->''"SEWER ADVENTURE!"''
-->-- '''Creator/JhonenVasquez'''

A level that takes place in the [[AbsurdlySpaciousSewer sewers]] or a flooded building or some sort of hydraulic plant. Common mechanics of these levels include maze-like layouts, SuperDrowningSkills (or SuperNotDrowningSkills, depending on the game), narrow passages obstructed by rotating propeller blades of death, running water causing platforms to act like conveyor belts, and requiring the player to swim through sections of the level (sometimes the whole thing). Hitting switches to somehow divert the flow of water to flood or drain certain areas is also fairly common.

These traits, combined with a heightened temptation to abuse CopyAndPasteEnvironments, make these kinds of levels highly receptive to becoming ThatOneLevel, especially if they are {{Marathon Level}}s.

See also UnderTheSea for levels which are set in more natural aquatic environments. See also AbsurdlySpaciousSewer and/or TunnelNetwork for this kind of setting outside the scope of videogame levels.

(Not to be confused with DownLADrain.)

----
!!Examples:

[[foldercontrol]]

[[folder:Action Adventure]]
* ''VideoGame/BlasterMaster'''s Stage 4 takes place in a very large maze of a sewer. The on-foot sections contain pools of sewer sludge (some placed around precariously narrow foot paths), and if Jason falls into one, [[SuperDrowningSkills he dies]].
* There's a level in ''VideoGame/CaveStory'' where you have to be thrust along with the current, through huge groups of [[MalevolentArchitecture spikes and nearly-invisible foes]] - right after a ''boss'' that occasionally forces you to drown if you're not careful enough, all while firing extremely damaging projectiles at you. Thankfully, you can save first. Unfortunately, if you screw up in this area or the prior boss, the best ending is LostForever.
* ''Franchise/{{Castlevania}}'':
** ''VideoGame/CastlevaniaOrderOfEcclesia'' gives us two water themed worlds. The first of which is the Kalidus Channel, which you travel through on the way to the Minera Prison Island, and return to fully explore after finding a relic that allows free underwater movement. The second is the Somnus Reef, which is filled with enemies such that it's a chore to kill or even to sneak by, and most of them can poison you.
** The underground caverns in ''VideoGame/CastlevaniaSymphonyOfTheNight'', being filled with deep water pits and rushing waterfalls and all.
** ''VideoGame/CastlevaniaCircleOfTheMoon'' has the [[ExactlyWhatItSaysOnTheTin Underground Waterway]], worse yet, unless you get a certain item from a less likely location you'd think of, most players would [[SequenceBreaking Sequence Break]] and tackle this level first, making all the water in it poisonous. Doesn't help this level is filled with DemonicSpiders as well!
** ''VideoGame/CastlevaniaHarmonyOfDissonance'' had [[NonIndicativeName The Aqueduct of the Dragons]] which is actually just uneventful and filled with Fishmen and Mermen.
** ''VideoGame/SuperCastlevaniaIV'' had TheDungeon which feels more like this trope due to the abundance of toxic slime, and bullshit deathttraps.
* The Spring in the Sky in ''VideoGame/LaMulana'' is literally ''up'' the drain. And to get the item which prevents water from continuously damaging you, you have to do a little painful swimming first. You also need to buy a helmet first from a DungeonShop to have a chance to getting past the waterfalls, at which point, [[WallMaster Surprise Fish!]] The Tower of the Goddess doesn't appear to have water at first, but partway through you have to detour back to an earlier level to raise the water level. The swimming controls are not good.
* ''{{Shantae}}'': the Dribble Fountain, which is some kind of aqueduct/sewer thing, is the very first dungeon.
* ''Franchise/TheLegendOfZelda'' series has had its share of water dungeons that could be filed under this trope.
** ''VideoGame/TheLegendOfZeldaTheWindWaker'' has an old sewer system ''infested with rats and zombies'' underneath a private island cabana; Link must traverse this sewer system [[spoiler: to obtain one of the Triforce charts]]. Perhaps that's why Mrs. Marie, the schoolteacher at Windfall Island, was more than happy to hand over her Cabana Deed to a random child (Link) who just happened to have [[spoiler:20 Joy Pendants]].
** ''VideoGame/TheLegendOfZeldaTwilightPrincess'' also has a literal sewer as the first level for Wolf Link.
** ''VideoGame/TheLegendOfZeldaALinkToThePast'' after the first bit of castle and dungeon, Link has to escort Zelda out through the sewers. In the same game, the second dungeon of the Dark World, Swamp Palace, involves manipulating the flow and/or level of water.
** The Great Bay Temple in ''VideoGame/TheLegendOfZeldaMajorasMask'' is a huge hydroelectric plant where Link has to operate the color-coded pipes to carry water and make elevators with them. At one point, he also has to reverse the entire flow direction of the water to access previously inaccessible areas.
** The Ancient Cistern in ''VideoGame/TheLegendOfZeldaSkywardSword'' is this in the upper areas, with pipes that enable water-based elevators when the Whip is used, and a giant, golden statue raised or lowered with the help of two side waterwheels operated from a wall-placed lever (that is manipulated by the Whip as well). The lower areas of the dungeon, meanwhile, is BigBoosHaunt type.
** The Swamp Palace of ''VideoGame/TheLegendOfZeldaALinkBetweenWorlds'' resembles a big sewer in the middle of a swamp and requires you to solve elaborate water-raising/water-lowering puzzles to traverse.
* The second half of Lud's Gate, one of the most difficult areas in ''Franchise/TombRaider III'', is a large underwater maze, compounded by the lack of air pockets and the clumsy controls of the UPV.
* ''VideoGame/StarFoxAdventures'' has an aquatic-themed dungeon focused on pipelines, pressure, and lots of other fun stuff--the Ocean Force Point. It's not an actual sewer, being a rather pretty temple, but this is the closest place for it.
* ''VideoGame/{{Ys}} II'' has a maze of subterranean canals beneath the Solomon Palace.
* ''VideoGame/MetroidPrime 2: Echoes'' features the [[ThatOneLevel very difficult]] (even by this setting's standards) lower levels of Torvus Bog, which is otherwise a BubblegloopSwamp level. It's not the first underwater level in a ''Franchise/{{Metroid}}'' game, but it might be the first that forces you through half of it without the Gravity Suit.
* ''[[VideoGame/JakAndDaxter Jak II and 3]]'' have you go into plenty of sewer sections in Haven City, often to either get around barriers or do dirty work for Krew. Even Daxter hates it when Krew sends them off down there, but mostly cause he'll be running around in a smelly sewer [[RunningGag without pants]]. You also go under the Port to meet up with Sig near the end of ''II'', the entire first section of which has you traveling through an underwater section in the resident MiniMecha.
* ''VideoGame/{{Messiah}}'' has an entire level set in sewers with some jumping puzzles and brushes with squads of [[TheRevolutionWillNotBeCivilized Chots]] who live there.
[[/folder]]

