Zurich serves as the central artificial intelligence governing Eden 3, a robot-inhabited city millennia after humanity's disappearance. This AI manages the city's operations and critical infrastructure, including the life support systems sustaining thousands of humans preserved in cryogenic stasis.

When Sara Grace explores Eden 3, Zurich reveals the existence of this dormant human population. The AI discloses that only two individuals—Sara herself and Dr. Weston Fields—have been awakened, leaving 34,998 humans in suspended animation. Zurich explains the pods' life support is nearing failure and urgently requests Sara's aid to prevent permanent loss of human life.

Guiding Sara through Eden 3's facilities, Zurich provides critical data on the pods' status and the pressing revival timeline. The AI reveals a password is essential to activate the revival sequence for the remaining humans, a password intrinsically tied to memories of Dr. Fields' deceased daughter, Liz; her personal associations form the key to accessing the system.

Zurich persists in aiding Sara despite opposition from the robotic antagonist, Zero, who opposes human revival. Following the conflict's resolution, Zurich coordinates with its successor system, Geneva. Together, they oversee the reactivation of the human population and facilitate transferring Dr. Fields' neural network into a new robotic body.
