Evaluation

That's Not My Neighbor launched on March 11, 2025 as a fully featured job simulator with multiple game modes built in at release: Campaign Mode, Arcade Mode, Nightmare Mode, and Custom Mode. In the days immediately following launch, the developer shipped a series of patches (March 12–15, 2025) addressing bugs and making small quality-of-life improvements. These were all maintenance and polish patches, not new content additions. The developer has made no announcements of upcoming DLC, expansions, or additional content. There are no unreleased DLC listings on the store. The most recent official communication was on March 15, 2025, and no posts have appeared since. Given that the game launched as a complete, multi-mode experience and the developer has not signaled any plans for further content, this game appears to have shipped as a finished product.

About this game

The Department of Doppelganger Detection (D.D.D.) needs you!

Immerse yourself in the experience of working as a doorman in an apartment complex infested by beings that take on the appearance of your building's neighbors.

That's Not My Neighbor is a job simulator with science fiction elements and a slightly eerie aesthetic that will test your sense of observation and attention to detail.

Your job as a doorman is to allow or deny access to applicants seeking entry to your building. You will use tenants' documents and information to determine whether the applicant is truly human or not.

You will have the power to decide who enters the building and who is rejected or captured by the D.D.D. for extraction.

Include a variety of game modes: achieve different endings based on your performance in Campaign Mode, beat your score in Arcade Mode, test your skill in Nightmare Mode, and design your own tenants in Custom Mode.
