Armor

Armor is a major mechanic in-game, used by all characters in Single Player and Multiplayer, and is changed in Zombies. Armor can be bought and requisitioned (see Requisition Orders) to the player character, or unlocked at higher levels for Multiplayer (absent in Classic Multiplayer modes).

How Armor Works (Regular Mechanics)
Armor in Single Player and Multiplayer negate damage towards the player's health, the health of which can degrade until breaking, exposing the player to harm. Enemies can drop small armor packs to restore your armor by 10 to 20 points. Well-armored enemies can drop up to 5 armor packs, no less than 3.

Armor can be stored for later use. When equipped, it will show up as pieces of 'clothing' over the character in varied amounts. Light Ballistic Vests will be shown under jackets or any clothing equipped over shirts, meaning you can have hidden armor. The appearance of the armor pieces vary from different types of materials and style. An example: A civilian Standard Ballistic Vest looks more smooth than a police vest, and not as plated as military vests.

Armor can also have customized appearances from Missions, DLC Packs, or from Contracts.

Types of Armor
Armor can come in many different types. There is not just armor coverage, but also concealment factors, and the type of armor material.

Zombies Mode Mechanics
In Zombies, it can be bought for 2000 Units, allowing one to have a regenerative armor pool unless it is fully depleted. After completing a certain Easter Egg in any map, one can get Golden Armor, which lasts for more hits and regenerates even from 0. However, you still lose it when you go down, but you can purchase the armor again for 5000 Units.

Upon completing The Complex in Classic and all previous quests, you can enable Aftermath, which allows you to purchase the Golden Armor without needing to complete the Easter Egg.
