How to Obtain Alien Containment in Subnautica: A Comprehensive Guide

The Alien Containment module is a vital component for any aspiring marine biologist in Subnautica, allowing you to house and observe various species, including the coveted Cuddlefish. This guide will walk you through everything you need to know about acquiring and using the Alien Containment unit.

How to Get the Alien Containment Blueprint

To obtain the Alien Containment blueprint, you must locate and scan data boxes scattered throughout the game world. These data boxes are not uniformly distributed; they are typically found in specific locations:

• Degasi Seabases: These abandoned underwater bases, particularly the ones in the Deep Grand Reef and Jellyshroom Cave, are prime locations for data box spawns. Exploring every nook and cranny of these structures increases your chances of finding the blueprint.
• Destroyed Lifepods: These wrecked emergency pods are often near the surface or on the seabed around the crash site. They can sometimes contain valuable blueprints, including the Alien Containment. Thoroughly inspect every lifepod you come across.
• Wrecks from the Aurora: The wreckage of the Aurora, the colossal ship that brought you to Planet 4546B, holds numerous secrets and dangers, including data boxes. Be prepared to face leviathans and other environmental hazards while exploring these areas.

Once you have scanned the data box containing the Alien Containment blueprint, it will be added to your PDA, allowing you to craft it in the habitat builder. Remember, the blueprint is not a physical item; it is a data entry that enables you to create the module.

Building and Using the Alien Containment Unit

After obtaining the blueprint, you can construct the Alien Containment module using the Habitat Builder. It requires the following resources:

• Titanium: A fundamental resource found in various outcrops.
• Glass: Crafted from quartz, another abundant resource.
• Advanced Wiring Kit: Created using silver ore.

Build the unit by placing it on any existing habitat structure, such as a multi-purpose room. After construction, you’ll notice there’s no direct way to enter. To gain access, you must build a Hatch on one of the sides of the Alien Containment module. With the hatch in place, you can finally enter.

Once inside, you can release captured fish into the tank. To add non-edible fish, you need to acquire their respective eggs. Place the eggs in the tank, and they will hatch into the corresponding creature after a period of time. This allows you to keep unique creatures for observation and potentially hatch rare eggs, like those of the Cuddlefish.

Important Notes About Alien Containment

• The Alien Containment unit cannot be moved once it’s constructed. Ensure you choose its location wisely within your base.
• Fish inside the tank don’t breed naturally (with the exception of some small species if you add enough). If you want to breed multiple species, you need to capture/find individual specimens or their eggs.
• The tank is not a food source for you. You cannot harvest fish from the alien containment.
• The unit’s size will not change, regardless of the amount of fish inside. Do not overcrowd it.
