“The craziest wrong number story ever!”
The SML Podcast

“We've all received a call intended for someone else that somehow made its way to our phone instead. Usually it's kind of a pain, but what if one not only turned out to be a happy accident but actually helped to save the world? In Unknown Number, one misdialed call is all it takes to plunge you into the deep waters of environmental activism, battling big oil and dodging the police.”
Adventure Gamers

“I don't generally post trailers unless they give me that "oh wow, that's cool" feeling. I want to give space to this unusual little treat. Count me in.”
How Games Are Changing The World - Colin Campbell

About This Game

A voice-controlled thriller... told through a series of interactive phone calls

Answer the call from Amanda and Ethan - two eco-warriors conducting a daring heist on an abandoned oil rig... who badly need your help.

Talk, sing, whisper, and shout your way through an immersive puzzle-adventure that uses voice commands for just about everything.

Use your voice to...

  • SOLVE complex puzzles to unlock treasure vaults
  • NAVIGATE a maze-like oil rig under serious time pressure
  • SWEAR into an underground eco-movement run by kids
  • TRICK henchman into abandoning their guard posts
  • IMPERSONATE tyrannical oil execs on high-level conference calls
  • MAKE big moral decisions that impact the story
  • TELL knock-knock jokes… and maybe even SAVE the world

'Unknown Number' is a blockbuster for your ears (and vocal cords!) featuring a full cast of professional voice actors. And of course - like any great heist movie - the plot has more twists and turns than an offshore oil drill.

Will you answer the call?
