Unlock priority board
Databoxes, scans, and what they enable
Collectibles are ranked by practical value: base workflow, vehicle depth, scanning, storage, and repeat route efficiency.
Habitat Builder
Storage, fabricator workflow, power, and safer return loops
Return immediately after the unlock and place a compact base.
Square Room
Biolab space, organized storage, and less cramped crafting flow
Leave after the room unlock and build only if power can support it.
Room Blueprint
Functional base expansion and specialized module layout
Confirm the room state, then return before side-room drift.
Modification Station
Upgrade crafting, stronger route prep, and deeper progression
Stop after the required fragments and craft the station before pushing deeper.
Scanner Station
Targeted resource runs and blueprint cleanup from a working base
Use one filter per blocker and stop once that blocker is solved.
Metal Farm
Repeatable base expansion material flow
Judge the farm by repeat value before spending base resources on it.

Collectibles Overview
A completion-focused overview for lore logs, PDA entries, blueprints, rare materials, and base module finds.
Track collectibles by type and route, not by memory. Separate story logs, blueprint unlocks, rare materials, and base modules so completion checks stay readable after patches.
Collectibles Overview Sweep
VariableUse this when you want a checklist route instead of re-searching every biome.
PDA and Lore Logs
How to track PDA entries, environmental storytelling, lore logs, and missed narrative clues without over-spoiling the route.
Track lore logs by region and story beat. Avoid reading ahead if you want discovery, but keep a completion list so missed entries can be revisited later.
PDA and Lore Log Shelf
300m - 700mUse this when you want to clean up logs while preserving story discovery.
Blueprint Collectibles
A blueprint collection framework for scanner unlocks, crafting progression, base modules, and vehicle upgrades.
Blueprints matter most when they unlock new routes. Prioritize scans tied to oxygen, movement, storage, power, vehicles, and base expansion before completion cleanup.
Blueprint Collectibles Chain
350m - 850mUse this when scan fragments are available but you need to know which ones affect progression.
Rare Materials Tracker
A versioned tracker for rare materials, where to record them, when to spend them, and how to avoid waste.
Treat rare materials as route keys. Store them separately, label the source region, and spend them only when the recipe clearly unlocks depth, mobility, power, or story access.
Rare Materials Deep Cache
650m - 1,000mUse this when rare drops start blocking upgrades and storage labels need discipline.
Base Module Collectibles
How to track base module scans, useful habitat unlocks, and the difference between comfort modules and progression modules.
Scan base modules that improve storage, power, crafting, and safe returns before chasing decorative or comfort unlocks. A readable base accelerates every later route.
Base Modules Cleanup Route
180m - 520mUse this when your base works but missing modules are slowing storage, crafting, or research flow.
All BioMods and Adaptations Guide
A practical BioMods and adaptations guide for tracking unlocks, route value, hazard answers, and upgrade priorities.
Treat BioMods as route-solving upgrades. Scan the unlock, identify the hazard or blocker it answers, equip only what supports the next dive, and record which biome or structure made the adaptation necessary.
BioMod Adaptation Route
650m - 1,000mUse this when a heat, depth, oxygen, or threat blocker suggests an adaptation instead of brute force.
Scanner Station and Filters Guide
How to unlock, use, and think about Scanner Station filters so resource and blueprint routes become repeatable.
The Scanner Station is valuable when it turns guesswork into filter-driven routes. Use it to check what a biome can provide, then leave base with one target instead of sweeping randomly.
Scanner Station Filter Hub
300m - 650mUse this when manual searching is slower than building a focused filter workflow.
Equipment Blueprint Locations
A blueprint route guide for equipment unlocks, databox checks, scanner stops, and post-route crafting priorities.
Treat equipment blueprints as route unlocks: scan or open the databox, confirm the blueprint menu, return to craft, and only then decide whether the route should continue.
Equipment Blueprint Sweep
450m - 900mUse this when equipment gaps are blocking a route more than raw materials are.
Room Blueprint Location Guide
A room blueprint guide for data boxes, base expansion planning, biolab space, and practical layout decisions.
Room blueprints matter when your base needs more usable layout space. Find the databox, confirm the unlock, return to base, and build only the room that solves your storage, crafting, or lab problem.
Room Blueprint Databox Route
420m - 780mUse this when the base needs functional room space rather than more hallway pieces.
Inventory Expansion Upgrades
How to find and prioritize inventory expansion upgrades so material routes become longer, safer, and less wasteful.
Inventory upgrades should be treated as route upgrades. Each expansion lets you bring home more useful materials, reduce forced returns, and revisit routes that were previously too slot-limited.
Inventory Expansion Upgrade Route
500m - 900mUse this when inventory capacity is the bottleneck on known resource routes.
Sonic and Feedback Resonator Upgrades
A practical Resonator upgrades guide for unlock routes, adaptation synergy, threat response, and route safety.
Treat Resonator upgrades as safety tools. Unlock them through a controlled route, test what they change against a known threat or blocker, and update your loadout before returning to deeper zones.
Resonator Upgrade Test Zone
650m - 980mUse this when a threat or route needs tool response instead of faster swimming.
Necrolei Cyst Guide
How to approach Necrolei Cyst collection with source recognition, route safety, and farming discipline.
Treat Necrolei Cyst as a targeted farm: confirm the source, collect only the amount tied to a recipe or upgrade, and leave once the loop is proven repeatable.
Necrolei Cyst Farm Loop
650m - 980mUse this only when a recipe asks for the cyst; otherwise the route is a distraction from progression.
Modification Station Blueprint Guide
A scan-first Modification Station guide for fragment counting, equipment upgrades, craft timing, and avoiding repeated structure sweeps.
Treat the Modification Station as an upgrade gate. Scan only confirmed fragments, check blueprint progress after each scan, and return to craft once the station unlocks instead of widening the sweep.
Modification Station Fragment Sweep
520m - 880mUse this when an upgrade is blocked and you need the station before another deep route.
Square Room Blueprint Guide
A base-expansion guide for finding the Square Room blueprint, confirming the databox, and using the unlock without overbuilding.
Get the Square Room when cramped base layout becomes a workflow problem. Follow the databox route, confirm the unlock, return to stable power, then build the room only if it improves storage, crafting, or Biolab planning.
Square Room Databox Check
420m - 780mUse this when hallway bases are slowing crafting, sorting, or research flow.
