Unrealistically atmospheric and relaxing game

It's not just a shooter... Music, locations, sounds of nature are the main features of this game.  Shooting, animations, are nice. Graphics are great. Control in the game is not very convenient, there is no customization. I don't regret wasting my time on this game.

Played on high graphics

P.s. It's not my native language, so I apologize in advance :)
