@Zucas: lol you can just kick the lock twice--much faster than knife or shooting.
The only time I got scared was the first time I was playing and Mr. Chainsaw got me from behing--I was looking out for him, too, but I didn't hear him break in downstairs.
Actually, that's a lie--I also jumped on the military base when the flaming guy jumps out of the fridge at you--the only time they really even tried to scare you.
