Background

That's Not My Neighbor, developed by Nacho Sama, became a breakout indie horror hit by blending the meticulous document-checking gameplay popularized by Papers, Please with an unsettling premise straight out of a Cold War-era dystopia — verifying whether the person at your door is truly your neighbor or a shapeshifting impostor. That combination of careful, methodical verification work with mounting horror tension gave it a genuinely distinct identity within the crowded indie horror space.

The game builds dread not through jump scares but through the ever-present pressure of being watched and judged for every decision, forcing players to weigh the moral and practical consequences of turning away someone who might be entirely innocent — or might not be.

How to Play

• Mouse — examine visitor documents and compare them against provided guidelines.
• Check IDs and details carefully to identify inconsistencies suggesting an impostor.
• Decide whether to admit or deny each visitor based on your findings.
• Manage the consequences of your decisions as the story progresses.

Goal & Purpose

The objective is to correctly identify and turn away impostors while admitting genuine neighbors, using careful document verification under mounting pressure and uncertainty.
