DON'T LET HIM IN Breach Survival: What to Do When the Creature Gets Inside

When DON'T LET HIM IN announces a breach, the creature is already inside the house with you and the lights are about to die. The official instruction flips from defense to endurance: "Hide. Stay quiet. Survive until morning." Your immediate job is to pick one of the two responses shown to work — swap places by getting outside while he's in, or get into an enclosed spot and stay silent — then run the recovery loop (wait him out, restore the breaker, survive the dark) until the clock passes 6 a.m.

This page starts where prevention ends. Once "Breach active" plays, it's too late to save the entrance; the doors-and-windows guide is where keeping him out is covered.

How the game tells you the breach happened

The breach is announced, not silent. As the creature gets in, the callout "Breach active." plays, and the game tells the occupants "You're all in there alone with him." One squad's session announced a second breach the same way later in the night, right as the power cut out — "Uh breach active." followed immediately by "He cut the power. We're standing right here." A solo player heard the same "breach active" message and immediately asked how to stop the breach — but there is no undo to search for in those first seconds. The callout means entry has already happened, so spend your reaction time on your response, not on the door.

What changes while he's inside

Three things switch at once, and knowing them is what makes the first minute survivable:

• The house goes dark. The official description is blunt — "If it gets inside, the house goes dark." Gameplay matches it: "Why is it so dark?", "I CAN'T SEE NOTHING WITH THIS FLASHLIGHT," and one player reduced to tracing the walls because "I literally can't see nothing."
• He hunts the occupants. He is in the building with you, and he closes in — "HE'S ON ME. HE'S ON ME." from one player caught in the open, and "Okay, he's inside. He's inside, bro. Okay, that's kind of bad, bro." from another.
• Furniture is not a guarantee. Don't count on a locker being around the corner: one breached layout had "no other lockers or closets, whatever, bro."

One more warning about reading the room: footsteps lie. As one solo player put it, "this guy could be on a whole different side of the house, but it will sound like he's like literally right beside you." Treat sound as a hint, not a tracker. More on how he moves is covered in the monster behavior guide.

Your first move: swap places or hide quiet

Both verified responses trade on the same fact: when he's inside, he isn't standing outside.

Option 1 — swap places: leave while he's in. One player turned this into a hard rule and executed it under pressure: "If he enters, I leave... He enters, I leave. That's it. Oh, it worked, it worked, it worked." The same tactic carried him through an entire night against The Boiled — "I managed to survive The Boiled, man." A solo player planned the same trade deliberately ("I'm going to wait for him to come inside and I'm going to go out"), and a Tagalog-speaking squad agreed on the trigger: "Kapag kapag kapag nandun siya sa loob tayo na yung lumabas" — when he's inside, we go out.

Be clear about what this is: a player-devised strategy shown to work in specific runs, not official instruction. The game intro says "You are to remain indoors until sunrise. Do not investigate unusual sounds." And outside is not automatically safe — it is just as black out there, and one player who made it out was still caught in the dark ("I just got murdered"). If you swap places, decide before the breach where you'll stand and how you'll get back in.

Option 2 — hide in an enclosed spot and stay quiet. This is the official post-breach instruction: "Hide. Stay quiet. Survive until morning." And it's shown working. A player ducked into a basement and lived through the encounter ("Dude, I'm going to hide in the basement here. Oh, I hid. I hid, I hid. Nice, nice, nice, man. I survived."). A group sheltered in a pantry — "Why do I feel like this is the safest spot?" — and the last player standing on one squad was the one who hid while everyone else got caught: "Minukbang ata sila lahat habang ako nakapagtago" (they all got caught while I hid) — "My god buhay pa ako" (I'm still alive). Squads pre-plan the handoff so nobody thinks during the blackout: "kapag nawala yung ilaw o magtago na" — when the lights go out, hide.

