About the Game

Sunray OS is a mystery-thriller game with horror elements in which you must investigate the disappearance of a guy whose only connection to you is that he was the previous owner of your new computer.

To do this, you will have to interact with a fictional operating system inspired by real systems, using applications, browsing websites, watching videos, or chatting with "Zippy", a chatbot who seems to have something wrong with it.

Sunray OS features a linear but well-detailed storyline, unexpected events, mysteries to solve in order to progress, and hidden secrets.

WILL YOU SOLVE THE MYSTERY?

You just bought a cheap PC online. Suddenly, however, you discover that you are not the first owner of the PC, and the person who owned it before you has seemingly vanished into thin air. Your PC becomes the only real clue to track him down.

A FULLY EXPLORABLE PC

Explore clues by interacting with over 10 highly detailed websites, delve into 10+ applications, and enjoy a fully customizable desktop. Remember to take breaks from the investigation and relax with music and videos.

A RICH AND ENTERTAINING STORY

What happened to the previous owner? Why is this "Zippy" chatbot acting weird? What secrets is this OS hiding? With numerous mysteries to unravel and people to talk to, what will be your first move?
