*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...
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…
