Firewatch turned up pretty much out of nowhere last March. It looked like an intriguing narrative experience come to life with beautiful art direction. Since then, things have been pretty quiet game.
Until today. Campo Santo have released the first 17 minutes of the title to the internet as part of IGN First. It really does look like a compelling adventure and the art style is pretty enchanting. I really can't wait to explore this story more.
Here is the opening of the game. It shows off the location and dialogue choices that will be available to you. I liked the Toto bit.
