[[caption-width-right:320:This is basically the entire level.]]

->''"I'm ashamed of you, Rock. Teleporting straight to the boss rooms? I thought I had taught you better."''
-->-- '''[[BigBad Dr. Light]]''', ''VideoGame/MegaMansChristmasCarol'' (which is actually a BossGame)

[[ExactlyWhatItSaysOnTheTin A level that consists entirely of a]] BossBattle. Usually, this is done for plot reasons, even in games [[ExcusePlot which don't have much.]] A ClimaxBoss and especially the FinalBoss are more likely to have these.

They may be preceded by a BossCorridor and supply some SuspiciousVideoGameGenerosity. It still follows this trope as long as there isn't any serious danger before the boss.

This trope has become increasingly more common in later platformer games with (slightly) deeper plots.

When taken to extremes this leads to a BossGame, where ''every'' level is a Boss-Only Level. Compare BossBonanza, which is a level devoted to ''several'' bosses. See also BattleshipRaid.

The {{inver|tedTrope}}se of this is MooksButNoBosses.


[[folder:Action Game]]
* Almost all of the bosses in the first ''VideoGame/AmericanMcGeesAlice'' are like this. Only the Red King and [[DualBoss Tweedle Dee and Tweedle Dum]] avert this.
* Mission 6 in ''{{VideoGame/Contra}}: Shattered Soldier'' is entirely a SequentialBoss fight, and Mission 7 is the TrueFinalBoss.
* In the game adaptation of ''VideoGame/OnePiece'' for the GBA, each world is separated into three levels, the third of which being a boss fight with the corresponding ArcVillain.
* The last few levels of ''VideoGame/TheMatrixPathOfNeo'' are these.
* While ''VideoGame/AlienSoldier'' is a BossGame, there are still "levels" (mostly just short walkways between fights). Stage 20, however, is solely occupied by [[SequentialBoss the Seven Force.]]
* The bosses' levels in ''VideoGame/{{Splatoon}}''. As soon as you arrive to one, you're only a few meters apart from the battlefield.
* ''VideoGame/MetalGearSolidV'' has a few: Episodes 11, 29 and 31 [[spoiler: and their Extreme versions]] are nothing but boss battles.

[[folder:Action Adventure]]
* ''VideoGame/EccoTheDolphin'':
** The final level of the original is devoted to the battle with the [[BigBad Vortex Queen]].
** ''Ecco: The Tides of Time'' also has a Vortex Queen level, though it's not the final one.
* In the Playstation ''VideoGame/SpiderMan'' game, the chapter "Rhino's Rampage" consisted solely of a boss fight with Rhino.
* Most (if not all) of ''VideoGame/{{Bomberman}}'s'' boss fights are in Boss-Only Levels.
* ''VideoGame/TheBindingOfIsaac'':
** TheVeryDefinitelyFinalDungeon in the expansion pack has a bossfight in almost every single room, and all except one are against two different bosses. [[NintendoHard How's that for hard?]] The remake brings this level back as well as adding an evil counterpart of it. [[spoiler:After beating either of them, you can make them true Boss Only Levels if you obtain both Key Pieces or Dad's Key, which will grant you access to the game's True Final Boss in the first room.]]
** Emperor cards have the ability to turn any level into a Boss Only Level. Just use it immediately when you enter a level and you skip right to the boss.
** The ''Afterbirth'' expansion introduces a proper Boss Only Level: [[spoiler:The Blue Womb. It contains a core room with four chests, two Item Rooms, one Shop, and a single fighting room. Said fighting room contains Hush, the strongest boss in the game.]]
** Greed Mode in ''Afterbirth'' ends on a Boss-Only Level: Just called "Ultra Greed," the floor is a continuation of the shop that begins in an empty room and has a boss room ahead of it. [[spoiler:Said boss room is a Cat Scare, containing either Monstro, Super Greed, or a number of regular Greeds. The room ''past'' that, however, is the true battle against Ultra Greed.]]
* The last two levels of ''VideoGame/FamilyGuyBackToTheMultiverse'' are this.
* All bosses except Harsh Possessor and Overset Possessor in ''VideoGame/LuigisMansionDarkMoon'' are fought in missions solely devoted to their battles. The mission leading to Harsh Possessor has a long staircase puzzle that takes a while to navigate before reaching the whereabouts of the boss, while the mission leading to Overset Possessor requires Luigi to climb the Clock Tower in order to meet the boss at the top. For the remaining bosses, no demanding effort prior to the battle is required.