[[folder:Action Game]]
* The sewer level in ''EnterTheMatrix'' was very long, full of difficult enemies, and [[AbsurdlySpaciousSewer for some odd reason]], had areas which were a several stories high ''underground'', requiring balance and platforming in order to successfully get through.
* ''VideoGame/TheMatrixPathOfNeo'' has a few of these, they tend to be long, full of SWAT teams, Agents and have really high places you have to cover allies...and blow up.
* ''NinjaGaiden'' has the AbsurdlySpaciousSewer that is The Aqueduct.
* Killer Croc's Lair in ''[[VideoGame/BatmanArkhamAsylum Batman: Arkham Asylum]]''. While it isn't overly large, the lack of your usual area map and the need to move as slowly and silently as possible make it one of the longest (and to some, most tedious) sections in the game. [[VideoGame/BatmanArkhamCity The sequel]] had a sewer level too but it was shorter.
* ''X-Men Legends'' has you trudging through the old sewers of New York city, the level itself is fairly straightforward, but the challenge comes from fighting off dozens of Morlock mutants. As you fight further in, the Morlocks only seem to grow in number, but it gets particularly frustrating once you encounter the [[GoddamnedBats Morlock Goth]], a mutant who can ''teleport and revive her fallen comrades'' and has a tendency to stay hidden in an entire mob of Morlocks who can easily slaughter your team without good crowd control.
* DevilMayCry2 had Dante go through a sewer in the third mission (Lucia had this as her second) and Lucia later got an aqueduct level.
* The Spider-Man game for the PS1 and PC had Venom's lair be in the sewer (with lava in What If mode).
* The Spider-Man 3 game had about three stages where Spidey tracked the Lizard through the sewers.
[[/folder]]

