All Vault Hunter’s Guide to Kairos Locations in Borderlands 4

There are twelve different Vault Hunter’s Guide to Kairos collectibles. Compared to other items like Marcus Bobbleheads, which number over 200 and aren’t marked on your map, these guides are limited. For example, while you might find dozens of Bobbleheads hidden everywhere, there are only twelve Vault Hunter’s Guides in the whole game.

Unlike the Survivalist Caches, which are all in one area called Fadefields, these guides are spread all over Kairos, from the start to the final location. When you pick up each guide, it will give you experience points (XP), materials for your SDU upgrades, and play a recording from Arjay, your unfortunate companion from the story’s beginning. These recordings give you insights into Kairos and help develop the story further.

Be sure to check your map often as you do side quests. If you’re having trouble locating any Vault Hunter’s Guides, use the in-game pathfinding feature once the icon shows up on your map to guide you closer to the device.
