Horizon Forbidden West All Cauldron Locations and Machines Unlocked

A complete guide to all Cauldron locations, machine overrides, objectives and rewards in Horizon Forbidden West.

Horizon Forbidden West Cauldron

Horizon Forbidden West Cauldrons are very important when you want to override machines or use the machines as mounts.

Cauldrons are shown on your map by blue triangles, but you won’t know much about them until you get close enough to see them, and once completed these triangles turn green.

Each of these Cauldron locations is filled with challenging climbing puzzles, and each one must be completed with a boss battle in order to obtain the rewards they hold. To get through it all you’ll build up a large collection of Horizon Forbidden West machines that you can ride or get to help you fight.

To begin with, however, you must track down where they may be hidden. So here are the locations of all the Horizon Forbidden West Cauldrons in the game, as well as the rewards you’ll receive when you complete them.

What are Cauldrons in Horizon Forbidden West?

Cauldrons in Horizon Forbidden West are like special dungeons. They resemble underground dungeons, complete with hostile machines and parkouring parts to get through.

The ability to override new machines is one of the many benefits of clearing a Cauldron. New Machine Overrides are unlocked after successfully overriding the Cauldron Core. To be able to override a machine means you can tame them, some of the smaller machines can then be employed as mounts, while the larger ones will assist you in combat situations.

How Machine Overrides Work in Horizon Forbidden West

A full machine override from a Cauldron may not always be available, as some Cauldrons offer a mix of ready-to-use and crafted overrides. Using parts from the relevant machine, the craftable overrides can be done at the fabrication terminal back at the base.

So this means that in order to fully override some machines, you still have to take down a couple of them, even after you have completed the Cauldron mission, to be able to craft and fulfill its override requirement.

How many Cauldrons are there in Horizon Forbidden West?

Horizon Forbidden West contains a total of Six Cauldron locations. Even after completing the story, you can still find all of the Cauldrons in exploration mode.

  1. Repair-Bay TAU Cauldron
  2. GEMINI Cauldron
  3. MU Cauldron
  4. IOTA Cauldron
  5. CHI Cauldron
  6. KAPPA Cauldron

The first two Cauldrons are derived automatically from the main story (6th and 14th Main Quest). The most effective technique is to play through the story first, and then clear up any lingering Cauldrons after that.