[[folder:Beat Em Up]]
* ''VideoGame/{{Battletoads}}'' Stage 9, is a sewer level. It introduces previously unseen swimming controls, combined with an entire level full of imaginative one hit kills. There are even timed sequences where you run from giant underwater gears, with controls unique to this level. This is arguably redundant because [[NintendoHard most every level in the game has this]].
* ''VideoGame/TeenageMutantNinjaTurtlesTurtlesInTime'' has Sewer Surfin' (which like the name says, [[AutoScrollingLevel scrolls automaticallly]] as you surf).
** Many ''TeenageMutantNinjaTurtles'' games have sewer levels, though they're [[JustifiedTrope justified]] by the fact that the Ninja Turtles actually ''live'' in the sewers.
[[/folder]]

[[folder:First Person Shooter]]
* ''Dark Forces,'' first in the ''[[VideoGame/DarkForcesSaga Jedi Knight]]'' series, features a sewer level plagued by the Death Star trash compactor monsters (complete with conveyor belt-like currents) and a series of places where water levels (if you can call the stuff water) must be changed in the proper order. Apparently, a sewer that's convoluted enough can double as an ElaborateUndergroundBase.
* ''VideoGame/{{Half-Life 2}}'' features an entire chapter, Route Kanal, where the player must traverse the canals and sewers of City 17 to escape from the Combine. While the chapter is not exclusively sewer-action, a good chunk of time is spent there.
* ''VideoGame/RedneckRampage'' had a particularly terrible example towards the end of the first episode - a very big, labyrinthine series of grey corridors and tunnels with lots of swimming and switch hunts, resulting a jarring shift in pacing from the rest of the game, that wasn't helped much by having the level populated entirely by [[GoddamnBats turd minions]].
* ''SeriousSam 2'' has a level at which Sam is forced to go through the sewer system to enter a castle. As he sees the entrance to the sewers he complaints to [[strike:Cortana]] Netricsa about it, and she says something about a mandatory sewer level in every game.
** The First Encounter also has a brief sewer section while moving through Karnak.
* ''VideoGame/DeadSpaceExtraction'', a rail shooter, features a sewer on a space ship. It's a pretty big ship, though, with a standing crew of over a thousand, plus water for the hydroponics area, so it's justified.
* ''VideoGame/BatmanDoom'' throws you into one of these as soon as you finish the first mission and the game proper begins ("Follow Killer Croc through the sewers"). Like in most such examples, the sewers are green, drab, moist, have enemies leaping at you from under water (these must be some tough gangsters to hold their breath in sewer water for so long) and have you walking on catwalks above big tanks of water.
* ''VideoGame/Left4Dead'' and ''VideoGame/Left4Dead2'' both have maps where you spend a brief time within a sewer:
** No Mercy, which has an AbsurdlySpaciousSewer with many passageways that lead to the hospital.
** Death Toll gets special mention for having an entire chapter take place in a sewer ([[FridgeLogic which unlike most other sewers is accessed through a building on high ground rather than a manhole]]).
** The Passing has the second part of the underground tour take place in the sewer, with a gauntlet to wrap it up. Also an AbsurdlySpaciousSewer, but wide open rather than maze-like.
** The Parish. You'll only spend a little bit of time in it; the real danger is the [[spoiler:field of alarm cars at which the manhole comes out.]]
** [[ThatOneLevel Cold Stream's gauntlet finale]] also takes you on a short romp through a sewer tunnel, right after the scripted Tank attack.
* The original ''CallOfDuty'' has a brief one, but it's not too sewer-levelish and contains no puzzles.
* The water treatment plant (Interval 3) and part of Interval 5 in ''[[VideoGame/FirstEncounterAssaultRecon FEAR]]'', as well as one of the first levels in its expansion pack Perseus Mandate.
* ''VideoGame/{{Blood}}'' and ''Blood II'' from the same developers as ''FEAR'' both also have sewer levels, both at near-opposite ends of their respective games - the first game waited until the third episode (of four), while the second game shoved you into one after about three levels.
** ''Blood'' also has several times when you have to dive in a more primitive outhouse pit. One such pit features an entrance to FireAndBrimstoneHell you must pass through to get to Tchernobog.
* The Kosovo and New York missions in ''SoldierOfFortune'' have a few sewer/drain levels.
* The first ''MedalOfHonor'' has the Sewer Chase level at the end of the first mission.
* This kind of level, or at least location within a larger level, is common in ''VideoGame/{{Doom}}'' {{Game Mod}}s. One example that comes to mind is the entire second part of ''Eternal Doom'''s map "Nucleus".
[[/folder]]

