Terminal Lucidity

Terminal Lucidity is a single-player psychological thriller in which a lone technician is sent deep underground to perform routine maintenance on a network of supercomputers. You run scripts and try to complete the job, while uncovering the truth behind the machines.

Learn the terminals

The game combines atmospheric horror with cipher-breaking puzzles. Each terminal has its own hidden rules, which you must learn to understand its language. You then work out how those rules combine to produce new outputs.

A self-contained experience

The game is designed to reach an ending in a single 2-to-4-hour sitting. Its map is modelled corner by corner, and its puzzles are handcrafted. Every answer and command is available from the beginning, but you must rediscover them using your own notes and memory. There is no saving and no way out.
