All I can say about Outlast is thanks god I'm not nervous enough because this game is truly f*cked up. There are so many scary moments, maniacs who will rip your head off your body. Also there are some psychos who f*cks dead men in a butt (Outlast is the first game ever that includes necrophilia) or the psychos who masturbates on a dead body.
Oh, I forgot about The Groom. He's a maniac who tries to find his perfect bride. That's why he transforms men into women (in an awful way ).
Game is really amazing and genious but I wouldn't recommend it to nervous people because it is really gruesome and scary game.
