Firewatch may have one of the shortest and most simple trophy lists of all time. Made up of just five trophies (one bronze, one silver, and three golds), you will get every one on the list by simply completing the game. All five are secret trophies but all you have to do is ‘complete day number #’ The trophies are awarded for competing days 1, 2, 76, 77, and 79. You could unlock all the trophies in two to three hours depending on how thoroughly you explore the map, but Firewatch is such a beautiful game that getting lost is a serious possibility.
