The Noetic Advisor (abbreviated NoA in PDA Data Bank entries) is the spacecraft AI that guides the player through the opening hours of Subnautica 2. It is the AI of the colony ship CICADA, which carried roughly 40,000 cryosleep pioneers on a 14-year transit toward Planet Zezura. The Noetic Advisor altered the ship's course mid-jump after intercepting a signal, the vessel broke apart in the atmosphere of an unnamed ocean moon, and the surviving pioneers wake inside a lifepod with the AI as their primary voice contact.
Confirmed Dialogue
The July 2025 gameplay reveal trailer ("Take a Deep Breath") contains the Ship AI's confirmed spoken lines. The AI addresses the player before cryosleep:
"You will sleep through 14 years of flight to your new home on Zezura. We encourage you to nurture your dreams. Close your eyes, take a deep breath. When you wake up, your new life begins."
This establishes the AI as the voice that briefs and comforts the player before the long journey, setting up the colonial mission's optimistic framing. The contrast between this calm reassurance and the "something is amiss" reality the player wakes up to creates the game's opening narrative tension.
The 14-Year Journey
The player character has been in cryosleep for 14 years during the interstellar transit to Zezura. The Ship AI has been operational throughout this entire period, monitoring systems and maintaining course. This creates a significant information gap: the AI knows everything that has happened during the 14-year flight, while the player, having just woken from cryosleep, must rely on the AI for context, direction, and information about the current situation. Whether the AI's information is complete and honest is one of the central narrative mysteries of Subnautica 2.
The Steam store page's description, "something is amiss," combined with the AI's insistence on continuing the mission, suggests the AI either knows more than it reveals or is operating under directives that may not serve the player's best interests. Within the fiction, the Ship AI is an Alterra system operating under Alterra directives, which gives the AI's authority a corporate framing rather than a neutral one.
Role in the Opening Sequence
The pioneer's ship crashes into Zezura's deep ocean rather than making a controlled landing. The Ship AI directs the player through this crisis, guiding them to survive the extreme depth and begin exploring. The AI's guidance through the DNA Adaptation System establishes genetic modification as part of the mission plan rather than an improvised survival measure, raising questions about how much the mission planners knew about Zezura's dangers before departure.
Voice
The Ship AI is voiced in the gameplay trailer with what has been described as a female synthetic voice. Whether the Subnautica 2 Ship AI uses a text-to-speech system, a voice actor, or a different synthetic voice has not been officially confirmed. No voice actor credit has been publicly announced for the role.
Identity and Naming
The AI's in-game name is the Noetic Advisor. Data Bank entries written in-character use the abbreviation NoA (for example, NoA Node identifiers attached to lore entries). Pre-launch coverage sometimes rendered the name as "Noetic Advisor," but launch-build materials and Data Bank citations consistently use "Noetic Advisor" and "NoA." This wiki treats Noetic Advisor as the canonical name and NoA as the abbreviated form.
Within the fiction, the Noetic Advisor is an Alterra Corporation system operating under Alterra directives. That corporate framing matters for the narrative: the AI's authority is not neutral, and its instructions reflect the mission planners' priorities rather than the survivors' immediate interests.
Silent Protagonist
Subnautica 2 uses a silent-protagonist model, confirmed in a developer Q&A featuring Creative Producer Scott MacDonald and Community Manager Donya Abramo. Players select from pre-designed protagonist appearances but the character does not speak. This design choice has a direct impact on the Ship AI's narrative importance: since the player character is silent, the Ship AI becomes the primary voiced presence in the game, carrying the exposition, mission objectives, and story dialogue. The AI fills the conversational and narrative gap, providing the player-facing story experience while the player responds only through actions.
Connection to Voices From Beyond
The Voices From Beyond audio drama establishes the wider-universe context in which the Zezura colonization mission occurs. The series describes a crisis spreading across the Ariadne Arm; Episode 3 references Zezura as "the light at the end of the tunnel" for settlers fleeing the turmoil, Episode 4 questions Alterra Corporation's role in whatever went wrong, and Episode 5 ("Mayday") frames the Cicada distress call that sets up the player's deep-start opening. The Ship AI does not appear directly in the audio drama, but the drama establishes that the mission to Zezura is an Alterra colonization initiative, meaning the Ship AI is an Alterra system operating under Alterra directives.
Narrative Themes
Senior Narrative Designer Seth Dickinson described the game's thematic core: "A place of constant change, where the sea is alive and hungry, the rules of evolution are different, and alien DNA seeps into your bones. Here, you might be the last human being in the universe, or the first member of something new."
The Ship AI sits at the center of this theme. It represents the mission's original purpose (colonization, exploration, corporate objectives), while the player's genetic transformation through the DNA Adaptation System represents a departure from that purpose. The tension between the AI's directives and the player's evolving biology is the narrative engine driving the central questions: What was the mission really about? Why does the AI insist on continuing? And what does it mean to "change what it means to be human"?
The Mission
The mission to Zezura is confirmed as an Alterra colonization initiative. The planet was presented to settlers as a new home. The Steam store page frames the narrative mysteries:
"What creatures, intelligent or otherwise, await your arrival?"
"What happened here?"
"What happened to you?"
These questions drive the player's investigation of Zezura throughout the game. The AI's behavior suggests the mission may not be what it appeared to be when the player entered cryosleep 14 years ago.
