Megaarmor

The megaarmor (known as combat armor in the manuals) is an item that appears in the Doom games as a blue military vest. When collected, it increases the player's armor percentage to 200. It cannot be collected if the player already has 200 percent armor. When a megaarmor is obtained, the game displays a HUD message; picked up the megaarmor.

The megaarmor will absorb one half (1/2) of all damage received, rounded down, until it is fully depleted. If a player that had last picked up a megaarmor is damaged to less than 100 percent armor picks up an armor, the megaarmor is replaced by the weaker armor (which absorbs less damage per hit). Because of this, it is sometimes wise to avoid picking up green armor. If the player picks up an armor bonus, however, the protection of the megaarmor will remain.

This item is not counted in the items percentage displayed at the end of each level.
