Steam News announces that The Vanishing of Ethan Carter is now available on Steam, and GOG.com announces they are now selling the new thriller from The Astronauts as well. Here's what they have to say about the game:

The Vanishing of Ethan Carter is a first-person story-driven mystery game that focuses entirely on exploration and discovery. It contains no combat or explosions of any kind. If our game leaves any scars, we hope you won’t be able to see them.

You play the game as Paul Prospero, an occult-minded detective who receives a disturbing letter from Ethan Carter. Realizing the boy is in grave danger, Paul arrives at Ethan’s home of Red Creek Valley, where things turn out to be even worse than he imagined. Ethan has vanished in the wake of a brutal murder, which Paul quickly discerns might not be the only local murder worth looking into.
