How To Kill A Bastion Arc Raiders – Full Practical Guide

Bastion is one of the scariest early minibosses in Arc Raiders, so it is no surprise many players search for how to kill a Bastion Arc Raiders without getting shredded by its minigun. Bastion is a slow but heavily armored walking pillbox that patrols valuable resource areas and can lock down open ground with devastating fire. If you do not understand its weak points and attack cycle, it feels almost unkillable. Once you do, it becomes a predictable, farmable target that drops Bastion Cells and high value loot.

What A Bastion Is And Why It Feels So Dangerous

Bastion is a large ground ARC equipped with heavy frontal armor and a mounted minigun. Its main role is area denial: it locks lanes with sustained fire, punishes anyone crossing open spaces and often appears near good resource deposits, sometimes with supporting air units.

Two things make Bastion dangerous for new players:

• Its front armor shrugs off most small arms, so you waste ammo if you shoot the chest.
• Its minigun has a loud screech followed by a burst that can down you quickly if you are caught in the open.

That combination punishes impatience and bad positioning, but also hides the fact that Bastion actually has clear, exploitable weak points.

Bastion Weak Points – Where You Must Aim

To really learn how to kill a Bastion Arc Raiders, you need to ignore its front plating and target its weak spots. Both official style guides and the Arc Raiders wiki highlight two main weak areas:

• Yellow knee joints on the legs
  Bastion’s legs have unarmored yellow kneecaps. Hitting these knee joints deals direct damage and can stagger or stun the Bastion for a short time.
• Rear canister and inner cylinder
  On its back, Bastion carries a yellow canister. Destroying this canister stuns it and peels back the rear plate, exposing a barrel like core that takes massive damage. Shots into this exposed cylinder chunk its health far faster than any other target on the body.

If you keep shooting the front, you are effectively shooting a shield. The fight only opens up once you start systematically breaking legs and attacking the rear core.

Reading The Bastion Attack Cycle

Bastion is dangerous, but its attack pattern is incredibly readable once you pay attention. Understanding this rhythm is a big part of mastering how to kill a Bastion in Arc Raiders.

Basic attack cycle:

• Bastion lets out a sharp screech as an audio cue before firing its minigun.
• After the screech, it sprays a burst of bullets at the last spot it saw you, for roughly a few seconds.​
• Its chassis is slow to pivot, so it takes time to track new positions after committing to a firing lane.

This creates a simple loop you can use:

1. You peek from cover to make Bastion see you.
2. When it screeches, you immediately get back behind cover or break line of sight.
3. It empties its burst into your previous position while you are safe.
4. As the burst ends, you move to the side or rear and shoot weak points.

If you move with the screech timer instead of panicking, you effectively control when Bastion fires and when you attack.

Best Weapons, Grenades And Damage For Bastion

You do not strictly need endgame gear to kill Bastion, but certain weapon types and grenades make the fight much easier.

Recommended damage options:

• Heavy weapons such as rocket launchers and grenade launchers to crack leg joints and rear plating quickly.
• High impact rifles that can reliably hit yellow joints and the rear core at medium range.
• Blaze Grenades and Snap Blast Grenades, which deal strong damage to armor and weak points, especially when attached to the back canister.​

Some players even recommend loading up on multiple trigger grenades or a stack of impact grenades to burst a Bastion down in a single aggressive assault, reducing the window where other raiders can third party you.

Step By Step – How To Kill A Bastion Arc Raiders

You can break the whole encounter into clear steps that work both solo and in squads.

1. Choose good terrain
   Pick an area with strong, solid cover and multiple angles, such as rocks, buildings or dunes with ridges. Avoid flat open ground where Bastion’s minigun turns you into a target dummy.​
2. Trigger the screech and respect it
   Peek out just long enough for Bastion to see you. When you hear the screech, immediately move back behind cover. Let it waste its burst on where you were instead of where you are.
3. Work the knees
   As the burst ends, slide or strafe out at a slight angle and shoot the yellow knee joints. Short exposures here will chip its health and occasionally stagger it without exposing you for too long.
4. Rotate to the rear
   Once you have some distance or a flank, rotate around Bastion’s side to get an angle on the rear canister. Use the time between bursts to move; go back to cover whenever you hear the screech again.
5. Break the canister and hit the core
   Hit the yellow canister with your strongest damage, ideally heavy weapons or grenades. Destroying it will stun Bastion and peel open the rear plate, revealing the inner cylinder.​
   During this stun window, focus everything on the exposed cylinder and leg joints to deal massive damage.
6. Repeat until it collapses
   If Bastion survives the first cycle, repeat the pattern: bait screech, hide, flank, break joints and the rear, then punish the stun. With proper weak point focus, you only need a few cycles to kill it.

Solo Tips – How To Kill A Bastion Alone

Soloing a Bastion is absolutely possible if you focus on terrain and patience.

Helpful solo ideas:

• Bait and shift: each time you force the screech, use that burst window to change cover positions and gradually work toward its rear.
• Mine the path: place mines or explosive traps along the route you expect it to patrol, then coax it forward from behind cover so it walks into your damage.​
• Commit damage only on weak points: in solo play, long trades to the front are a death sentence. Only expose yourself to hit kneecaps or the rear cylinder.
• Use “burst kill” tactics: some players recommend stacking a large number of trigger or impact grenades, rushing in briefly to attach them, then detonating all at once to delete Bastion before you are third partied.

If supporting air units appear, always step back to cover and pick them off first. Keeping the sky clean is more important than maintaining constant DPS on Bastion.​

Common Mistakes That Get Players Killed

If Bastion keeps wrecking you, you are probably making one or more of these mistakes:

• Shooting the front armor
  You burn ammo and time shooting the chest. Its front plates are designed to soak damage and waste your resources.​
• Ignoring the audio cue
  Pushing forward while it screeches almost guarantees you will eat the full burst in the open.
• Fighting in open lanes
  Straight, unobstructed sightlines are perfect for its minigun. Without cover or elevation changes, you cannot safely dance around its fire cycle.​

Correcting these habits alone makes the fight dramatically more manageable.

What You Get For Killing Bastion

Killing Bastion is not just for pride. Bastions drop valuable loot, including Bastion Cells, which are needed for certain upgrades and crafting, as well as ARC parts and general high tier salvage. Guides note that Bastion Cells can appear on several different pieces of the destroyed machine, so you should always loot every chunk of wreckage after the fight to avoid leaving rewards behind.

Some locations, like Stella Montis, seem to spawn Bastions more reliably, turning them into repeatable minibosses for players who understand how to kill a Bastion Arc Raiders efficiently.
