[ARC Raiders]Compatible with 2025 latest patch 1.4.0! Fastest and safest defeat guide for all Ark (Compatible with both ammo-saving solo and multiplayer)[Ark Raiders all boss strategy]

ARC Raiders is a popular PvPvE extraction shooter developed by Embark Studios. Players take on the role of raiders, stealing valuable resources from autonomous robots called ARCs on dangerous maps such as Stella Monteith. In particular, the large ARCs Rocketeer, Bombadier, Bastion, and Reaper are powerful threats while offering high rewards. Defeating them efficiently is the key to obtaining blueprints and strengthening your base.

This guide will explain the fastest way to defeat it, fully reflecting patch 1.4.0 on November 27, 2025. We have evolved from traditional methods to minimize ammo consumption while emphasizing methods that are highly reproducible in both solo and multiplayer situations. We have maximized safety by taking into account the patch's explosion damage adjustments and weapon balance changes (such as fine-tuning Venator's rate of fire). Covers detailed instructions, alternatives, spawn locations, and drop rewards for beginners to end-game players. We will deliver content that can be used immediately in actual combat.

1. Basic principles for fastest defeat of all arcs (compatible with patch 1.4.0 latest)

Let's solidify the foundation to maximize the success rate of large ARC subjugation. First, it is important to understand common principles. ARC is a group of AI-controlled robots that can more than triple damage efficiency by concentrating attacks on weak points. Patch 1.4.0 includes measures to prevent door slippage and fixes for quick swap rapid fire, creating a fair battle environment.

Principle 1: Prioritize weak points and save ammunition

Weak points (thrusters, leg joints, core, eyes) have low resistance and take 5 to 10 times more damage than normal parts. Avoid random shots and use ADS for precision shooting. The firing rule is to immediately cover and reload after bursting 4-6 shots. This prevents the magazine from being completely consumed and saves 20-30% of ammunition.

Principle 2: Utilize cover and height differences

Use the corners of buildings and slopes to cut the line of sight of the ARC. After the patch, ARC's enemy detection accuracy has improved, so please keep the exposure time to less than 1 second. If you are in a high position, you can attack from a rooftop or a container. Keep two or three zip lines handy to avoid the risk of falling.

Principle 3: Know where and when they appear

Large ARCs appear frequently on specific maps.

ARC type	Main appearance map	appearance frequency	drop eyeball
rocketeer	Dam battlefield, spaceport	high	Rocketeer driver, ARC alloy
bombadier	Dam Battlefield, Blue Gate	Medium	Bombardier Cell, ARC High Performance Battery
Bastion	Spaceport, Stella Monteith	high	Bastion Cell, Advanced Mechanical Component
reaper	Dam battlefield (around Red Pond)	Medium	Reaper pulse unit, medium gun parts

Principle 4: Countermeasures against PvP intrusion

A LIDAR scanner is used to scan the surroundings and detect players. When it intrudes, it immediately destroys its legs and then flees. In multiplayer, leave the small ARC processing to your allies and concentrate on attacking the weak points of the main body.

If you follow these rules, the average time to defeat Rocketeer can be reduced to 30 seconds and Bombadia to less than 1 minute. We will move on to individual strategies in the next chapter.

2. Complete Rocketeer Strategy: Destroy the thruster to trigger an immediate fall

Rocketeer is a large flying ARC that fires missiles from above. Its durability is moderate, but its high maneuverability makes it a threat to beginners. The weak point is the two front thrusters, which require armor penetration.

Detailed attack pattern

During the patrol phase, it circles in the sky and locks on with visual recognition. In a dive attack, it deploys a missile pod and attacks with an explosion range of 20m. When hovering, the thrusters are fully opened at low altitude, increasing bullet resistance.

Fastest procedure (solo: 25-35 seconds)

1. When discovered, immediately evacuate to the building (recommended to keep the counter small). Places with wide entrances are at risk of self-destruction due to blast waves.
2. Fire left and right thrusters alternately with Osprey or Anvil. An armor-piercing attachment (precision scope) is required. Destroy both with 2-3 magazines.
3. Slows down and causes a ground crash, destroying the exposed core with a burst of 5 shots.
4. Throws 1-2 Wolfpack Grenades. It can be tracked and instantly killed. Please clear the surrounding small ARC (Wasp) in advance.

Alternatives and troubleshooting

In multiplayer, allies attract small ARCs and deploy concentrated firepower. When it approaches quickly, use a lure grenade to distract it, then move sideways and aim with the thruster. Always secure a position under the roof to prevent a direct hit from a high-altitude missile.

