Prawn Suit (Subnautica)

The Exosuit is an unimplemented vehicle.

As the name implies, it is a powered suit of armor, likely designed specifically for deep-sea operations, affording protection to a pilot while maintaining maximum dexterity with hydraulic limbs and a reinforced canopy. However, it is not directly worn, rather is a large frame that can be piloted in a seated position.

Using the Debug Console Commands, the Exosuit can be spawned into the player's world by entering the command "SPAWN EXOSUIT" or "ITEM EXOSUIT". However, It uses the older model that is just a placeholder (not the work in progress model)

According to a Twitter status, the player will be able to dock it into the Cyclops, in a fashion similar to the Seamoth, and will be able to use the Exosuit to explore dark and/or deep places.

A 3D model of the Exosuit can be found on Sketchfab.

Recipe
The Exosuit cannot be crafted at the moment, as it has not been fully implemented yet, but the recipe seems to be the following:

Speculation
An artwork published by the developers suggests that the Exosuit will be needed in order to safely cross the Inactive Lava Zone. Whether this is due to pressure - the Inactive Lava Zone is located at a depth of more than 1000 meters - or due to heat is unknown.

An concept art of the lost river biome is being shown that you have to use the Exosuit into that biome, some rumours say that the sea emperor will spawn in that biome whether this is possible for further of the storyline.

Early animations for the Exosuit can be viewed here.
