Armor bonus



An armor bonus (or spiritual armor) is a powerup that appears as a gray helmet with a green glow emanating from within. Picking one up increases the player's armor by 1% up to a maximum of 200% (or, in versions of Doom prior to v1.2, a much larger value).

Green security armor and blue combat armor provide different levels of protection (one third and one half of damage, respectively, are absorbed); armor bonuses do not change the type of protection currently in effect. If the player has 0% armor, then picks up one or more armor bonuses, they function as security armor.

Armor bonuses are included in the items percentage displayed at the end of each level.
