What is Year Unknown?

This first-person adventure takes place in the Library, an archive as large as the universe. You explore brutalist spaces and talk to AI guides through terminals, choosing whom to consult and what information to share. The story branches around your decisions as you investigate a distress call from the center of a deteriorating universe.
