Venture into the war-torn landscapes of Kairos in Borderlands 4, and you’ll soon discover the imposing, sealed doors of Order Bunkers. These fortified strongholds are a premier endgame activity, offering a thrilling alternative to other farming methods like Auger Mines. But gaining access isn't always straightforward. This comprehensive guide will walk you through every step required to open Order Bunkers, locate the essential key items, and claim the legendary rewards hidden within.
What Are Order Bunkers?
Order Bunkers are extensive, multi-chambered mini-dungeons designed for high-intensity combat and exploration. Unlike the straightforward arenas of Ripper Drill Sites, each bunker features a unique, labyrinthine layout filled with hordes of Order soldiers, challenging environmental puzzles, and traversal sequences. The ultimate prize for clearing one is a confrontation with a unique boss enemy, who guards some of the most powerful dedicated loot in the game. These bunkers are repeatable and are a core part of any Vault Hunter’s loot-farming routine.
Prerequisite: How to Unlock the Ability to Open Bunkers
You cannot simply walk up to an Order Bunker and enter at the start of your journey. Access is gated behind main story progression. To acquire the necessary tools, you must first complete the campaign mission
“One Fell Swoop.”This pivotal mission, the fifth in the sequence, takes you to the Fadefields to assault a major Order facility. The narrative focus is on uncovering intel about Indomitus Sol's devastating bioweapon. More importantly for loot hunters, successfully finishing this mission introduces you to the
Locust Canister—the only tool powerful enough to breach the armored doors of Order Bunkers. Consider this mission your formal key to unlocking this endgame activity.
Step-by-Step: How to Open an Order Bunker Door
Once “One Fell Swoop” is complete, you’re ready to crack open any bunker you find. The process involves two key steps:
Locate the Locust Canister Dispenser: Every Order Bunker has a dedicated dispenser unit stocked with LocustCanisters somewhere in its immediate vicinity. However, Gearbox Software has cleverly hidden these dispensers, turning the search into amini-puzzle. They are never inside the bunker itself but are alwaysaccessible in the surrounding area.- Example: The dispenser for the Tipping Point bunker might be hidden high above in a control room, requiring you to scale a massive ventilation shaft to reach it.
- Example: For the Blacklime bunker, you may need to look across a canyon to spot the dispenser perched on a distant rock formation.
Breach the Door: After retrieving a canister, target the bunker’s heavily fortifiedentrance and throw it. The canister’s corrosive payload will eat through the armor plating, causing the main door to shudder and retractautomatically, granting you access to the dangers and riches within.
CRUCIAL WARNING: The Locust Canister is on a short timer. You will hear a distinct,escalating ticking sound. If this ticking becomes rapid and frantic, the canister is moments away from detonating in your hands, so use itquickly!
What to Expect Inside an Order Bunker
Prepare for a intense, multi-stage fight. The interior of each bunker is a curated combat experience:
- You’ll battle through a series of interconnected arenas and corridors, clearing out waves of Order troops.
- Each bunker has a unique design, with different objectives, platformingsections, and enemy compositions, ensuring no two feel exactly alike.
- The finale is always a climactic boss battle against a powerful, namedenemy unique to that specific bunker. These bosses have an increasedchance to drop specific Legendary weapons, shields, class mods, andmore.
Farming Order Bunkers for Legendary Loot
The bosses inside Order Bunkers are fully farmable. If you’re searching for a perfect weapon roll, you can defeat the boss, exit to the main menu,and reload your game to challenge them again. However, note that youmust fully clear the entire bunker on each subsequent run; there is nodirect checkpoint at the boss room. The rewarding loot pool makes theeffort of replaying these mini-dungeons well worth it for dedicatedVault Hunters.
Now that you’re equipped with this knowledge, head to Kairos, track down thosedispensers, and start cracking open the Order’s most valuable vaults.Happy looting!
