When traversing many new environments and creatures in Subnautica: Below zero, explorers must build a foundation for themselves. Here, they can store all the necessary resources extracted from the environment. In addition to relying on oxygen supply, deep-sea explorers also need a continuous source of food. For Subnautica players, this is done through the use of “Alien Containment” unit.
Like the previous title Subnautica: Below Zero, players are free to explore, analyze and categorize almost everything they find. This includes several different types of passive and aggressive flora and fauna. The alien containment unit is like a huge aquarium, where players can display and raise biological samples found outside the base.
To access the “Alien Containment unit”, the player will need to unlock the blueprint for the item. These can be found by scanning the alien containment fragment located in the Bow of the Mercury II wreck. Here, players can also find the three pieces required to unlock the blueprint for the parallel processing unit. But first, they must have built a laser cutting machine.
After unlocking the blueprint, players will be able to use the “Habitat Generator” to build an alien containment unit. The formula requires the use of 5 X glass and 2 X titanium. This item can be installed in large rooms or multi-purpose rooms. If two or more rooms are stacked on top of each other, placing a unit in both rooms will cause them to merge into a larger unit. This will also increase the tank’s capacity by 10 for each additional Alien Containment unit stacked.
To increase the types of flora and fauna, players need to build a hatch in the “Alien Containment” unit to enter the tank. Once in, the player can release fish and biological eggs by removing them from their inventory. A single tank can hold up to 10 fish. Players should avoid making tanks that are too large, because overcrowding will prevent their specimens from multiplying.
Adding more fish may also cause the death of tank inhabitants. You can add plants using the Planter at the bottom of the unit. When the unit is built in a multi-purpose room, the planter can hold up to 16 flora. When in a large room, the planter can accommodate up to 32 slots. Now, “Subnautica: Below Zero” players can ensure that they continue to provide the necessary resources to maintain Deep Blue’s survival, and they can turn their attention to exploring the many mysteries of these waters.
