rocketeers are large flying ARC machines that hover above the battlefield and rain rockets down on player positions. Their size and altitude make them hard to miss but their HP pool demands sustained fire.
A terrifying aerial ARC machine introduced in the Flashpoint update. The Vaporizer combines the speed of a Rocketeer with a Matriarch-grade energy shield and precision laser attacks that will obliterate your shield and set you on fire in under two seconds. It patrols the airspace around ARC Operations and Close Scrutiny events. Killing it drops the Vaporizer Regulator required to craft the Dolabra energy shotgun.
An unarmed ARC machine with a powerful thruster system that regularly descends from orbit to collect air and soil samples. The Assessor is a large stationary ARC unit that lands during the Close Scrutiny ARC Operation. It does not roam — it holds a fixed position, surrounded by heavy ARC patrols including Vaporizers. While unarmed, breaching its 3 sections triggers deadly ARC reinforcement waves. Contains high-tier loot including ARC Powercells, ARC Alloy, ARC Circuitry, and the coveted Assessor Matrix.
Apex-class ARC machine also known as the Harvester. The Queen is a gigantic robot that appears during the Harvester event. She towers over the battlefield and requires coordinated squad effort to defeat. Her massive health pool and devastating attacks make her the most iconic boss encounter in ARC Raiders.
Apex-class ARC machine and the deadliest boss in the game. The Matriarch projects an energy shield that blocks all incoming projectiles and has the ability to summon waves of ARC reinforcements. She only spawns during Matriarch events on Dam Battlegrounds, Blue Gate, and Spaceport. She NEVER appears on Stella Montis or Buried City.
The ARC invasion has deployed a wide array of mechanized threats across every zone in ARC Raiders. From tiny Ticks that swarm in packs to the devastating Matriarch boss encounter in Stella Montis, each enemy type demands different tactics, loadouts, and awareness.
Understanding weak points is the difference between burning through your ammo and dropping an enemy in seconds. Every ARC unit has exploitable vulnerabilities — optic sensors, exposed power cores, rear exhaust ports — and hitting them deals multiplied damage. Our guides break down every weak point, every drop, and every combat tip so you can fight smarter.
Use the RATWATCH enemy database alongside our weapon guides and map intel to build the perfect loadout for any zone. Whether you are farming materials from Turrets in the Spaceport or preparing for a Queen encounter at the Dam Battlegrounds, this intel will keep you in the fight.