[[folder:Beat 'Em Up]]
* ''VideoGame/{{Bayonetta}}'' does this with the Four Cardinal [[VirtueViceCodification Virtues]] (similar to the SevenHeavenlyVirtues...but as angelic monsters), although one of them has a few enemies before the boss fight. This trend carries over to [[VideoGame/{{Bayonetta 2}} its sequel]].
* This often features on final stages in ''Franchise/DevilMayCry''.
** In ''Devil May Cry'' [[spoiler: the proper fight with the final boss - Mundus The Prince of Darkness, occurs in the peniultimate stage which is just the fight. The last stage is mostly running away from the island where the game took place, but just before you get away you have one last match against Mundus which is much more short and easy.]]
** In ''Devil May Cry 2'' [[spoiler: it's a battle against first Argosax the Chaos and then the Despair Embodied for Dante's scenario, and a battle against Possessed Arius/Arius-Argosax for Lucia's scenario.]]
** In ''Devil May Cry 3'' [[spoiler:you fight your brother Vergil for the third and final time, on a shallow river in the bowels of hell.]]
** In ''Devil May Cry 4'' [[spoiler: Nero fights Sanctus Diabolica, the BigBad fully ascended. After that, he then fights the False Savior which is somewhat easier.]]
** In ''Videogame/DMCDevilMayCry'' [[spoiler: you have Vergil as the final boss once again]].
** However, across the games, there are also some non-final bosses who also take up their entire levels with no level-traversal in sight. [[spoiler:Sanctus' first fight in ''4'' and Mundus' Spawn in ''[=DmC=]'']] are some examples.
* ''VideoGame/MetalGearRisingRevengeance'' does this with the fight against [[TheRival "Jetstream" Sam Rodrigues]] which counts as an entire chapter.
* Stage 8 of ''VideoGame/TheSimpsons'' is a boss fight against Smithers and Burns.
* Quite a few of these appear in ''VideoGame/AsurasWrath''. Specifically, the fights against Wyzen, Kalrow and his Fleet, Augus, Olga's fleet, [[spoiler: Wrath Asura]], The final Deus Battle, [[spoiler: the final Gohma Vlitra Battle, The FinalBossPreview battle against Chakravartin, The Final Yasha battle, and finally, the Last Chakravartin battle]].
* ''VideoGame/MadWorld'' has one of these in each of the first four areas, each acting as the final boss/stage of the area: Von Twirlenkiller in Downtown (though there's a brief motorcycle segment leading up to it), Yokozuna in Asiantown, Elise in the Castle, and Martin in Area 66.
* The final boss of ''VideoGame/AbobosBigAdventure'', [[spoiler:[[VideoGame/PunchOut Little Mac]]]], gets his own level in the style of [[spoiler:his home game.]]
* "Technodrome: The Final Shell Shock!" from ''VideoGame/TeenageMutantNinjaTurtlesTurtlesInTime'' is the FinalBoss, Shredder[=/=][[SuperMode Super Shredder.]]
* The FinalBoss of ''VideoGame/DoubleDragonII'' on the NES gets his own stage as well.
* The sixth and final level of ''Black Belt''/''[[Manga/FistOfTheNorthStar Hokuto no Ken]]'' for the UsefulNotes/SegaMasterSystem is just a battle against Wang/Raoh.
* The first ''VideoGame/{{Battletoads}}'' game has the Dark Queen fight taking up the entire last level.
* ''VideoGame/XMenMutantApocalypse'' featured two Boss-Only Levels: Danger room fights against Omega Red and Juggernaut.
* ''VideoGame/MarvelSuperHeroesWarOfTheGems'' Features the Avenger's Base, where you can fight a holographic copy of any of the bosses of the regular stages.
* The fifth and final stage of ''VideoGame/MitsurugiKamuiHikae'' only consists of a boss battle with Misa's possessed friend Suzuka [[spoiler:and the Demon Blade's final form, Magatsu Hino Tsurugi]].

