A BossBattle that doesn't play like a BossBattle. There's a boss health bar, and the level finishes when it reaches 0, but the boss isn't the focus of the level, instead acting as a timer for the level, HoldTheLine-style. The hazards of the level instead consist of mooks and terrain hazards.

Related to BattleshipRaid, ColossusClimb, FlunkyBoss, and AnticlimaxBoss, but is distinct from each - a BattleshipRaid or ColossusClimb keeps the focus on the boss, and the things you have to destroy and the parts of the level you have to traverse are generally part of or ejected from the boss, a FlunkyBoss generally keeps to one room, and an AnticlimaxBoss doesn't take up the whole level. There are also the AdvancingBossOfDoom and GetBackHereBoss tropes, where a boss may be chasing you or you may be chasing the boss, respectively, but in those cases, the boss is often a clear goal (most often in the case of the latter) that must either be avoided or found.

!!Examples:

* The level Aerial Combat from ''{{Bugdom}}''. The level is completed by destroying the beehive at its centre, identical to how Queen Bee and King Ant are completed. The beehive cannot actually attack you, however, and the threats in the level consist of flying bees and various terrain hazards on the ground.
* Dr. Zomboss from ''VideoGame/PlantsVsZombies'' plays almost entirely like a conveyor-belt ''Plants vs Zombies'' level, only occasionally attacking and becoming vulnerable.
* The fight with Ironhead in ''VideoGame/CaveStory'' takes up the entire level "Main Artery". However, Ironhead itself merely swims back and forth through the screen, occasionally shooting three puny shots at you. The level is mostly about fighting the swarms of Pufferfish that flood the screen, and dodging the blocks flying across the screen that deal CollisionDamage.
* The FinalBoss in ''AeroTheAcrobat'': A good half of the battle is spent chasing him upwards and upwards through the floors, tiers, and rafters of his laboratory.
* ''Franchise/SonicTheHedgehog'':
** ''[[VideoGame/Sonic3AndKnuckles Sonic And Knuckles]]'', Lava Reef Zone, Act 2. The fight with Robotnik begins with a forced-scrolling segment, then the meat of the fight involves dodging mines while leaping between moving platforms in lava. You don't directly damage Robotnik; you just survive until Robotnik destroys the machine with his own mines.
** ''VideoGame/SonicTheHedgehog 1'' has the Labyrinth Zone boss. While you can hit Robotnik the pre-requisite eight times, it's entirely unnecessary, and the level ends once you reach the top of a vertical shaft filled with obstacles that is slowly flooding with water.
** In ''VideoGame/{{Sonic Rush|Series}}'' Adventure, we have the Ghost Whale which you must enter, then work your way through an obstacle course.
** The first part of the Dark Gaia fight in ''VideoGame/SonicUnleashed'' is half [[spoiler:piloting a HumongousMecha made out of temples]] and half this, with Sonic running down [[spoiler:the aforementioned mecha's arms]] to hit Dark Gaia's weak spots.
** The fights with Captain Jelly and Admiral Jelly in ''VideoGame/SonicColors'', though you do still have to hit the boss in between the level-like segments (which can be done in one hit with a yellow Wisp in tow and some good aim).
** In ''VideoGame/SonicGenerations'', Perfect Chaos plays out this way. Mind you,this is fairly similar to how Perfect Chaos worked in the original ''VideoGame/SonicAdventure''; despite the fact that [[TookALevelInBadass you don't have Super Sonic for the fight]], the ''Generations'' boost mechanic works in almost the same way, so the only real differences are the addition of 2D sections and the method of scoring the final hit.
** Any of the bosses of the ''VideoGame/SonicRiders'' games, purely by virtue of the fact that it's a racing game. [[TropesAreNotBad This works out]], however, as it doesn't take any wild changes of the mechanics to get the fights to work in the context of the game.
* The boss levels for the video game version of ''WesternAnimation/ABugsLife'' are like this, as you have to collect 50 grain, find all the FLIK letters, and kill all the enemies with a gold berry in order to fully complete them, just like any other level. The fights against the Bird and Hopper are particularily good examples, as they take place in level-sized maze/canyon areas that involve a lot of climbing.
* [[DoesNotLikeMen Speed Buster]] in ''VideoGame/NoMoreHeroes'' plays like this. What makes her different from the other bosses is that she is at the end of the level, and that Travis has to make his way while avoiding her dreaded laser cannon. [[spoiler:To win, Travis has to knock down a telephone pole to destroy her {{BFG}}, then make his way to Speed Buster herself to win.]] This break from the normal boss structure apparently causes her to not be included in the game's score attack mode, a BossRush mode that allows players to fight a ranking fight of their choosing.
* All three encounters with Scarecrow in ''VideoGame/BatmanArkhamAsylum'' are this. After a few minutes of horror, you have to navigate a giant, fragmented landscape as a giant Scarecrow tries to spot you. At the end, shining a spotlight on him will dispel the illusion.
