[Apocalypse + Rebirth + Survival through destruction + Infrastructure fortress + Stocking up + Various forms of human nature]
The apocalypse is coming, the world is paralyzed, others are struggling in the wasteland, and I am basking in the sun on the top floor and looking at the scenery. Country settled in? Full management rights, leave me alone! Someone is causing trouble? The defense system teaches you how to be a good person with one click! Occasionally, a soft-hearted and kind-hearted survivor will leave an ark for mankind, survive, and be happy!
