Holy crap! The zombies are actually scary! Making them run fast is a good choice because it gives people less time to think about what to do and that rushed feeling is frightening

The earliest comment is 29 minutes ago, still, this video has great animations, Build-up isnt too long. character's react like real people, and reveals are good
