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 approach long enough to learn the exterior landmark; skipping straight to the door makes the route harder to repeat.
Pause at the entrance and compare the door frame, interior lighting, and vehicle/player position.
Inside, watch scan order. A clean sweep reads the room in layers instead of clicking every object randomly.
Approach route
The exterior frame gives the route context a player needs before entering a structure.
Action: Record the outside landmark and confirm the exit line before moving inside.
Door entry
The doorway is the last safe checkpoint before oxygen and interior orientation start competing.
Action: Pause, check supplies, then enter with a scan order instead of wandering.
Interior check
The interior frame shows why random scanning is inefficient: the room has layers, corners, and possible blockers.
Action: Sweep consoles, devices, unusual objects, and locked paths in order, then leave when the blocker type is known.

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
Treat the Old Habitat as a structure route: orient outside, confirm the entry and exit, scan interior objects in layers, and leave when a missing tool or story state becomes obvious.
Visual checkpoint
Use exterior terrain to orient before entering the Old Habitat route.
Map anchor
Old Habitat Entry Route in Old Habitat approach. Use it for use this before entering the habitat so you know which blocker you are trying to solve.
Abort rule
Entering the habitat without knowing the exit line.
Field manual translation
The Old Habitat is easiest when treated as a structure-reading problem. Players need visual confirmation without having every story beat spoiled. The useful order is exterior orientation, door check, interior scan sweep, blocker classification, then return with the missing tool or state. The screenshots support that rhythm while keeping the guide spoiler-aware.
Primary job
Enter, scan, classify blockers - The goal is not to clear every object in one breath; it is to understand what the structure currently allows.
Best entry habit
Exterior first - Use outside terrain and the entrance line as the return anchor before reading the room.
Stop condition
Inactive blocker - If a door, console, or room state clearly needs another unlock, leave and continue progression elsewhere.
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
- Scanner
- Oxygen margin
- Return route note
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

Approach from a visible exterior route and note the exit terrain.
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
Old Habitat reading order
Read the exterior first, then the entry, then the main room, then consoles and locked paths. This keeps the structure understandable and avoids wasted oxygen inside the wrong corner.
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.
Progression blocker checklist
If something does not react, ask whether the blocker is access, power, scan data, missing equipment, or story state. Naming the blocker is more useful than clicking every object again.

When to stop solving
The Old Habitat becomes frustrating when the player keeps testing an inactive room after the blocker is already clear. If the door, console, or device does not react after a clean scan pass, write the blocker down and leave for the next tool, story beat, or power-state clue.

Old Habitat pacing
Old Habitat routes are easiest when you treat the structure as a sequence of confirmations: exterior landmark, entry, scan target, interior clue, return point. Do not clear every corner on the first pass. Confirm the route, bank the unlocks, then return with more oxygen and a cleaner objective.

What to bring
Bring the tools that support reading the space: scanner, enough inventory room, and a return plan. If you are already full before entering, the route will punish every new discovery. Empty inventory is part of the preparation, not a convenience.

Video route notes
Old Habitat Walkthrough should be followed as a puzzle route, not as a memory test. Start by watching the first route movement and naming the entry condition before copying the path in-game. Approach from a visible exterior route and note the exit terrain. 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. Stop at the door and confirm the return path before entering. If the route starts to feel different in your build, keep the same player goal: separate room reading, device order, and exit timing.

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. Scan consoles, devices, and unusual objects in a consistent order. 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 state-change 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. Entering the habitat without knowing the exit line. Scanning randomly instead of reading the room in layers. 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 puzzle route into better field knowledge instead of another random interaction loop.

Common mistakes
Entering the habitat without knowing the exit line.
Scanning randomly instead of reading the room in layers.
Burning oxygen on a blocker that clearly needs a later unlock.
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.

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