[[folder:Fighting Game]]
* ''VideoGame/SuperSmashBros Brawl'' does this in the Adventure Mode, with "The Ruined Hall" and "Battleship Halberd Bridge". "The Canyon" [[PlayingWithATrope plays with this]], since the level only contains a MultiMookMelee.

[[folder:First Person Shooter]]
* The only opponent in Episode 1 Level 9 of ''VideoGame/Wolfenstein3D'' was the boss, Hans Grosse.
* There are some in the ''VideoGame/MetroidPrimeTrilogy'', namely the Sky Temple in ''VideoGame/MetroidPrime2Echoes'' and the Leviathan Seed regions in ''VideoGame/MetroidPrime3Corruption''. These are a first for the ''Metroid'' series, as the bosses often reside at the end (or central part) of large zones.
* ''VideoGame/{{Doom}}'':
** The endings of episodes 2 and 3, Tower of Babel (a fight against the Cyberdemon) and Dis (Spider Mastermind) from the original ''Doom'', at least on lower difficulties (higher ones add a couple Lost Souls to the former and Cacodemons to the latter).
** ''Doom II'':
*** Icon of Sin (the final level) is technically this, though the [[FanNickname semi-]]eponymous Icon is also a MookMaker and will fill the level with enemies once you start the fight.
*** The second secret level, being a CallBack to the above ''Wolfenstein 3D'' level, is also technically this on lower difficulties (Hurt Me Plenty and above add SS Nazis to the level; there's also the four hanging iterations of ''VideoGame/CommanderKeen'''s eponymous character you have to kill to exit the level, but they're totally harmless).
* The Lair of Chthon from the original ''VideoGame/QuakeI''. No points for guessing what boss you fight in there.
* The Stadium, the last level of episode three in ''VideoGame/DukeNukem3D'' and [[NostalgiaLevel the introduction]] of ''VideoGame/DukeNukemForever'': a duel against the Cycloid Emperor in a football stadium.
--> ''"It's down to you and me, you one-eyed freak!"''
* The N64 version of ''VideoGame/DukeNukem3D'' gives all three of the game's bosses their own levels; the last two rooms in "The Abyss" and "Overlord" levels are separated from the rest of the level; they drop into these rooms and end the stages where you use them.
* The final level in ''VideoGame/BatmanDoom'', featuring a duel against Bane in [[spoiler:the ruins of your Batcave]].
* In ''VideoGame/MegaMan8BitDeathmatch'', all of the single player bosses are fought in "separate" areas in a specially made map. This map, titled ''Unknown'', is unplayable in normal multiplayer and any attempt to play on it will automatically redirect all players to Cut Man's stage.
* ''VideoGame/JudgeDreddDreddVsDeath'': The Smokatorium level is built entirely around defeating Judge Fire, the second boss.

[[folder:Hack And Slash]]
* Exaggerated in ''VideoGame/{{Gauntlet}} Dark Legacy'': each of the realm bosses gets a level to themselves.
* The Rank 10 and 7 stages in ''VideoGame/NoMoreHeroes2DesperateStruggle'', as well as the Henry stage. In the former two, Travis manages to reach the whereabouts of the bosses without needing to go through a path filled with enemies, while the latter one has Henry being trapped within a nightmare because Mimmy won't allow him to wake up (thus forcing the battle as soon as they finish talking).

