The Hatch, also known as the "Super Barrique Selective Passage Portal", is a base module constructed with the Habitat Builder to provide an entrance and exit to a seabase.

Recipe
The recipe is unlocked by default once the Habitat Builder is unlocked.
| Ingredient | Amount |
|---|---|
| Titanium | 1 |
| Quartz | 1 |
Crafted using: Habitat Builder
Appearance
The Hatch is a circular portal enclosed by a white, solid ring. On the outside, a yellow rail surrounds the outermost edge while a smaller, yellow two-thirds rail follows the interior edge near the portal opening. The inner rail leaves a gap at the bottom.
Purpose
The Hatch provides an entrance and exit point to a Seabase.
- It can be placed on the sides of Rooms and Corridors, as well as the end of a Corridor.
- It cannot be placed on the top or bottom of Rooms or Corridors.
- In Multiplayer, several Players can use the Hatch at the same time.
Databank Entry
Source: Fabricate a Habitat Builder
The "Super Barrique" selective passage portal allows for simultaneous two-way, multiple-crew traffic between a pressurized interior and a dangerous exterior. This eliminates the need for lengthy mechanical cycles which can interrupt traffic and reduce the joy of free motion.
- Heavy duty nanomembrane: molecular machines clasp hands across the entire surface of the hatch
- Sapphire laser systems provide energy and programming
- Membrane accepts crew members and cargo, while rejecting pressure and intruders
- Filters loose biomatter: great for Kharaa monitoring
The membrane is only slightly weaker than solid titanium. In the event of a power loss, the nanomachines can sustain their grip for days. A mechanical iris is optionally provided to seal in the event of a long-term power failure.
Instances of limb amputation or removal due to membrane error have been entirely eliminated from the design.
Trivia
- The decision to redesign the hatch to include a bidirectionally permeable nano-membrane, as opposed to the mechanical hatches of previous games, was made to better account for multiplayer.
