I am only scared out by the crawling ones. If you just pause for a few seconds and not kill it you'll see what I mean
I was playing zombies with my mates and there was a crawling zombie and 1 off my mates went down on the floor and started crawling backwards like the zombie was crawling towards him and he was crawling back from it, it was hilarious everybody was laughing we left the zombie crawling for ages but we killed eventually.
