Tactical brief
How to use this guide in a real dive
Bosses and Threats Overview 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 Boss Threat Overview Edge. Treat that marker as a route anchor: General threat-planning anchor for entering predator routes with an exit plan. 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 Attack read (01:43). 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. Read posture and turn direction as the warning that the route is no longer free.

Bosses and Threats Overview 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.
Prepare for major threats by scouting exits, carrying only mission-critical items, scanning from safety, and leaving before the encounter turns into a panic route. 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.
