Armors

Armor are types of clothing that give the player bonuses.

SAS: Zombie Assault 3
In, bonuses include increased defense, increased movement, decreased respawn time when killed, increased accuracy, or even increased health. All new players will start off with Basic armor which only provide enough stats to survive a few Ranks, but with them being weak they should be replaced with better armor within Ranks 6-14.

Types of Armor
There are three kinds of armor: the uncategorized armor of the 'Basic' set, Tactical Armor, and Heavy Armor.

The Basic Helmet and Gloves improve Defense, Health, and Accuracy; the Basic Vest improves Defense, Health, and Respawn; the Basic Boots improve Health, Speed, and Respawn.

Tactical Helmets and Gloves improve Defense, Respawn, and Accuracy; Tactical Vests and Pants improve Defense, Health, and Accuracy; Tactical Boots improve Defense, Health, and Speed.

Heavy Helmets, Vests, Pants, and Gloves improve Defense, Health, and Respawn; Heavy Boots improve Defense, Speed, and Respawn.

SAS: Zombie Assault 4
In, armors are made by various industries and come in many sets. They can give the player bonuses of physical resistance, toxic resistance, heat resistance, increased or decreased movement speed, damage to zombies' melee attacks, weapon damage, and reload speed. By augmenting the armor (as can be done with weapons), the armor can give: see Augments for more information.
 * Additional physical protection
 * Additional heat protection
 * Additional toxic protection
 * Increased critical chance
 * Increased gun damage
 * Increased maximum health
 * Increased maximum energy
 * Decreased recovery time
 * Decreased reload speed
 * Increased health regeneration rate
 * Increased energy regeneration rate
 * Increased movement speed
 * Increased damage to melee attackers

In SAS 4, each piece of armor has varying levels of resistances indicated by a number. To calculate the damage reduction, by percentage, from armor and for each damage type, take the square root of the sum of all the numbers of one resistance type and round up. For instance, having a total physical defense of 1,000 yields a 32% damage reduction from all physical attacks, and having a total toxic defense of 350 gives a 19% damage reduction to all chemical attacks.
