ARC Raiders - Bastion Guide: Spawn Locations, Loot and How to Kill

Bastions are among the most dangerous ARC machines you’ll face in ARC Raiders. Imagine a slow-moving walking fortress, covered in thick armor, armed with a minigun capable of turning any Raider into Swiss cheese in seconds. They may look intimidating at first glance, but trust me: once you understand their behavior, attack patterns, and weak points, Bastions become predictable and farmable.

Defeating a Bastion rewards Bastion Cells, which are essential for upgrading your Gear Bench to Level 3. This makes them a must-farm target for any Raider looking to progress efficiently through mid and late game raids. Having spent hundreds of hours topside, I’ll walk you through everything from spawn locations and weapon loadouts to solo strategies, squad tactics, and even advanced “cheese” methods that veteran players swear by.

Bastion Behavior and Attacks

Understanding Bastion mechanics is critical. Their minigun fire is deadly, but predictable once you know the cues:

• Minigun Burst: Emits a loud screech before firing a 3 second gatling attack at the last known Raider position. Timing is everything learn to move and peek between bursts.

• Weak Points: Yellow leg joints and the rear yellow canister. Hitting these stuns the Bastion, exposing its red core for massive damage.

• Avoiding Damage: Stay behind cover, hide in buildings or foliage, and avoid standing directly in its line of sight.

When playing solo, patience and control of the battlefield are key. The best approach is to position yourself inside a building, hallway, or any area with clear exit routes. Once the Bastion completes its minigun burst, you can safely target the yellow leg joints or rear canister, maximizing damage while minimizing risk. Constant movement is crucial even high DPS won’t save you if you stay exposed in the open. Successful solo engagements require timing, precision, and understanding the Bastion’s attack rhythm.

How to Kill Bastion

Step 1: Find Cover

Always start near a doorway, wall, or other structure. Open areas are a death trap against Bastions.

Step 2: Lure & Stun

Attract the Bastion’s attention with a shot. Focus on the yellow leg joints or rear canister to stun it. Destroying the canister exposes the red core the Bastion’s true weak point.

Step 3: Deal Damage

• Solo: Take consistent, measured shots from cover using heavy ammo, explosives, or precision weapons.

• Squad: Focus fire on the exposed red core after the canister is destroyed for a swift kill.

Step 4: Cheese Methods

• Nuclear Approach: Stick Trigger Grenades to the Bastion for near-instant kills. Perfect for high value solo raids with minimal risk.

• Stealth Approach: Wait until the Bastion is isolated (typically last 5 minutes on the raid clock), engage quietly, and retreat via the nearest hatch.

Step 5: Optional “Ride & Melee” Trick

• Bastions can be climbed using Snap Hooks or careful positioning.

• Stunning first with grenades makes this safer.

• From the top, melee or weapon attacks can be used. Dealing 50 damage from above unlocks Death From Above.

• This technique is a fun pro tip for speed farming and achievement hunting.

Solo Bastion Kill Strategy

If you’re tackling a Bastion solo and want to maximize efficiency, here’s a tried and tested loadout and approach used by PRO Raiders. First, make sure you’re prepared: bring two fire grenades (either Blaze Grenades or Fireball Burners), around 15 Impact Grenades it’s smart to craft or bring a few extras in case some don’t land and a heavy ammo weapon, preferably an Anvil, with at least 60 rounds to finish off the Bastion or handle any unexpected PvP threats. Don’t forget a hatch key for a quick extraction and a Looting Mk2 if you want to optimize resource collection.

Once you’re fully loaded, head to high ground for the best vantage point. Start by tossing the two fire grenades at the Bastion to stagger it and deal initial damage. Then, unload your Impact Grenades directly onto its head or other vulnerable spots. With this method, even solo Raiders can take down a Bastion in under five minutes. The best part? This approach is cost effective the loadout usually runs around 27k, but you can walk away with 80k–100k worth of loot if you collect everything carefully.

With some practice, this strategy becomes second nature, letting you farm Bastion Cells and high value loot quickly while staying safe from other Raiders. Topside is dangerous, but with the right plan, you can dominate.

Best Weapons to Kill Bastion

Choosing the right weapon is crucial for efficiently taking down Bastion. Here’s a breakdown of the most effective options and their pros/cons:

Ferro

• Upgrade Ferro to Level 4 for one of the cheapest but still effective options.

• Pros: Reliable, good penetration for its cost.

• Cons: Only 1 shot per reload, and it has a long reload time, which can be punishing against Bastion.

Anvil

• Arguably the best weapon in the game right now.

• Pros: High damage revolver capable of one shotting most ARCs, 6 rounds per magazine, extremely versatile.

• Always go for Anvil if you unlock the blue print, or purchase from NPCs if available.

• Cons: None significant; the weapon is meta defining.

Hullcracker

• A special pump action 40mm grenade launcher using launcher ammo.

• Pros: Extremely high burst damage, great for quick takedowns.

• Cons: Very expensive and risky losing a Hullcracker can hurt your progress much more than losing Ferro or Anvil.

Where to Find Bastions (All Maps)

Bastions spawn across all maps, but some locations are more reliable than others. Knowing where to go drastically reduces time wasted hunting.

1. Dam Battlegrounds

• Northwest of Water Treatment Control

• Hydroponic Dome Complex Area

• Southwest of Power Generation Complex

This map tends to spawn fewer high-tier enemies, so Bastions appear less frequently. If you stumble upon one here, make the most of it. Don’t rush; patience is key.

2. Buried City

• Old Town Area

• East of West Village

Buried City offers moderate spawn consistency. Buildings provide elevation and cover, allowing you to safely pick off Bastion weak points while minimizing risk.

3. Spaceport

• South & East of Control Tower A6

• Southeast of Rocket Assembly

• Southwest of Launch Towers

• East of Shipping Warehouse

The multiple spawn points make Spaceport a great location for hunting Bastions. Use structures around Rocket Assembly for cover, taking advantage of choke points to control engagement.

4. The Blue Gate

• North of Ancient Fort

• West of Warehouse Complex

This map has consistent Bastion spawns. Garages, warehouses, and narrow pathways let you funnel them and control the fight even if you’re solo.

5. Stella Montis

• Landing Bay

Hands down the most reliable spawn in the game. Upper-level vantage points allow safe long-range attacks while Bastions struggle to reach you. If you want consistent Bastion Cells, Stella Montis is your best friend.

Pro Tip: Always scout ahead and plan your escape route. Even if you’re confident in your DPS, Bastions punish overconfidence with their minigun bursts.
