Order Bunkers are a type of Activity in Borderlands 4 that unlocks after completing the One Fell Swoop Main Mission. See all 6 Order Bunker map locations and the rewards for clearing Order Bunkers.
List of Contents
There are a total of 6 Order Bunkers in Kairos. You will be able to access them after completing the One Fell Swoop Main Mission.

Order Bunkers can only be accessed after completing the One Fell Swoop Main Mission. This is one of the branching Main Missions that becomes available around level 13–16, following the fourth Main Mission: A Lot to Process.

If you discover an Order Bunker early, you'll receive a “You shall not proceed” notification indicating that the area is currently off-limits. The location will then be marked on your map and can be revisited later once the unlock conditions are met.
Clearing an Order Bunker for the first time rewards you with 40 SDU Tokens. These tokens can be used to purchase storage upgrades for your Ammo, Backpack, Bank, or Lost Loot capacity.
Each Order Bunker contains a unique boss that drops a variety of high-quality gear. These bosses also have a chance to drop unique Legendary Weapons and other Legendary items.