[[folder:Platform Game]]
* The ''Franchise/SonicTheHedgehog'' series.
** The trend started with [[VideoGame/SonicTheHedgehog1 the first game]] (which has the Final Zone), and ''really'' took off after [[VideoGame/Sonic3AndKnuckles The Doomsday Zone]], with the final bosses of most games take up their own level, usually played [[EleventhHourSuperPower while in]] SuperMode. In addition, the second game's Death Egg Zone was just two boss fights. Exaggerated in pretty much every ''Sonic'' game since ''[[VideoGame/SonicAdventure Adventure]]'', which all give bosses their own levels.
** ''VideoGame/Sonic3DBlast'' gave each boss their own level as well.
** The Wii and [=PS2=] versions of ''VideoGame/SonicUnleashed'' demote Mazuri to one of these, possibly to save space.
** While ''VideoGame/SonicLostWorld'' mostly averts this trope, the Wii U version of Lava Mountain has this in Zones 1 and 4, while the entire level is this in the 3DS version.
** The Game Gear platform games and ''VideoGame/SonicCD'' have the trope in downplayed form; the third acts in these games are boss levels, but contain a very short platforming/pre-fight area prior to the boss. The two exceptions are ''Sonic 1 Game Gear's'' "Scrap Brain Act 3", which is navigating through a maze of hallways with no boss fight, and ''Sonic 2 Game Gear's'' "Green Hills Act 3", where the platforming is bouncing across hills of springs with one-hit kill spikes waiting for Sonic should he fall, plus no checkpoint, making this stage one of the contenders for ThatOneLevel in this game and the ''Sonic'' series in general.
* ACE and Kevin, the only two bosses in ''VideoGame/Gamer2'', are both the only enemies fought in their respective levels.
* ''Franchise/SuperMarioBros'':
** The first World 7 mini-fortress of ''VideoGame/SuperMarioBros3'' is an odd case in that it's a full-sized level, but there's no {{Mook}}s in it, and there are accessories for some enemies but without the relevant enemies attached to them. The only enemy in the entire fortress is [[MiniBoss Boom-Boom]], who shows up at the end as usual.
** The first ''VideoGame/SuperMarioGalaxy'' has Bonefin Galaxy, where the only objective is to defeat Kingfin. There's also the first Bowser Jr. level (located in the Terrace), as once Mario moves on from the first planet, in the next he'll confront Megaleg.
** Boss Blitz Galaxy in ''VideoGame/SuperMarioGalaxy2''. Also a case of BossRush.
** The levels where Hisstocrat, Queen Hisstocrat and Motley Bossblob are fought in ''VideoGame/SuperMario3DWorld''.
** In ''VideoGame/SuperMarioOdyssey'', the [[spoiler:Cloud Kingdom]] and [[spoiler:Ruined Kingdom]] are little more than glorified arenas for the fights against Bowser and [[spoiler:the Ruined Dragon]] (respectively) the first time you go through them. On subsequent visits, however, they do have a small number of Power Moons to be found there.
* ''Franchise/{{Kirby}}'' always does this, with the exception of [[VideoGame/KirbysDreamLand the first game]].
* In general, ''VideoGame/MegaManClassic'' games use this for the very last stages.
** ''VideoGame/MegaMan2'''s final level is short and only leads up to the final battle with the alien [[spoiler:hologram]].
** In ''VideoGame/MegaMan3'', Break Man, and the Wily Machine get stages to their own [[spoiler:as does Gamma]]. Break Man's stage is literally ''one room'' - that being the one you fight him in, of course.
** The ascended fan-game ''VideoGame/StreetFighterXMegaMan'' has two stages like this. [[spoiler:Balrog and M. Bison.]]
* ''VideoGame/MegaManX'':
** In ''VideoGame/MegaManX4'', the [[DuelBoss duel]] against [[HonorBeforeReason Colonel]] is one of these if you're playing as X. (If you're playing as Zero, you get a cutscene instead.)
** In ''VideoGame/MegaManX5'', the battles with Dynamo are this.
* ''VideoGame/EarthwormJim'' has "Snot a Problem".
* Most games in the ''Franchise/CrashBandicoot'' series, spinoffs included, have bosses and levels completely separate from another. Starting with ''VideoGame/CrashTwinsanity'', bosses were generally placed at the end of levels instead of being given their own standalone stages.
* The original ''VideoGame/SpyroTheDragon'' trilogy gives bosses their own levels.
* In the ''VideoGame/WarioLand'' series, the final boss of ''[[VideoGame/WarioLand3 3]]'' has his own level. Every boss in ''[[VideoGame/WarioLand4 4]]'' and ''Shake It!'' has their own level as well.
* In ''VideoGame/WarioWorld'', while there are bosses at the end of actual levels, world bosses are contained in their own level.
* ''Franchise/DonkeyKong'':
