Quick answer
Do not treat leviathan-class zones as normal resource routes. Enter with an exit plan, scan from controlled angles, and leave as soon as the objective is complete.
Second-screen dive plan
What to do, what proves it, and when to leave
Observe the zone edge before diving in.
Class recognition at 00:26
Observe from cover, record patrol direction, keep the exit lane open, and leave before curiosity becomes inventory loss.

Tactical brief
How to use this guide in a real dive
Leviathan-Class Threats 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 Leviathan Class Scout Line. Treat that marker as a route anchor: Scout-line anchor for observing leviathan-class patrols before committing to scans or objectives. 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 Class recognition (00:26). 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. Use size, silhouette, and movement line to separate Leviathan-class threats from ambient fauna.

Field manual
Leviathan-Class Threats 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.
Do not treat leviathan-class zones as normal resource routes. Enter with an exit plan, scan from controlled angles, and leave as soon as the objective is complete. Use this threat 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
Severe
Observe the zone edge before diving in.
Best entry habit
Reliable mobility
Mark a return path and a fallback shelter.
Stop condition
Trying to gather everything in one pass.
Complete one objective per entry.
What to watch in the videos
Pause on Class recognition and identify the landmark, depth band, or objective state before following the next step.
Use Aggro posture to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Route breakaway as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Decision table
Trying to gather everything in one pass.
Reset to the last confirmed landmark or objective state, then repeat only the route-critical step.
Entering with valuable materials in inventory.
Use the video frame as evidence, but record entry, proof, and exit as separate notes.
Assuming a large creature has a fixed safe pattern before verification.
Return, craft, sort storage, or retest the route before turning this page into a longer objective chain.

Creature threat matrix
Behavior cue, safe action, and route impact
Creature pages need more than names. This matrix tells players when to observe, avoid, scan from cover, or abort the route.
Collector Leviathan
Behavior cue
Readable side pass with retreat lane still open
Safe action
Approach from outside the patrol path, scan briefly, leave.
Route impact
Turns biomod scouting into a timed approach problem.
Retest reason
Scan windows and patrol routes can shift with patches.
Shiver Leviathan
Behavior cue
Shelter line available and creature not rotating toward you
Safe action
Use shelter as the landmark, cancel scan if the angle closes.
Route impact
High-risk scan route that should never start in open water.
Retest reason
Threat tuning can change approach and retreat timing.
Great Jaw Leviathan
Behavior cue
Large silhouette or open-mouth landmark near route edge
Safe action
Mark the sighting, verify the band, and do not chase the body.
Route impact
Forces route planning around a recognizable danger landmark.
Retest reason
Location reports should be rechecked after map updates.
Deepwing Brooder
Behavior cue
Late-route deep threat with poor recovery margin
Safe action
Treat the first sighting as a turn-back signal unless prepared.
Route impact
Changes deep exploration from resource run to threat scouting.

Behavior, depth band, and route pressure need current footage.
Hammerhead
Behavior cue
Vehicle interest or repeated approach pattern
Safe action
Keep the Tadpole pointed out, test mitigation once, then leave.
Route impact
Makes vehicle parking and noisy route choices matter.
Retest reason
Hotfix notes already mention behavior changes.
Marrowbreach
Behavior cue
Short attack cadence and damage pressure
Safe action
Do not test damage while carrying route-critical inventory.
Route impact
Turns narrow routes into damage and oxygen checks.
Retest reason
Damage and attack spacing have been tuned.
Nibbler
Behavior cue
Small fauna circling or interrupting scan/resource timing

Small threats matter when oxygen and inventory are already low.
Retest reason
Perception, circling, speed, and tool sensitivity changed.

Guide notes
Use edge scouting first
The edge of a threat zone teaches movement, visibility, and exit options with less risk than pushing straight to the center.
What to record for later verification
Future field-tested versions should record patrol range, trigger distance, escape terrain, and the safest scan window.

Common mistakes
These are the actions most likely to waste oxygen, lose the route, or turn a clean scan into a failed attempt.

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.
