Anomaly Zones reward route discipline over speed: warped geometry forces your path, and the extraction choice at the end decides whether the dive funds your next upgrade.
At a glance
Anomaly Zones, also called Otherworlds, are spaces that appeared suddenly in Japan in the year 20XX.
Warped geometry includes inverted gravity, floating furniture, one-way doors, and anomaly walls that force routes.
Extraction is a choice: ammo and grid backpack slots are limited, so choose what to carry back.
Dive Reports unlock after defeating Anomalies; the verified archive screenshot shows entries 008-019.
Lore totals 200+ entries; full collectible locations are unpublished.
Scope: demo-verified and officially confirmed content only; endings, achievement lists, and full collectible lists arrive after launch

Quick answer
Read the room before you move: inverted gravity and floating furniture signal a space that does not follow normal layout rules.
Treat one-way doors and anomaly walls as route locks, and plan a path that does not depend on going back the way you came.
Leave room in the backpack for the recovery that matters most, since large items take multiple grid slots.
Use Dive Reports as earned knowledge: each report follows a defeated Anomaly and records its ecology.
1. What Anomaly Zones are
In the year 20XX, Anomaly Zones appeared in Japan without warning. They are also called Otherworlds, and their look pairs Showa-era Japan with liminal-space aesthetics: familiar places rendered strange, empty, and slightly wrong.
Reona enters these zones as a Diver for the government-backed Anomaly Zone Countermeasures Office, searching for her missing friend Arisa. That mission frames exploration as retrieval work: fight Anomalies, recover items, and return to base with something useful.
2. Warped geometry: read the space, then move
Warped geometry is the zone's main puzzle language. Inverted gravity and floating furniture break the assumption that floors, ceilings, and furniture stay where rooms normally put them. A room that looks decorative may be a route, and a route that looks direct may end at an anomaly wall.
Two structures force route choices. Some doors open one way only, so a path taken cannot be retraced. Anomaly walls block passages and force a different route. Demo previews describe exactly that pattern in the hospital level: single-direction doors and anomaly walls shaping a forced route through the zone.
3. Extraction discipline: choose what to carry back
The official loop is Dive, Retrieve, Return, and the return step is a decision. Ammo is limited and the backpack is a grid, with large items taking multiple slots. Carrying an extra gun adds an option, and it also adds an ammo burden, so the loadout for the way out deserves as much thought as the loadout for the way in.
Preview reporting sharpens the point: the demo offers more weapons than its ammo supply comfortably supports, so firing without restraint drains the run. Pick a primary plan, keep ammo for it, and treat recovered materials and upgrades as cargo with a slot cost.
4. Dive Reports and the Anomaly archive
Dive Reports are lore entries unlocked by defeating Anomalies, recording each creature's ecology. They sit inside a larger lore set of 200+ entries, which also covers investigation material beyond individual creatures.
The verified archive screenshot shows entries 008-019. Its detail panel covers Tracer, Anomaly 018, listing area Yotsubadai Heights and material Hallucinated Body. This guide describes only what that screenshot shows, and it claims no total anomaly count, since the visible range is a window into the archive rather than a complete census.
5. Lore: 200+ entries, locations deferred
The lore total is 200+ entries, including Dive Reports. That scale makes lore a long post-launch project: reports arrive through combat, and investigation material arrives through exploration. The complete lore location list is unpublished, so this guide records the total and the unlock mechanism, and defers the location table to post-launch verification.
FAQ
What is an Anomaly Zone?
An Anomaly Zone, also called an Otherworld, is a warped space that appeared suddenly in Japan in the year 20XX. Its look pairs Showa-era Japan with liminal-space aesthetics, and its geometry does not follow normal room rules.
How do I get a Dive Report?
Defeat the Anomaly. Dive Reports unlock after defeating Anomalies and record each creature's ecology in the archive.
How many Anomalies are there in total?
This guide claims no total. The verified archive screenshot shows entries 008-019, with a detail panel for Tracer (Anomaly 018). A total count is a post-launch verification item.
What should I prioritize when leaving a zone?
Materials and upgrades that fund Workshop development, plus enough ammo to reach the exit safely. Large items take multiple grid slots, so count free slots before committing to a heavy recovery.
