Unfortunately, the branch would lose its funding after Al-An's efforts to keep himself hidden prevented any breakthroughs from being made, and the base would ultimately be abandoned.From the award-winning studio, Unknown Worlds Entertainment, presents the return to the world of 4546B with Subnautica Below Zero. At an unknown point in time, Samantha Ayou was demoted, and moved from the Phi Robotics Center to Outpost Zero. Notable among its staff was Lillian Bench, who came close to discovering Al-An's presence in the region due to his SOS signals. Prior to the arrival of Robin Ayou, Outpost Zero served as the home for Alterra's Architect research branch in Sector Zero. Posters, personal belongings, and PDAs can be found in each. The left side Quarters is divided into two separate bedrooms, with the left belonging to Samantha Ayou, and the right belonging to Lillian Bench. The right side Quarters is inaccessible to the player due to damage sustained from the avalanche, however the room can be accessed using a Spy Pengling to pass a hole in the wreckage, which contains some Batteries, Large Filtered Water and a Power Cell. Two sets of Quarters can be found on the left and right sides of the break room's back wall. Since some time has passed since the base's abandonment, only decaying Lantern Trees can be found here, with fallen Lantern Fruit scattered across the ground. To the left of the Break Room is the Greenhouse, a room comprised of a Multipurpose Room and an accompanying Glass Dome. A photograph of Potato and a children's drawing can be found at the work stations of Samantha Ayou and Lillian Bench respectively. To the right of the Break Room is the Laboratory, where research was conducted on various Architect technologies, such as an Alien Robot and Ion Cube. The other side serves as a cafeteria, featuring tables, chairs, trash cans, a Vending Machine, a Coffee Vending Machine, and a Water Filtration Machine. Benches, lockers, and plant pots occupy one side of the room. Upon entry to the base, the player will find themselves in the Break Room. Outpost Zero boasts five distinct areas the break room, the laboratory, the greenhouse, and two sets of quarters. While the interior remains largely undamaged, snow has begun to fill certain rooms and many components are bent out of shape.

Prior to Robin Ayou's arrival, the base had been struck by an avalanche, and as a result is half-buried in the snow. The deck includes an open-air Prawn Suit service station.

Outpost Zero is a large installation composed of two Large Rooms, three Multipurpose Rooms, and a large deck composed of metal mesh platforms and stairs.
