Firewatch is a game from Campo Santo, available on the Nintendo Switch. The game is set in 1989 in the US state of Wyoming.
Firewatch's website has clearly taken inspiration from the game. A life-size illustration is the main focus of the website.
The illustration features autumnal colors yellow, orange, and brown which are used throughout the entire website.
A little lower on the page is the trailer to see, which also shows the gameplay.
Details, such as the parallax effect in the header and icons designed as merit badges, further complete the picture.
