Shuumatsu Shelter Seikatsu

In a post-apocalyptic world where civilization has collapsed, the protagonist—a shelter company employee with a lifelong passion for building secret bases—must navigate survival in his custom-built underground shelter. With supplies dwindling and society descending into chaos and violence, he encounters a handful of women who have managed to survive the devastation. The core gameplay revolves around resource management and decision-making: will he remain isolated to preserve his limited provisions, or will he invite these women into his shelter, risking his own survival but potentially forming bonds in a nightmarish new world. The game blends survival simulation with social dynamics as the player determines how long they can endure in their dream shelter turned into a hellish crucible.
