SWAT 3 - One of the early levels with a guy who kidnapped little girls. (It was the perfect recration of "psycho house" and whilst I was using non-lethal weapons the whole game, I gave him an extra couple of sprays with the pepper spray)
Half Life 2 - Intro levels (Before you even get a weapon watching the combine kicking in doors and the hint of torture was just a great intro to game to make you hate them)
Vampire: The Masquerade - The Haunted House (It's... just... yeaaaahhh...)
Halo: Combat Evolved - Escaping from the Flood the first time (I know everyone else hated it, but damn, did it inspire the panic it was supposed to. I really was running backwards firing wildly with the shotgun. I loved it.)
Psychonauts - The postman crazyman level (Perfect example of the greatness of Psychonauts)
EDIT: I really thought I had some ones that nobody else would pick. Turns out I'm not alone on Vampire's Haunted House at least
