You can find the grapple arm for the Prawn Suit in Subnautica by locating and scanning the fragments at wrecks in the Mushroom Forest and the Dunes biomes.
Exploring the Aurora
To find the grapple arm for the Prawn Suit in Subnautica, you will need to explore the Aurora spaceship wreckage. The Aurora is a large spaceship that has crash-landed on Planet 4546B and can be found in the shallows of the Aurora Rendezvous Point. The spacecraft is irradiated, so you will need a Radiation Suit or a reinforced diving suit to protect yourself from radiation exposure while exploring the wreckage.
Interior of the Aurora
Once inside the Aurora, you will need to navigate through the various corridors and compartments to find the Prawn Suit Fragment that contains the grapple arm blueprint. The Prawn Suit Fragment is typically found in the Cargo Bay area of the Aurora. You may encounter various obstacles and dangers inside the spaceship, so it is advisable to bring necessary supplies such as food, water, and a repair tool to fix any leaks or damaged equipment you may come across.
Searching for Clues
Exploring the Aurora thoroughly is crucial to finding the grapple arm blueprint for the Prawn Suit. Look for data terminals, PDA entries, and blueprints scattered throughout the wreckage, as they may contain valuable information or clues that will lead you to the location of the Prawn Suit Fragment. Pay close attention to any audio logs or text logs you find, as they may provide hints or directions to help you locate the grapple arm blueprint.
Scanning the Environment
Use your Scanner tool to scan the various objects, fragments, and data terminals inside the Aurora. Scanning is a vital tool in Subnautica as it allows you to collect data, unlock blueprints, and learn more about the game's lore and story. Be thorough in your scanning, as you may need to scan multiple fragments of the Prawn Suit blueprint to unlock the grapple arm blueprint specifically.
Building the Grapple Arm
Once you have collected all the necessary fragments and scanned the Prawn Suit blueprint, you can head back to your base or a nearby Fabricator to build the grapple arm attachment for your Prawn Suit. Crafting the grapple arm will require specific resources, which are typically metal salvages, copper ores, and other materials commonly found in the game world. Make sure you have enough resources on hand to create the grapple arm and enhance the capabilities of your Prawn Suit in Subnautica.
By following these steps and exploring the Aurora spaceship wreckage in Subnautica diligently, you will be able to find the grapple arm blueprint for the Prawn Suit and enhance your underwater exploration experience in the game.
