The Korean studio Project Moon's linked games. The management structure of the facility is the Tree: the department heads are named Malkuth, Yesod, Hod, Netzach, Tiphereth, Chesed, Gebura, Hokma, Binah, and the man at the top is Ayin — ayin, nothing, the name the tradition gives the unknowable source above all ten.

The most structurally committed use of the sephirot in any game, by a distance — the diagram is not decoration here, it is the org chart, the progression and the plot. And the naming of the CEO is the tell that somebody read past the diagram: putting Ayin above Keter and making him the source of the whole catastrophe is a real reading of a real doctrine, done in a game about managing monsters in a basement.