** Killer Croc in the same game. His "fight" consists of sneaking around his lair trying to collect plant samples without alerting him to your presence, and knocking him back into the water if he finds you.
** In ''[[VideoGame/BatmanArkhamCity Arkham City]]'', some side character battles can play like this. Folks like Riddler, Deadshot, or Zsasz can't stand go toe-to-toe with the Bat, but have advantages like hostages or powerful guns, so their battles consist of getting close enough to them to perform an instant takedown without alerting them to your approach.
* [[ColossusClimb Megaleg]] from ''VideoGame/SuperMarioGalaxy''.
* The [[BigBad Bowser]] battles from ''VideoGame/SuperMario3DLand''.
** Also every fourth stage in the original ''VideoGame/SuperMarioBros''
** As well as Bowser in ''VideoGame/NewSuperMarioBrosWii''.
** In ''VideoGame/SuperMario3DWorld'', the fight with Bowser [[spoiler:after transforming into Meowser, and then Double Meowser, at the end of the game. Although the screen is scrolling up and the player ''is'' tasked with keeping up, it's not so much an AdvancingBossOfDoom as Meowser is running around you and attacking at multiple points. However, getting to the end is really all that's needed]].
* There are quite a few ''VideoGame/GodOfWar'' examples, all full of [[VideoGameSetpiece Setpieces]], such as the giant living statue at the start of the second game.
* In ''VideoGame/MarvelUltimateAlliance,'' Galactus is less of an enemy and more of an incentive to move ''really fast'' as you fight your way through the rest of the stage he's encountered in.
* The level "The Flood" from ''VideoGame/HaloWars''. There's a giant alien brain on the other side of the level that you're supposed to kill, but it has no direct combat ability (although it is surrounded by Flood turret equivalents) and most of the threat to your units is typical Flood units. There are five Flood bases you can kill to weaken it, which eventually respawn, and if all five go down so does the boss without you even touching it.
* The Scarab Walker from ''VideoGame/{{Halo 2}}'', which was more of a platform or level segment than an actual boss. They became legitimate bosses in the third game.
* the Cydonia alien base on Mars in ''{{Videogame/X-COM}}: Enemy Unknown'' has a big alien brain that needs to be destroyed in order to beat the game, but it doesn't do anything and thus the level is really more like a standard alien base assault mission.
* VideoGame/StarFox1 had its alternate FinalBoss, [[spoiler: the Slot Machine]].
** Some of the ships in the Armada stage that you can destroy by flying inside them and destroying their core, making them glorified obstacle courses.
** The second to last "boss" of Starfox64 is some kind of running Golem in a temple. The emphasis however is on chasing him and dodging obstacles, and even if you do enough damage to kill him, he can't die till you reach the end of the obstacle course
* In ''SyphonFilter 1'''s third level, you chase Mara Aramov through a a DC Metro [[SinisterSubway subway tunnel]] while [[CorridorCubbyholeRun dodging trains]]. You can either snipe her while she's running, or you can chase her to the end and take her down there.
* Boss stages in ''VideoGame/{{Jumper}}'' games are generally normal levels with additional danger in form an enemy who is usually defeated as result of progressing through the stage. The Boss in ''Jumper Two'', however, gives a genuine boss fight in which he is defeated by [[TennisBoss reflecting energy orbs back at him]].
* The first and final bosses in ''[[VideoGame/MeatBoy Super Meat Boy]]'' play out like normal levels with a few extra hazards.
* Unlike in the main ''VideoGame/DeusExHumanRevolution'', the only boss in ''The Missing Link'', [[spoiler:Burke]], has no ContractualBossImmunity or any abilities that make him fundamentally different than a normal enemy. Your confrontation with him is really about getting through the gauntlet of soldiers to the room he's holed up in.
* The blackout in ''VideoGame/LuigisMansion''. All the previously lit rooms go dark, there are tons of powerful ghosts in all of them, and the amount of damage dealing fake doors increases.
* Balrog's stage in ''StreetFighterXMegaMan'' has Balrog at the far left side of the screen, occasionally jumping forward to attack. Mega Man can't damage him; he just needs to make his way past all the obstacles until Balrog steps on a shaky bridge and falls.
* The Xel'naga Temple in the ''Videogame/StarcraftII'' mission "The Dig" is presented in this way, with its own nifty health bar frame. Your objective is solely to [[ExactlyWhatItSaysOnTheTin dig]] your way through the temple's door with a giant mining laser. [[CaptainObvious Because it's a temple]], it can't move or fight you in any way, and the difficulty of the stage lies in its fanatical guardians. Note that in this case, you are encouraged to use [[DeathRay the mining laser]] to help defend your base as well as unlock secondary objectives, which does make tunneling through the door take longer; therefore the mission is slightly shorter if you're confident enough in your base defenses not to need it.
