Unheard

Here's an excerpt from Unheard's Steam description:

Put on your headphones and step back into the past. Use the voices you hear to return to crime scenes, tracking down each individual involved and solving the cases. But where do the voices come from? Can you trust what you hear? And what's the mysterious thread weaving all of these cases together?

A Unique Case-Solving Experience Discover the truth hidden in the voices from the past.

Step through time as you use our device to eavesdrop on conversations from past crime scenes. Every clue, every move, and every motive will be presented in the form of audio. Rather than controlling any one character, you only need listen to their conversations, following along as the story evolves. Use the information you hear to match names to voices and determine how everything (and everyone) is related. Can you discover the truth?
