That’s not my Neighbor Campaign Mode

Game information

In That’s Not My Neighbor Campaign Mode, players are placed in the middle of a week-long investigation, working as a doorman responsible for keeping doppelgangers out of the building. Each day brings new faces to inspect, with residents returning for work, errands, or visits — but hidden among them are nearly perfect imposters. Unlike quicker game modes, Campaign Mode saves progress after each day, meaning every mistake builds toward a larger consequence as the week unfolds.

Permanent Losses and Increased Difficulty

Every wrong decision in Campaign Mode carries weight, with residents who fall victim to doppelgangers disappearing for the rest of the week. This not only reduces the building’s population but also removes valuable reference points that help players spot differences in future inspections. Doppelgangers are more deceptive than ever, with only minor differences in facial features, posture, or proportions giving them away. Players must sharpen their attention to detail, as overlooking even the smallest inconsistency can lead to deadly mistakes.

Shifting Outcomes and Unlockable Endings

Campaign Mode expands the game’s story by offering multiple endings based on player performance, with five possible outcomes waiting at the end of the week. Whether the player uncovers deeper secrets, protects the building successfully, or falls into a trap set by the doppelgangers depends entirely on the choices made across all seven days. Combined with escalating difficulty and unpredictable events, this mode adds long-term strategy and replay value, challenging players to perfect their observation skills with each new attempt.
