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, the Exosuit can be spawned into the player's world by entering the command "SPAWN EXOSUIT" or "ITEM EXOSUIT". However, It now uses the new Work In Progress model (which does not work at all). The model used before the Work In Progress model was the model used in the Pre-Alpha version of the game.

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.

Early animations for the Exosuit can be viewed here.

In the deep Grand Reef, a lot of unknown diamonds are buried inside the ground mass. The Exosuit will be able to access these with its equpment in the near future.

Pre-Alpha
In the Pre-Alpha game, the Exosuit was implemented but buggy. It also had jet boosting capabilities but no mining drill, as seen in the Sketchfab Model shown below.