** Every single boss in the ''VideoGame/DonkeyKongCountry'' games is in a level all its own, with the sole exception of the final boss of ''VideoGame/DonkeyKongCountryReturns''. In fact, the final boss of the original game isn't even placed in one of the game worlds; his "level" is just a spot on the overall island map, making it a world on its own (the seventh).
** The original ''VideoGame/DonkeyKong94'' did this, which likely set the trend for the series. Every four stages, you face DK in what is usually a dodging the debris kind of level, then the 8th stage is a fight against DK where you have to fight against him with barrels. The last six levels of the game are also this, where DK and DK Jr. try to harm you every stage and take you down, and it finally ends with a fight against DK, and then a final 9th level activates where you face Giga Kong.
** PlayedWith in the first ''VideoGame/MarioVsDonkeyKong'': while clearing the Mini-Mario Levels always leads players to facing Donkey Kong, after the first battle in any given world the Boss Battle itself is freely accessible afterwards, although not going through the MM levels first "punishes" the player with four HitPoints instead of the "usual" six, as it would be the case if all six Mini Marios are rescued. The sequels play it straight as well.
* ''Franchise/{{Castlevania}}''
** In ''VideoGame/{{Castlevania|I}}'' for the NES, stage 12 is a short corridor leading to a BossBattle, and stage 18 is the famous stairs leading up to an antechamber to the FinalBoss room. The UsefulNotes/MSX2 version turns these into considerably longer levels.
** In ''VideoGame/SuperCastlevaniaIV'', the final areas consist of a series of chambers housing nothing more than bosses. Slogra, Gaibon, Death, and finally Dracula must be fought in sequence with no mooks interfering.
** In ''VideoGame/CastlevaniaRondoOfBlood'', Stage 6 is a boss level in which Shaft resurrects the first four bosses from the [[VideoGame/CastlevaniaI original NES game]] (Giant Bat, Medusa, Mummy, Frankenstein's Monster), and then Richter fights Shaft himself.
* The eighth level of ''VideoGame/KidNikiRadicalNinja'' is really the second part of the FinalBoss battle, where he starts running away.
* Exaggerated in ''VideoGame/MischiefMakers'', ''every'' boss has their own stage. ''Mini-bosses'' have their own stages!
* Level 20 of the SNES version of ''VideoGame/PrinceOfPersia1'' is just the FinalBoss.
* The Poseidome, the Industrial Park and the Chum Bucket Lab from ''VideoGame/SpongeBobSquarePantsBattleForBikiniBottom'' are this.
* ''VideoGame/{{Klonoa}} 2: Lunatea's Veil'' has one of these for each of its bosses. ''Door to Phantomile'' has one for the FinalBoss.
* Stage 8 of ''VideoGame/AlisiaDragoon'' is not so much a stage as a showdown with [[TheDragon Ornah]] and [[BigBad Baldour]].
* Every boss level in ''VideoGame/TinyToonAdventuresBustersHiddenTreasure'', with the exception of the first battle against Montana Max in the [[BigBoosHaunt haunted]] [[GangplankGalleon pirate ship level]] is this. These are the only types of levels in the game that cannot be revisited once completed.
* Every boss in ''VideoGame/TheAdventuresOfLomax''. It's downplayed in that there's a short platforming section before the actual boss fight.
* In ''VideoGame/VirtualBoyWarioLand'', stages 4, 8, 12 and 14 are short boss-only stages, and also the only ones to not have a treasure to collect. The map and treasure collection on the save screen make absolutely no secret of these facts.
* In ''VideoGame/ViceProjectDoom'', most {{Boss Battle}}s take place in separately numbered stages, though the FightWoosh used before each suggests that they really just continue the preceding stages.
* ''VideoGame/{{Ristar}}'': Each planet has two regular levels, followed by one of these.
* ''VideoGame/DynamiteHeaddy'': Every act-ending boss after the first has their own scene, and most of the fights against [[TheRival Trouble Bruin]] do as well.
* The final level of the third EpisodicGame of ''VideoGame/CommanderKeen'', as well as the final level in the GaidenGame ''Keen Dreams'', both consist solely of their respective {{Final Boss}}es.
* The last level of ''VideoGame/{{Leander}}'' consists only of the BigBad's BossRoom.
* All of the boss levels are like this in the later ''VideoGame/LittleBigPlanet'' games. The first game, however, only has it for the AdvancingBossOfDoom and the FinalBoss.
* Most of the bosses in ''VideoGame/BioMenace'' have their own level, and the only enemies appear as distractions. The only exception is the Enforcer, who's reached at the end of the last level.
* The eighth level of PC game ''Toys/{{Bionicle}}: The Game'' is just a SequentialBoss fight with Makuta and the Game Boy Advance game ''Bionicle: Matoran Adventures'' transitions to and from each of its boss fights the same way that it transitions between levels.
* In ''VideoGame/VectorMan'', stages 2, 7, 11, and 16 have very short time limits, as all you have to do is defeat the stage boss to proceed.
* At the end of each world in ''VideoGame/{{Bug}}'', there is a "Finale" scene which consists of the world's boss battle and nothing else.

