Brutal.
It is fantastic.
Presentation: VERY TRIPPY. VERY SCARY. Music, effects, story (its OK) very surreal and chilling.
Graphics: Some parts are bland, some are great. Very good flow.
Sound: Fantastic Voice acting, sounds, music, really adds to the experience.
Gameplay: Something basic in other games is huge here. Melee is so important, whereas gunplay is weak. Kinda like real life. The CSI parts are cool too, lots of variety. Like a friggin bear chase.
Lasting appeal: Weak. No trophies, bad online, except for one mode, no one online, not even much story replayability. Rent it.
Overall, this is IMO the second scariest game ever. Bloody, gruesome, intense. 9.5
