i did what another poster above did when it came to the men with bags on their head, i found the video on here
if you can't find the post then have a look on youtube as it's far far easier
i didn't think the idea was all that bad at all, obviously it didn't really flow very well in the game haha but i don't think it was a bad idea!
i also got scared on the mansion level :\ surely i'm not the only one to jump when the zombie reached from the side wall? :s
i must say, as far as having no ammunition goes i didn't really find that a problem at all :\
