Keep the Door Locked Dead Doppelganger Visitor

What a dead doppelganger looks like

The dead doppelganger is a confirmed visitor anomaly in Keep the Door Locked. The door knocks like any other visit, but the hallway camera reveals a second, lifeless figure lying near the staircase beside the standing visitor. The standing visitor speaks normally and asks to come in; the second figure is the anomaly evidence. The door decision is the only thing that matters.

A dead doppelganger looks similar to a regular doppelganger at first glance. The key difference is where the second figure lies. A doppelganger slumps against the wall; a dead doppelganger lies near the staircase, often partly out of view. The camera must cover the base of the stairs to confirm either anomaly.

How to spot it on the hallway feed

1. Pull up the laptop and open the live camera.
2. Look at the base of the staircase.
3. Look for a second, lifeless figure.
4. If you see one, lock the door without delay.
5. If the staircase is out of frame, treat the visitor as unknown and refuse by default.

The hallway camera is wide enough to show the staircase base, but the dead doppelganger is sometimes partially hidden by railings or shadows. If you cannot see the staircase clearly, the safe move is to refuse the visitor. The dead doppelganger is fatal if accepted.

Mistakes to avoid

• Confusing a dead doppelganger for a normal visitor because the camera is dark.
• Trusting the standing figure’s claim because they sound sincere.
• Deciding from a partial frame where the staircase is cut off.

Why the staircase is the tell

The dead doppelganger appears specifically near the staircase to make the camera habit more demanding. Players who only check the centre of the hallway or the wall beside the visitor can miss the second figure entirely. Practice scanning the whole hallway — wall, centre, staircase base — on every visitor.

Build the camera habit into a single ritual: doorway, wall, centre, staircase base, edge. Once you have done the full sweep a few times, the order becomes automatic.

Related visitor anomalies

• Translucent guest: the visitor is see-through.
• Doppelganger: the second figure slumps against the wall.
• Dead doppelganger: the second figure lies near the staircase, lifeless.

All three are camera-only tells. Build one habit and apply it to all three. The threat ranking compares camera-anomalies to room-anomalies so you can plan a calm practice night.

Sample encounter

A knock arrives and the peephole shows a tired traveler. You open the laptop and switch to the hallway camera. The traveler is standing at the door, but a second, motionless figure is slumped beside the staircase, face down. That second figure is not a shadow and not a guest. It is the dead doppelganger. The live visitor at the door may be ordinary, but the rule still holds: a confirmed dead doppelganger means the visitor is an anomaly and the door stays locked.

Combine with other signals

Dead doppelgangers sit beside the doppelganger and translucent guest in the camera tell group. All three require the laptop feed. They also overlap with the door breaker because each encounter can end the run quickly if you skip the camera check, so pairing the camera habit with a door discipline habit keeps both threats under control.

Build the habit

Practice the rule on ordinary nights: open the laptop, look at the wall, then look at the staircase, then look at the door. Build the sequence until the staircase frame becomes part of every check. A two-second glance at the staircase is enough to catch the second figure even when the live visitor is talking to keep your attention.
