*NB this game requires a good plug-in mic (laptop mics work ok... but can be a little flaky with noisy fans!)*

Unknown Number tells the story of a high-stakes heist, and is experienced entirely through a series of interactive “phone calls”. This adventure will have you cracking passwords, tricking guards, impersonating oil executives - and just generally saving the whole goddamn world - all with your voice.


Talk, Sing, Whisper, and Shout your way through this immersive puzzle-adventure that uses voice commands for just about everything.

Use your voice to...

  • NAVIGATE a maze-like oil rig under time pressure
  • DECODE cryptic puzzles to unlock treasure vaults
  • MANIPULATE henchman into abandoning their guard posts
  • PLEDGE your allegiance to a creepy underground eco-movement
  • IMPERSONATE high-profiled oil execs on conference calls
  • MAKE big moral decisions that impact the story
  • TELL knock-knock jokes… and maybe even SAVE the world


Unknown Number starts with a mysterious voicemail from two panicked eco-warriors on an abandoned oil rig. They’re trying to steal $7 billion from the world’s most notorious oil baron, to use in the fight against climate change. But something’s gone terribly wrong – and that’s where you come in.


As the narrative unfolds, you’ll be using voice-commands to talk directly to a rich cast of complex characters - and to solve a wide variety of puzzles. Expect moral quagmires and head-scratching aplenty. Who knows, you might even make it out alive…

Will you answer the call?
