Subnautica Below Zero Prawn Suit Location and Upgrade Guide

Navigating the frozen depths of Planet 4546B in Subnautica Below Zero requires robust equipment capable of withstanding extreme pressure and dangerous predators. The Pressure Reactive Waterproof Nano Suit, famously known as the Prawn Suit, serves as the ultimate mechanical exoskeleton for deep-sea exploration and resource gathering. Acquiring this heavy vehicle is a critical turning point that allows divers to transition from vulnerable prey to a well-protected underwater explorer.

Finding the Prawn Suit Blueprints

To unlock the manufacturing specifications for this mechanical suit, players must locate and scan four distinct structural fragments hidden across the ocean floor. The most reliable site to gather these blueprints is the Koppa Mining Site, which is situated deep within the Thermal Spires biome. Navigating this industrial complex requires caution due to narrow tunnels and limited oxygen levels, making a reliable vehicle like the Seatruck highly recommended for temporary air refills.

Alternatively, players exploring the abandoned Outpost Zero or scattered wreckage in the deep ocean may encounter additional wreckage pieces. Scanning these broken components systematically pieces together the complete schematic inside your database. Once all four scans are complete, you can manufacture the primary chassis using the Mobile Vehicle Bay with high-tier materials like titanium ingots and computer chips.

Essential Exploration Upgrades

A stock mechanical suit offers great armor protection, but it requires specialized modules to maximize its efficiency in deep-sea trenches. The Depth Module stands out as the most crucial enhancement, allowing the vehicle to descent to extreme depths without suffering structural damage from intense water pressure. Combining this with the Jump Jet Upgrade significantly increases vertical mobility, allowing players to escape steep underwater canyons and deep geothermal ravines.

Thermal Reactor modules provide a continuous source of energy whenever the vehicle rests near underwater volcanic vents or thermal spires. This passive charging mechanism eliminates the need to constantly swap out heavy power cells during extended expeditions. Equipping these core survival systems transforms your mechanical walker into a self-sustaining mobile fortress for deep trench mapping.

Maximizing Utility With Arm Attachments

The true power of the Prawn Suit lies in its interchangeable mechanical limbs, which replace the standard claw arms to perform unique tactical tasks. The Drill Arm is an indispensable attachment designed to break down large resource deposits that cannot be harvested by hand. This tool makes gathering large quantities of diamond, magnetite, and kyanite far more efficient during end-game resource collection.

For high-speed movement and combat evasion, combining the drilling apparatus with a Grapple Arm creates unmatched mobility. This utility wire allows pilots to hook onto rock faces, pull themselves forward rapidly, or even hitch a ride on massive leviathans. Mastering the dual-arm setup enables you to clear difficult terrain quickly while gathering the rare minerals necessary for late-game story progression.
