The Exosuit facilitates mobility in high-pressure and zero-gravity environments, turning the wearer into a bipedal mechanical rock puncher — rock grub ingestion not required.

― PDA.

The Pressure Re-Active Waterproof Nano Suit Mk.III (abbv. Prawn Suit Mk.III) is a bipedal mechanical walker, designed for use in extreme-pressure and zero-gravity environments. A plasteel-reinforced canopy of enameled glass protects the single occupant, and dexterity is provided by hydraulic limbs that are capable of striking with enough force to crush bone and pulverize rock. When not in use outside of water, the vehicle assumes a seated position.

Lateral movement is provided by mechanical legs that propel the vehicle along the seabed at a top speed of 24 kph (14 mph), and a pair of boosters on the back of the vehicle provide vertical thrust.

A 3D model can be found on Sketchfab.

Overview

The Prawn Suit can be used to explore deep areas. It has a base crush depth of 400 meters.

Unless the power supply is depleted, the player's Oxygen tank will be replenished upon entering. If power is depleted, the oxygen will run out slowly until the point where the player is losing oxygen within the Prawn Suit itself.

The Prawn Suit has a health meter, and reaching zero will cause the vehicle to malfunction catastrophically and explode.

The Prawn Suit requires energy from two Power Cells to operate. It can be docked onto the Seatruck Docking Module or in the Moonpool to recharge.

The vehicle comes equipped with a 24-slot inventory space, accessed from outside in the rear. Any items picked up with the default Claw Arm or drilled with the Drill Arm are automatically placed in the Prawn Suit's inventory if there is room. Bear in mind though that there is a slight delay between clicking and activating the respective Claw Arm on the suit, so a player may accidentally punch a creature they are trying to collect or miss a falling item.

• Exiting the vehicle when out of water will cause it to assume a sitting position, allowing access to its Power Cell slots, storage compartment and upgrade panel more easily.
• Using the thrusters will deplete their internal energy, which recharges by itself when not in use. Staying on a solid surface will increase the rate at which the thrusters recharge.

Recipe

The blueprint for this item is unlocked by scanning fragments in the Koppa Mining Site, in the Bow section of the Mercury II, at Outpost Zero, and the Phi Excavation Site. It is crafted in the Mobile Vehicle Bay. (no target detected)

Modules

The Prawn Suit can be customized with the Vehicle Upgrade Console, which the player can use to craft upgrades and change the vehicle's name and color scheme. Upgrades can be installed and swapped via a panel on its left shoulder. The Prawn must be detached from the Moonpool in order to access this panel. Opening the panel reveals six slots - four for vehicle upgrades and two for arm attachments.

Trivia

• In earlier builds, the Prawn Suit had an ability called "Powerslide", basically a precursor of the Prawn Suits Speed Boost Ability.
• The Prawn Suit is the only vehicle from Subnautica to return in Below Zero.
• In Subnautica the crush depth for the Prawn Suit was 900m instead of the 400m in Below Zero
