It is normal when first piloting a Prawn suit to feel a sense of limitless power. Prawn operators receive weeks of training to counteract this phenomenon. You will have to make do with self-discipline. File:PrawnVO.ogg

― PDA, Dialogue

The Prawn Suit (Pressure Re-Active Waterproof Nanosuit Mk.III) is a vehicle. It is a powered suit of armor, designed for use in both the deep sea and in space - capable of affording protection to a pilot whilst maintaining maximum dexterity with hydraulic limbs and a reinforced canopy. It is not directly worn; rather, it is a large frame that can be piloted in a seated position.

The Prawn Suit has its own beacon, similar to the Cyclops and Seamoth. Unlike the other vehicles, however, the Prawn Suit walks along the ocean floor, using thrusters to move vertically.

Before the player can construct a Prawn Suit, they must first scan its fragments. Four large Prawn Suit fragments can be found in the Aurora's Prawn Bay, which each count for 25% of the blueprint. Many smaller Prawn Suit fragments can be found in various Wrecks, which each count for 5%.

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

Overview

The Prawn Suit can be used to explore dark and/or deep places. The Prawn Suit has a base crush depth of 900 meters and a fully upgraded crush depth of 1700 meters, making it the best deep exploration vehicle. However, due to its limited vertical mobility, it may be wise to use a Cyclops to transport the Suit, as certain biomes such as the Blood Kelp Zone or Underwater Islands may be difficult for it to get out of on its own.

Upon entering the Prawn Suit, the player's oxygen stores will be replenished - unless the Prawn Suit is depleted of energy, as is the case with the Seamoth and the Cyclops. In this case, 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 - reaching zero will cause the Prawn Suit to malfunction catastrophically and explode. Unlike the Seamoth however, the Prawn Suit is heavily armored and can endure most things that would otherwise severely damage or destroy a Seamoth, such as a Reaper Leviathan's grip.

Alternatively, the Prawn Suit can be used on land for exploration of dangerous areas. (Keep in mind that the Prawn Suit is not as mobile on land. The thrusters are nearly useless, even if the Prawn Suit Jump Jet Upgrade is equipped.) As the suit is immune to heat and poison (though not direct contact with lava), the Prawn Suit is also great for collecting resources in hazardous areas such as near Lava Geysers, or collecting Gas Pods, or for simple protection against most low-to-mid tier predators.

The Prawn Suit requires energy from two Power Cells to operate. The Prawn Suit can be docked at a Cyclops or a Moonpool to recharge.

The Prawn Suit comes equipped with a 6x4 inventory space, accessed from outside in the rear. Any items picked up with the claw arm or drilled with the drill arm are automatically placed in the 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.

How to Use

Enter the Prawn Suit with LMB.
Pilot the Prawn Suit using the same controls as walking on dry land or in a Seabase.
Exit the Prawn Suit with E. The Prawn Suit will assume a "sitting" position when not in use, allowing the player to access its Power Cells, storage compartment and upgrade panel.
LMB and RMB to use the arms. LMB for the left arm, and RMB for the right arm.
SPACE to jump, hold for the thrusters. Using the thrusters will deplete their internal energy, which recharges by itself when not in use.

Upgrades and Customization

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. Opening the panel reveals six slots - four for vehicle upgrades and two for arm attachments. The storage, hull reinforcement and engine efficiency modules are compatible with the Seamoth.

Prawn Suit Depth Module

Increases the vehicle's maximum crush depth by 400 meters, enabling it to survive greater pressure. It does not stack, unlike other upgrades.

Depth Module	Crush Depth
None	900 meters
Mk I	1300 meters
Mk II	1700 meters

Storage Module

Increases maximum onboard storage capacity by six slots. Effect stacks with multiple modules.

Modules	Slots
0	24
1	30
2	36
3	42
4	48

Hull Reinforcement

Strengthens chassis with a diamond lattice, permanently increasing hull durability. Decreases incoming damage by 20% and completely eliminates damage from ambient environmental hazards. Effect stacks with multiple modules.

Modules	Damage Reduction
1	20%
2	40%
3	60%
4	80%

Engine Efficiency Module

Increases maximum battery life by recycling engine thermal waste and decreases total power consumption by 15%. Effect stacks with multiple modules.

Modules	Power Consumption
1	-15%
2	-30%
3	-45%
4	-60%

Prawn Suit Thermal Reactor

Replenishes the onboard power supply by harnessing the thermal energy in areas with an ambient temperature of 35ºC or greater. The charge rate depends on the amount of heat in the surrounding environment.

Temperature	Charge Rate
35ºC	10%
50ºC	18%
75ºC	26%
90ºC	34%
105ºC	42%
120ºC	50%

Prawn Suit Jump Jet Upgrade

Greatly increases thruster power and provides greater acceleration and maneuverability. Useful for reaching high ledges when used in conjunction with the grappling arm; burst-fire greatly increases lateral jump range.

(Activate by pressing and holding the spacebar on PC and Mac or the A button on the Xbox One)

Prawn Suit Claw Arm

Standard-issue manipulator arm. Useful for smashing rocks for resources or delivering quick strikes to fend off predators. Items picked up are transferred to the onboard storage unit. Can be applied to either or both arms.
