The Mobile Vehicle Bay is a Deployable item that allows the player to construct vehicles. It takes up nine inventory slots, and can be crafted by using the Fabricator. However, the player must first scan three Fragments for the Mobile Vehicle Bay.

To put the Mobile Vehicle Bay back in your inventory, look down at the metal platform.

Uses Edit

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 Printer Pods that will activate themselves and start to float above the Mobile Vehicle Bay as soon as the player approaches. Using the display, the player can now construct the Seamoth, the Cyclops, the Prawn Suit, or the Rocket Launch Platform if they have the materials and blueprints at the ready.  

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