Armored Zombies

Armored Zombies are an enemy in the Zombies mode. They are first encountered at round 20.

Overview
Armored Zombies are equipped with a vest and a helmet that protects them from damage. They have double the health of normal zombies and have 50 armor points that must be depleted to deal damage to them. Their armor level steadily increases with higher rounds, with them gaining 25 more armor points every 15 more rounds with a maximum of 100 armor points.

They are dangerous in large groups like normal zombies and thus must be dispatched of quickly before they overwhelm the player. The most effective weapons against the Armored Zombies are shotguns, machine guns, the RPG-7, and grenades.

Appearance
The Armored Zombies take on several different appearances depending on the map. On the maps Hotel and Prison, they will take on the appearances of zombified U.S Army soldiers and riot officers, respectfully. On the map Townhouse, they take the appearance of Russian Spetsnaz soldiers. On the map Castle, they take the form of Templar knights.

Trivia

 * Sometimes, a bugged Armored Zombie may spawn that ignores barricades, holds an invisible rifle, and instead of attacking the players normally, they simply stand in front of them, and will do no harm to the players. However, if players get close enough, the zombie will melee them with their invisible weapon, downing them in one hit, or two hits with Juggernaut.
 * If the player goes prone in front of an Armored Zombie, they cannot be attacked. However, normal zombies can still target them.
 * Rarely, an Armored Zombie may drop an attachment, which takes the form of the ACOG Sight. Picking it up gives the player a random attachment for their equipped weapon. These attachments are never removed even after upgrading weapons.
