Tactical brief
How to use this guide in a real dive
Creature Safety Index 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 Creature Safety Index Hub. Treat that marker as a route anchor: Creature behavior lookup anchor for observe, avoid, scan, or abort decisions. 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 Hostile cue (00:24). 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. Creature pages should teach the first readable hostile cue, not only the final attack.

Field manual
Creature Safety Index 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.
Use the Creature Safety Index before entering a threat band. Identify the creature, read the behavior cue, choose the safest action, and update the page after patches change behavior. 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
Safety lookup
Identify the creature or silhouette before moving closer.
Best entry habit
Scanner habit
Check whether the safe action is observe, avoid, scan, or abort.
Stop condition
Using creature pages as collectible checklists only.
Use the behavior cue to decide whether the current window is safe.
What to watch in the videos
Pause on Hostile cue and identify the landmark, depth band, or objective state before following the next step.
Use Close pass to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Route risk as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Decision table
Using creature pages as collectible checklists only.
Reset to the last confirmed landmark or objective state, then repeat only the route-critical step.
Ignoring small hostile fauna until oxygen is already low.
Use the video frame as evidence, but record entry, proof, and exit as separate notes.
Calling an encounter safe without recording retreat results.
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.

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

Hotfix notes already mention behavior changes.

Guide notes
Creature data should answer a player action
A useful creature database tells the player what to do next. Names and images are not enough; the page needs behavior cues, safe actions, and route impact.
How to use the matrix
Read across one row before entering the route. If the class says abort or scan from cover, prepare the return line before the objective.
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.

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.
