The game was directed by Olly Moss and Sean Vanaman, written by Chris Remo, Jake Rodkin, Moss and Vanaman, and produced by Gabe McGill and artist Jane Ng. His exchanges with Delilah inform the process by which their relationship is developed.
Henry interacts with Delilah using a walkie-talkie, with the player choosing from dialog options to communicate. A month after his first day at work, strange things begin happening to him and his supervisor Delilah, which connects to a conspired mystery that happened years ago. The story follows a fire lookout named Henry in the Shoshone National Forest, a year after the Yellowstone fires of 1988. The game was released in February 2016 for Microsoft Windows, OS X, Linux, and PlayStation 4, for Xbox One in September 2016, and for Nintendo Switch in December 2018. Firewatch is an adventure game developed by Campo Santo and published by the developer in partnership with Panic.