On noise, only the official "Stay quiet" guidance is verified. Players argued about whether sound actually draws him — one was told "You've been too loud, dude." and answered "I was being dead silent just then." Silence costs you nothing, so make it your default either way.

Since the hide depends on your house's layout — and some layouts barely offer one — the hiding spots guide breaks down location-by-location shelter choices.

Batteries decide the dark phase

During a blackout your flashlight is the only light you control, and batteries are the real currency of the night. One player's summary: "If you don't have any batteries, you just die." The survivors in these runs did three things:

• Stockpiled while they could — "let me grab as much batteries as possible."
• Rationed while he was loose — "I got to save my battery just in case."
• Swapped instantly when a cell died — "my battery does not work. Okay, grab this one."

Batteries also spawn as pickups inside the house — "That was a battery right there... I'm stealing mom's batteries." — so grab them while you can still see, not after the blackout starts. Exact drain rates and beam behavior are covered on the battery and flashlight pages.

Restore the power — only after he's out

Getting the lights back follows a fixed sequence, and step one is patience:

1. Wait for him to leave the house. The breaker can't be worked while he's inside: "He has to, he has to leave the house. He has to get out of the house so I can do this, man." Players confirmed the exit before moving — "He left, he left," "Okay, wait. I think he's gone." Remember the sound caveat above when you judge it.
2. Reach the breaker/fuse box. That usually means going back outside: "I had to go outside to flip the fuses back on." This is where the swap-places tactic and the repair step connect — he's in, so you can be out.
3. Complete the restoration minigame. A short minigame appears at the box ("Oh, there's a mini game." → "I did it. I did it.").
4. Mind your fuses. They're consumable, and running dry stalls the repair: "I have no more fuses."

Success is unmistakable: "Okay, we got the power restored." That puts you back under the official countermeasure — "Keep the floodlights powered. Watch the doors and windows. Restore the breaker when the power fails. Light keeps it away, but one vulnerable entrance is all it needs."

One caution before you relax: restoring power does not banish him. One player saw the creature vanish right after a restore — "So, apparently when I get the power, he just disappeared." — but in that same session he broke in again afterward, exactly as the player predicted ("He's probably about to break inside my house again." → "He's inside."). Treat the restore as getting your defense back, not as an exorcism. The loop is the plan, as one player put it: "As long as he runs out the house, I can grab the power, go back inside, and try and survive." The power system and floodlights pages cover the lit-phase defense in detail.

Hold the loop until 6 a.m.

There is no killing him — the night is survived, not won by force: "I have to survive until 6 a.m." The runs confirm the clock as the finish line. One player checked at 5:41 and saw "It's daytime." Another, restoring floodlights in the early light, counted down: "It's getting light out. 8 minutes left, man." A Tagalog squad closed it out: "May araw na eh. Tapos oh. 6 a.m. Perfect. So natapos namin yon." — there's daylight, 6 a.m., perfect, we finished it.

Sunrise itself ends the hunt — "Oh, the sun's up." — and reaching it is the win, confirmed by the return to the lobby: "See, that's what I call a win right there." / "We won." So the whole post-breach phase has one shape: survive the dark, swap or hide, wait him out, restore, repeat.

If teammates go down mid-breach

Squads have a recovery tool: revive totems. The purchase prompt reads "revive all fallen teammates. Buy the totem for 24." — a price shown without a currency label on the prompt. Totems also spawn in the world; one group grabbed one right next to their pantry shelter ("Look, there's a totem right here."), while another player had to hunt one down ("I can't find a revive totem. I think there's one in the shed outside.") — spawn spots varied between sessions, so don't rely on last game's location. Carrying one lets the living plan the pickup once the coast is clear: "I can revive Saxon when we got that back, though." There is also a separate revive option that costs Robux — "another revive? Oh, no, that costs Robux." — if you'd rather pay than wait.

Keep the loop and the hiding-spots guide open together: this page gives you the sequence for the whole house, and the hiding spots guide tells you where, exactly, to be when the lights go out.