[[folder:MMORPGs]]
* In ''VideoGame/GuildWars: Factions'', the Undercity is a massive underground sprawl of sewers. The atmosphere is dark.
* Sewer maps appear '''a lot''' in ''VideoGame/CityOfHeroes'' and ''VideoGame/CityOfVillains'' when your character gets sent out on missions. The later game lampshaded it.
-->Sewer missions have always been beneath you. Hopefully someone will understand that someday.
** ''VideoGame/CityOfHeroes'' is simply packed with sewer missions where you're wading waist deep (depending on height) through toxic waste. These levels can be extremely infuriating, as some of them are remarkably easy to get lost in, not to mention the constant nagging feeling that you're wading around in the combined filth of an entire city.
* ''VideoGame/RagnarokOnline'' has the Prontera Culverts, which can house one of the weakest (and weakness is relative) Boss fights in the game.
* ''VideoGame/KingdomOfLoathing'' has the clan dungeon of Hobopolis, the fabled city of underground hobos. In order to access the dungeon, a player must first track down the city via a system of sewers.
* Tech-based superheroes in ''VideoGame/DCUniverseOnline'' have to go down the sewers of Gotham to take out Scarecrow in their first mission.
[[/folder]]

[[folder:Platform Game]]
* ''VideoGame/{{Batman|Sunsoft}}'' for the NES's Stages 3-1 and 3-2 (Underground Conduits I and II), part of Gotham City's AbsurdlySpaciousSewer system.
* ''VideoGame/EarthwormJim'''s "Down the Tubes" is a cross between this and UnderTheSea.
* ''VideoGame/MegaMan'' examples:
** ''VideoGame/MegaMan1'' had a drain/sewer portion in the second half of Wily Stage 3. (Also appeared in the remake, Powered Up.) Mega Man actually got a speed boost from the rushing water, although this meant that any powerups that enemies dropped that were passed up during the push forward couldn't be retrieved.
** The third Wily stage in ''VideoGame/MegaMan2'' was also a sewer, lined with SpikesOfDoom exacerbated by Mega Man's higher underwater jumping height.
** Toadman's stage in ''VideoGame/MegaMan4''
** Venus's stage in ''Mega Man V'' (GameBoy, not [=NES=])
** Toxic Seahorse's stage in ''VideoGame/MegaManX 3''
** Pumpman's stage in ''VideoGame/MegaMan10''.
** Aquaman's stage in ''VideoGame/MegaMan8'' had areas where swimming was necessary (a skill which has not been seen since.)
** The optional underground section of the intro stage in ''8''.
** Heatman's stage in ''VideoGame/MegaMan2'' takes place in the sewers, but with [[LethalLavaLand lava]] instead of water.
** ''Mega Man [[XtremeKoolLetterz Xtreme 2]]'' aka ''Soul Eraser'' for the GameBoy added instant death ''electrified'' water to Volt Catfish's stage.
** ''VideoGame/Rockman4MinusInfinity'' had Toad Man's stage, but also turned Cossack Stage 3 into one as well. It had various liquids with differing gimmicks.
* One of the most loathed sections of ''VideoGame/ConkersBadFurDay'', "U-Bend Blues", have you swimming through a long pipe filled with spinning fans that can instantly kill you with a single hit. And you have a dwindling OxygenMeter. And once you get ''out'' of the water there are platforms with lethal blades revolving on them. ''And'' getting killed at ''any point'' in the process sends you back to the beginning. And you must have collected enough money (namely $1000) in the previous levels to proceed, or else turn back.
* ''VideoGame/BanjoKazooie'', another Rare game for the Nintendo 64, has two full levels with this setting in mind:
** Rusty Bucket Bay, where the oil-contaminated water drains your OxygenMeter even on the ''surface'', doing so at twice the normal rate when you are submerged. The part involving swimming past instant-kill propellers to get a Jiggy is widely recognized as ThatOneSidequest, even by Rare themselves.
** Clanker's Cavern, the third level. While not as difficult as Rusty Bucket Bay, it requires you to spend quite a lot of time underwater and perform several tasks that are only hindered by the game's sub-par swimming controls.
* ''Banjo-Tooie'' has Jolly Roger's Lagoon, which includes various mechanical underwater sections like a metal fish and pipelines leading to other levels. Luckily, Mumbo's spell gives you SuperNotDrowningSkills for the entire level, making things a bit easier.
