When traversing the many new environments and creatures found in Subnautica: Below Zero, it is essential for explorers to establish a base for themselves. Here, they can store all the necessary resources that they’ve harvested from their surroundings. In addition to a reliant oxygen supply, deepsea explorers also require a continuous source of food. For Subnautica players, this is accomplished through the use of the Alien Containment unit.
As with its previous title, Subnautica: Below Zero allows players the freedom to explore, analyze, and categorize nearly everything they come across. This includes several different types of both passive and aggressive flora and fauna. The Alien Containment unit acts as a huge aquarium tank where players can display and raise samples of the organisms found outside their base.
Alien Containment Location
To gain access to the Alien Containment unit, players will need to unlock the item’s blueprints. These can be found by scanning the Alien Containment fragment located in the Bow of the Mercury II wreckage. Here, players can also discover the three fragments needed to unlock the blueprints for the Parallel Processing Unit. But they’ll need to have crafted a Laser Cutter first.
Once the blueprints are unlocked, players will be able to construct an Alien Containment unit by using the Habitat Builder. The recipe calls for 5x Glass and 2x Titanium. This item can be installed in a Large Room or a Multipurpose Room. In cases where two or more of these rooms are stacked atop one another, placing a unit in both rooms will cause them to merge into a single, larger unit. This will also increase the capacity of the tank by 10 per additional Alien Containment unit stacked.
In order to add flora and fauna, players will need to build a hatch onto the Alien Containment unit for entry into the tank. Once inside, players can release fish and creature eggs by dropping them from their inventory. A single tank can hold up to 10 fish. Players should avoid creating over-capacitated tanks, as overpopulation will halt further reproduction from their specimen.
Adding more fish can also lead to the death of the inhabitants of the tank. Plants can be added using the Planter at the base of the unit. When the unit is built in a Multipurpose Room, the Planter has up to 16 slots for flora. When in a Large Room, the Planter can have up to 32 slots.
Now that Subnautica: Below Zero players can ensure a constant supply of the resources necessary for surviving the deep blue, they can focus their attention on exploring the many mysteries of these alien, arctic waters.
Subnautica: Below Zero is currently available for the PC, PlayStation 4, PlayStation 5, Switch, Xbox One, and Xbox Series X/S.
