Our take on Sunray OS

The defining detail is that the entire mystery is investigated inside a fictional computer operating system, where websites, applications, videos, and a suspicious chatbot form the main investigative environment.

What is Sunray OS?

Investigate the vanishing of a computer’s former owner through a fictional desktop modeled after familiar operating systems.

Search more than 10 websites, inspect over 10 programs, review videos, play music, alter the desktop, and exchange messages with Zippy, an unsettling chatbot. A linear narrative unfolds through scripted incidents, conversations, required puzzles, and concealed secrets. The investigation asks what became of the previous owner, why Zippy acts abnormally, and what information the operating system keeps hidden.
