This was probably the most fun I've had playing a horror game in a good while, which surprised me because I really wasn't expecting much out of this one. Jump scares are definitely not the only things that will give you the chills, this game has strong atmosphere, and lurking around to avoid being seen by enemies can be some of the creepiest parts of the game, and can be terrifying when you're being chased.
The game also has enough meat to it to put all of it's mechanics to good use without ever feeling underplayed or gimmicky. I also feel that the game does a good job of making you care about the main character's well being, he goes through so much crap in this game that it makes it all the more motivating to keep going and see what happens next. I wont say more, overall I highly recommend this to horror fans, it's pretty awesome.
