Prawn Suit

The ultimate deep-sea exoskeleton for mining, combat, and extreme depth survival.

The Prawn Suit is a heavy-duty exoskeleton vehicle designed for extreme depths on Planet 4546B. It serves as a mobile workstation and transport, allowing survivors to withstand crushing pressure and hostile encounters that would otherwise be fatal.

This robust machine bridges the gap between personal swimming gear and large-scale vessels like the Cyclops. It is widely considered an essential tool for late-game progression, enabling access to resource-rich zones deep beneath the ocean floor.

Lore & Background

In the harsh environment of 4546B, human technology had to adapt quickly to survive. The Prawn Suit represents a pinnacle of engineering resilience, combining the mobility of a diver with the durability needed to face predatory fauna like Reaper Leviathans. It was likely reverse-engineered or adapted from recovered alien tech to ensure humanity could reclaim resources necessary for escape.

While early exploration relies on swimming and small vehicles, the Prawn Suit marks the transition into true deep-sea colonization. Its ability to mine directly from rock walls reduces the need for constant base trips, making it a cornerstone of self-sufficiency in the abyssal zones where light rarely penetrates.

Its design philosophy prioritizes protection over speed. Unlike the sleek Seaglide or the massive Cyclops, the Prawn Suit is built to take hits and grind through obstacles, embodying the gritty determination required to survive on this hostile world.

In Their Own Story

The pressure gauge ticked past four thousand meters as I descended into the darkness. Outside the thick glass viewport, the ocean was a void of crushing blackness, broken only by the faint glow of my suit's floodlights. A shadow moved in the distance—too large to be a fish. I gripped the controls, feeling the hydraulic hum vibrate through the seat. The Prawn Suit groaned under the weight of the water column, but held firm. With a burst of thrusters, I drifted past the sleeping leviathan, safe within my metal shell, descending toward the thermal vents that promised salvation.

Reader's Guide

Crafting requires a Fabricator along with significant amounts of Titanium and Gold Ingots. Once built, it must be docked in a Prawn Suit Habitat Module for charging and storage. The suit features two upgradeable manipulator arms: the Drill Arm excavates resources like Silver, Lead, and Copper from rock walls, while the Manipulator Arm allows for precise object interaction.

A Seat Upgrade increases oxygen capacity significantly, extending deep dives. Strategically, it is essential for accessing the Deep Grand Reef and Lava Zones where standard vehicles cannot go. It also provides protection against aggressive fauna like Reaper Leviathans during transit. Additionally, the suit's durability allows it to take damage that would destroy a Seaglide or Cyclops hull in certain scenarios.

Players should manage battery consumption carefully when using the Drill Arm extensively. It acts as a mobile inventory extension for heavy resources. Mastery of this vehicle is often the turning point between surface survival and deep exploration. The Drill Arm is particularly useful for gathering resources without returning to base frequently. However, operating it drains power rapidly compared to simple movement.

The Manipulator Arm is vital for retrieving items from tight spaces or interacting with specific environmental triggers found in alien ruins. Without this suit, many late-game areas remain inaccessible due to pressure limits and predator density.
