04 / The Unnecessary Lab

Hidden Multiplayer

Multiplayer where you don't expect it.

Proof of concept · APR 9, 2026

A grid of small CRT monitors glowing in the dark.

A second player that does not get a character controller. They get the scenery.

Technical notes

Authority stays with the “main” client
Hidden client sends tiny intents, not a full avatar
If the first player never notices, the experiment still worked