* The Sewer Level in ''HenryHatsworthInThePuzzlingAdventure'' is quite possibly the hardest in the game, which is [[{{NintendoHard}} saying something.]] If the second locked-in battle room doesn't kill you, the merciless AdvancingWallOfDoom directly afterward will.
* Seen in ''Franchise/CrashBandicoot'' quite a bit. ''[[Videogame/CrashBandicoot2CortexStrikesBack Crash 2]]'' has its "Sewer Or Later" level which just as fun as other stages and only remotely difficult on the Hidden and Skull Routes. ''[[Videogame/CrashBandicoot3Warped Crash WARPED]]'' has it's underwater levels which are fun but become very annoying under Time Trial mode. It also had the 'Tomb Wader' level set in a nilemeter where the water level constantly shifted. ''[[VideoGame/CrashBandicootTheWrathOfCortex Wrath Of Cortex]]'' brought back WARPED's underwater stages but due to somewhat poor level design and the horrible controls of the submarine, tended to be annoying even outside of Time Trial
* ''RatchetAndClankUpYourArsenal'': The snot-like amoeboids are ''everywhere'', sometimes spawning right behind and in front of you at once, the camera is awkward and won't turn unless Ratchet does, certain passages are blocked until you approach them from the proper side, the tunnels all look the same while the crystal locations are initially hidden, and best of all? If you want to find all of them, you have to find a special piece of equipment later in the game to explore the second half of the area...which is as lengthy as the first half. The sewers are rarely part of the major plot, but only for level grinding.
* The first chapter in ''{{Gish}}'', called Sewers of Dross. However, this is one of the easiest chapters.
* SNES game ''Mr. Nutz'' had the character go through a witch's cabin, only to find a shrink potion, fall off the top shelf in the kitchen and then finding himself ''literally'' having to go down the drain.
* The pipe levels in ''VideoGame/DonkeyKongCountry 3'' provided quite a bit of variation. "Dingy Drainpipe" was your standard "swim through the sewers" level, but "Demolition Drainpipe" and "Surf's Up" removed the water and combined the sewer levels with MinecartMadness, having you speed through the pipeline in a metal toboggan. "Low-G Labyrinth", another water-free level, added GravityScrew to a drainpipe level, while "Poisonous Pipeline" rather sadistically added the water back and [[InterfaceScrew reversed your left-right controls]].
* ''Franchise/SuperMarioBros'':
** World 2-3 of ''VideoGame/NewSuperMarioBros1'' is one of these in a desert.
** "The Impossible Maze" from ''VideoGame/YoshisIsland'', which provides the page image, involved no swimming, but it had a current which would push you to other parts of the pipeline. Getting through it requires pushing crates into position to get to pipes that are normally out of reach, and falling down the wrong path or losing your crate means starting over.
** Also in ''Yoshi'd Island'', Naval Pirahna's Castle also seems to be in a sewer.
** Slimy Spring Galaxy from ''VideoGame/SuperMarioGalaxy2'' also takes place inside a giant sewer.
* Stages 2-2 and 5-4 in ''VideoGame/{{Purple}}'' take place in sewer systems complete with fish and mines (that are out there to kill you). 4-2 has two with a strange background consisting of moving cherries (and creepy music to boot).
* Stage 3 in the arcade version of ''VideoGame/BionicCommando'', and Stage 2 in the NES / XBLA version.
* "Trial by Water," the fourth stage of the ''Wolverine'' game for the NES, involved swimming through narrow underwater passages lined with spinning blades.
* ''VideoGame/TeenageMutantNinjaTurtles'' has the dam level, the second half of which has DownTheDrain mechanics. It's not as hard as MemeticMutation would have you believe, but [[ThatOneLevel that still doesn't mean it's]] ''[[ThatOneLevel fun]]''.
* ''VideoGame/{{Turrican}} II'''s second level is like this, until you jump in the water and it becomes UnderTheSea.
* Parts of the colonial levels in ''VideoGame/{{Jazz Jackrabbit}} 2'' take place in the sewers.
[[/folder]]

