Sunray OS is a mystery-horror game 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.
