Subnautica: Below Zero · Prawn Suit upgrade

Prawn Suit Depth Module MK1

This module increases the Prawn Suit’s crush depth to 700 m. Its blueprint unlocks when the Prawn Suit is unlocked, and it can be crafted at a Fabricator or Vehicle Upgrade Console.

How it works

Install the module in the Prawn Suit’s upgrade panel, located on the suit’s left side. The module does not stack. The MK1 module is also an ingredient in the MK2 depth module, which is crafted at a Modification Station.

When it helps

Use it when the suit needs the supported 700 m crush depth; retain it as a prerequisite if progressing to MK2.

Your next step

Unlock the Prawn Suit, then craft the module; the supplied evidence does not give its complete material quantities.
