Game stories

In the game, players face a world ravaged by "doppelgangers"—strange e entities with sinister motives that mimic human actions.
Players act as doormen—the first line of defense against these sinister forces—tasked with identifying and stopping doppelgangers trying to enter the building.


The game revolves around verifying the tenant's identity using multiple methods. From scrutinizing IDs to confirming apartment numbers and even calling to verify arrivals, players must use a variety of strategies to uncover the truth.

As they progress around the building, the player encounters increasingly suspicious characters, with every decision leading to different consequences. Making decisions requires absolute consideration.