[[folder:Puzzle]]
* Disney's ''Where's My Water?'', which is apparantly based on the UrbanLegend concerning the myth of alligators living in sewers.
[[/folder]]

[[folder:Real Time Strategy]]
* One of the underground levels in ''{{Pikmin}} 2'' is more similar to the sewer level; which you can only enter with blue Pikmin. It's also a bit more difficult than other "dungeon" areas thanks to the ''invincible'' Waterwraith that chases you down if you dawdle around on one level for too long.
** Straighter is the Shower Room. It's basically just a bunch of shower floors and drainpipes.
[[/folder]]

[[folder:Role Playing Game]]
* ''VideoGame/VampireTheMasqueradeBloodlines'' had a sewer level which was incredibly long and was full of high-level enemies around nearly every corner. It's even more difficult for the Ventrue class, as they cannot feed on the rats for health. Playing a Nosferatu requires you to stick to sewers for the ''majority of the game'', because you're so hideous looking that people seeing you is a violation of the {{Masquerade}}.
** Not to mention the absolutely insane amount of terror in that level--here's a hint: the first sub-boss, who [[DegradedBoss then becomes a regular enemy]], is [[spoiler:a huge, spiderlike centaur-thing created by grafting three women together, who bounds after you]].
* ''StarWars: KnightsOfTheOldRepublic'' has a level where you sneak into the Vulkar base via the Taris sewers.
** They were quite spacious too since they could fit a rancor down there.
* In ''Franchise/TheElderScrolls'' games, the larger cities often have sewer areas. ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'' has Vivec's underworks, which you thankfully don't have to spend too much time navigating. They are fairly wide-open, but have most of the annoying properties of sewer levels (diseased creatures, water that's hard or impossible to get out of, drab colors). The Imperial City sewers that feature in ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'' are at least as bad as Vivec's, and are also dark and not particularly interesting, either. You are also forced through them several times in the game--at least in ''Morrowind'', you could usually find a sewer entrance that was right next to your quest targets. The trope was averted slightly in an expansion of ''Morrowind'' that took place in Mournhold. Although you could spend a lot of time in that city's sewers, they were well-lit and felt like just another dungeon. Plus, they led to the cavernous ruins under the city, which, while not underwater, were certainly something worth seeing.
** ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' of course has the town of Riften, which has extensive sewers and is home to The Thieves Guild.
* ''VideoGame/FinalFantasyVIII'' has an incredibly frustrating sewer maze in which Quistis, Zell, and Selphie get stuck and all the areas look exactly the same. Plus, you have to go all the way back to the start if you make a mistake. On the plus side, the maze doesn't have any layers, so always taking a left (or a right) where possible will get you to the exit eventually.
* ''{{Summoner}}'' ([=PS2/PC/Mac=], Volition) has a semi-subversion…the sewer you have to enter in the big city is moderately well lit, plausibly plotted (most exits line up with the city above), and it's actually kind of fun as they're the size of the old Roman aqueducts. So what Goddamned monster do you find crawling in those tunnels? Bats? Rats? Giant bugs? no, GODDAMNED GOLEMS. And it's hella fun, as the topside fights with basic imperial soldiers and random encounters are the boring ones.
