Marguerit Maida is one of Subnautica: Below Zero’s most compelling characters — a survivor from the original Subnautica games who has been living alone on Planet 4546B for years, adapted to its hostile environment in ways that border on the extraordinary. Her story arc, centred around the Omega Lab, is one of Below Zero’s most emotionally satisfying elements if you approach it in the right order and take the time to find all of her encounters. This guide covers the Marguerit Maida and Omega Lab story route without heavy spoilers.
Who Is Marguerit Maida?
Marguerit Maida is a survivor from the original Subnautica’s ISOC crew. She survived the crash of the Aurora and the events of the first game, but unlike the unnamed survivor of the original, she chose to remain on Planet 4546B rather than escaping. By the time Robin arrives in Below Zero, Marguerit has been living alone on the planet for years — surviving the Leviathans, the cold, and the isolation through a combination of extraordinary competence and iron will.
She is initially suspicious of Robin and hostile to Alterra Corporation, which she blames for the deaths of people she cared about. Her warming relationship with Robin over the course of the game is one of Below Zero’s best narrative threads.
Finding Marguerit: Encounter Locations
Marguerit cannot be found in one place — she moves across the world and you encounter her in different locations as the story progresses. Her first appearance is at her Delta Station homestead, which you can discover relatively early by exploring the Delta Station area thoroughly. Subsequent encounters take place at the Omega Lab (her primary base of operations) and at other locations tied to the story’s progression. Pay attention to her radio communications — she often signals Robin before appearing in person.
The Omega Lab
The Omega Lab is Marguerit’s fortified base — a sophisticated installation that demonstrates her years of survival experience. Finding it is a significant gameplay milestone and unlocks story content that contextualises the events of Sam Ayou’s investigation. The Omega Lab is located in a moderate-depth area accessible with a well-equipped Seatruck. Navigate to the Thermal Lily biome region and follow Marguerit’s signals when she broadcasts them.
Story Implications Without Spoilers
The Marguerit storyline connects directly to Robin’s investigation of her sister Sam’s death. The information at the Omega Lab significantly reframes the early-game events and adds moral complexity to the corporate storyline. The relationship between Marguerit and Robin’s sister Sam is revealed progressively, and each new piece of information lands harder if you have been engaging with the audio logs and database entries throughout the game. Do not skip the database reading.
