All Order Bunkers Legendary Loot & Bosses in Borderlands 4

There are a total of 6 Order Bunkers in Borderlands 4, and each of them provides players with a unique boss encounter and a plethora of potential Legendary loot to be farmed. Order Bunkers are unique activities in which players must find a Locust station to unlock the main bunker door, which is why we’ll show you how to open every Bunker in Borderlands 4, along with what boss fight players will face in each of these Bunkers, and the Legendary loot that can be farmed from these locations.

Blacklime Bunker

How to Enter Blacklime Bunker & Beat Core Observer

• Location: The Howl, the Fadefields

At Blacklime Bunker in The Howl, Fadefields, players will need to first open the door. To do so, stand on the rocky platform closest to a rock with a tree, and then jump across. From the lower platform, you should be able to double jump and mantle. Once on this platform, you will find a Locust station that can be tossed to the door, so you can then glide over to it and walk through. Follow through the bunker to find a gap between the floor and a pipe, where you can crouch through, to then venture across a flooded room to find the Core Observer. This boss fight has a Shield, then Armor, and a final Shield. As such, it’s advised to use Shock weapons and Corrosive/Cryo weapons.

Tipping Point

How to Enter Tipping Point & Beat Mimicron

• Location: Idolator’s Noose, the Fadefields

Tipping Point can be confusing for most players who venture to this Bunker located at Idolator’s Noose in the Fadefields, but the solution to open Tipping Point’s door is relatively simple. With your back to the door, head to the right to locate a giant fan. Inside the giant fan, take another right to climb a ladder, where you will find a Locust station. Drop down from the hole in the floor at toss the Locust at the door. Through the bunker, players are required to open additional doors by locating buttons and batteries, which are all in the same room together. At the boss fight itself, players face off against Mimicron. This unique boss creates Shielded copies of itself, and the main boss has a Shield and then Armor, so Shock and Corrosive/Cryo are advised.

Craven’s Nook

How to Enter Craven’s Nook & Beat Callous Harbinger of Annihilating Death

• Location: Heart of the Mountain, Terminus Range

Craven’s Nook requires players to venture into the Heart of the Mountain in Terminus Range (pictured above). This location can be easily found by following the cave’s path, but be sure to veer off to the left as soon as you are able to grapple to a platform. Keep on this left path, and you will face the Bunker door. To access Craven’s Nook, look at the door and turn left, where, on a rock below the cliff, is the Locust station (also seen above). Inside the bunker, there will be a vent that can be yanked open on the left wall. Climb through, and continue on to climb an elevator shaft and grapple up the platform to find the boss, Callous Harbinger of Annihilating Death, who has a large Shield and an Armor bar, so again, use Shock and Corrosive/Cryo weapons.

The Wireworks

How to Enter Wireworks & Beat The Divisoner

• Location: The Low Leys, Terminus Range

The Wireworks can be found in the Low Leys area of Terminus Range, and accessing the door is far simpler thank most Bunkers. Follow the snowy path until you reach a cliffside, and then glide towards the next rock that allows you to then glide to the Bunker entrance. Players can then climb up the platforming wall, and then look down the wall you just climbed to find the Locust station to grapple it and throw it at the door. The bunker is pretty simple, just follow through to the right to find a vent on the floor that can be yanked open. Jump down, then look to the left side of the large room to press a button to push forward to find the Divisioner boss. This boss has a Shield, but it’s a trick, as every time it’s destroyed, it will summon a Rendition, which is a smaller copy of itself. Destroy the Renditions (who have Shield health bars, so use Shock), to destroy the Divisioner’s Armor health bar, and kill it without spawning too many Renditions.

The Crawlcroft

How to Enter Crawlcroft & Beat Fractis

• Location: Grindstone of the Worthy, Carcadia Burn

The Crawlcroft is located within Carcadia Burn, specifically in Grindstone of the Worthy. Players will be able to locate this bunker by following the map above and veering to the right into an Order base. Within the base, there’s a cave that can be followed through to discover an Order Bunker within. To open the Crawlcroft Bunker, head opposite the main door to find the Locust station underneath some metal bars, directly below the grapple platform. Take this Locust, and throw it at the door to continue through. There aren’t many mechanisms for this Bunker, so simply follow through the half-open doors and crouch through the gaps in the wall, and follow through to the left side until you eventually reach Fractis. Fractis is more intimidating than he looks, as he will summon a golden version of himself with a Shield, so erase it with Shock, then finish him off with his Flesh bar that’s weak against Incendiary.

Ironwall Resolve

How to Enter Ironwall Resolve & Beat Directive-O

• Location: Terminus District, Dominion

In order to open Ironwall Resolve, players must first have access to Dominion. They must then head to Beth located at Lakeside Properties in the Fades District of Dominion, and complete her side mission: One Gassy Issue. With that side mission completed, head to the Terminus District of Dominion to find the Ironwall Resolve in the Praetor’s Lecture. Before heading up the stairs to the Ironwall Resolve door, look to the left to find a Locust station amidst a pile of trash, which can then be carried up the stairs and thrown at the door. The Bunker here can be pretty complex, so just go through the open rooms and platform through to deactivate the forcefield, and repeat in the opposite room to unlock the boss room to fight Directive-O. This boss isn’t that much of a threat, so destroy the Shield bar with Shock and the Armor bar with Corrosive/Cyro.
