Navigating the deepest trenches of Planet 4546B requires specialized equipment capable of withstanding extreme pressure. The Prawn Suit Depth Module Mk2 represents the ultimate operational upgrade for deep-sea exploration, unlocking access to late-game biomes like the Inactive Lava Zone and Lava Lakes. Securing this critical enhancement ensures your suit can dive down to maximum depths without taking crushing damage.

Understanding the Upgrade Requirements

Before crafting the Mk2 upgrade, players must first acquire and install the base Prawn Suit Depth Module Mk1. The Mk1 module provides a baseline crushing depth of 1,300 meters, which is essential for reaching the deep caverns where advanced resources reside. Upgrading to Mk2 pushes that limit to an impressive 1,700 meters, completely freeing players to explore the deepest aquatic ruins.

Required Crafting Materials

Fabricating the Mk2 module takes place at the Modification Station rather than a standard Fabricator. To complete the recipe, you will need your existing Depth Module Mk1, along with Kyanite, Kyanite crystals, and Titanium. Finding Kyanite requires visiting high-temperature zones, so bringing a Thermal Reactor Module for power management is highly recommended.

Locating the Necessary Blueprint Components

While the Mk1 depth module blueprint can be found in data boxes near wrecks or inside the Aurora, the Mk2 upgrade option is unlocked automatically at the Modification Station once you possess the base module. Navigating dangerous thermal vents and avoiding hostile leviathans are the main challenges when retrieving the necessary materials. Equipping a Grappling Arm and Drill Arm makes resource harvesting considerably safer during these deep expeditions.

Maximizing Deep-Sea Efficiency

Reaching a depth capacity of 1,700 meters opens up critical late-game narrative facilities and rare crafting ingredients. Combining the Mk2 depth module with adequate jump jet upgrades allows for seamless navigation through steep oceanic chasms. Preparing your Prawn Suit properly transforms dangerous deep dives into manageable resource gathering runs.
