[[ExactlyWhatItSaysOnTheTin Pretty much what it says]]: A variation of the SelfImposedChallenge where the goal is to win with no damage, or at least no deaths (which is commonly referred to as "Hardcore Mode" and is sometimes directly supported as part of the game's coding). This usually requires a ''lot'' of experience with the game in question, and due to the randomness/unpredictability of many games it can be ''very'' challenging, if not impossible. Virtually impossible in [[RolePlayingGame [=RPGs=]]] (due to RandomEncounters and ScratchDamage), for example, and exceedingly difficult in the higher levels of {{Fighting Game}}s (where ''someone'' is bound to hit you ''once'' with a [[ScratchDamage weak punch]]) and [[FirstPersonShooter First Person Shooters]].

Some NintendoHard games required the player to perform No Damage Runs as a matter of course. This also boils down to making your run entirely of [[FlawlessVictory Flawless Victories]].

Many tool-assisted {{Speedrun}}s are also No Damage Runs, since the player can control the character precisely and manipulate random events in his favor. You'd think it would be "most", but taking damage or even dying actually saves time in many games, thanks to MercyInvincibility and the often-resulting knockback from taking damage which usually ends up being the fastest way to move or respawn points strewn across long travel distances, so they can be used for SequenceBreaking.

A variation common among [[{{Shmup}} Shoot-em-ups]] in particular is the 1CC, or "1 Credit Clear", meaning that the game is completed without continuing (dying is still permissible). Given that Shoot-em-ups will often provide the player with infinite continues, and that each credit has finite lives, most fans agree that to claim to have beaten a shmup requires a No Continue Run. A No Death Run (aka 1LC, "1 Life Clear" or "No Miss Clear"[[note]]"miss" is a sort of Engrish shorthand for "mistakes," not "missed shots" or "missiles"[[/note]]) is even more impressive, especially considering that most Shoot-em-ups have the player as a OneHitPointWonder.

In {{Rhythm Game}}s, hitting successive notes accumulates a [[{{Combos}} combo]]; thus, a No Damage Run of a whole stage is known as a "Full Combo", or FC.

Still another variant, especially used among the ''VideoGame/{{Doom}}'' community, is the "Maximum Minimum Health" run, where the player attempts the level on [[IdiosyncraticDifficultyLevels "Ultra-Violence" or "Nightmare" mode]]. Their score is the lowest health they had at any point in the level, or, if they didn't take any damage, their final health at the end of the level.

If a No Damage Run is too much for you, you can instead strive for a No Death Run or a No Continue Run, or select FinalDeathMode as a difficulty level for an in-game No Death Run. If the goal is to ''deal'' no damage, see PacifistRun.

!!Examples
* In ''[[VideoGame/CastlevaniaOrderOfEcclesia Castlevania: Order of Ecclesia]]'', each boss yields a special [[CosmeticAward Medal]] if defeated without taking any hits, making this a game-encouraged challenge. It's even easier when you get the Death Ring, which boosts your stats absurdly (meaning less hits needed to kill a boss), but kills you if you take even a single hit while it's equipped (which makes retrying easier).[[note]]Taking damage from [[CastFromHitPoints using a certain set of glyphs]] doesn't count as taking a hit, so you can use them all you want without having to worry about the medal or the Death Ring.[[/note]]
* This is part of the reason why the Combat School missions are so damn hard in ''MetalSlug 7'': In order to get the best possible score, you not only have to clear the challenge in the fastest time, but do it without dying once. In a ShootEmUp where your character is a OneHitPointWonder.
* ''VideoGame/BubbleBobble'' games, where the characters are [[OneHitPointWonder One Hit Point Wonders]], impose this in order to view any secrets at all. And the first secret is 20 rounds away.
* ''AceCombat 6'' awards you with the Platinum Ace medal if you go through the story mode and avoid any damage.
* ''LittleBigPlanet'' has the "No Lives Lost" challenge available in all levels, also known as "acing" a level. Get through an entire level without dying once (including use of the Try Again command if you get stuck in a level), and you get some extra [[CollectionSidequest goodies]] at the Scoreboard. Required to get OneHundredPercentCompletion in Story Mode, because completion is measured by how many items you've collected in all levels, and items given by No Lives Lost definitely count. Some levels, like Survival Challenges, are literally impossible to do this, because to finish you MUST die somehow (usually part of the challenge, like collect Score Bubbles while staying out of the [[ExactlyWhatItSaysOnTheTin Horrible Gas]]), but these aren't counted in this; you just have to complete the Survival Challenge levels to add to your completion percentage. Player-made levels have this option, so the creators can give extra gifts to players who are really good at their levels, but these aren't required for 100% completion.
