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 route and identify the landmark, depth band, or objective state before following the next step.
Use Cargo test to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Upgrade menu as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Module route
Cargo upgrades should begin with a route that actually needs larger hauls.
Action: Decide which repeated haul route needs more storage.
Cargo test
Test the chassis on a planned material loop before using it for clutter.
Action: Follow the chassis fragment route and scan only unlock targets.
Upgrade menu
Menu proof separates a completed unlock from a route that still needs fragments.
Action: Check the vehicle or blueprint state after each scan.
Video route timeline
Turn the video into playable checkpoints
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
Get the Haul Chassis when repeated material runs are slowing progress. Scan the fragments, confirm the chassis unlock, then test the cargo value on one planned haul route.
Visual checkpoint
Cargo upgrades should begin with a route that actually needs larger hauls.
Map anchor
Tadpole Haul Chassis Anchor in Vehicle cargo route. Use it for use this when repeated hauls are slowing progress more than the chassis route would.
Abort rule
Unlocking cargo capacity before a real haul route exists.
Field manual translation
Get the Haul Chassis when repeated material runs are slowing progress. Scan the fragments, confirm the chassis unlock, then test the cargo value on one planned haul route. 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
Haul Chassis - Decide which repeated haul route needs more storage.
Best entry habit
Tadpole progress - Follow the chassis fragment route and scan only unlock targets.
Stop condition
Unlocking cargo capacity before a real haul route exists. - Check the vehicle or blueprint state after each scan.
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 progress
- Fragment route
- Cargo use case
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
Decide which repeated haul route needs more storage.
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
vehicle cargo upgrade route plan
Tadpole Haul Chassis 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: vehicle cargo upgrade
Proof to confirm: Haul Chassis fragment or module unlock
Primary blocker: Tadpole progress
Best follow-up: Test the upgrade on a planned material route, not random gathering.
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 Haul Chassis fragment or module unlock
Exit frame: return before adding side goals

Stop rule
Stop after the chassis is unlocked and tested on one known haul; cargo upgrades should reduce route time, not encourage clutter. 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
Tadpole Haul Chassis 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. Decide which repeated haul route needs more storage. 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. Follow the chassis fragment route and scan only unlock targets. 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.

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. Check the vehicle or blueprint state after each scan. 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

Stop rule and next dive
The most useful part of this page is the stop rule. Unlocking cargo capacity before a real haul route exists. Filling the larger vehicle storage with unsorted clutter. 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.

Common mistakes
Unlocking cargo capacity before a real haul route exists.
Filling the larger vehicle storage with unsorted clutter.
Ignoring depth or threat pressure because the vehicle carries more.
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.

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.
