False Echo is a submarine cryptography thriller from developer Retro Machine, built around decoding wartime radio traffic and deciding which orders are real. You play a crypto officer aboard a submarine in 1942, stamping each intercepted message as genuine or forged while naval politics close in around you.
Quick answer: A playable demo is live on Steam right now, and the full game is set to launch in Spring 2027. No exact day or time has been confirmed yet.
Release status: demo now, full game Spring 2027
The release sits in a window rather than a fixed date. Retro Machine has committed to a Spring 2027 launch for the complete game, without naming a precise calendar day. A demo covering an early slice of the experience is already available to download and play on Steam.

Who you play and where it is set
You take the role of Aleksej von Groznu, a crypto officer serving the Oxyrressian Naval Command aboard submarine Sub 227 in March 1942. He wears a dark naval uniform with shoulder boards and a peaked officer’s cap, and later appears with a bandage wrapped around his head after the boat takes damage.
The world shifts between pixel-art cutscenes of life at sea and your work at the desk. The submarine surfaces in rough waves, slips under a starry night, threads through icebergs, and dives among underwater rock formations. A War Diary belonging to von Groznu frames the story as a personal record of the patrol.
How the core gameplay works
The screen is split in two. A real-time cutaway of the submarine sits above, and your desk workspace runs below it, holding document folders, daily orders, and the crew roster for Sub 227. Each shift you process the day’s encrypted traffic from the desk.
Incoming codes are transcribed on the Obscura M3, a rotor cipher machine that turns scrambled strings into readable messages. You also slice open sealed confidential documents with a pocket knife to pull out their contents.
From there the work becomes verification. You compare sender IDs, approval codes, and verification strings against the daily orders, checking codes such as SUBHUNT to confirm a message belongs. You also hold signatures and stamps up against reference sheets for the Captain and the Political Officer to catch forged papers. An on-screen reminder is blunt about it: “ALWAYS check and compare signatures!”
Every processed message gets stamped with a mechanical dual-state stamper as either TRUE ECHO or FALSE ECHO. That single judgement, authentic or false, is the decision the whole game turns on.
Shift results and the Action Report
Finishing a shift produces an Action Report that scores your performance. It logs messages sent and handed over, verification messages processed, characters typed, typing mistakes, accuracy, total mission time, and time spent on the Obscura. One sample report for March 17, 1942 records 4 messages sent, 1 typing mistake, 94% accuracy, a mission time of 3:22, and 1:08 on the machine.
Each report is signed off as a sworn record, prepared in two copies, with the officer personally guaranteeing its accuracy and promising to report any discrepancies up the chain of command.
Naval politics, crises, and cover-ups
The desk work is wrapped in pressure from above. State Security orders arrive, the Political Officer interferes, and you are pushed to log events a certain way. A medical memo warns about Retromicin, a stimulant that keeps a person awake for 72 hours with side effects that include vomiting, dizziness, very high blood pressure, and a raised heart rate, with the writer stating they are against its use.
Crisis events break the routine. Red alarm lights flash, a cry for help rings out, and you log a switchboard discharge that kills a sailor. The Political Officer then leaves a note reshaping the record into the official story.
Political Officer. This is the official account now. Do not confuse corridor talk with reality.
Combat sits at the edges of the fiction too. A periscope targeting view lines up a torpedo run against a burning enemy destroyer, and the boat later navigates past naval mines under the final title card. For now the demo is the full way in, with the complete game to follow in Spring 2027.
