Zombie

Zombies are hostile mobs that appear in Survival Test, Indev, Infdev, and most probably Zombie Siege. Like other hostile mobs, zombies chase players once the player has been spotted. Their attack deals 3 hearts of damage in normal difficulty. They usually appear in groups of two or more.

Zombies only spawn in dark areas, such as unlit areas on the surface at night, or in unlit caves. Like skeletons, zombies burst into flames if they come into contact with direct sunlight.

Zombies can also climb ladders if they walk against one.

History
In Survival Test as of the September 3, 2009 update, zombies were the fastest mob in the game. The title was lost when Spiders were added to the game. Armored zombies appear randomly along with groups of normal zombies. These zombies are easily distinguishable by their body armor and/or helmets. Their armor does not, however, give them any additional hit points; the difference is purely cosmetic. It was later removed during the Indev update.