* ''VideoGame/SuperSmashBros. Melee'' requires this of you in Adventure mode to get an unlock. Using Donkey Kong makes it ''slightly'' easier.
** It's also a bonus if you don't take any damage during a stage (or a match). Combining it with PacifistRun gets the [[TrueNeutral Switzerland]] bonus.
* These types of runs are frequently required to unlock NewGamePlus modes in the various installments of the ''Franchise/ResidentEvil'' franchise.
* Required (until one reaches the secret boss, at which point it's lifted) to get each character's second ending in ''BushidoBlade''.
* ''VideoGame/MegaMan9'' and ''VideoGame/MegaMan10'' have separate achievements for doing a run with no continues, no deaths, and no damage. A no death run can actually be easier than most expect by using a lot of items, but good luck doing a no damage run!
* If you don't die any time during ''VideoGame/TheLegendOfZeldaLinksAwakening'' it is revealed that Marin escaped the DreamWorld.
* ''VideoGame/TheLegendOfZeldaTwilightPrincess'' actually requires this for one of its sidequests, carrying an exceptionally fragile barrel across monster-infested Hyrule Field. In addition to the barrel breaking if you so much as look at it funny, it's a TimedMission: wait too long, like, say, killing the monsters, and it cools down to uselessness.
* ''VideoGame/DevilMayCry'' games have traditionally made no damage running part of the requirement for getting some {{Bragging Rights Reward}}s.
** A bonus mission in DMC 3 requires you to defeat a patch of enemies untouched to receive one [[HeartContainer blue orb fragment]].
** ''VideoGame/DevilMayCry 3'' had a difficulty based on this, ''Heaven or Hell'' where both the [[OneHitPointWonder player and the enemies die in one hit]]. DMC 4 had ''two'', the aforementioned difficulty from 3, and ''Hell and Hell'' where [[NintendoHard you die in one hit,]] but the enemies don't [[UpToEleven and are based on the hardest "normal" difficulty]].
* Required to beat ''VideoGame/IWannaBeTheGuy'' on the highest difficulty, since you're a OneHitPointWonder and can't save your game. You will not want to try this, as [[BadassBoast only TWO people have EVER finished it on that difficulty.]] [[VideoGame/IWannaBeTheFangame One of them went on to make a fan sequel.]]
* Similar to ''[[VideoGame/IWannaBeTheGuy IWBtG]]'', only much less difficult, is ''RocketKnightAdventures''' Hard mode. The default difficulty is Easy, by the way.
* ''VideoGame/SuperMarioGalaxy'' had "Daredevil Comets", requiring you to complete one of the level's challenges (often a BossBattle) as a OneHitPointWonder. The game's ThatOneBoss, [[http://www.youtube.com/watch?v=-OLZL1r3w3U Bouldergeist]], and the Daredevil run through [[LethalLavaLand Melty Molten Galaxy]] deserve [[http://www.youtube.com/watch?v=OisJWfVn_C0 special mention]].
** VideoGame/SuperMarioGalaxy2 brings the Daredevil Comets back, and then takes it UpToEleven with the very last star, a challenge called [[http://www.youtube.com/watch?v=745zKLijKg8 The Perfect Run]].
* One of the bosses in ''VideoGame/CaveStory'' gives you a CosmeticAward when killing it with no damage taken. Of course, no damage runs are fairly common in that game.
** Especially in the Wii version's "Hard" mode which removes all {{Heart Container}}s from the game, against enemies that do increasing amounts of damage.
* To get the 'I Will Survive' trophy/achievement for ''VideoGame/TeenageMutantNinjaTurtlesTurtlesInTime Re-Shelled'', you are required to play "survival mode" where you only have one life to get through all eight levels of the game.
* Several VideoGame/{{LEGO Adaptation Game}}s have this. There's an achievement for doing this in one level of ''LegoIndianaJones'', and achievements for EVERY level in ''Lego StarWars II'': The Original Trilogy.
* ''{{Painkiller}}'' has this as an optional card condition for Orphanage, the first level in the expansion pack ''Battle Out of Hell''.
* Both ''VideoGame/CrystalCaves'' and ''Videogame/SecretAgent'' give you a lot of bonus points at the end of level for performing these.
* The Papillion suit in ''[[{{PN03}} P.N.03]]'' turns Vanessa into a OneHitpointWonder - completing the game while wearing this means never taking a single hit.
