This one?
I hated him. One of the chapters have you making your way through a bed-maze, with him bursting through every single wall and ceiling vent there is. I once moved a bed to see him waiting for me on the other side, and I hit my Xbox power button in an instance. Shame that I had to start that chapter again after that

Spider Splicers? They weren't
that scary lol. The only games that almost painted my pants a brown, lumpy colour were either Dead Space or WaW's Shi No Numa Zombie map (a lot of ambushes there).
I think, to say the least, I'm scared of the game scenes where it's near pitch-black and you don't know what the hell'll happen next. And veering away from game-fears, SAW has managed to freak me out, not because of the traps, nor the storyline, nor the jumps, but Pigface, she/he always appears out of nowhere and it gives me the fear that they're waiting for me somewhere

It's waiting for you...