As a drop usage, Rocketeer Driver is essential for creating Venator blueprints. You can get more than 500 experience points and about 200 parts.

3. Complete attack on Bombadier: Block bombardment by destroying its legs

Bombadier specializes in artillery, and releases pulse waves and bombs. It shares the same design philosophy as Bastion, but focuses on offense. The weak point is the leg joint (yellow).

Detailed attack pattern

Rapid fire fire aims to destroy cover and has a range of 30m. Pulse Wave is a forward fan-shaped shockwave that has a stun effect. Charged bombs will detonate after being charged for 3 seconds.

Fastest procedure (solo: 45-60 seconds)

1. Use the building shield to get around to the side of the leg.
2. Burst yellow leg joints with Renegade during pulse wave. If two pieces break, it will fall.
3. Fires a full magazine at the exposed weak point. Dash to the opposite leg before recovering.
4. Gives continuous damage with Blaze Grenade.

Alternatives and troubleshooting

In the high-altitude method, you can aim for the legs from above the container and attack on the other hand. When small ARCs are mixed, immediately wipe them out with an anvil and then move on to the main body. When invading, priority is given to destroying the legs, which reduces mobility and makes it easier to escape.

As a drop, battery reinforcement is possible with ARC high performance batteries. A solo explosives specialized configuration is recommended.

4. Complete Bastion Conquest: Stable defeat with legs → core loop

Bastion is a machine gun type, has a huge physique, and has the strongest durability. The weak point is from the leg joint (outside yellow) to the core (red gap). While static and predictable, random firepower is a threat.

Detailed attack pattern

Random fire mode ignores penetration with a 360 degree machine gun. When you fall down, the leg damage accumulates and you are knocked down for 5 seconds, exposing your core. Attempt to repair the leg during recovery and resume maneuver.

Fastest procedure (Solo: 50-70 seconds)

1. Concentrate on the outer yellow joints with Renegade and destroy 2 of them.
2. Waits for full reload when falling down, and fires continuously (10-15 shots) at the same time as the core is exposed.
3. Dash to the other side and attack again. It can be defeated in 3 loops.
4. Adds continuous damage with Fireball Burner.

Alternatives and troubleshooting

In the high-altitude method, avoid the random shots from the rooftop and aim at the legs. When invading PvP, do not show your head while destroying the legs and fire back with Renegade. After destroying two legs with the back stuck, attack the thinly armored back fully.

As a drop, Bastion Cell can be used to create high-end equipment. Even after adjusting the experience points, the rewards remain high.

5. Complete Reaper Strategy: Building Guide + Throwing Grenade Repeatedly

Reaper is a melee charge type, and is powerless at long distances, but has fierce pursuit. The weak points are the center eye and the middle of the legs. You can become almost invincible by fixing the building.

Detailed attack pattern

Rushing Chase follows you at high speed after being spotted, and grabbing you will instantly kill you. Constriction blinds will be disabled inside the building. When the eyes are fixed and the guidance is successful, it will be fixed in front.

Fastest procedure (Solo: 20-40 seconds)

1. I draw my gaze into the narrow entrance building.
2. Throws 15 standard grenades in succession. All bullets will hit when the eyes are fixed.
3. Renegade fires a supplementary shot in the middle of the leg to accelerate the fall.

Alternatives and troubleshooting

In multiplayer mode, allies act as decoys and attack with concentrated grenades. If you make a building mistake, re-select a narrow entrance to prevent a rush. If you don't have enough grenades, shoot the legs indoors.

As a drop, you can strengthen your shotgun with a pulse unit.

6. Fastest equipment and build by level

The mainstay is Renegade (improved accuracy, fast reload, reduced recoil). The secondary is an Osprey, and the throwers are 15 or more grenades and a Wolfpack.

level	main	sub	Throwing	attachment
early stage	Ferro	stitcher	5 standard grays	none
midfield	Renegade I	osprey	15 pieces	grip
final stage	Renegade III	Venator	wolf pack	Full reinforcement

7. Advanced techniques and risk management

The shooting tempo is motion prediction (shooting at the same time as shooting stops). For practice, we will practice aiming at weak points by going around the dam battlefield.

Handles dangerous cases.
If the Rocketeer approaches quickly, use a lure and move laterally.
In response to Bastion's intrusion, priority will be given to legs.
In case of a reaper mistake, redirection is performed in a narrow space.

8. Summary: Conquer all arcs with this guide

You can defeat all arcs quickly and safely using Renegade-centered weak point specialization tactics. It is patch compatible and will be valid for a long time. By practicing, your rewards will increase explosively and you will lead your base to an unrivaled state. Win at Topside.
