Description
The PRAWN Suit is the game's premier exosuit, a bipedal mech that trades the Seamoth's speed for raw power and seafloor mobility. Instead of swimming, it walks across the seabed and uses a jetpack boost for vertical traversal. Its defining feature is a pair of swappable arm modules, including the Drill Arm for mining large resource deposits and the Grappling Arm for scaling walls and pulling yourself across chasms. Deploy it for late-game resource runs and leviathan-class encounters.
How to Craft
Craft the PRAWN Suit at a Vehicle Bay after scanning fragments found in deeper wreck sites. Stockpile Titanium Ingot ahead of time, as this recipe demands twice the ingots of the Seamoth.

Crafting Station

Mid-game unlockWhat it Does
The PRAWN Suit walks the seafloor, drills large resource deposits, and grapples across vertical terrain. It is the only vehicle that can mine Large Resource Deposits and scale deep cave walls.
Seafloor Walking
Walks along the seabed for stable, precise positioning while mining and exploring trenches that submarines cannot reach.
Drill Arm
Mines Large Resource Deposits of Lithium, Diamond, Kyanite, and other rare materials that hand tools cannot break.
Grappling Hook
Fires a grappling arm to pull yourself across chasms, scale walls, and reposition quickly in tight cave systems.
Upgrades
The PRAWN Suit supports two primary upgrade paths: arm modules for utility and depth/jetpack modules for mobility. Mix and match based on whether you prioritize mining throughput or deep exploration.

How do I unlock the PRAWN Suit?
Scan PRAWN Suit fragments in wreck sites and deeper biomes, then craft at the Vehicle Bay. Fragments are commonly found in the Underwater Islands, Lost River, and around large wrecks. You'll need several scans to complete the blueprint.
Can the PRAWN Suit swim?
No, it walks on the seafloor and uses a jetpack boost for vertical movement and grappling. The jetpack provides powerful upward thrust but drains energy quickly, so plan your ascents and use the Grappling Arm for sustained mobility.
What arms can the PRAWN Suit equip?
Drill Arm, Grappling Arm, Propulsion Cannon Arm, and Torpedo Arm are all available. You can mix and match arms on the left and right slots, letting you run a Drill plus Grapple combo for mining, or dual utility setups for specific missions.
