Quick answer
Unlock the Tadpole by scanning Tadpole fragments, then build it through the vehicle crafting chain. GameSpot reports that the blueprint requires at least three Tadpole Fragment scans, while PC Gamer emphasizes Power Cell prep, Strong Acid, spare power, and Repair Tool safety before longer trips.
Field notes before the first Tadpole trip
The vehicle is not a license to get lost
The first Tadpole makes the map feel smaller, which is exactly when players start overreaching. Run one known route first before using it for a deep scouting trip.
Power Cell planning comes before range
A vehicle with weak power planning turns into a stranded landmark. Sort the Basic Battery, Strong Acid, and Salt chain before treating the Tadpole as your new home.
Park it where the return is obvious
A bad parking spot wastes the time the vehicle was supposed to save. Use a Beacon, a clean Moonpool route, or a clear terrain cue before leaving it behind.
Tadpole unlock and first-route plan
Scan Tadpole fragments first
GameSpot reports that at least three Tadpole Fragment scans unlock the blueprint. Treat each fragment trip as a scan-first route instead of filling your inventory and forgetting the reason you came.
Prepare the vehicle build chain
Do not start the final build with materials scattered across five lockers. Stage the Vehicle Fabricator route, Moonpool support, and the main vehicle materials before the last haul.
Craft power before the hull
PC Gamer links Tadpole progress to Power Cell production, and Power Cell pushes you back into Basic Battery, Strong Acid, and Salt. Solve that chain before expecting the vehicle to carry exploration.
Bring repair safety
A Tadpole is most valuable when it survives repeated routes. Unlock or stage the Repair Tool plan before using the vehicle as a long-range scout in rough water.
Make the first drive boring
The first trip should teach you handling, parking, power drain, and return timing. Save the brave deep route for the second or third run, once the vehicle feels predictable.

Tadpole progression checklist
| Milestone | Why it matters |
|---|---|
| Fragment scans | Unlocks the Tadpole blueprint. |
| Vehicle build chain | Requires base and fabrication support before the vehicle exists. |
| Power Cell prep | Vehicle progress depends on the power chain. |
| Repair planning | Keeps long-range routes from becoming one-way trips. |
| Upgrade planning | Depth and utility modules decide when deeper routes become practical. |
Build support before range
A vehicle lets you reach danger faster. Bring repair options, power planning, and a clear return route before treating the Tadpole as permission to dive everywhere.
FAQ
How do you unlock the Tadpole in Subnautica 2?
Scan Tadpole fragments until the blueprint unlocks, then build it through the vehicle crafting chain. GameSpot currently reports at least three Tadpole Fragment scans for the unlock.
What should you prepare before using the Tadpole?
Prepare Power Cell materials, repair safety, and a clear return route before using the Tadpole for deeper exploration. PC Gamer specifically calls out spare power and Repair Tool planning as useful support.
Why does Power Cell matter for Tadpole?
Current Tadpole route reporting connects the vehicle craft to Power Cell. That means Basic Battery, Strong Acid, and Salt planning can block the vehicle even after fragments are done.
Should I rush deep routes after building Tadpole?
No. Run a known route first, learn the parking and power rhythm, then push deeper once the vehicle has support from Repair Tool, Moonpool, and upgrades.
