Subnautica 2 Depth Module and MK2 Upgrades Guide

Depth Modules are progression gates. Before crafting MK2-style upgrades, check the next route, rare material needs, and whether your vehicle can survive the return trip.

Short answer: Depth Modules are progression gates. Before crafting MK2-style upgrades, check the next route, rare material needs, and whether your vehicle can survive the return trip.

Why Depth Modules Matter

Depth upgrades decide when a route becomes safe instead of stressful. If your vehicle is near its limit, the problem is not courage; it is progression timing.

Use depth modules to unlock repeatable routes, not one-way scouting trips.

MK2 Planning

Before crafting a MK2 upgrade, check the next route's resource requirements and the materials needed for later modules. Keep rare materials in reserve until you understand the chain.

Route Safety

A deeper maximum depth does not mean you should carry valuable cargo into an unknown biome. Scout, mark, return, then farm.

How To Use This Page

Use this page when progression feels blocked by depth, vehicle capability, a structure, or an upgrade chain. The goal is to identify the next safe unlock, not to rush the deepest route available.

Progression pages should be checked against current build behavior and official update notes.

Before You Act On This Guide

  • Identify the route or objective the upgrade unlocks.
  • Check every rare material in the upgrade chain.
  • Scout after installing an upgrade before farming.
  • Keep enough reserve material for the next module.

Pause if the upgrade requires rare materials but you cannot name the route it will unlock.
