A masterpiece! There is nothing else out there like this game. A unique story, great graphics, wonderful music which always starts at the right moment, many fights, interesting puzzles, oh the part in which you have to play based on your senses - what a great idea (based mostly on your hearing, without being able to see much around you!). Headphones are strongly recommended (without it is just not the same). Oh! And the voices that warn you, talk to you, sometimes confuses you which makes it so so so much more interesting! "...sssshhhhhh..... someone else is here..."
I actually found this game by a coincidence, and I felt like I found a treasure. This group of people who created this game is basically telling to all big gaming institutions: "Now, THIS is a great game!" All the other games pale in comparison with Hellblade.
