I surfaced inside a cold, wrecked Alterra hull with the Repair Tool sparking at my fingertips. The door groaned and a corridor smelled of old power cells and rust—then I saw the Iso on the table. I knew that if you follow the right holes and doors, the Bioscanner blueprint will teach you far more than a single tool.
I’ve chased blueprints across every ruined ship in early access, and I’ll walk you through the exact route and the handful of items you need. You’ll save time, avoid the annoying backtrack, and pick up a Tadpole upgrade on the way. Read me, copy what I do, and you’ll have that scanner ready to scan lifeforms the ordinary Scanner misses.
Air tastes metallic in abandoned ships — Bioscanner blueprint location in Subnautica 2
Start at the fourth Angel Comb inside the Alien Ruins and swim upward. You’ll hit a crashed Alterra starship—use the screenshot below to match the wreck and find the entrance shown by Moyens I/O.
You must bring a Repair Tool because one of the key doorways is damaged and won’t open otherwise. Fix that door, push into the next room, then take the left-hand doorway. In the dining room you’ll see an Iso sitting on the table and a Tadpole upgrade nearby.
Search the corner of that room for a small hole leading through a chamber—follow it like a thread of air through ventilation until you reach the terminal with the Bioscanner. Use your Scanner to record the blueprint and the game will add the recipe to your tech list.
Where is the Bioscanner blueprint in Subnautica 2?
The short answer: the fourth Angel Comb in the Alien Ruins, up through a vertical route to the crashed Alterra ship. I’ve done this on Steam early access builds; other players on forums and guides (and screenshots from outlets like Moyens I/O) confirm the same coordinates and room layout.
Most workbenches look useless until you have the right tool — How to craft the Bioscanner in Subnautica 2
Once you’ve scanned the blueprint, head back to a Modification Station. The Bioscanner is a Scanner upgrade: it scans faster and reveals certain lifeforms that the base Scanner can’t.
How do I craft the Bioscanner?
You need a Modification Station and the resources listed in your tech menu—collect those components, bring them to the Station, and craft the Bioscanner. It replaces or upgrades your Scanner slot and gives you faster scans and access to extra Biomods when you catalogue alien life.
Do I need the Bioscanner to finish the game?
Short answer: yes, for the current early access campaign. The Bioscanner is required to scan the broken turbine before you can activate it and proceed toward the end sequence. Missing it means more backtracking and a stopped story path.
The Bioscanner is practical, but it’s also the ticket to new data—think of it as a flashlight in a fog that hides tiny, living secrets. It feels like pulling a loose thread on a heavily stitched seam.
If you want to speed-run this part, bring your Repair Tool, a spare Iso if you’re resource-poor, and a fully charged Tadpole; Steam community posts and Moyens I/O’s screenshots are good cross-references. Ready to push that damaged door and see what the Bioscanner reveals next?
