The heroic counterpart to enemies TurningRed.

Not only do VideoGames tend to neglect the hindering effect of non-lethal injuries during combat, sometimes the character's HeroicResolve effectively creates an automatic StatusBuff as they approach CriticalExistenceFailure. This gives the player one last chance to dramatically turn the battle around, at the obvious risk of losing the battle entirely should they continue to take hits.

Sometimes this is an ability inherent to the character, other times it is granted through the use (or acquisition) of special items or equipment. In any case, a CriticalStatusBuff triggers automatically when the user's HP decreases to low levels, though whether or not the status boost ''remains'' in effect after the character has been healed varies from game to game.

If the benefits of this status are powerful enough, they can be the key to many a SelfImposedChallenge, especially the LowLevelRun. In low-level games (and similar challenges) in many RPG[=s=], monsters in TheVeryDefinitelyFinalDungeon are often powerful enough to KO a party member in one or two hits anyway, so if the player is already relying more on "Revive" than "Heal" spells, there's little practical difference between whether said character is at full health or not, and a GenreSavvy player may as well [[InvokedTrope exploit this status]] while they can. Also note that maintaining critical status for prolonged time can be difficult if the game refills the player's HP at regular intervals (such as [[AfterCombatRecovery after every fight]]).

SuperTrope to the LimitBreak and DesperationAttack, which are active skills and attacks. Compare ComebackMechanic, which applies specifically to multiplayer. Contrast InjuredVulnerability, where being in a critical condition adds extra weaknesses.

[[folder:Action Adventure]]
* ''Franchise/MetalGear'': Main characters gain a slight defense boost at critical HP. They can also [[RegeneratingHealth regenerate health]] by crouching and resting, but only as long as their HP is critical.
* A pair of magic rings in ''VideoGame/TheLegendOfZeldaOracleGames'' re-enables {{Sword Beam}}s (that normally only work when at full health) when health drops below 2 or 3 hearts.
** ''TheLegendOfZeldaMinishCap'' has a learnable ability that does the same when down to one heart.
* There's an item in ''VideoGame/TheBindingOfIsaac'' that boosts the player's damage output when critically wounded. Eve starts with it, but ??? gets the most benefit if he finds it, since his inability to regenerate health is treated by the game as being permanently in critical condition.
[[/folder]]

[[folder:Fighting]]
* In one FightingGame adaptation of ''WesternAnimation/BeastWars'' ("Beast Wars Transmetals"), the amount of time required to charge a character's LimitBreak decreases as they take damage, allowing an injured character to unleash them more frequently than a healthy opponent.
* One skill in ''SoulCalibur IV'' is "Will power", a passive ability that boosts a character's attack power when low on HP.
* ''VideoGame/SuperSmashBros Brawl'': Lucario's attacks become stronger (and hit more easily) as his damage increases.
* In the ''VideoGame/BlazBlue'' series, after losing enough health your character's heat gauge, which allows them to perform special attacks, will start filling automatically. Though, this also applies to your opponent.
** In ''Chronophantasma'', overdrives last longer the lower on health you are.
[[/folder]]

[[folder:First Person Shooter]]
* ''VideoGame/TeamFortress2'':
** When the Equalizer, an alternate melee weapon (a pickaxe) for the Soldier, was introduced, it boosted the Soldier's attack power ''and'' speed depending on how much his HP was lowered. The Pyromania Update in Spring 2012 reskinned the Equalizer and [[{{Nerf}} limited]] its effects to damage only, while simultaneously introducing a carbon-copy of the original Equalizer called the Escape Plan that sacrificed the attack upgrades for the speed ones. Anyone who owned the Equalizer during the update got the convenience of a free Escape Plan for each Equalizer that they owned.
** One of the Sniper's unlockable melee weapons, the Shahanshah, inflicts double damage if the sniper's HP is below half.
* ''VideoGame/{{Borderlands 2}}'' has various skills that involve increasing certain stats as health lowers. Most notably is Krieg, who has a skill tree more or less focused on this trope. Specifically, he gains various buffs as he takes damage, particularly once his shields are down. He can even gain a few {{Desperation Attack}}s that either let him toss dynamite when his health hits 0 or even transform into a [[GiantMook Badass Psycho]] when triggering his action skill at 1/3 of his health. In addition there are a number of shields that do things like give health regeneration or melee damage whenever they're completely depleted.

