I just got it for the Xbox 2 days ago, and I have to say.
HOLY FUCKING SHIZZNIPPLES!!!
The first night I played it I was literally sleepless, it's taken me 2 days to get to the first boss due to endless searching around the map for the things I needed to progress.
However, the first boss is actually surprisingly easy.
It's a tense game, pitting you against unearthly, ghastly monsters in pitch black darkness, or in the "Hell" version...
