<Unknown_Terminal>

While exploring an abandoned industrial district you stumble across a mysterious, faceless building.  Inside, among rusty shelving and forgotten folders, you find a dusty office.  In the middle of the room sits an old IBM PS/2 computer that is still on.  Its phosphor‑green screen blinks like a heartbeat from another era and the analog modem emits a periodic beep – someone or something seems to be waiting for input.

You have uncovered a portal to a digital past that was never meant to be reopened.  Access the old terminal, explore its file system and interact with a text‑based interface reminiscent of DOS.  Navigate corrupted files, decipher encrypted logs, access forbidden programs and uncover who — or what — was behind that screen.  Every command you type reveals fragments of a buried story, one clue after another.  A retro‑digital investigation where the only interface is you… and the truth lies hidden in a prompt that was never supposed to respond again.

Authors’ note: This is a tiny personal project we put together over a weekend using Python. It doesn’t aim to be anything fancy—it’s short, free, and we simply hope you'll have fun playing it.
