Classified device · Temporal investigation
PragueEcho turns your phone into an Echo — a device that reads the echoes of the past written into the streets of Prague. Head into the city, sync the device with reality, and crack a case that played out long before you arrived.

Premise · What it actually is
Echo is a classified device for temporal investigation. It detects resonances left behind by events across time and reconstructs echoes of the past from them. You become the investigator — and Prague becomes your case.
You catch the sounds of the street as they rang out centuries ago — right where you're standing.
In the right place, a long-forgotten scene opens up right in front of you.
You find the spots where the boundary of time thins out — and something doesn't add up.
Process · How it works
This isn't a guided walk. It's an investigation — you lead it, step by step, right in the streets.
Echo picks up a trace written into the city's resonances. The case begins.
No tourist map. The atmosphere and the device guide you to a real location in the city.
You stand in the right spot, aim, tune in — and the past opens up. You decipher, gather clues, go deeper.
Every clue you crack unlocks the next. You can't skip to the end — you have to truly understand it.
Echo's capabilities · What it can do
No technical specs. Just what you'll actually experience through the Echo.
Audio fragments of the past that play out right on the spot.
Windows into bygone scenes through your phone's camera and sensors.
Uncover what once stood here — and what has since vanished.
Find the places where the boundary of time grows dangerously thin.
Objects that carry resonance and push the case forward.
Every clue is recorded and woven into the broader story.

First series · Defenestration
Defenestration is the first PragueEcho series — three interconnected cases in the streets of New Town. You can play the two base episodes in any order. Finish one of them and you unlock the finale, where all the clues converge at the windows of New Town Hall.
Two episodes → finale. The series finale unlocks a deciphering artefact you receive at the end of a base episode.
Case 1 · Base episode
№ 1419-01Prague 1419 · New Town
A warning that never arrived.
A frightened man flees through a narrow lane in New Town and drops a sealed letter mid-run. Six hundred years later you can only make out a fragment of its echo. Track down who the letter was meant for — and find out if there's still time to stop what's coming.
Case 2 · Base episode
№ 1419-02Prague 1419 · New Town
You saved a stranger. You have no idea why it matters.
In a narrow alley you unknowingly save an unknown man — all he leaves behind is an open journal. Four patients, one mystery, and time running short. Uncover the true cause before the sickness takes the whole city.