[[folder:MMORPG]]
* ''VideoGame/WorldOfWarcraft'': Affliction warlocks get a healing bonus to their LifeDrain when at 25% health or lower; subtlety rogues have Cheat Death, which gives them a LastChanceHitPoint and massively reduces damage taken for three seconds.
** Blood Fury, one of the Orc racial abilities, used to grant more power the lower your health when you used it.
** ''Mists of Pandaria'' introduced several class abilities which activate only when the player is low on health, granting additional stats or health as a final resort.
[[/folder]]

[[folder:RPG]]
* In ''VideoGame/BreathOfFireDragonQuarter'', the "Soul" class of shields features an ability that provides an increasing defense boost as the wearer's HP decreases. There is also "Reversal", a DesperationAttack.
* ''VideoGame/ChronoTrigger'': A variation. [[spoiler:Magus' Doom Scythe]] does more damage when teammates are dead.
* ''Videogame/DarkSouls'' has the Red and Blue Tearstone Rings, which grant their user a whopping 50% increase in damage and defence respectively when their health drops below 20%. The latter is less practical than the former due to the near-complete lack of health, limiting its benefits.
* ''VideoGame/Disgaea2CursedMemories'': Some abilities activate at less than 25% HP, such as the male ninja, which gains such a large evasion bonus that they can become nigh-impossible to hit.
* ''VideoGame/DragonQuestIX'': A handful of abilities work like this, notably a Minstrel buff that "raises evasiveness in a pinch".
* ''VideoGame/{{Fallout 3}}'' and ''VideoGame/FalloutNewVegas'': The "Nerd Rage!" perk maxes out strength and gives a sizable boost to damage resistance when your health is less than 25% of max.
** ''VideoGame/{{Fallout 3}}'' has the Nuclear Anomaly perk, which causes you to [[ActionBomb detonate in a mushroom cloud the instant your health drops below 20]]. The only reason it doesn't count as a DesperationAttack is because it triggers automatically and cannot be controlled, causing you to erupt every ten seconds while your health stays below 20. On the other hand, it also straddles uselessness by the fact that not only it activates when you are about to die anyway, the explosion damages allies, your armor and due to a bug, ''it kills you on Normal difficulty and above''.
** ''VideoGame/FalloutNewVegas'' has the Hot-Blooded trait, which gives you a 10% damage bonus at <50% health, but docks 2 points from your Agility and Perception in this state.
* ''Franchise/FinalFantasy'' has several examples:
** In a few games, some equipment can activate Protect, Shell, or Haste buffs automatically when the user's HP drops to critical levels.
** The Mystic Knight job in ''VideoGame/FinalFantasyV'' has the Barrier passive ability which causes the character to automatically cast Shell on himself when put into critical health.
** In ''VideoGame/FinalFantasyVI'', when a party member's HP is in critical status, there's a high chance that their normal attack will be a special powerful attack instead, which can be enough to destroy enemies to deal a huge chunk of damage to their HP. However, this is so rare that most players have never seen it while playing.
** ''VideoGame/FinalFantasyVII'' has the Final Attack support materia, which casts the linked materia when the character equipping it is killed -- pairing it with the "Revive" or "Phoenix" materia results in an AutoRevive.
** ''VideoGame/FinalFantasyVIII''[='s=] {{Limit Break}}s activate at random, with a greater chance of occuring if their HP is low or if the character is suffering from negative [[StandardStatusEffects status effects.]]
** ''VideoGame/FinalFantasyX'' contains "SOS" equipment that can grant powerful status boosts while your character is below half of their maximum HP. Since some characters have odd-numbered hit point totals and a Phoenix Down revives your character at half health (rounding down), a clever player of the game's more brutal [[SelfImposedChallenge Self Imposed Challenges]] can double a character's speed almost all the time.
** ''VideoGame/FinalFantasyX2'' has the Cat Nip, an accessory found in the BonusDungeon. If you go critical while having it equipped, all your attacks will do 9999 damage. Pair this with the "Trigger Happy" skill, and you get a GameBreaker that can take out even most BonusDungeon Bosses in one hit.
*** The UpdatedRerelease made the accessory also add the Berserk status in order to counteract the GameBreaker aspect.
** ''VideoGame/FinalFantasyXII'' has a set of abilities on its License board to boost the user's Defense, Attack, and/or Magic when their HP reaches critical levels. (Some bosses have these abilities too.) There are also inverse abilities granting Attack or Magic boosts any time the user is at full HP.
** The [[StoneWall "Sentinel" class]] in ''VideoGame/FinalFantasyXIII'' has a passive ability called Deathward, which boosts their status when their HP drops under 25%.
** ''VideoGame/FinalFantasyTactics'' has abilities to grant a character things like Regen, Reraise, or Haste when their HP is critical.
* ''KingdomHearts'':
** "Defender" increases defense at critical HP, "Berserker/Striker" increases attack power, "Damage Control" halves damage taken, and "Grand Slam" boosts critical hit rate.
** ''[[VideoGame/KingdomHearts358DaysOver2 358/2 Days]]'' includes limit breaks. These allow you to enter a superpowered frenzy when you are low on health.
* In ''VideoGame/TheLegendOfDragoon'', Haschel's [[InfinityPlusOneSword most powerful weapon]] (the "Violent Mace") deals more damage the lower his HP is.
* In ''[[VideoGame/LegendOfLegaia Legaia 2: Duel Saga]]'', certain equipment contains abilities that link a character's atack and/or defense powers to their current HP (directly or inversely). "Reverse-HP" and "Reverse-HP Defense", for example, provide greater effects at low HP. Each character also posesses a secret "Mystic Art" technique that can only be performed at less than half HP.
* ''VideoGame/MonsterHunter'' has the "Adrenaline" skill which functions as a stat boost, either defense (+1) or attack (+2), when the player's character's HP drops below a certain point.
* ''PaperMario'' and its sequel ''The Thousand Year Door'': Quite a few badges give these kinds of abilities, such as attack, defense, and evasiveness boosts when Mario is in the "Danger" state (5 HP or less). There is also an NPC in both games who you can pay to increase one stat at the cost of decreasing another. The very popular "[[GameBreaker Danger Mario]]" build involves using this NPC to lower Mario's ''maximum'' HP to 5, making him permanently in the "Danger" state, and then piling on as many of these badges as possible to turn Mario into an invincible powerhouse.
** There are also badges that give even bigger boosts when Mario is in the "Peril" state (1 HP). However you can't lower Mario's maximum HP below 5, so the "Peril Mario" build doesn't see as much use.
* ''Franchise/{{Pokemon}}'' Aside from {{Desperation Attack}}s like "Flail", "Reversal", and "Endeavor" (which inflict more damage at lower HP), several Pokemon species have passive abilities ("Blaze", "Torrent", "Overgrow", etc.) that boost attacks of a particular elemental type when the user is low on HP. There are also Berries that yield automatic status boosts when the user's HP becomes low.
** Inverted in B/W by the ability Defeatist, which lowers your stats when HP is less than half.
* In the ''VideoGame/PokemonRanger'' spinoff series, "latent power" boosts the Styler's [[CallAHitPointASmeerp attack power]]' when low on HP.
* ''VideoGame/SuperRobotWars'' has the pilot skill "Prevail", which increases accuracy, defense and evasion stats as hit points for their respective unit decrease. Every game has it, and so does every pilot (including bosses).
* In ''VideoGame/TheWorldEndsWithYou'', various clothing items feature status boosts that activate at low HP -- the "[[FanNickname Lapin Angelique Suicidal Special]]" combines said clothes with pins that put the user in critical status from the start of battle, ForMassiveDamage.
* In ''VideoGame/{{Bastion}}'', the Werewhiskey tonic raises critical chance to 100% whenever the Kid drops below 33% health. Might as well make the most of it, right?
[[/folder]]

