Yeah, I would definitely let a guy put a kettle over a head and then not do anything as I proceed to listen to my sister get slaughtered.
WELL until they can create AI that can detect when something is on their head in a game like this then it is fine by me seeing as you put a bucket on your head and you wont see them. Also, don't bring up dead rising with the lego man heads as that was designed to do that and the kettles, buckets, baskets, etc weren't.
