About HolyOS

The Pope needs a secretary. You have been chosen. Welcome to the Vatican.

HolyOS is a narrative puzzle game set entirely within HolyOS, the Church's bespoke operating system, running on hardware that predates few of its users. As Father Lorenzo, newly appointed to serve His Holiness himself, you will spend your days doing what all great bureaucracies demand: reading emails, managing calendars, filtering the pleas of desperate faithful, and keeping the wheels of the world's oldest institution turning.

But the Vatican has secrets. And you are about to find them.

Features:

  • Navigate HolyOS, the Vatican's aging in-house operating system, complete with its own apps and file explorer
  • Chat and exchange emails with cardinals, confidants, and His Holiness himself
  • Filter through the daily flood of letters from ordinary disciples seeking guidance, mercy, or miracles
  • Manage the Pope's schedule and stay on top of your growing to-do list
  • Hunt for hidden, encrypted, sometimes scandalous archives
  • Earn funds and upgrade your operating system
