that's not my neighbor is a chilling horror game that tests your observation, intuition, and nerves. Set in the eerie atmosphere of 1955, you play as a doorman in an apartment building where something sinister lurks behind every knock at the door. Your daily routine of checking IDs and letting residents in takes a terrifying turn when you realize that not everyone who shows up is who they claim to be. Doppelgangers—creepy impostors who look exactly like real tenants—are trying to infiltrate the building. It’s your job to stop them.
At first glance, the game seems simple: compare photos, names, and personal details from documents with the person in front of you. But as time goes on, things get stranger. Subtle differences in facial expressions, uncanny movements, and eerie sound cues hint at the truth. The impostors grow smarter, and the tension rises with every decision. One mistake could let a monster inside—or falsely accuse an innocent resident.