** The problem with it is that you're ''forced'' to go through the place from end to end at least five times, including several puzzles, and it doesn't change at all.
* The castle basement in ''[[VideoGame/MarioAndLuigiSuperstarSaga Mario & Luigi: Superstar Saga]]'', where the brothers have to fix the plumbing (they ''are'' plumbers, after all). [[spoiler: It ends up being a trap.]]
* There are sewer systems under the the HubLevel towns in both ''VideoGame/PaperMario'' and its sequel, ''VideoGame/PaperMarioTheThousandYearDoor''.
* There was also Kerokero Sewers in Super Mario RPG.
* The first dungeon of ''BaldursGateDarkAlliance'' is a sewer. [[AbsurdlySpaciousSewer It is used as a warehouse and as a base of operations for the bad guys, and has entrances to the thieves guild and the church.]] It also helpfully shows off the games water graphics.
* ''BaldursGate2'' starts with the player and the party making their escape via some sewers. Later on in Athkatla, there is another major quest (The Unseeing Eye) that takes place in the sewers. Then there is the area connecting the [[WretchedHive Copper Coronet]] and the slavers' base.
** Baldur's Gate 1 has an entire sewer area under each of the eponomous city's town areas (Meaning you could traverse the city underground) this is generally not needed aside from a sidequest or two.
* In ''VideoGame/PokemonRanger'', the player must explore a dungeon called the Waterworks. It's exactly what it sounds like... except it's infested with poisonous gunk Pokémon called Grimer and Muk, which are polluting the water for the entire city. These Pokémon create slippery slime literally everywhere they go. So not only do we have the usual sewer level fare, but we also get [[FrictionlessIce Frictionless Slime]].
** The trope was {{Lampshaded}} as well; multiple characters complained about how bad it smelled down there, and one RedShirt was close to vomiting every time you spoke to him (which is often).
* ''VideoGame/PokemonBlack2AndWhite2'' takes you into the Castelia City Sewers,complete with Grimer,Rattata and [[GoddamnBats Goddamn Zubats]]. At least if you find the small aboveground abandoned lot area, you get a shot at wild Eevee for the first time in history (not counting Gen IV's trophy garden).
* VideoGame/DeadIsland has the player need to go through the sewers to reach first the Town Hall, and then the Supermarket, and then back out the same way in the second act. In Ryder's Campaign, you need to use the sewers to get into the prison.
* VideoGame/DarkSouls is home to the Depths. The area is a disgusting, pus covered sewer filled with giant evil rats, dangerous slimes, cannibals, the Gaping Dragon, and most dangerous of all, the basilisks.
* The Moaning Well level in ''VideoGame/NappleTale'' does not have any smelly sewage (it's a well; that would be unsanitary,) but it does involve a number of water level switches and a [[MinecartMadness water slide sequence]].
* ''VideoGame/ChronoTrigger'' has the [[ExactlyWhatItSaysOnTheTin Sewer Access]]. Although it is accessible when you first visit 2300 A.D., it is entirely optional at that point. By the time you're actually required to go through it, you're likely to be significantly over-leveled compared to the enemies there.
* ''VideoGame/ChronoCross'' has the sewers under Viper Manor. Despite a somewhat annoying quantity of enemy encounters (which are usually difficult to avoid due to the cramped passageways), the area itself is mercifully short.
* The Kislev Sewer in ''VideoGame/{{Xenogears}}'' is often considered ThatOneLevel due to a complicated maze-like layout, a high random encounter rate, and ThatOneBoss at the end.
* ''VideoGame/MightAndMagic VI'' has the Free Haven Sewers, ''X'' has the Karthal Sewers -- both need to be passed as part of the main quest. ''VII'' has the Erathia Sewers, but they only play a part in sidequests (although if you have a Thief in the party, it is ''almost'' obligatory, as their class promoter is in the sewers).
[[/folder]]