* In ''VideoGame/FableI'', you can take optional boasts during quests (which gives extra Renown if you succeed in completing the boast), one of which is taking no damage. It's incredibly easy to pull this off once you get the [[GameBreaker game-breaking]] Mana Shield spell, since taking a hit with the shield on doesn't count.
* It is possible in some ''HogsOfWar'' missions, and you even get a nice medal for it, however, in the course of the single player game any pig that dies in more than two invidual battles is KilledOffForReal. It's nigh impossible to finish the entire game without losing at least a few good pigs.
* Subverted in ''VideoGame/InTheHunt'', if you got to the final form of the FinalBoss one one credit, you'll get the special DownerEnding where you submarine ''doesn't'' escape the exploding enemy headquarters (after beating said boss). If you want the good ending, you'll have to [[DoWellButNotPerfect see the continue screen at least once]].
* In order to reach the true ending of ''[[SoulSeries Soul Calibur III]]'', the player must complete a No Death Run with at most ''one'' ring out.
* Completing ''VideoGame/{{Ketsui}}'' with no lives lost, AND no bombs used, AND at least 120 million points, grants you access to a harder version of the second loop.
** Similarly, ''VideoGame/MushihimeSama Futari Black Label'' has a TrueFinalBoss that can only be challenged by completing the entire game on God Mode (no, not ''that'' GodMode) up to that point on a single life.
* ''MadWorld'' has [[BraggingRightsReward level challenges]] which require this.
* Required in ''[[VideoGame/MeatBoy Super Meat Boy]]'' for a series of achievements titled "Iron Boy" runs, which require you to complete an entire world without dying. The achievements start out relatively easy with the first few worlds, but eventually get harder, going all the way up to Impossible Boy, which requires you to beat [[BrutalBonusLevel the Cotton Alley Dark World]] without dying, which is somewhat of an inhuman feat, considering the game's difficulty. Only 0.1% percent of all Steam users who have the game also have this achievement, and a good majority of them are cheaters.
** Although, depending on the world that is being played, the game will let players use alternate characters (with the exceptions of [[VideoGame/{{Minecraft}} Steve?]] and Meat Ninja) for the run, and let players play levels out of order, so it's more flexible with this trope than other games.
** VideoGame/TheBindingOfIsaac also has achievements for it, and you get a notification in-game in the form of an unlock. They also have "Boy" titles: Basement (Basement/Cellar floors with no damage), Spelunker (Caves), Darkness (Depths/Necropolis), and [[spoiler: Momma's (Womb/Utero)]] Boy for each chapter. Darkness is currently the hardest to get. It's practically game-imposed with Judas, Samson, and [[spoiler:???]]: the first two only have one heart to start, the last one has no natural health and must live off rarer heart drops that always stack but never refill, meaning that during a run of bad drops you can take very few hits.
* ''BitTrip'' games reward the player with a flashing rainbow PERFECT! on the high scores table for not missing a single beat or other collectible (later games add the requirement of not getting hit by specific projectiles). The difficulty of such a run depends on the game, but they are notoriously difficult, enough that [[http://commandervideo.com/perfects.html the official site recognizes anyone who manages to accomplish such a feat.]]
* In the very first ''SuperMonkeyBall'', beating all 70 stages of Expert, Expert Extra, and Master in a single no-death no-warp run would actually be acknowledged by the game with a special message during the credits (which varied depending on which monkey you chose to play as). In addition, the Play Point values were set up so that such a feat would net you exactly 9,999 Play Points; die once or use a single warp to skip a level and you'll end up with less.
* Beating ''VideoGame/{{VVVVVV}}'' unlocks a No Death Mode, which challenges you to play through as much of the game as you can on a single life, much like the Impossible difficulty in ''VideoGame/IWannaBeTheGuy'' above. All checkpoints are removed, you can't save, [[TheDevTeamThinksOfEverything one room is modified so that]] [[spoiler:you no longer need to die to nab the Shiny Trinket in it]], and dying ends your game and kicks you to a results screen. Successfully completing the entire game in No Death Mode awards you a [[CosmeticAward trophy]].
* In ''VideoGame/KirbyMassAttack'', completing a level or defeating a boss without any Kirby getting hit earns you a gold star. You can't use a mid-level shortcut, however. [[NintendoHard And you have to do this with EVERY level and boss as]] [[HundredPercentCompletion one of the Checklist challenges.]]
** One of the Checklist challenges is to defeat Level 3's boss with only 1 Kirby. Since pretty much every attack KO's a Kirby in one hit, this makes a no damage run a necessity.