[[folder:Rail Shooter]]
* The "Hard" route makes Venom one of these in ''VideoGame/StarFox64''. You first fight upgraded forms of [[ThePsychoRangers Star Wolf]], then fight [[BigBad Andross]], then [[OneWingedAngel Andross' Brain]]. There's a short series of hallways to and from the battles with Andross, but it's otherwise nothing but boss fights.
* The final stage in ''[[VideoGame/TimeCrisis Time Crisis 5]]'' is one long final battle against [[spoiler: Robert Baxter]].
* File #4 of ''[[VideoGame/VirtuaCop Virtua Cop 2]]'' is simply one final boss battle against [[BigBad Joe Fang]]. In the third game, it's a BossRush.

[[folder:Role Playing Game]]
* In ''VideoGame/FreedomForce'', the last battle against Time Master is just him and his time clones.
* ''VideoGame/DarkCloud'' does this with most of its boss fights. The sequel, ''VideoGame/DarkChronicle'', does the same.
* ''VideoGame/FinalFantasyIX''
** This game features the [[IDontLikeTheSoundOfThatPlace Hill of Despair]], where you fight the final boss, [[GiantSpaceFleaFromNowhere Necron.]]
** Earth Shrine. A turning point in the plot, since [[spoiler:it unlocks the passage to Terra]], but the boss is a blend of GimmickLevel (you fight it with Zidane and ''Quina'', of all characters) and AnticlimaxBoss (unless you've neglected to learn Blue Magic).
* ''VideoGame/FinalFantasyVII'' has the City of the Ancients (not to be confused with the Temple of the Ancients which precedes it in the plot). There are no random battles, just some items and gear to pick up, a massive plot development followed by a Boss fight, and then Disc 1 is finished.
* The ''King's Field'' games have a few of these. One notable example: in the first game near the endgame area there is a place you must fight 5 bosses ''in a row.'' A door will mark the threshold of the area, and when you step through it one of the boss doors will open, leading you into the fight. You can leave between boss fights if you want, but once you cross that threshold you have to ''start over at the beginning with the first boss.'' Only by beating all 5 bosses can you advance to the endgame area.
* A few examples from ''VideoGame/WorldOfWarcraft''
** The Eye of Eternity instance only has the fight with Malygos.
** Trial of the Crusader has five boss encounters and no trash.
** Throne of the Four Winds only has the fights with the Conclave of Wind and Al'Akir.
** Terrace of Endless Spring essentially is this, as there's only two small sets of trash in the area, which means that two out of the four bosses come immediately after the one before them.
** The Arena of Annihilation is a scenario with a series of boss fights.
** Most of the holiday bosses have become this, despite taking place in dungeons (which are typically trivially easy for the maximum-level players fighting the boss), as queuing for a holiday boss results in you and your group being sent to where the fight happens, or given a direct route to the fight.
* ''VideoGame/DarkSouls''
