Items are all the things the player find, catch, harvest, collect and craft in Subnautica.

The player can carry a limited amount of items in their inventory.

Every item has its own size from 1x1 inventory-slots to up to 4x4 inventory-slots. And also every item has a weight. The more items the player has stored in the inventory, the lower the swimming speed.

Also, items can be placed in various forms of storage.

Items fall under these main categories:

  1. Raw Materials
  2. Placeable Items
  3. Crafted Items
  4. Vehicles


  • When the game was first released, all of the in-game items were represented with cubes, which had a picture of the item printed on the sides.