* A requirement for most of ''VideoGame/DeadSpace2''[='=]s Hardcore mode; while you still have infinite lives and can take a few hits, dying/continuing places you back at the beginning of the game or your last save (thus undoing '''hours''' of progress), there are no checkpoints [[note]]save for one at the disc change point in the Xbox 360 version; note that it becomes void if you so much as return to the main menu[[/note]], the game is permanently stuck on the hardest difficulty (very strong enemies and few items), everything from your inventory (including upgrades) cannot be carried over through [[NewGamePlus New Game +,]] and you can only save three times over all 15 chapters. And all you get is the same unlock hard mode gets you; [[DudeWheresMyReward another suit with slightly different stats]]. [[spoiler: And a novelty foam finger with "#1" on it for a gun. [[RuleOfFunny And Issac shouts "BANG!" when it's fired.]] [[RuleOfThree And]] it [[LethalJokeItem annihilates enemies]] in a [[OneHitKill single shot]]. ]]
* ''NightStriker'' combines this with PacifistRun. You get a pacifist bonus at the end of a level if you complete it without getting hit, AND not firing any shots. Very hard to pull off, especially in later stages.
* Completing a mission map in ''Dragon Saga''[[note]]the game formerly known as ''Dragonica''[[/note]] without taking any damage earns you the "Fly like a Butterfly" medal, which boosts your maximum HP by 100 points when equipped.
* ''KingdomHearts''. Typically, the sorts of people who do this also import the [[UpdatedRerelease Final Mix]] games, and play them on [[HarderThanHard Critical]]. Blocking is mandatory.
* [[VideoGame/{{X}} X3: Terran Conflict]] has [[AscendedMeme Dead is Dead]] mode where your save is erased when you die. It also has an [[ThatOneAchievement achievement]] for finishing all the quest lines in [=DiD=].
** ''VideoGame/EscapeVelocity'' has Strict Play, which is basically the same minus the achievement.
* Finishing the original NES version of NinjaGaiden is [[NintendoHard already difficult enough as it is.]] Completing it in a single life is widely considered one of the hardest gaming challenges you will ever undertake in your gaming career.
* To obtain the perfect ending in ''Videogame/CrashBandicoot1996'', you have to break all boxes in every stage without dying. This gets [[NintendoHard REALLY]] hard in the [[DifficultySpike later stages]]. This was no longer the case in the sequels.
** Though some levels in the sequels require you to go up ot a certain point without dying to unlock a DeathCourse. Also, [[Videogame/CrashBandicoot3Warped the third game]] introduced the time trials, where there are no Checkpoints but more Aku Aku crates to make up for it.
* Some of the more recent ''Franchise/SonicTheHedgehog'' games have an achievement for this:
** ''VideoGame/SonicGenerations'' has one for beating the final boss without getting hit. In addition, the Challenge act that rewards Modern Sonic's Endless Boost skill requires one, as the skill turns him into a OneHitPointWonder.
** The 2011 port of ''[[VideoGame/SonicTheHedgehogCD Sonic CD]]'' has one for defeating [[EvilKnockoff Metal Sonic]] without getting hit.
** ''VideoGame/SonicTheHedgehog4: Episode I'' has one for beating the E.G.G. Station Zone with no damage.
* Some of the Treasure Hunt challenges on ''VideoGame/KidIcarusUprising'' require beating a specific chapter without taking any damage at all.
* ''VideoGame/JamestownLegendOfTheLostColony'' has an achievement for beating the game in Gauntlet mode without continues, called "[[PunnyName Won! See? See?]]" There are two more achievements for doing so on Divine and Judgement difficulties, and another two for doing it without taking a single hit on those difficulties.
* Some screens in ''VideoGame/BadPiggies'' award you one of the three stars for reaching the finish point with no damage to your vehicle.
* In order to get the "[[McHammer Can't Touch This]]" achievement in ''VideoGame/GatlingGears'', you must complete a level in the final chapter without getting hit at all. Fortunately, it isn't that hard to do in the first stage of the chapter as long as the player is careful.
* VideoGame/RhythmThiefAndTheEmperorsTreasure has Full Contact Challenges for the various songs. A single "Harsh" ranking results in you failing the song.
* ''VideoGame/{{Minecraft}}'' has a Hardcore Mode that ''deletes the entire game world'' if the player dies. Since the entire point of the game is to explore the world and shape it through building ([[CaptainObvious and mining, and crafting]]), this can be a very painful experience if the player has been working on a world for a while, and has grown attached to it. Hardcore Mode also locks the game on the highest difficulty setting, maximizing the amount of damage dealt by monsters, and otherwise making survival as difficult as possible.
