In That’s Not My Neighbor: Nightmare Update, you step into the role of a doorman, but this isn’t just any building. Hidden among the regular residents are doppelgangers—creatures that flawlessly imitate human behavior. Your task is to examine IDs, cross-check personal details, and spot subtle discrepancies in their appearance or behavior. A single slip could mean letting a dangerous entity inside, putting everyone at risk.

Nightmare Mode: More Deceptive Than Ever

The Nightmare Update intensifies the challenge, adding smarter, more convincing doppelgangers who can easily fool even the most careful player. You’ll face distorted visuals, fake documents, and even residents who appear entirely normal until it’s too late. The pressure is on, and every choice counts—deny the wrong person, and you could anger a real tenant; let the wrong one in, and you might never see daylight again.

Your Decisions Define the Ending

With multiple endings influenced by your accuracy and choices, each playthrough offers a new experience. Whether you manage to keep the building safe or succumb to the horrors lurking at the door depends entirely on your skills. The Nightmare Update also introduces new story elements and hidden secrets, encouraging players to replay and uncover every dark twist.
