Computer Chip
Computer Chip is an advanced logic component in Subnautica 2, crafted from Gold, Copper Wire, and Stalker Teeth. It is the keystone of the tech tree: the Habitat Builder, Scanner Room, vehicles, and almost every piece of late-game technology chain through Computer Chips.
Quick Info
How to Craft & Source Materials
Computer Chips are crafted at the Fabricator from 2 Gold, 1 Copper Wire, and 1 Stalker Tooth. Gold and Copper are farmed from outcrops, but the Stalker Tooth is the bottleneck — it only drops when Stalkers play with scrap metal in the Kelp Forest. Plan to dedicate a session to baiting Stalkers before banking large numbers of Computer Chips.
Gold (x2)
Mined from sandstone outcrops in the Kelp Forest and Grassy Plateaus.
Easy to stockpileCopper Wire (x1)
Crafted from 2 Copper Ore mined from limestone outcrops in shallow biomes.
Cheap intermediateStalker Tooth (x1)
Drops when Stalkers play with scrap metal in the Kelp Forest.
Bottleneck materialUses & Recipes
Computer Chips unlock the entire mid- and late-game tech tree. The Habitat Builder lets you construct bases, the Scanner Room dramatically speeds up resource farming, and most vehicles chain through at least one Computer Chip. Plan to bank 6–10 Computer Chips to cover the core progression.
Tips & Strategies
Bait Stalkers with Scrap
Drop Titanium or metal scrap near a Stalker in the Kelp Forest. When it picks the scrap up to play, it has a chance to drop a tooth. Carry 5–10 scrap pieces and rotate between Stalkers for the best yield.
Use a Scanner Room
Once you have your first Computer Chip, build a Scanner Room in the Kelp Forest and set it to scan Stalker Teeth. It highlights loose teeth on the seafloor so you can collect them without baiting each Stalker individually.
Pre-Craft a Stack
Computer Chips only stack to 5 and are needed by almost every advanced blueprint. Once your Stalker Tooth supply is steady, craft 5–10 in advance so you can build vehicles and base modules without interrupting exploration.
Watch for Stalker Aggro
Stalkers can damage you while you're baiting them. Wear a Survival Knife for defense and stay close to your Seamoth so you can retreat if multiple Stalkers swarm at once.

Gold and Copper are farmed from outcrops in shallow biomes, but the Stalker Tooth is the limiting factor — it requires Stalkers in the Kelp Forest. Pin Stalker Tooth farming spots on the interactive map for repeatable Computer Chip production.

How do I craft a Computer Chip?
A Computer Chip is crafted at the Fabricator from 2 Gold, 1 Copper Wire, and 1 Stalker Tooth. Gold and Copper come from outcrop farming, while the Stalker Tooth is the bottleneck — it only drops when Stalkers play with scrap metal in the Kelp Forest.
Where do I get Stalker Teeth?
Stalker Teeth drop when Stalkers play with scrap metal. Drop Titanium or metal scrap near a Stalker in the Kelp Forest and it will pick it up to play, with a chance of leaving a tooth behind. Carry 5–10 scrap pieces for the best yield per session.
What is the Computer Chip used for?
The Computer Chip unlocks the Habitat Builder, Scanner Room, Seamoth, Cyclops, and most advanced electronics. It is the keystone of the tech tree, so plan to bank 6–10 of them to cover core mid-game progression.
Can I avoid using Stalker Teeth?
No — Stalker Teeth are a required component for every Computer Chip. The good news is that they are renewable as long as you keep baiting Stalkers with scrap metal. Build a Scanner Room in the Kelp Forest and set it to scan Stalker Teeth to automate discovery of loose teeth on the seafloor.
