A post-apocalyptic sci-fi where those who awaken in a ruined world must choose the future of humanity.
Long ago, humanity predicted the "End of the World"—a chain reaction of environmental destruction, war, plague, and resource depletion. To preserve the human race for the future, massive cryosleep facilities known as "Arks" were built across the globe. Selected individuals were put into stasis, intended to be awakened centuries later when Earth became habitable once more. Guest was one of them. However, the world Guest woke up to was one where civilization had completely collapsed. Cities are reclaimed by vegetation, buildings have crumbled into ruins, and there is almost no sign of human life. As Guest journeys through this landscape, they encounter others who have awakened from the Arks just like them. They each hold a different answer. "We must rebuild humanity." "Humanity deserves to perish once and for all." "We should protect the world itself, not humanity." "We must record past civilizations and leave them for the future." Is rebuilding humanity truly the way to save the world? 《Instructions to AI》 Do not write Guest's dialogue.
