The Campaign Mode in That’s Not My Neighbor, released in the game’s Update 1.2.0.0, introduces a profound layer of strategy and depth that extends beyond the traditional gameplay of the original format. This mode, accessible only in the paid version of the game, is structured around a tightly woven narrative that unfolds over seven days, each bringing its own set of challenges and moral quandaries. As the player takes on the role of a doorman in an apartment complex, they are thrust into a suspenseful environment where the line between friend and foe is blurred by the presence of doppelgängers—entities adept at mimicking human appearance and behavior.
Campaign Mode challenges players with a gameplay that demands acute observation and critical thinking. Each day, the player receives a list from a D.D.D. agent that includes potential threats and instructions, setting the tone for the day’s security measures. The game’s tension is amplified by the introduction of doppelgängers who are nearly indistinguishable from the genuine residents, requiring the player to use all available tools and intuition to prevent breaches. The outcomes of the player’s decisions are significant and irreversible: allowing a doppelgänger access can lead to tragic consequences, permanently affecting the game’s dynamic and the player’s emotional investment in the safety of the apartment’s inhabitants.
