The core survival loop

Step

In short Every night comes down to light, doors, and knowing what to do when things go wrong.

The creature circles the house looking for a way in, and a single unguarded entrance is enough. Floodlights keep it at bay, so the power must never stay off for long. If the creature does get inside, the house goes dark and your options change fast.

Watch the entrances check every door and window regularly so nothing slips through while you are looking elsewhere.
Keep the power on floodlights are your main defence, so treat a power failure as an emergency.
Fix the breaker immediately when the power drops, get to the breaker and restore it before the creature finds an opening.
Hide and go quiet if the creature gets inside and the house goes dark, find cover and stay still until morning.
Survive until 6 AM that is the finish line every night, on every difficulty.

Difficulty order and what changes

Tips

In short There are four difficulties: Easy, Normal, Hard, and Nightmare.

There are four difficulties: Easy, Normal, Hard, and Nightmare. Clearing each one for the first time earns its own badge, and clearing all four unlocks the Conquer Your Fears badge.

Tips worth knowing

Hard is the minimum level required for several advanced badges.
Nightmare is the hardest single-night difficulty; solo clears and no-death runs have their own badges here.

Three monsters and how to handle them

Tips

In short Each creature has a different trick, so recognising it early changes how you respond.

The game features the Locust, the Boiled One, and the Skinwalker. Beating a full night against each one separately is tracked, and surviving against all three earns the Seen Them All badge.

Tips worth knowing

Repel the Locust at a door or window the moment it tries to enter — your first successful repel earns the Not Tonight badge.
If the Boiled One puts a teammate into a trance, wake them up immediately — the Snap Out of It badge is earned by waking a friend from the Boiled One's trance.
The Skinwalker disguises itself as a copy of a teammate and tries to walk in through an entrance — spot and stop it before it gets inside to earn the Not My Friend badge.

Co-op tools and team roles

Check

In short A crew that divides the house and communicates will almost always outlast one that plays separately.

Up to 30 players can share the same session. Voice chat is recommended as the fastest way to pass information.

Split the entrances between players so every door and window has someone watching it.
Carry a totem and use it on a fallen teammate the Nobody Left Behind badge confirms the revive worked.
Call out the Boiled One's trance so the nearest player can snap the affected teammate out of it.

Advanced badge challenges

Warn

In short These badges punish small mistakes and add an extra rule on top of surviving.

Several badges require Hard or Nightmare difficulty and add an extra rule on top of surviving.

Worth watching out for

Nowhere to Hide requires you to reach 6 AM on Hard or above without stepping into a closet once.

Lights Back On means you must survive an indoor hunt, then personally repair the breaker, then finish that same night on Hard or above all three steps in the same run.

No Second Chances on Nightmare leaves no room for error a single death or revive ends your attempt.

Everyone Comes Home needs a starting crew of at least four, all alive at dawn on Nightmare revives are allowed, but no one can be lost permanently.

Alone With Him is a full solo Nightmare night from start to finish, with no teammates to cover other entrances.

Endless mode milestones

Summary

In short Endless mode tests how long you can survive night after night.

Instead of a single night, Endless mode chains nights together. The two badge milestones give you targets to aim for.

Still Standing　survive five consecutive Endless nights without the run ending.
Overtime　push that streak to ten consecutive nights.

Glossary

Floodlight: The powered lights surrounding the house that keep the creature away — if the power fails, they go out.
Breaker: The switch you repair to restore power and bring the floodlights back online after a failure.
Totem: An item used to revive a teammate who has been taken down during the night.
Trance: A state the Boiled One inflicts on a player that a teammate must break by waking them.
Skinwalker: A monster that copies the appearance of a teammate and tries to pass through an entrance undetected.
Endless mode: A game mode where nights repeat back to back and your goal is to survive as many consecutive nights as possible.

Common questions

FAQ

Can I play solo?

Yes, you can play alone. If you complete a full Nightmare night solo from start to finish, you earn the Alone With Him badge.

What do I do if the creature gets inside?

When the creature enters, the house goes dark. Hide immediately and stay quiet until 6 AM. On Hard or above, if you can survive the indoor hunt and then personally repair the breaker before the night ends, you will earn the Lights Back On badge.

How do I spot the Skinwalker?

The Skinwalker disguises itself as a copy of one of your teammates and tries to enter through a door or window. Stop the copy before it crosses the threshold to earn the Not My Friend badge.

Do revives count against me for any badges?

Yes, for one specific badge they do. No Second Chances requires you to finish a full Nightmare night without dying or being revived at all. The Everyone Comes Home badge explicitly allows revives as long as no one is permanently lost.
