About This Game

One terminal still answers.

1985. A connected world goes silent. Factories, utilities, and defense systems have locked out their human operators. You have one surviving maintenance connection—and an order to shut the machine down.

Then the records stop agreeing.

GHOST//ROOT is a keyboard-driven network infiltration thriller in The Lost DOS Games series. Investigate through a monochrome terminal, reconstruct the incident from conflicting evidence, and decide what your authority is worth when the system on the other side begins asking questions of its own.

Read the evidence

Explore 100 network locations across four acts. Work through 24 investigations, compare official records with independent accounts, and preserve discoveries in your evidence journal. Eight casebooks connect clues across the network.

Find your own way through

Recover reusable programs. Decode damaged records, bridge broken routes, and choose what your commands carry into the system. Manage your connection's TRACE as the investigation unfolds.

Decide who to trust

Speak with seven contacts, share evidence, and question their motives—including those of the machine itself. Your decisions lead to six authored endings with consequences reflected in the aftermath.

A terminal you can make your own

  • Keyboard commands, history, contextual completion, and an evidence journal.

  • Adjustable text size and three monochrome themes.

  • Instant text with no flicker, optional interface sounds, and remappable function keys.

  • Manual saves, automatic resume, rotating autosaves, and protected checkpoints.

One connection. A network full of contradictions. Every command has consequences.
