One of the things I found creepy about the game was the fact that when my Malkavian walked around while Obfuscated, I could hear voices whispering from just beyond the veil... Wasn't really
scary, but it did run a tingle down my spine.
Whenever you're hearing whispers in the game when you're supposed to be alone... that always kinda creeped me out.
I can draw zombies pretty well, too, by the way, and there
is something inherently scary about them, but the fact that I didn't even need to shoot 'em in the head to kill them took out some of the fun. Especially when I had killed them all once, because after that, they'd only ever come into the room one at a time. "Fighting for your life" against one zombie that you can kill with one shot just isn't scary.