** The Sanctuary Garden in the Artorias of the Abyss DLC, which consists only of the Sanctuary Guardian's boss arena. When you come back later, there are two DegradedBoss Sanctuary Guardians.
** The Demon Ruins comes close to being a boss-only level, as it has three bosses and most of the respawning enemies are also degraded bosses.
** Quelaag's Domain consists of a colossal spider nest linking Blighttown to the aforementioned Demon Ruins. Aside from two Infested Hollows [[spoiler: and Quelaag's [[IllGirl little sister]] (plus attendant)]], there is only the titular [[SpiderPeople Chaos Spider]] and a Bell of Awakening.
* ''VideoGame/DarkSoulsIII's'' final area, the Kiln of the First Flame, is a small map that only consists of the FinalBoss fight against the Soul of Cinder and the First Flame it is guarding.
* A huge chunk of disc 2 of ''VideoGame/{{Xenogears}}'' is narration, boss fight, narration, boss fight, repeat. Occasionally, you'll crawl through a dungeon before said fight. Occasionally.
* In ''VideoGame/NiNoKuni'', the Ghost Ship is just two fights against a mini boss and a boss. Its counterparts, the Glimmering Grotto and the Vault of Tears, are complete dungeons with puzzles to solve and regular enemies to fight.
* Almost every Elder Dragon in the ''VideoGame/MonsterHunter'' series is fought in one of these. Those places are always unavailable otherwise. In the case of the Underwater Ruins in ''Tri Ultimate'', the lair of Ceadeus, it's also the battlefield to fight [[spoiler:Gold Ceadeus]] and [[spoiler:Abyssal Lagiacrus]], both in G Rank. In the event that you fight an Elder Dragon outside of a specialized map (usually the case with Chameleos, Teostra, Kushala Daora and Valphalk, among others), most small monsters will leave the map. Certain extremely powerful regular monsters (Akantor, Ukanlos, Atlal Ka and most Rare Species of other monsters) have each a specialized secluded area as well.
* The final story mission in ''VideoGame/DragonAgeInquisition'' is a fairly small zone consisting of nothing but the FinalBoss fight against [[BigBad Corypheus]]. Considering how [[QuicksandBox large]] levels in this game can be...
* ''{{VideoGame/Undertale}}'' has a few areas which qualify, to varying extents.
** Toriel's house has no one inside except Toriel and the player. This qualifies because Toriel is fought in her basement.
** New Home is a much larger area, with no fights before [[spoiler:Asgore Dreemur]]. There are, however, a number of "fights" where the monsters do not attack; the "fights" are solely there to provide exposition. [[spoiler:This trope is played differently in a True Pacifist run; there, you only fight one boss—Asriel Dreemur—but briefly encounter Asgore before Toriel [[WhatTheHellHero attacks Asgore]], followed by all other monsters, including bosses, briefly appearing. Meanwhile, in a Genocide Run, there are technically two bosses—Sans and Asgore—but the latter is defeated in a cutscene with no player effort.]]
** [[spoiler:After Flowey takes the human souls and becomes Photoshop Flowey, ''[[UpToEleven nothing]]'' exists except Flowey and the player, as Flowey destroyed it all.]]
** In addition, every boss (and many unique monsters) are encountered in rooms without other encounters. Muffet is a notable example, due to both the length of her boss room and the presence of a room before it, clearly associated with her and possessing no random encounters.
* VideoGame/PokemonGoldAndSilver has Jasmine's, Blaine's, and Blue's Gyms, which are notable for having no regular trainers to battle, with only the leaders available to battle. The remakes however, do add trainers to Blaine's and Blue's Gyms.

