Buy it for the story, not for the gameplay. The game is full of bugs, from not being able to open supply caches to achievements not registering. But I gotta say, the story grabs you from the first few minutes. It turns into almost like a horror game at some point where the story has a lot of twists and turns. The achievements are not all "play and you'll get them" but you need to actually seek them out, which is frustrating.
BTW you can get the turtle even later in the game so don't fret about that. I didn't save the Turt Reynolds because it was bugged.

Short but sweet. Firewatch packs a lot of emotional depth into its five or so hours of playtime, and the art style and overall ambiance are enjoyable. Prepare for some melancholy; this isn't a lighthearted story (though it's not overly dark either).

Though it's an enjoyable experience, this game packs only an afternoon's breadth of content and has nothing in the way of replayability. Buy it on sale.

Great atmosphere, interesting story, its like a 6 hr movie.
