How MysteryOS turned an alien operating system into a puzzle game

By Steven Coochin — 13 March 2026

This week marks a slightly unusual milestone for us at Clermont Digital. A game we developed, MysteryOS, is launching on Steam. Here's how enterprise software thinking became a desktop puzzle game.

MysteryOS drops you into operating systems that don't exist. The menus are in languages nobody speaks. The UI follows rules nobody explained. Wrong clicks crash the system, and in hardcore mode, mistakes are permanent. There are no tutorials. You explore, experiment, and slowly piece together how each alien OS works. It's the feeling of opening unfamiliar enterprise software for the first time, turned into a proper puzzle game.

The game features three modes: Explorer (untimed), Standard (with a session timer), and Hardcore (where mistakes are permanent). Players take on missions across file discovery, program execution, and message decoding with unique alien language and UI logic per level.