* Most of ''VideoGame/{{Cuphead}}'' is going from extravagant [[SequentialBoss multi-phase boss fight]] to boss fight. The only exceptions are the Run n' Gun sections, which are mostly just bonus levels to get money.

[[folder:Shoot 'Em Up]]
* Famously, the third level of ''VideoGame/RType'' is essentially one long battle against a giant alien spacecraft.
* ''VideoGame/{{Gundemonium|Series}} Recollection'' and ''Gundeadli Gne'' do this in their final levels.
* Zone M/Titanic Lance in ''VideoGame/{{Darius}} Gaiden''. Special in that Zone M is right in the middle of the game, and Titanic Lance is generally agreed to be harder than most of the final bosses.
* The first ''VideoGame/BangaiO'' game has the duel with [[GoldfishPoopGang Sabu]] in level 26. There are no enemies at all, with the only obstacles being falling block generators.
* Segment 3 Lead and Segment 7 from ''VideoGame/{{Hellsinker}}'' pits you against Sunken Bishop and Rex Cavalier respectivly for almost the entire duration of the stage.
* The final stage of ''VideoGame/SteelSaviour'' has you play what seems to be a level with many "minibosses"... which are revealed to be the FinalBoss's CognizantLimbs. Finally, you fight the main eye at the end.
* A secret stage in ''VideoGame/AbmneshiTheProphecy'' consists of one long fight against the BonusBoss, Sirisai.
* The final stage of the arcade version of ''VideoGame/Area88'' is this, fighting the Project 4 fortress in an orange sky.
* The final stage of ''VideoGame/{{Kamui}}'' consists solely of the boss battle with Xaffiquel.
* ''Kamui''[='=]s prequel ''VideoGame/{{RefleX}}''
** Area 4 pits you against Cancer.
** Area 7 pits you against ZODIAC Virgo.
** Area 8, the final area, starts with a short cutscene followed by taking on ZODIAC Libra [[spoiler:and two KAMUI units]].
* The last stage of ''VideoGame/RayCrisis'' consists solely of the FinalBoss, and if the conditions are met, the TrueFinalBoss.
* [[AnachronicOrder Stages 6 and 1]] of ''VideoGame/RadiantSilvergun'' are entirely occupied by fights against [[spoiler:Xiga and the Stone-like, respectively (though "fight" is a bit of a [[HoldTheLine loose term]] in the case of the latter)]].

[[folder:Simulation Game]]
* The final mission of ''VideoGame/AceCombatZeroTheBelkanWar'' is just one extended SequentialBoss battle that still takes longer to beat than a typical campaign mission.

[[folder:Third Person Shooter]]
* The final mission of ''VideoGame/MetalSlug 3D'' is a BossBonanza of two SNKBoss-Only Levels. There are no ammo refills in the entire two rooms as well.
* The final level of ''VideoGame/KidIcarusUprising'' is a long, multi-stage boss fight. It is also one of the greatest final bosses in all of gaming.
* Most of the boss missions in the first three ''VideoGame/SyphonFilter'' games. The first of these, the Main Subway Line, can be beaten in mere seconds by shooting Mara Aramov [[BoomHeadshot in the head]].

[[folder:Tower Defense]]
* ''Anime/OsomatsuSan: Hesokuri Wars'': Choromatsu's 10th and final stages of his Beta events, aside from standard Hatabous in helicopters, consists entirely of boss versions of the enemies across a long battlefield.
