Mobile Vehicle Bay (Subnautica)

The Constructor is a tool that allows the player to construct submarines. It takes up nine inventory slots.

Uses
When released by the player, it will float to the surface and start to unfold itself. It can then be boarded by the player.

Its base houses four Constructor Bots that will activate themselves and start to float above the Constructor as soon as the player approaches. Using the display, the player can now construct the Seamoth or the Cyclops if they have the materials and blueprints at the ready.

Once the vehicle has been selected a blue beam and a submarine outline will appear in the air in front of the player, upon which the Constructor Bots will swarm out to assist in building the submarine of the player's choice using their own construction beams.
