Read at own risk This article contains unmarked spoilers. Players new to the game would want to avoid or be cautious toward this article.

Vehicles are machines for exploration and transportation available to the player after acquiring their respective fragments and blueprints.

Vessels are crafted using the Mobile Vehicle Bay and can be piloted in certain environments and down to a certain depth.

Trivia

• The original vehicle plans for Subnautica saw the player have access to two small subs, two medium-sized subs, and one or two large subs. Concept art can be found for these other submarines. Ultimately, the Cyclops, prioritized for its "civilian" look, took up so much time that more subs that didn't truly add new gameplay were considered a bad investment of resources and were scrapped.
