Video watch notes
What to pause, compare, and write down
Do not watch the video like entertainment only. Use these notes as a second-screen checklist: pause on landmarks, confirm the player action, then return to the written route.
Watchlist
Pause on Module list and identify the landmark, depth band, or objective state before following the next step.
Use Depth gate to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Route test as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.

Module list
Treat Tadpole modules as route changes rather than collectible checkmarks.
Action: Choose the module that solves the next route blocker.

Depth gate
Depth gates should be solved before optional comfort modules.
Action: Scan fragments and check module progress.

Route test
Test every upgrade on a known route before deep exploration.
Action: Install the module before the next deep push.

Use this section like a second-screen route sheet. Open each checkpoint, compare the frame, do the action, then stop if your route no longer matches the video evidence. It keeps the guide useful even when Early Access shifts small placements or creature behavior.

Route decision lab
Decide if this route is worth running now
This section turns the video into a practical in-game decision. Use it before leaving base, after the first landmark, and again before entering a deeper or darker area.
Route purpose
Unlock Tadpole modules by route need: depth for deeper objectives, cargo for repeated hauls, armor for threat routes, and mobility when travel time blocks progress.
Visual checkpoint
Treat Tadpole modules as route changes rather than collectible checkmarks.
Map anchor
All Tadpole Modules Anchor in Vehicle module route cluster. Use it for use this when the tadpole needs an upgrade plan instead of random fragment chasing.
Abort rule
Unlocking modules by curiosity instead of route value.
Field manual translation
Unlock Tadpole modules by route need: depth for deeper objectives, cargo for repeated hauls, armor for threat routes, and mobility when travel time blocks progress. Use this completion route manual as a second-screen checklist: identify the entry condition, confirm the objective with a visual proof point, then stop when the return rule is met. This keeps the article practical for Early Access patches without pretending every coordinate or state is final.
Primary job
Tadpole - Choose the module that solves the next route blocker.
Best entry habit
Tadpole unlock - Scan fragments and check module progress.
Stop condition
Unlocking modules by curiosity instead of route value. - Install the module before the next deep push.
Patch-safe reading
Exact item positions can shift during Early Access. The useful part of this page is the route logic: what to prepare, what visual cue to confirm, what objective to finish, and when to turn back.

What this guide covers
Requirements
- Tadpole unlock
- Module route
- Test loop
Use this if
You want a route you can follow from video evidence without needing exact official coordinates. The screenshots and steps are written to help you recognize areas, landmarks, and decisions while playing.
Early Access can move details. Treat this as a video-based walkthrough and verify landmarks in your own build.
Step-by-step walkthrough
Follow the video route without guessing
Choose the module that solves the next route blocker.
Use this step as a route checkpoint, not as a promise that every object spawns in one exact coordinate. Match the landmark, compare the screenshot, then continue only if the return path is still clear.
If your game build looks different, stay with the same decision: keep oxygen safe, scan or collect the current blocker, and return before pushing into the next unknown area.

Detailed notes
Tadpole module checklist route plan
All Tadpole Modules Guide is useful when the route is treated as a focused job instead of a full-map sweep. Start by naming the blocker, checking the loadout, and matching the first landmark before copying the video. The player goal is not to memorize every second of movement; it is to understand why the route begins there, what proves progress, and when the route should stop.
Route type: Tadpole module checklist
Proof to confirm: module unlock, install, and controlled test
Primary blocker: Tadpole unlock
Best follow-up: Test on known terrain before using it in danger.
How to use this in-game
Turn this note into one action before leaving base: decide the objective, keep only the materials or tools that support it, then stop the route once the scan, pickup, or landmark is confirmed. This keeps the guide useful even when Early Access patches move small details.
How to use the video evidence
Watch for the entry frame, the proof frame, and the exit frame. The entry frame tells you whether you are in the right terrain band. The proof frame tells you whether the scan, pickup, blueprint, puzzle state, or build decision actually happened. The exit frame protects the run from turning into a panic search after the objective is already solved.
Entry frame: match terrain before diving deeper
Proof frame: confirm module unlock, install, and controlled test
Exit frame: return before adding side goals

Stop rule
Stop after each module is tested on a route where its value is obvious. If the route fails, change one variable before trying again: bring the missing tool, empty inventory, approach from a clearer landmark, or wait until oxygen, vehicle depth, or defensive options match the route. That makes the next attempt safer and gives the page useful field notes instead of repeated guesswork.

Video route notes
All Tadpole Modules Guide should be followed as a completion route, not as a memory test. Start by watching the first route movement and naming the entry condition before copying the path in-game. Choose the module that solves the next route blocker. Then pause again when the video reaches the first visible proof point, because that is where the guide changes from general advice into an action you can repeat. Scan fragments and check module progress. If the route starts to feel different in your build, keep the same player goal: finish the unlock cleanly and know whether a return trip is needed.
Entry check: Tadpole unlock
Route action: Choose the module that solves the next route blocker.
Proof to look for: scan or pickup proof

Screenshot checkpoints
Use screenshots as checkpoints instead of decoration. The first image should answer where the route begins, the second should show what confirms progress, and the third should explain what to do after the scan, pickup, puzzle state, or threat read is visible. Install the module before the next deep push. This is especially important in Early Access because exact positions can drift while landmarks, depth bands, room states, and player decisions stay useful. A good screenshot lets you say, "I am at the right kind of place," before you risk oxygen, storage space, or vehicle safety.
Entry frame: match the landmark before moving deeper
Proof frame: confirm scan or pickup proof
Exit frame: know the return direction before adding side goals

Stop rule and next dive
The most useful part of this page is the stop rule. Unlocking modules by curiosity instead of route value. Testing new modules first in threat-heavy areas. When the objective is confirmed, return and convert it into progress: craft the upgrade, sort the material, save the route note, or mark the blocker as solved. If the route fails, do not repeat the same swim blindly. Change one variable at a time: enter from a clearer landmark, reduce inventory clutter, bring the missing tool, or wait until oxygen and vehicle support match the route. That turns a failed completion route into better field knowledge instead of another untracked cleanup sweep.

Testing new modules first in threat-heavy areas.
Using extra cargo or armor as an excuse to overextend.
FAQ
Is this guide for the current Subnautica 2 build?
This page is written for Early Access and includes a visible update date. Treat exact values as tracking notes until the current build is field-tested.
Does this page use official screenshots?
Pages combine attributed official Steam / Unknown Worlds media, local gameplay frame captures, and source-video evidence cards. New player-submitted captures should keep the route, timestamp, and build context attached.

Near starter shallows
Approx. 70-120m from pod
Confirm oxygen before leaving the first landmark. The route is much safer when you mark the return path before collecting side materials.

Creature patrol ranges and fragment placement can shift between builds, so treat exact distances as field estimates until multiple players confirm them.
