The builder tool is designed to construct habitats capable of withstanding extreme environmental conditions.


― PDA, Dialogue


The Alterra handheld Habitat Builder is a tool crafted using the Fabricator.


The Habitat Builder allows the player to build a variety of stationary items. It is a crucial tool for the deployment of Seabases and the customization of the interiors of both Seabases and the Cyclops.

The Habitat Builder requires a Battery to operate, and objects cannot be constructed/deconstructed if the battery is depleted.

If a Bleeder latches onto the player's arm, the player can use the Habitat Builder to hit the Bleeder.

How to Use

  1. RMB to open the Habitat Builder menu
  2. Select the desired tab: Base Pieces, Exterior Modules, Interior Pieces, Interior Modules or Miscellaneous
  3. Select an item
  4. Point the Habitat Builder at wherever the item should be placed until an outline appears
  5. Use Up and Down Mousewheel to rotate object. (if applicable)
  6. Press LMB to place the outline
  7. Continue building the item by holding the LMB
  8. Done.
  9. Placed items can also be deconstructed by pointing the Habitat Builder at them and holding Q, this only applies if the text "Hold Q to Deconstruct" appears on the screen. This also gives back all resources used in the building process.

Data Bank Entry


The Alterra handheld habitat builder has been an essential tool of xenoscientists, colonists and emergency relief crews across 11 different trans-govs for more than 50 years.

  • Habitat modules are hermetically sealed from the outside environment
  • Build on land, underwater, or in a vacuum
  • Habitats can be enhanced to become long-term homes, remote research stations, defensive outposts and more

Quick Start Guide:

  1. Select the basic compartment from the builder menu and place it somewhere opportune
  2. Add a hatch to access the compartment
  3. Build a solar panel to power the habitat's oxygen generator
  4. Construct useful interior modules like radios, rechargers and storage solutions

Primary habitat systems like oxygen generation and flood control, as well as modules like the fabricator draw power and will not function without it. Additional compartments reduce overall hull integrity, depending on the external pressure.

  • The idea for the Habitat Builder may be taken from Natural Selection 2, where the Builder is used to create various machinery, much like Subnautica's.
    • And thus, the Habitat Builder's former name was the Builder.
