MARA VOSS / ORISON
● SIGNAL ACQUIRED / 00-13-84-NULL
A message from
the wrong time.
A strange pager. A missing technician. Messages crossing a timeline they should never be able to leave.
VERSION 1.1.0 · WINDOWS 64-BIT · OFFLINE · NO TELEMETRY
IF IT KNOWS YOUR NAME, DO NOT ANSWER.
Some messages
were never meant
to arrive.
You find an old pager wrapped in grey antistatic film. It has no recognizable brand, no charging port and only one physical button.
Then it vibrates.
On the other end is Mara Voss, mission specialist aboard the survey vessel Orison. She needs your help. The impossible part is not that she is far away.
It is that her message is decades late.

A found object.
A living signal.
Dead Letter turns branching interactive fiction into the feeling of handling something real — tactile, unreliable and impossible to put down.

Your replies shape trust, reveal different paths and leave consequences that persist.
Listen to the machine
Generated retro audio, vibration, interference and a living LCD make the pager feel physical.

What would
you answer?
Try a fragment of Dead Letter's choice system. Every reply changes what comes back through the noise.
