Summary: When you think about it ther's not actually that many great, true Survival-horror games available on PS3. This, with it's creepy, tense atmosphere and well balanced stealth/action gameplay is certainly one of the better ones. I have to mention the sight jacking, where you can see through the zombies (and other humans) eyes, as one of the best gameplay innovations i've seen for a while.
Summary: This game is the best true horror game I've played. It recognises the fact that if put in that sort of situation, your first instinct would be survival. Not the lets get a gun and blow everything away type of survival, but the kind where most of the time you run like Hell, or you're forced to hide for your life. You are encouraged to sneak past the Shibito rather than take them out.