[[folder:Stealth Based Game]]
* The sewer level in ''VideoGame/MetalGearGhostBabel'' is generally considered to be pretty good, although mostly because the music is cool. The sewer/swimming level in ''VideoGame/MetalGear2'' was also reasonably inoffensive, since it helped you get between the Zanzibar Building and the Tower Building without having to get through Maze Wood and the deeply annoying Nariko Sand stage - but if your finger slipped, you could find yourself washing up on the wrong bank and having to backtrack a good half of the game with next to no health and a face full of mines.
** Let's not forget Big Boss' escape from Groznjy Grad in ''VideoGame/MetalGearSolid3''. This was fairly short and the challenge mainly came from the lack of equipment as opposed to typical sewer level mechanics.
* The New York Sewers in ''SyphonFilter 2'', and the Warehouse District sewers in ''The Omega Strain''.
* The Cloaca Maxima Romulus Lair from ''VideoGame/AssassinsCreedBrotherhood''.
* The Thieves' Guild level from ''[[{{VideoGame/Thief}} Thief Gold]]'' consists mostly of navigating through a series of sewers in order to reach different locations where treasure is stashed. Problem is, not only are the sewer treks long-winded and many, the tunnels are usually stuffed with bad guys that it can be tricky to overcome because of the level design. And because of the game's extremely minimalistic map system, it can be very hard to tell which way you're going, let alone which way you're supposed to go. It's so bad that fans often label it as the worst level of the entire ''series''.
* Vattic and Jayne escape from the insane asylum through the sewers in ''VideoGame/SecondSight''.
[[/folder]]

[[folder:Survival Horror]]
* ''SilentHill1'' is a rare example of having all the problems associated with this trope, but actually making it work. The sewer level is repetitive, dark, filled with annoying enemies and removes your monster detector to boot. All of this combines to make for one hell of a claustrophobic and eerie run, exactly what the game is aiming for.
** As a direct sequel to the first game, ''SilentHill3'' recycles several locales as [[ShoutOut ShoutOuts]]. The sewer level is one of them.
** ''SilentHill2'' has the Labyrinth and the flooded DarkWorld hotel basement.
** [[SubvertedTrope Subverted]], though, in the ''SilentHillShatteredMemories'' re-imagining: the sewer level comes across as the next big scenario, but turns out to be a minor, brief, uneventful sequence lasting a short stretch and holding no encounters with anything or anybody.
* Any ''Franchise/ResidentEvil'' games set in Raccoon City will have one of these. Such as the [[SharkPool shark-infested]] flooded basement of the guest house in the first game.
** Hell, take ''VideoGame/ResidentEvil4'', which is set in Spain. You get a regular urban-ish sewer level underneath an ancient castle that also introduces a rather annoying (as in ''invisible'') enemy type armed with a OneHitKill attack.
* ''Videogame/AloneInTheDarkTheNewNightmare'' has a sewer level early on in Edward's scenario. Though not very long, Edward's speed is halved by being partly submerged in water, and the place houses a particularly nasty EldritchAbomination that will pop from beneath to OneHitKill him if he takes too long to reach the exit. Except trying to speed up catches the creature's attention. You spend the level alternating between slow/fast pacing and trying to hold off the creature with all your ammo, which can knock it back unconscious for a few seconds AT BEST.

* Inverted in ''VideoGame/GearsOfWar'' where you are required to go through a sewer, and you make the other people in your group go through it while your character laughs at them at every opportunity.
