They attack humans to eat them, that's obvious. And zombies can be produced by anything, whether it be a virus or a parasite. And they are smart, smart enough to work together to attack humans.
umm your wrong their brains are dead am i not right and offcourse they eat them because they are meat. they grow stronger but they do not grow smarter.
You're wrong. If their brains are dead, they simply cannot function because the brain commands your limbs to move. This is why you aim for their head, you kill their brain so they cannot move anymore. Want another lesson about zombies?
tell me how is a virus can be destroyed without the antidote plus are you telling me that my dead grandpa is alive in his graveyard and his body isnt skeleton.
Hmm im assuming that zombies are people who got bitten but escaped~ Otherwise there wouldnt be a brain to splatter~ Of course zombies already defy the normal world so who knows~ Infections may not necessarily mean they died but that theyre just not quite human anymore~
