HOUSE 13 How to Identify Impostors

How to identify Impostors is the HOUSE 13 search that matters most. The broadcast is explicit: things take the shape of people, wear their clothes, imitate their voices, and ask to be let in. Dread Forge is not hiding the fantasy. This page is the door-decision drill. Pair it with how to play so you know which button is which, and with getting started if you have not walked the house yet.

The rule that beats a tell list

If you are not sure, Close Door. Impostors are S-tier on the threat ranking because a false green has no recovery. A false red might cost you a help beat. Easy’s flavor text still wants verification, not charity. Medium and Hard punish charity harder because you have more nights to get generous at the wrong time.

What to look at

Clothes. Impostors wear stolen outfits. Look for layers that do not fit the weather, hats that sit wrong, or a uniform that does not match the story they imply. The official door screenshot shows a visitor in a hat and beard at night — that can be a person. It can also be a costume. Do not Let In because the outfit is “detailed.” Detail is the point of a copy.

Face and motion. Stare long enough to see whether the mouth and the voice line up. A copied voice with a dead face is a Close Door. Jerky idle, clipping through the porch, or a body that does not settle in the frame is a Close Door. HOUSE 13 is a Roblox horror; some jitter is engine. Persistent wrongness is a tell.

Voice. They imitate voices. A neighbor who sounds like they are reading the neighbor is not your neighbor. If you play with friends in co-op, agree on a live callout word that NPCs will not know. If the porch says the word, it heard you in voice chat — still Close Door, because an Impostor can stand there while a teammate is talking. Use the word only as a teammate check, never as a Let In proof.

Timing. Knocks during a Reacher climb, during a Hitcher sprint, or while you are in a closet are pressure. Pressure is a mechanic. Do not Let In to “get it over with” so you can go shut a window. Close Door, then shut the window. The survive the night order exists so the porch cannot skip the house.

What is not a tell

• A sad story. Impostors will have one.
• A familiar username-shaped NPC. The house is not your friends list.
• Chat saying “green.” Randoms grief.
• A script ESP color. No verified detector exists, and a wrong color is a wipe. See script safety.
• Terminal 13 passport logic. This prequel has no scanner plate.

Helping real strangers

The description asks if you will help fleeing people or open the door to something that is not a person. Identification is not “always red.” When clothes, voice, timing, and motion all sit still, Let In is the human play. That is how you keep the fantasy from collapsing into a locked box. Easy still wants you to answer knocks — Survived Easy says you answered them and lived. Answering is not the same as accepting.

If two teammates disagree, red wins. You can argue after morning. You cannot argue after an Impostor is in the dining room with The Nester already claiming a closet.

The video in the middle of this page is a HOUSE 13 walkthrough framed as fleeing strangers versus Impostors. Watch the door decisions, then close it. One video per page.

Practice plan

Run Easy and narrate every knock in one sentence: “clothes fit, voice matches, timing calm — green” or “voice late, red.” After six nights, your sentence speed should beat the Reacher window. If your sentence is always “idk green,” you are not identifying. You are gambling. Go back to how to play and make red the default.

HOUSE 13 is released and online. Impostors do not care that you have a wiki open. Keep this page for lobby reading. At the plate, you get two buttons and a few seconds. Use them.
