The PC version of Firewatch has a special feature that the console version lacks. You find a disposable camera in the forest. You can use that camera to take pictures in the game as you play. Once you finish the game, you’ll get a link in the menu to a web store where you can buy your prints.
Really, you can get the pictures you took in the game developed. Here are mine.
This is great! Unfortunately only in the PC version of the game.
