Great graphics, creepy story and a lot of blood... that's my kind of game!
I think that the levels are a little bit smalls but it help you to follow the story just straight forward.
Another good thing is the sound. The game start to play some music (very good music indeed) when you are trap or in a middle of a confrontation and the combination between music/sound really put yourself in the game... it means in the middle of hell.
I read other review where the people feels uncomfortable with the movies and a few "talking" scenes but i thing that these parts help the story to be more consistent.
Another good thing is the loading time. The game just stop for a couple of seconds between one level to another so you don't loose the track in this moment and you can read some interesting things to understand a little bit more the story.
