About this game

“Remain on the line. Your presence confirms consent.”

The Interval Bureau: Extension 0 is a short, choice driven psychological horror game about corporate dread and identity, played entirely through a workplace hotline.

No jump scares. Just language, policies, and the growing feeling that this call isn’t what it says it is.

  • Length. Around 1 hour, meant to be played in one sitting.

  • How you play. You press digits on a phone keypad and listen to what answers back.

  • Routes. Different numbers send you to different departments, detours, and voices.

  • Audio first. Fully voiced, with hold music and ambience. Headphones recommended for the best experience.

  • Tone. Corporate / administrative horror.
