In video games, usually in the HUD, this trope is a number that represents your armor's durability, i.e how much damage it can take before it breaks and stops protecting you. Can also be done with shields, whether traditional ones or force field ones. This often appears alongside the Life Meter and/or Hit Points.
Like in Hit Points's case, the armor's capability of protecting you (usually by shaving off some percentage of damage you took) is usually subject to Critical Existence Failure (meaning that it won't suffer any reduction in effectiveness even as it nearly breaks).
Regenerating Shield, Static Health is when the armor/shield can regenerate, like Regenerating Health for Hit Points. Anti-Armor attacks may damage this gauge more than any other attacks would (unlike Armor-Piercing Attack, which would ignore the points or only damage it lightly while dealing direct damage to your HP). Mana Shield is when your Mana Meter temporarily becomes Armor Meter as damage you took instead burns your mana.
Note that a Sub-Trope of this is Single-Use Shield, where a defensive object is treated like a One-Hit Point Wonder, but can take any amount of damage, so long as that damage is dealt as a single hit.
- In Counter-Strike: The amount of armor the player has is a value from 0 to 100, to the right of an armor-related symbol, like a kevlar vest, or a shield. Armor is obtained by purchasing kevlar vests.
- id Software's Doom series lists both the player character's health and his armor. As the armor suffers cumulative damage, the monsters' attack points get apportioned in increasing share against the player character's health percentage.
- In Overwatch, physical armor, (which reduces the damage of incoming firenote ) is represented by yellow ticks on your health bar while shield (which doesn't reduce damage, but can regenerate automatically after a few seconds of not taking damage) is represented as blue. Temporary armour and shields (which aren't healed, and sometimes drain away over time) which some abilities provide are represented by darker ticks.
- Games in the Quake series have an armor gauge of the icon+number variety for the player. This is also true for the FOSS spiritual successors, as well as game mods such as Quake Champions: Doom Edition.
- Command & Conquer: Renegade used a gauge and number for both life (with a hollow gauge filling with green) and armor (with a growing row of shields and the exact armor points number on the last one).
- Unreal Tournament's and Unreal Tournament III's armor indicators are represented in the HUD (UT has it in the top-right corner, while UT3 has it in the bottom-left corner) in two ways: the icon+number variety and a human shape which not only displays the kinds of armor they have but also if the user is carrying the Jump Boots with them. In III, if the user isn't carrying any piece of armor, only the health indicator remains.
- Unreal, Unreal Championship, Unreal Tournament 2003, Unreal Tournament 2004 and Unreal Tournament 4 display armor as an icon-number on the HUD.
- Diablo. When you are hit while wearing armor, there's a chance that your armor's Durability will decrease. When its Durability reaches zero, the armor is destroyed. If you take it to the blacksmith before it's destroyed, he can repair it.
- Honkai Impact 3rd: Some stronger mooks, Elite Mooks, and bosses have shield gauges that will reduce the damage taken and make them resistant to flinching until the gauge is depleted; bosses will also become stunned/dazed when it happens. The shield will eventually regenerate, so you gotta give it your all while they're still vulnerable. Some of your Valkyries' attacks may deal extra damage to the shields, while elemental attacks won't damage the shields and instead deal direct damage to the enemy.
- In Stellaris armor is a stat gained by equiping ships or stations with armor plates. They give an armor score, which in turn gives an armor percentage decided by the ship size (larger ships need more armor points to gain the same armor percentage). Damage is calculated by how much it relatively would harm a ship with the same hitpoints times [1 + armor percentage]. Energy weapons and large kinetic weapons also have the ability to bypass a certain percentage of armor points, reducing their relative armor percentage.
- In Divinity: Original Sin II, each character has two armor meters: Physical and Magical, with each absorbing 1-for-1 the damage from the corresponding attack types. These meters are based on the character's equipment and don't regenerate in combat (without the use of special abilities), while running out of any type allows the character to be targeted by Status Effects (while the armor is up, only certain effects like Necrofire affect the character).
- In Dragon Age: Inquisition, characters of the warrior class get the "Guard" points, which are obtained by using certain abilities and passives and are layered on top of the regular Life Meter, absorbing the brunt of incoming damage before the warrior starts losing HP. With certain Item Crafting tricks, it is possible for rogues and mages to get Guard points, as well, giving them warrior-level defenses in addition to their own DPS, which is as broken as it sounds.
- The Legend of Zelda: Skyward Sword's shields use a meter to indicate how much more damage they can take. The final shield doesn't take damage, but still has a meter.
- In Halo, players play as Spartans who wear armor with in-built energy shielding. The shield drains away as the player takes damage and once it's completely depleted, their HP starts taking hits.
- In Outlaws, you can find boilerplates to use as armour whose durability is shown as a card on the bottom of the screen that slides down with each hit they absorb.
- Quake IV has a regenerating shield gauge for vehicles driven by the player and the bosses.
- The console versions of Unreal Tournament displays armor as a meter gauge.
- Unreal II: The Awakening displays shields as a meter gauge.
- In the StarCraft series, Protoss units and buildings have a blue bar over their HP bar which indicates the current strength of their shields. Once these are depleted, damage is applied directly to their HP, and a visual effect indicates whether a unit/building has shields.
- This is a special ability of certain Imperial Guard units in Dawn of War II. You buy them extra armor, which takes damage before their HP does. This armor can't be repaired, only replaced wholesale by buying it again.
- Alien Shooter: The game lets you acquire armors, ranging from simple kevlar vests all the way to full body armors. They also come with durability points that shows up in a gauge next to your HP bar when you equip them.
- Gungrave: Beyond the Grave (the player character) has a blue bar beneath his HP bar that serves as this; he wouldn't actually be damaged from heavy gunfire of Mooks as long as the bar is still there, but if it depletes, that's when he takes damage normally.
- In Minecraft, shields and each piece of armour have a meter that whittles down as the player takes damage while wearing them, eventually breaking when that meter runs out and leaving player more vulnerable.
- Many games from the Grand Theft Auto series have a meter to represent body armor. In Grand Theft Auto III and Grand Theft Auto: Vice City, this was basically an extension of your life gauge. Starting in Grand Theft Auto: San Andreas, there were attacks which bypassed the armor and dealt damage directly to the character.
