The Ever-Expanding Bunker is a community-driven collaborative world-building project that originated on Reddit around 2020. Utilizing the 6x6 or 9x9 Political Compass grid format, users create intricate maps of a massive underground facility following a surface-level cataclysm. Each cell represents a different faction, character, or horror, governed by the mysterious and often malevolent 'Computer.' It has evolved from a simple meme into a massive lore-rich universe, blending elements of cosmic horror, authoritarian dystopia, and dark sci-fi, allowing creators to explore themes of isolation and societal decay through a unique visual medium.
