Armor is a protective health item in Duke Nukem 3D.
Armor gives the player 100 armor points when picked up. In addition, it makes it so that each enemy attack that hits the player is reduced from anywhere between 20% to 50%. The amount that is reduced is instead transferred to the player’s armor points.
A variation of Armor known as Used Armor may be dropped by dead Pig Cops. Used Armor gives the player anywhere from 50 or 75 armor points when picked up.
