That's Not My Neighbor – Play Free Online
It is 1955, and the world has a doppelganger problem. Creatures that copy people's faces and voices are trying to get into apartment buildings—and you are the doorman who decides who walks through yours.
Each visitor hands over their papers and smiles through the window. Most of them are your neighbors. Some of them are not.
Tools at Your Desk
Security Window
Study the visitor's face. Doppelgangers often have tells—extra eyes, odd marks, or features that are just slightly off.
Documents and Checklists
IDs and entry requests come through the hatch. Cross-check names, apartment numbers, and details against your records.
Telephone
Call to confirm a visitor or reach the D.D.D. when something does not add up.
Entry and Emergency Buttons
Let a resident in, turn them away, or hit the emergency button when you are certain you are looking at a doppelganger.
What Is That's Not My Neighbor?
That's Not My Neighbor is a horror take on the document-checking genre, made by solo developer Nacho Sama. Think Papers, Please, but every mistake lets a monster into the building.
The doppelgangers are good, but not perfect. A missing detail, a face that is slightly wrong, a name that does not match the file—the clues are always there if you look closely enough.
How to Play
Everything is done with the mouse. Read the documents each visitor passes through the hatch, compare them with your records and the face in the window, then press the button to let them in or turn them away.
How to Catch Doppelgangers
- Look at the face before you look at the papers—the creepiest flaws are visual.
- Check every field on the ID: name, apartment number, and photo.
- Compare against the resident files, including who lives together.
- When in doubt, make the call before you open the door.
Speed matters, but one wrong decision costs more than a slow one. Take the extra second.
