Zombie Enemies are a dangerous type of Enemy Unit that appear in Zombie Outbreaks, late Stories of Legend, Island of Ash, Parade of the Dead and Unholy Tempest. Most of them have the following two abilities: They can burrow under your front lines to reach your cats behind the lines, and they can revive once when killed, usually at 50% Health (With the exceptions of Zyclone, Daboo of the Dead and Zamelle, which can revive many, many times). When they get killed again, they die for good.