[[folder:Shoot Em Ups]]
* ''Gunnail'' increases your score multiplier in proportion to how much shield points you're missing. Therefore the best way to play for score is to simply wipe out the entirety of your shield meter at the beginning of each stage. However, this triggers a constant CriticalAnnoyance alarm and [[OneHitPointWonder one more hit]] means a GameOver.
[[/folder]]

[[folder:Tabletop Games]]
* The fourth edition of DungeonsAndDragons introduced a large number of effects that start when a character is seriously wounded, adding a "Bloodied" number (half the characters full HP) to character sheets and monster entries to mark when they come into play. In many monster cases powerful non-recharging effects like SplashDamage attacks get 'reloaded' when the monster is Bloodied.
** While more rare, examples exist in third edition as well. [[TheBerserker Barbarians]] can trade their normal Rage ability for "Berserker Strength", gaining bonuses when their hp falls below a certain threshold. The Pain Mastery feat grants the user a Strength bonus based on how much damage they have taken.
** LetsPlay/SomethingAwfulDungeonsAndDragons: Joey has several attacks and abilities that trigger when he becomes bloodied including an aura of fire, extra attacks, and just straight up extra damage die.
* ''TabletopGame/MagicTheGathering'': The "Near-Death Experience" card instantly wins the game, but only if you start your turn with only one life point. The "Avatar of Hope" is a powerful creature that deploys for nearly free if your health is low.
** The ''Dark Ascension'' set has several "Fateful Hour" cards that have improved effects if their user has 5 or less life. For reference, players start at 20 life.
