Quick answer
Quick answer: how to unlock tadpole subnautica 2
To unlock the Tadpole, current public guides say to scan any three Tadpole fragments.
After that, build a Moonpool, attach a Vehicle Fabricator, gather the Tadpole materials, craft the vehicle, and test it near base before longer routes.
Step 1: confirm prerequisites
Before you chase fragments, make sure you can survive the route. Do not farm every material before you have the blueprint; get the scan progress first, then finish the build chain.
- Scanner.
- Comfortable oxygen plan.
- A path back to the Lifepod or base.
- Enough resources to prepare a Moonpool soon after scanning.
- A plan for charging and parking the vehicle.
Step 2: find and scan fragments
Current public guides say you need three scanned Tadpole fragments. If one route is too risky or does not match your build, use the backup areas listed in the fragment guide.
- South of the Lifepod, below overhanging wreckage.
- Southwest of the Lifepod, around 90m, inside the red-hatch bunker area.
- East-northeast of the Lifepod, near a current canyon arch.
Step 3: gather required materials
Current public guides report this Tadpole recipe. Needs fresh check: Early Access recipes can change. Confirm in your Fabricator before farming large stacks.
- 2x Titanium Ingot.
- 1x Glass.
- 1x System Chip.
- 1x Power Cell.
- System Chip: Quartz + Wiring Kit.
- Power Cell: 2x Basic Batteries + 1x Strong Acid + 1x Salt.
Step 4: craft or deploy the Tadpole
The Moonpool is reported to unlock after the second Tadpole fragment and cost 5x Titanium. Recheck if your build shows a different requirement.
- Build a Moonpool.
- Attach a Vehicle Fabricator.
- Choose the Tadpole from the vehicle craft menu.
- Test it close to base.
- Add a Tadpole Dock if you want a safer charging routine.
Troubleshooting: why the Tadpole is not unlocking
I scanned fragments, but the blueprint is missing
Make sure all scans completed. Partial scans do not count.
I have the blueprint, but cannot craft it
Check the Vehicle Fabricator path and your ingredient list. The Tadpole is not crafted from a normal hand tool menu.
I cannot build the Moonpool
Check whether your game has unlocked it and whether your base area has enough room.
My material list looks different
Mark it as a build change. Recipes may shift in Early Access, so follow your current in-game list first.
