How to craft the Habitat Builder in Subnautica 2

Before you can construct structures, you must craft the Habitat Builder. This process begins with gathering basic resources. You first need a Survival Multitool, which requires three pieces of titanium, and a Scanner, which requires two titanium, two quartz, and one basic battery. Titanium is found abundantly in the immediate vicinity of your Lifepod, while quartz can be harvested to create glass. Copper, necessary for batteries, is found in nearby caves.

Once you possess the Multitool and Scanner, you must locate two damaged Habitat Builder tools to scan. At In Game News, we have identified these specific locations to assist your progress. The first tool is inside a metal box located directly next to the "Welcome Center" sign outside the facility. The second tool is found inside the building; you must dive into the central floor hole and search the metal storage container positioned next to the Oxygen Tunic.

Scanning the two Habitat Builder tools mentioned above provides the data required to unlock the item in your Fabricator. After scanning both, the recipe for the Habitat Builder becomes available. To craft it, you will need to combine two titanium, one glass, one basic battery, and one copper wire. Once crafted, this tool serves as your primary interface for placing corridors, doors, and essential utility machines like the Fabricator.

How do you start building a base in Subnautica 2

Once the Habitat Builder is in your inventory, you can initiate construction. The game provides a guided introduction to these mechanics through a NOA entry found within the Welcome Center. This structure is located 80 meters southeast of your starting Lifepod. Upon arrival, you will find the building lacks power. By inserting a basic battery into the wall panel, you activate the Bio Lab and the NOA system, which provides a walkthrough of the construction interface.

With the tool equipped, you can open the build menu to view available structures. This includes modular corridors, entry hatches, and various internal components. The system allows for the placement of production machines, such as the Fabricator, which is vital for crafting advanced gear. Decorative items are also available to customize your living space. Ensure you have sufficient resources, specifically titanium and copper, before attempting to build larger structures to avoid running out of materials mid-construction.

The variety of blueprints available in Subnautica 2 ranges from structural components to quality-of-life furniture. Structural blueprints allow for the creation of rooms and corridors that protect you from the environment. Utility blueprints, such as those for the Fabricator, are unlocked automatically or through scanning environmental objects within the Welcome Center and surrounding wreckage.

Furniture blueprints are often found as part of the interior design modules within abandoned facilities. As you explore, prioritize scanning any interactive objects or consoles. This ensures you have the maximum number of options when designing your base.
