It was night when I arrived at a village. I went to a house with babbies and made some lamps. then, when night fell completely, just a bought a million noises go off. When I walked outside of the house. I saw almost every house in the village being attacked by zombies. They were breaking down doors, and going in and slaughtering the villagers. [including the babbies ] I started trying to kill the zombies, but they just kept coming. In some houses, I would find empty doorways with no people inside. On occasion a villager would flee the house as the zombie was coming in. It was creepy, but I felt it was a nice addition to Minecraft.
Another thing I noticed is that if the door would break down and they managed to escape, they would run into the nearest house until the door was fixed.
