Firewatch is the next game to be announced, a game where you play as a man who is in the Wyoming wilderness being led around by a woman on a radio. The game revolves around you following the directions of the woman when things go wrong in the area, but when things start to go REALLY wrong then you have to figure out what you're going to do next.

The game has a light cartoon feel but some parts of the trailer might allude to something else that may be waiting for players.
