In this world, doppelgangers—creatures that mimic humans perfectly—are a persistent and terrifying menace. As the new guardian of a seemingly peaceful apartment complex, you’re responsible for ensuring the safety of the tenants by detecting and blocking these imposters before they infiltrate the building. This task, however, is anything but simple; failure to detect these intruders could turn you and the other residents into their next meal.

Game Setting and Storyline

Set against the atmospheric backdrop of a 1950s urban apartment building, the game plunges you into a dark era where the Doppelganger Detection Department (DDD) has been established to combat the eerie rise of these shape-shifting creatures. With few employment options, you accept a position as the apartment’s doorman, knowing full well the risks involved. Armed only with limited resources and your wits, you must use your powers of observation, intuition, and decision-making to keep doppelgangers at bay.

Objective and Gameplay

Your mission in That's Not My Neighbor is clear: protect the tenants by ensuring that only the legitimate residents gain entry. The game unfolds with individuals approaching the apartment’s entrance, each claiming to be a resident or visitor. They hand you documents for verification, which you must meticulously review for any inconsistencies or signs of foul play. Rely on these details, observe their behavior, and, when in doubt, call the apartment to verify if the person standing before you is indeed the real tenant.

Checking Documents

Each character approaching the building carries some form of identification, such as a photo ID, letter, or pass. Look closely at details like photo mismatches, name inconsistencies, or any other discrepancy that could suggest the individual is a doppelganger. The game’s simplicity in controls belies the complexity of keeping track of various tenants and their characteristics, making every decision you make feel like a high-stakes risk.
