Tactical brief
How to use this guide in a real dive
Base Module Collectibles is useful when the player needs a repeatable decision path, not just a short answer. Start with the page objective, then compare the map anchor, the first evidence frame, and the current Early Access status before committing to a longer dive. This keeps the guide practical when Subnautica 2 routes shift between patches.
On the atlas, this guide is tied to Base Modules Cleanup Route. Treat that marker as a route anchor: Base-module completion anchor for rooms, utility parts, and workflow upgrades. The important player action is not simply reaching the dot, but using it to decide when to approach, what to scan or gather, and how to leave cleanly.
The first visual check is Module menu (00:27). Use that frame as the reading order for the rest of the article: identify the landmark, confirm the objective, then watch for the mistake that would force a reset. Base module collectibles are valuable when they improve workflow, storage, power, or Biolab space.

Field manual
Base Module Collectibles field manual
Built from the supplied route videos and local frame captures so the article teaches what to watch for, not only what to click.
Scan base modules that improve storage, power, crafting, and safe returns before chasing decorative or comfort unlocks. A readable base accelerates every later 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
Base scans
Scan utility modules before decorative modules.
Best entry habit
Scanner
Prioritize storage and power support.
Stop condition
Overbuilding before the base has stable power.
Place early modules where they reduce return friction.
What to watch in the videos
Pause on Module menu and identify the landmark, depth band, or objective state before following the next step.
Use Databox room to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Blueprint unlock as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Decision table
Overbuilding before the base has stable power.
Reset to the last confirmed landmark or objective state, then repeat only the route-critical step.
Ignoring storage layout until inventory becomes painful.
Use the video frame as evidence, but record entry, proof, and exit as separate notes.
Scanning modules but never crafting the ones that reduce travel time.
Return, craft, sort storage, or retest the route before turning this page into a longer objective chain.

Prioritize storage and power support.
Place early modules where they reduce return friction.
Keep decorative expansion for stable base sites.
Track missing modules by biome and structure type.
Guide notes
Utility beats style in the first base
The first base should make the map smaller. Storage, power, crafting, and vehicle support do that better than decoration.
Future module fields
Each module can later store scan source, fragment count, power need, build materials, and why it matters.
Risk controls
Common mistakes
These are the actions most likely to waste oxygen, lose the route, or turn a clean scan into a failed attempt.
Overbuilding before the base has stable power.
Ignoring storage layout until inventory becomes painful.

FAQ
Fast answers before you dive
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.
