Subnautica 2 Crafting Guides
10 essential craftable items that will transform your underwater survival. Every fragment location, every material, every hidden shortcut — nothing missed.
Tadpole
Your first submarine. 200m depth, safe exploration, and the foundation for every other vehicle. Three fragments scattered across the map.
Scout Chassis
Fast recon vehicle for tight spaces. Agile, quick, and perfect for fragment hunting where the Tadpole can't fit.
Depth Module MK1
Upgrade Tadpole from 200m to 300m. Unlocks entirely new biomes, wrecks, and resources. The gate to the deep ocean.
Engine Efficiency Module
15% less power consumption. Stacks with solar charger for virtually unlimited range during daytime.
Photovoltaic Charger
Free solar recharging near the surface. The easiest vehicle upgrade — park and charge while you take a break.
Sonic Resonator
Detects hidden resources and fragments within 100m. Turns blind searching into targeted gathering.
Habitat Builder
Build underwater bases — your safe harbor, storage hub, and crafting center. Transforms you from survivor to settler.
High Capacity Air Tank
Double your oxygen to 90 seconds. The single most impactful early-game upgrade — reach deeper, stay longer.
Rebreather
Reduces depth-based oxygen drain. Combined with High Capacity Tank, makes 200m+ dives survivable.
Thermal Reactor Module
Infinite power from thermal vents. The endgame energy solution — park near lava, charge forever.
