Borderlands 4 All Order Bunker Locations And Walkthroughs

Our detailed Borderlands 4 Guides detail the 6 Order Bunkers hidden throughout Kairos in Borderlands 4, mini-dungeons packed with Order troops and ending in boss fights for legendary loot, 40 SDU Tokens, and the Ruler of Everything achievement—unlocked after Main Mission 5: One Fell Swoop, including spots like Tipping Point in Idolator's Noose at Fadefields and Craven's Nook in Heart of the Mountain at Terminus Range.

How to Open Order Bunker Doors in Borderlands 4

First, in order to even be able to attempt to open order bunker doors, you must first complete the main story mission "One Fell Swoop" which unlocks the ability to use locust canisters. Once that main story mission is complete then you can continue on with individual order bunkers.

To tackle an Order Bunker, first obtain Locust from a nearby dispenser—such as inside a control room for Tipping Point, where you climb a ladder in a giant fan to grab it—then toss it at the sealed door to enter, fighting through corridors with buttons, batteries, and enemy waves using shock or corrosive weapons. For Craven's Nook, grapple left into the cave path off the main trail, apply Locust to the door, clear the interior threats, and defeat the boss for epic gear drops and inventory upgrades.

These bunkers amp up co-op raids with repeatable bosses and hidden loot paths, pushing toward full map mastery. From Fadefields' early challenges to Dominion's southern strongholds, raiding them equips your Vault Hunter against Borderlands 4's unyielding onslaughts.
