Doom is scary, cause if oyu play with gamma correction off it's quite dark. then you press a button or enter a certain area and suddenly a door opens behind you but you dont' know untill you hear the horrific sound. then you turn arround thinking it's maybe one or two beast waiting for oyu there but you quickly find out there is a whole bunch of them.

Hexen does it similar, only in Hexen there are more ambient sounds, there is the mist and quick smashing maschines. i remember there is one level where you press a button to open the doors. offcourse you then turn arround and step towrads the open door when suddenly your character goes aaaaaaaaaaaaaaaaaaargh while he is falling in the chasm. it scared me. ok so i loaded, jumped the chasm. but wait i see a powerup on a bed. i think "cool" and step on the bed. a quick SMASH! and i am splashed under the roof that came down on me.

there are also some creepy parts, like those ghosts comming out of the grave or when you walk and then suddenly got hit by salva of plasma/magic from behind etc.
