All we need is brains

Zombies are sensitive to daylight, so they can only stay underground. The only thing they need to live or to come above ground is human brain. They are real trouble makers as long as they feed with brains and walk outside. All they do is spread terror, annoy and hunt more brains to keep on doing this. You can stop them! Throw them brains as bait, they will come out the second they sniff it, shoot them or throw them into the sea once they come out. Destroy them all; get points, save the people!
