Athanasy

Athanasy is a visual novel set in an underground City — the unnamed last refuge of humanity after the surface of Earth became uninhabitable. The City is a working megastructure of steel, concrete, and biopolymers, engineered to keep what's left of civilization alive one floor at a time.

Josiah Kaviani, a young mathematician and statistician, lives in the City's cramped streets as a quietly brilliant but unbearably lonely man. The story begins when he has a fateful encounter with someone — or something — that exists below even the City's lower levels, in places the structure itself cannot reach. The knowledge of what he meets is the kind that can kill the people who learn it.

The game leans into biopunk and body-horror as its primary registers, with science-fiction underpinnings drawn from real biological research. Choices throughout the story can take it to unexpected endings, and the full range tilts from bad to worse — the developer notes that some ideas were censored for being too dark, but most made it through. Five to ten hours of playtime, atmospheric original soundtrack, and an in-game gallery that tracks your progress through the available paths.
