Abiotic Factor weather event survival matrix: identify, protect, and recover

Scope and version note

Weather events temporarily change normal facility conditions. The current wiki lists Fog Phenomenon, Radiation Leak, Airborne Spores, Rolling Blackouts, The Black Fog, and Cold Snaps. This guide does not guarantee that one loadout solves every event. It provides a response order: identify the condition, stop avoidable exposure, use the matching protection, decide whether to terminate the event, and recover before resuming the route.

After one weather event ends, another cannot occur for four in-game days. After that cooldown, the source currently lists a 20 percent chance at 7 AM. Use those figures for readiness planning, not to promise the exact day of the next event.

Event response matrix

The source pages remain authoritative for current effect details. The table is a decision aid, not permission to cross a dangerous sector simply because the matching gear exists.

Response procedure

1. Stop at a defensible location instead of diagnosing the event while moving.
2. Read the event warning and match it to the current Weather Event source.
3. Equip only protection documented for that hazard.
4. Decide whether the objective is mandatory, short, and recoverable.
5. Mark the route back with stable landmarks or return to base.
6. After the event, repair equipment, replace consumed supplies, and restore the normal loadout before beginning another expedition.

The key choice is whether to continue. A prepared character may finish a short objective, while an optional farming loop is usually easier to postpone.

Base readiness before an event

Keep hazard equipment in one labeled storage area, not scattered across general crates. Place spare lighting and navigation supplies near the exit used most often. Maintain a clear indoor path between storage, repair, rest, and food so the base remains usable when visibility is poor or outside travel is unsafe.

Do not leave critical protective gear on a distant expedition kit. A weather event is a readiness test: if the correct item exists but cannot be found, the storage system has failed.

Keep a second checklist for powered infrastructure. During Rolling Blackouts, inspect the Crafting Bench, refrigeration, lighting, and defenses before optional machines. A powered bench with Portal Suppression Field can remove nearby small Power Leeches, but the event still requires finding and destroying the Giant Power Leech to end it.

For Fog and Black Fog, route knowledge is the scarce resource. Mark the nearest safe room and the first two turns from the base before an event occurs. Normal Fog itself is described as harmless water vapor, but reduced sight and event enemies can still turn an unfamiliar corridor into the actual threat.

Failure and recovery checks

• The event name is unclear. Return to a controlled area and read the warning rather than inferring the hazard from color alone.
• Protection is damaged or missing. Do not test whether healing can replace environmental protection.
• The player loses the route in fog. Backtrack to the last confirmed landmark; do not turn a short objective into blind exploration.
• The event ends during a run. Recheck health, equipment, and route state before assuming all consequences ended immediately.

Completion condition

The response is complete when exposure has ended, the player can identify the return route, damaged equipment is handled, and the next expedition uses its normal kit again. For radiation-specific recovery, continue with the radiation protection guide. For base layout, use the storage layout guide.

Write an event card for the base

Create one short card for each confirmed event: warning name, first protective action, equipment storage location, safe indoor checkpoint, and the condition for resuming travel. Keep it beside the hazard equipment. This converts a wiki description into a response that another co-op member can follow without asking who moved the mask or radiation gear.

Review the cards after a version update. Compare the current Weather Event page with the specific hazard page, then change only details that the sources support. Do not update lastUpdated because an event occurred in a save; update it when the published instructions or their evidence actually changed.

During an event, note whether the selected shelter, route marker, and protective item worked. An observation from one save can improve the local base plan, but it should not become a universal mechanism claim unless the source confirms it. That separation allows practical learning without publishing speculation as a rule.

Common Mistakes

Choose shelter or termination

Terminating an event is worthwhile only when the route to its control is safer than waiting. Use this decision order:

1. Identify the event from its warning and visible effects.
2. Equip the documented protection before leaving storage.
3. Confirm the termination control is already reachable in this save.
4. Compare the control route with the base's current supplies and visibility.
5. If the route is not controlled, shelter and postpone optional work.
6. If the route is controlled, send a prepared group, activate the objective, and confirm normal conditions before restoring the ordinary loadout.

This avoids two opposite mistakes: treating every event as a reason to remain idle, or turning a survivable event into a dangerous cross-facility sprint. The correct answer depends on unlocked shortcuts and current gear, not only the event name.

Reopen travel deliberately

When the warning clears, do not send the full group out at once. One prepared player can verify visibility, the nearest landmark, and the normal return path while the rest keep the base stable. Resume the postponed objective only after the event-specific protection is stored, ordinary route equipment is restored, and no player is still managing an exposure effect.

Record the event name and the response used, but omit an exact duration unless the current event source states it. The useful result is a verified action card, not a timer inferred from one occurrence.
