That’s Not My Neighbor Campaign Mode

In Thats Not My Neighbor Campaign Mode, players take on the role of a doorman working for an apartment complex under the supervision of the D.D.D. agency. Over the course of seven days, players must check the identity of every visitor trying to enter the building, using a combination of documents, facial features, and small behavioral clues. Some visitors are ordinary residents, but others are dangerous doppelgangers — creatures trying to sneak inside by mimicking the appearance of real neighbors.

Every Choice Leaves a Mark

Unlike shorter modes, Campaign Mode tracks every decision across all seven days, and mistakes have long-term consequences. If a player allows a doppelganger inside, it doesn’t just end the shift — it permanently affects the building’s population. If a resident dies, their apartment stays empty, and their absence changes how future days unfold. This means every approval or denial shapes both the story and the difficulty, as fewer neighbors mean fewer safe arrivals to compare against the growing number of imposters.

Multiple Endings and Uncovering the Truth

With five different endings, Campaign Mode adds a deeper layer to the experience by tying the player’s performance to how the story concludes. Whether the building stays safe or falls to the doppelgangers depends entirely on how accurately players detect the imposters. Small details, such as facial proportions or slightly incorrect documents, become critical clues in determining who gets through the door. This blend of observation, pressure, and branching outcomes makes Campaign Mode a more complex and rewarding version of the core game.
