Cauldron ZETA is a location and activity in Horizon Zero Dawn.


Cauldron ZETA is a HEPHAESTUS facility that manufactures machines for use in terraforming.


Zeta's entryway differs from other Cauldrons in that the primary entrance is sealed and guarded by multiple Stalkers. The true entrance is above and to the left, guarded by a single Redeye Watcher.

The interior is similar to other Cauldrons, but lacks any sort of puzzle or enemies until you reach the core. The core will house a Thunderjaw being assembled, with two Watchers guarding it. The Thunderjaw will attack upon being released.



  • In its corresponding datapoint, this Cauldron is referred to as Cauldron THETA.
