Firewatch is the first video game from Campo Santo, and was created by Jake Rodkin and Sean Vanaman, who were the creative leads on The Walking Dead; Nels Anderson, the lead designer of Mark of the Ninja; and artist Olly Moss.[8] Chris Remo was involved in many aspects of the design, and also composed the score.[9] Development for Firewatch began with a single painting by Moss.[2] Jane Ng, lead environmental artist at Campo Santo, was tasked with translating Moss' work into 3D environments while maintaining his stylized artistic vision.[2] Moss, who had previously been known primarily for his graphic design work, had joined Vanaman and Rodkin to found Campo Santo after spending many years working on the periphery of game development.[10] In creating the painting, Moss emulated National Park Service posters from the New Deal era in both color palette and iconography.[11] The development team went on a camping trip to Yosemite National Park for inspiration for the game,[12] where they visited a lookout tower built with the same design as its video game counterpart.[13] Further inspiration for the game came from Vanaman and Anderson's experiences growing up in rural Wyoming.[13]