** As an extra kick, the game forces you to press the button that irrevocably deletes your world ''yourself,'' rather than doing it automatically upon your death. It simply doesn't give you any other options.
** Hardcore Mode was eventually made available for multiplayer servers in addition to single-player gameplay. In multiplayer, Hardcore Mode means that a player is ''permanently banned'' from the server if they die.
* ''VideoGame/{{Thwaite}}'' has an alternate ending for a No Damage Run, where the culprit is never discovered. [[spoiler:Then the game [[NoFairCheating accuses the player of TASing]].]]
* In some ''WorldOfWarcraft'' quests, there are achievements for completing them without taking any damage, such as a quest in which you must retrieve an item from a collapsing and booby-trapped ruin. These are fairly challenging, but not quite as difficult as some of the examples listed above, since they tend to be shorter and the dangers are telegraphed more (such as a shadow where a rock is about to fall, or a red circle around an enemy area of effect attack).
* Sporcle has [[http://www.sporcle.com/games/subcategory/minefield minefield quizzes]] which expect you to do this: type (or click) a wrong answer and it ends.
* In ''VideoGame/{{Bayonetta}}'', you can only get [[RankInflation Pure Platinum medal]] by scoring lots of combo, finishing the level fast, and most importantly, dodging everything the game throws at you. A ''scratch'' will instantly drop you to a mere Platinum.
* In ''LightNovel/TheLegendaryMoonlightSculptor'', a Virtual Reality MMORPG, the main character is perfectly capable of this because of his relentless training as a martial artist and sword user, and it is in fact necessary in serious battles, as his melee class is a bit of a ''GlassCannon''. However, he often spends most of his time when fighting ordinary battles with little to no HP, dodging and parrying (not an in-game skill) all attacks... because that is the game's condition for raising the endurance stat (the endurance stat reduces incoming damage).
* The "no deaths" version is required in ''VideoGame/Rockman4MinusInfinity'' to fight [[spoiler:Shadow Man]] in Wily Stage 4.
* In ''VideoGame/StreetpassMiiPlaza'''s ''Mii Force'' game, one of goals in each level is beating it without taking a single hit. In order to obtain all the [[Main/HundredPercentCompletion Plaza Tickets]] you need to do this in every stage. Additionally, the unlockable Arcade Mode has a Hard difficulty, where you only have a single weapon, and thus only [[OneHitPointWonder one hit point]] to get through every stage in the game in one run.
* Old Taito arcade game ''Raimais'' allows you to skip levels if you beat all the previous without dying.
* In ''VideoGame/MegaManX5'', the only way to make the Cannon fully destroy Eurasia (thus saving you the trouble of going through the remaining four stages, and also giving you bonus exposition on [[spoiler:the Zero Virus]]) is to complete the first four levels ''and'' the Dynamo battle without using a single continue.
* Much like ''VideoGame/IWannaBeTheGuy''[='=]s Impossible difficulty, ''VideoGame/TheAngryVideoGameNerdAdventures'' has "YOLO" difficulty. The same restrictions apply - in short, this is ''required'' for that mode.
* Not a strict requirement, but if you want to make three stars in any of the combat challenges in ''VideoGame/BatmanArkhamAsylum'' or ''VideoGame/BatmanArkhamCity'', especially the so-called Insane challenges, you really can't take damage. (The game does not specify that you can't, but taking damage resets your combo meter, and you essentially need to be flawless to win most challenges.)
* This is the basis of some of the challenges in ''VideoGame/NESRemix''.
* Some of the challenges in ''VideoGame/NewSuperMarioBrosU'' fit this, as they require the Super Acorn to use - getting hit means losing your gliding/flying powers, and almost immediately the game kills you for it.
* Completing every stage in ''Manga/WanganMidnight Maximum Tune 2'' and its successors without a single defeat grants a few bonuses. First, you get a special title: "Undefeated Winner of the Highway" in ''2'', or "Undefeated Highway Dominator" in ''3''. Second, in ''2'', you get two final tuning blocks instead of one (if you lose, you simply have to finish Story Mode and then drive 5,000 kilometers), and in ''3'' you unlock the ''Wangan Midnight R'' soundtrack.
* The true last challenge in ''VideoGame/{{Something}}''. [[spoiler:Mario has to complete a BossRush, but he has to do it without power ups]].
