About Alter: Echo
One message. One number. Six people the world erased.
A history teacher discovers his entire life has disappeared overnight. No records. No apartment. No identity. The only thing left in his pocket is a phone with one saved contact.
You.
This is Alter ECHO.
A real-time interactive thriller told entirely through messages. Guide six strangers across the world as they uncover a hidden organization erasing people from existence without leaving a trace.
Search archives. Decode files. Solve puzzles. Make impossible choices under pressure. Every decision changes who survives, what is discovered, and how the story ends.
A journalist finds photographs she was never supposed to take.
An engineer discovers he designed part of the system himself.
A forensic pathologist uncovers deaths hidden for decades.
A student inherits secrets his mother died protecting.
And somewhere behind all of it, someone is watching every message you send.
Because the deeper they dig, the clearer one thing becomes:
You were never supposed to be reachable.
