Hatch
The Hatch is the primary entrance and exit for Subnautica 2 seabases, allowing the player to enter and leave the base underwater without flooding the interior.
Quick Info
Description
The Hatch is your seabase's doorway. Mounted on the wall of a Corridor or Multipurpose Room, it lets you swim up and pass through into your base without taking on water. Every functional base needs at least one Hatch so you can get in and out. The Quartz component forms the reinforced viewport, while Titanium frames the pressure-rated seal.
How to Craft
Hatches are built with the Habitat Builder. Aim at a valid wall on a Corridor or Multipurpose Room and select the Hatch to mount it. You'll need Quartz from sandstone outcrops and Titanium from limestone.
