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
Watch the route into the databox area before focusing on the unlock screen.
Pause on the Square Room unlock and check whether the blueprint state is complete.
Compare the room value against base storage, crafting, and power needs.

Databox route
The route frame makes the databox repeatable instead of a one-time lucky find.
Action: Record the landmark and return path before interacting with the box.

Room unlock
The unlock frame is the evidence that the page needs to show clearly.
Action: Check blueprint completion and leave before turning the route into broad looting.

Base expansion
The expansion frame should be judged by workflow, not room size alone.
Action: Build around storage lanes, power reach, and future scanner or biolab needs.
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 Square Room when cramped base layout becomes a workflow problem. Follow the databox route, confirm the unlock, return to stable power, then build the room only if it improves storage, crafting, or Biolab planning.
Visual checkpoint
Square Room routes should start with the databox context and a clean return line.
Map anchor
Square Room Databox Check in Base expansion databox route. Use it for use this when hallway bases are slowing crafting, sorting, or research flow.
Abort rule
Chasing Square Room before the starter base has power and storage.
Field manual translation
Square Room is a base workflow unlock. The footage should be read in three parts: reach the databox route, confirm the room unlock, and decide whether expansion actually solves base friction. A big room without power, storage, or a layout plan is just a larger problem.
Primary job
Unlock useful room space - Use the room when hallway bases start slowing crafting, sorting, or research.
Best entry habit
Databox proof - The databox and unlock state are more useful than a vague structure description.
Stop condition
Power not ready - Return after unlock and build only when base power and materials can support expansion.
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
- Safe route
- Databox check
- Base power plan
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 whether the current base actually needs room space.
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
Room space should solve friction
Square Room is useful when it makes storage, crafting, or research easier. If it only makes the base larger, it can wait behind power and scanner workflow.
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.
Databox evidence
The route note should include the room, databox, unlock screen, and return path. That is enough for a player to repeat the route without needing every coordinate.

Practical field read
Square Room Blueprint Guide works best when you treat it as a completion route with a narrow job. Start with the loadout check: Safe route. Then follow the first action without adding side goals: Decide whether the current base actually needs room space.. The page should help you recognize the scan, pickup, or checklist state that proves progress before you risk a longer dive. If the route starts producing unrelated discoveries, bank the note and return to the original objective instead of turning one guide into a full map sweep.
Loadout check: Safe route

How to turn this into the next dive
After the first proof point, decide whether the route is solved, blocked, or worth repeating. Follow the blueprint route and identify the databox area before searching.. If it is solved, return and convert the result into crafting, storage, a map note, or the next related guide. If it is blocked, change only one variable: bring the missing tool, clear inventory, enter from a cleaner landmark, or wait for better oxygen and vehicle support. Open the databox and confirm the Square Room unlock state.. Avoid the two habits that make this route feel unreliable: Chasing Square Room before the starter base has power and storage.; Opening the databox but not checking whether the unlock completed..

Video route notes
Square Room Blueprint 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 whether the current base actually needs room space. 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 blueprint route and identify the databox area before searching. 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. Open the databox and confirm the Square Room unlock state. 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.

Stop rule and next dive
The most useful part of this page is the stop rule. Chasing Square Room before the starter base has power and storage. Opening the databox but not checking whether the unlock completed. 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
Chasing Square Room before the starter base has power and storage.
Opening the databox but not checking whether the unlock completed.
Building a large room that makes the base harder to navigate.
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.
Guide-wide
N/A
Creature patrol ranges and fragment placement can shift between builds, so treat exact distances as field estimates until multiple players confirm them.
