This list is ordered to provide a seamless progression, and ensures that you’re getting the best experience from your modding ventures.

Map:

• Creator: newman55
• Key Feature: A dynamic, interactive map that reveals the environment.
• Why it’s essential: While the thrill of exploration is central to Subnautica, a map can be a game-changer. This mod provides a comprehensive overview of the game world, revealing biomes, points of interest, and your current location. However, the map doesn’t entirely remove the need for exploration. The fog of war means you have to traverse the world to unveil its secrets, preserving that initial wonder. This mod is useful for finding the blueprints for crafting.

All Items 1x1:

• Creator: MrPurple6411 and Cookay
• Key Feature: Makes all items occupy a single inventory slot.
• Why it’s essential: Inventory management can quickly become a frustrating aspect of Subnautica. This mod eliminates the headache, ensuring that every item, regardless of size, occupies only one inventory slot. This is a game-changer for keeping your inventory clean. It’s a small change that dramatically impacts your ability to gather resources and explore without constantly returning to base.

EasyCraft:

• Creator: newman55
• Key Feature: Automates the crafting process, including grabbing items from storage.

MoreQuickSlots:

• Creator: RandyKnapp
• Key Feature: Increases the number of quick slots available for tools and items.

Cyclops Docking Mod:

• Creator: OSubMarin
• Key Feature: Allows you to dock the Cyclops at your base.
• Why it’s essential: The Cyclops is a cornerstone of late-game exploration. Its sheer size, however, makes docking in your base impossible.
