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

The Pressure Reactive Armored 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 ground at a top speed of 14 Mph (23 kph), and a pair of boosters on the back of the vehicle provide vertical thrust. The PRAWN Suit also comes with its own beacon, similar to the Cyclops and the Seamoth.

Before the PRAWN Suit can be constructed, its fragments must be scanned. Five PRAWN Suit fragments can be found in the Aurora's vehicle bay, and 4 are needed to complete the blueprint. Three more suit fragments can be found in large wrecks in the Underwater Islands, Mountains, and Sea Treader's Path biomes (one in each wreck). While many smaller arm fragments can be found among various wrecks, there aren't enough of them outside of the Aurora to fully unlock the blueprint, which might confuse new players. This is why they cannot be scanned anymore.

A 3D model can be found on Sketchfab.

Overview

The PRAWN Suit can be used to explore places that are too deep for the Seamoth and too narrow for the Cyclops. It has a base crush depth of 900 meters and can be upgraded to withstand a maximum depth of 1,700 meters, making it one of the most useful deep-sea exploration vehicles (second only to the Cyclops). However, due to its limited mobility in the vertical dimension, it may be wise to use a Cyclops as a transport, as certain biomes such as the Blood Kelp Zone or Underwater Islands may be difficult for the PRAWN Suit to get out of on its own. However, the Grappling arm and Jetpack upgrade greatly enhances the Prawn Suit's mobility and somewhat mitigates this issue.

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 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.

Hazards

The PRAWN Suit has a health meter, and reaching zero will cause the vehicle to malfunction catastrophically and explode. Unlike the Seamoth, however, it is heavily armored and can endure most things that would otherwise severely damage or destroy a Seamoth, such as a Reaper Leviathan's grip. The Sea Dragon Leviathan is also capable of picking up the Prawn Suit.

Since it is not omnidirectionally propelled the PRAWN Suit is not damaged from environmental collisions and hence Hull Reinforcement upgrades are useless.

The Prawn Suit is susceptible to the Crabsquid's EMP attacks, which will temporarily disable all functions, including oxygen generation. Lava Larva can also latch onto it, which need to be removed from the outside.

When destroyed, any upgrades, power cells, and customizations will be lost; the resulting prawn suit pieces cannot be scanned or interacted with.

Features

The PRAWN Suit differs from other submersibles in the fact that it sinks in water and is piloted by walking along the seabed, and hence is comparably slower. It does have a jetpack which allows it to launch upwards, but its duration is sorely limited and takes some time to recharge.

There are 2 mechanical arms on the PRAWN Suit which are claw arms in their base form and can be upgraded for other options. All arms are activated independently of each other, and the base claw arm can be used either for striking, or for item collection. However, 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.

The PRAWN Suit requires energy from Power Cells to operate, which can be interacted with or switched out from the two sockets on either of the shoulder plates. It can be docked in a Cyclops vehicle bay or a Moonpool to recharge the onboard power cells. Unless the power supply is depleted, the player's Oxygen tank will be replenished upon entering, as is the case with the Seamoth and the Cyclops.

The PRAWN suit has a front-facing light that is always on. The light can be turned off only by removing the Power Cell in the left socket. Compared to the Seamoth this light is wider with less range.

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. If the Propulsion Cannon is used, items can be loaded from the storage space.

Ion Power Cells can also be used to power it.

Conclusion

The pinnacle of Alterra science, the PRAWN Suit serves as a much more protective and potentially offensive submersible compared to the other two. It is heavily armored and armed with 2 appendages, allowing self-defense and resource collection among many other possibilities. The PRAWN's small size compared to the cyclops optimizes it for traversing deep, narrow and dangerous places, and the many upgrades available can be used to make the Prawn suit a true one-for-all vehicle suited for any occasion.

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 (The depth module Mk. II is crafted at the Modification Station). 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.

Depth Module

Increases the vehicle's maximum crush depth, enabling it to survive greater pressure. Each successive module increases the crush depth by 400 meters. This effect does not stack.

Depth Module	Crush Depth
None	900 meters
MK1	1300 meters
MK2	1700 meters

Storage Module

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

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

Hull Reinforcement

Strengthens the chassis with a diamond lattice, increasing hull durability. Decreases collision damage by 50%; each successive module adds half the damage resistance of the last. Damage from aggressive fauna remains unchanged. Effect stacks with multiple modules. Useless for the Prawn Suit, as it does not take damage from collisions.

Modules	Damage Reduction
1	50%
2	75%
3	87.5%
4	93.75%

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 Use Reduction
1	15%
2	30%
3	45%
4	60%

Thermal Reactor

Replenishes the onboard power supply by harnessing 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 (95ºF)	10%
50ºC (122ºF)	18%
65ºC (149ºF)	26%
80ºC (176ºF)	34%
95ºC (203ºF)	42%
110ºC (230ºF)	50%

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, the LB button on Xbox One or the L1 button on PlayStation 4)

Claw Arm

Standard-issue environmental manipulation appendage. Useful for smashing small rocks for resources or delivering quick strikes to fend off predators. Items picked up are transferred to the onboard storage unit. Deals 50 damage per jab. Can be applied to both arms.
