Stuff in Resident Evil Remake and FEAR startled the crap out of me a few times...only works once though, after a time you grow used to scares like that, but the first times are always unexpected... and it's the unexpected that scare me the most...
In Max Payne, one of his Nightmare, you follow a trail of blood in the room of your murdered daughter, the room fades out in a true Poltergeist fashion, and turns into a creepy dark void where you can only walk on the tracks of blood... It's a cryptic maze, and whenever you walk to a dead end, you hear a horrifying cry of Max's daughter... creeped the shit out of me, i nearly had to pass the game, but i've grown used to it now, shit still creeps to my skin though...
In Call of Chulhu - Dark Corners of the Earth (PC Game too) there's some serious whacky shit that creeps the fuck outta me too sometimes...
Honestly, i LOVE anything with horror, movies and games and books, being horrified means they did a good job, and that makes it enjoyable to me...
