About this game
“Remain on the line. Your presence confirms consent.”
The Interval Bureau: Extension 0 is a short psychological horror game played entirely through a workplace hotline.
You are an employee of the Interval Bureau. You’ve forgotten your employee ID, and you need to recover it.
Call the Bureau. Navigate its extensions. Follow instructions. What begins as a routine administrative problem gradually leads somewhere much stranger.
There are no jump scares. The horror is in the language, the procedures, and what happens when you keep following them.
Around 1 hour, designed to be played in one sitting.
Fully voiced, with original hold music and ambient sound. Headphones recommended.
