Aloy breaches the forbidden factory to uncover the truth behind the machines.

The infiltration of Cauldron SIGMA marks the first time Aloy breaches the forbidden factories where machines are manufactured. Directed by the enigmatic Sylens, this mission serves as a critical turning point in her quest to understand her own heritage and the true history of the world. While the Nora tribe fears these structures as cursed places, Aloy discovers they hold the keys to the past.

Lore & Background

Inside the core, Aloy accesses digital archives that reveal the Cauldron's role in machine production, but the data does not detail the Faro Plague or the extinction event—those revelations come later, primarily at the Zero Dawn facility. The information sets her on a path to uncover Project Zero Dawn, revealing that she is not just an outcast, but part of a larger plan for survival.

In Their Own Story

Steam hissed from the rusted vents as Aloy crouched in the shadows, her bow drawn tight against the gloom. The air smelled of ozone and ancient oil, foreign to the natural scents of the mountains she called home. Above, metal footsteps clanked rhythmically—a Stalker patrolling the catwalks. She held her breath, watching the red eye of the machine sweep past her hiding spot before slipping silently into the maintenance corridor.

Reader's Guide

Sylens approaches Aloy after her initial trials and reveals that machines are manufactured in hidden facilities known as Cauldrons. He instructs her to infiltrate the nearest one to retrieve data regarding their origins. Aloy travels to the restricted zone, navigating through hostile terrain while avoiding detection by patrolling units. She utilizes stealth tactics and combat skills to neutralize threats like Watchers and Stalkers guarding the entrance. Upon reaching the central core, she interfaces with a terminal using her Focus device. This download reveals logs about the First Ones and confirms the existence of the Faro Plague that destroyed civilization centuries ago. The mission concludes with Aloy escaping the facility, now armed with knowledge that challenges tribal dogma. This event deepens her partnership with Sylens while fueling her determination to find the truth about her own creation.
