Great first-person exploration game.

+ good visuals, using cryengine
+ good sounds and music
+ good art style
+ occasional spookiness
+ the story is being told in pictures/visions which is a good way to present a narrative, gives the player the opportunity to use his/her imagination to figure out what has happened yet it leaves some mystery to it
+ it's not an asset flip and it's not short(can't believe this is an actual + in games now, what has happened to the steam store)

- bad <add something bad here when I find it>

I'm not sure in which category to put how big the areas to explore are, there is no sense of direction and you can get lost in them unless you are paying attention to the placement of everything on the map.
