Map-ready notes
Location index with confidence labels
Source-backed fragment, craft, and material notes. Full copied POI databases are intentionally excluded.
Closest fragment 1: south wreck cliff
Related task: Scan 3 Tadpole fragments
From the Lifepod, swim roughly south for about 115m. Look for a large wreck piece hanging off a cliff; the fragment is reported at the bottom below the overhang.

Closest fragment 2: southwest Colonist Bunker
Related task: Scan 3 Tadpole fragments
Head about 250m southwest from the Lifepod to roughly 90m depth. Find the red hatch into the Colonist Bunker / Unauthorized NoA Modification area; the fragment is reported on a wall rack inside.
Risk: Bring enough oxygen for a 90m dive and mark your exit.

Closest fragment 3: east-northeast current canyon
Related task: Scan 3 Tadpole fragments
Swim about 250m east-northeast from the Lifepod. Look for a strong current dipping into a canyon and an arch above it; the fragment is reported near a small wreck platform on the seabed.

Backup fragments: Great Jaw, Old Habitat, Cicada Wreck, Zezuran Desert, Tadpole Pens
Related task: If the closest route is blocked
Beebom lists more known fragments, including Great Jaw Cliffside, behind Old Habitat, past purple jellyfish, near the Alterra wreck plateau, inside Cicada Wreck, Zezuran Desert, and Tadpole Pens. Use these as backup search areas rather than copied coordinate pins.
Risk: This site avoids republishing full POI databases; verify in your save and send corrections if a fragment moved.

Moonpool + Vehicle Fabricator chain
Related task: Craft the Tadpole
After fragment scanning, construct a Moonpool, attach a Vehicle Fabricator, then craft the Tadpole from the Vehicles menu. Keep room around the Moonpool for launch and docking.

Material priority list
Related task: Gather Tadpole materials
Prepare Titanium Ingots, Copper Ingot, Glass, System Chip, and Power Cell inputs. RPS notes System Chip uses Quartz + Wiring Kit, and Power Cell uses Basic Batteries, Strong Acid, and Salt.

Upgrade planning
Priority Tadpole upgrades to check after launch
These notes focus on what each module does and where current public guides say to look. Recheck recipes before farming because Early Access patches can change values.
Scout Ray Chassis
Improves Tadpole speed and mobility according to current public guides.
Where to look: Beebom reports its blueprint inside Tadpole Pens; RPS describes it as a later chassis upgrade.
Source: Beebom + RPS upgrade notes.
Engine Efficiency Module
Reduces power consumption; Beebom reports a 20% reduction and notes modules can stack.
Where to look: Reported inside the Alien Base.
Reported materials: Beebom lists 1x Titanium Ingot, 2x Glass, 1x System Chip.
Source: Beebom upgrade section.
Depth Module
Supports deeper exploration beyond the default Tadpole pressure limit; RPS warns the base Tadpole can only withstand pressure up to 250m.
Where to look: Unlock path may require later Modification Station progress; verify in your current build.
Source: RPS upgrade overview; exact recipe not republished here until rechecked.
Photovoltaic Charger
Restores vehicle energy slowly in shallow daylight areas.
Where to look: Beebom reports it inside the Cicada Wreck EVA Prep section after receiving the blackbox recording signal.
Reported materials: Beebom lists 1x Copper Ingot, 1x Strong Acid, 1x Troilite.
Source: Beebom upgrade section.
Cavitation Muffler
Reduces vehicle noise and may lower hostile creature detection risk.
Where to look: Beebom reports it near the Metal Farms biome southeast of the Alien Base and warns about map-edge threat risk.
Reported materials: Beebom lists 3x Titanium and 2x Strontium.
Source: Beebom upgrade section.

Before you trust a guide fact
How many Tadpole fragments do I need?
Current public guides say you need to scan any three Tadpole fragments to unlock the Tadpole blueprint.
What is the fastest fragment route?
RPS reports three close Lifepod-area fragments: south below an overhanging wreck cliff, southwest in the Colonist Bunker red hatch around 90m, and east-northeast near a current canyon arch.
What do I build before the Tadpole?
Build a Moonpool, attach a Vehicle Fabricator, and optionally add a Tadpole Dock so a powered base can recharge the vehicle while docked.
What materials does the Tadpole need?
Reported recipe: 2x Titanium Ingot, 1x Glass, 1x System Chip, and 1x Power Cell. Check your current Early Access build before farming large stacks.
Is this made by the Subnautica 2 team?
No. This is a fan-made guide utility and is not affiliated with or endorsed by Unknown Worlds, Krafton, or the Subnautica 2 team.
Will the guide show spoilers?
Spoiler-sensitive Tadpole Pens content stays folded by default and only appears after you choose to reveal it.
Do I need to sign up to save my checklist?
No. Checklist progress is saved locally in your browser with localStorage and does not require an account.
Where should I start if I only need the controls?
Start with the Tadpole Controls guide. It covers basic driving, docking, power checks, and common control problems without forcing you through the full unlock walkthrough.
What if I only need fragments?
Use the Tadpole Fragments guide. It focuses on the three-fragment unlock path, source-backed route notes, and backup search areas.
Will the Pens guide spoil the code?
No. The Tadpole Pens guide keeps direct puzzle help behind a spoiler reveal, and the page does not show a fixed code unless it has been freshly verified.
