Steam vents are somewhat common as obstacles in video games. Typically, they produce a cloud of hot steam right in front of themselves; this is the actual obstacle.

Such obstacles range from being minor inconveniences to being damaging. They are typically static or intermittent obstacles, but seldom move around, since the pipes attached to them don't. They may become GoddamnedBats if their hit detection is badly programmed. If they are minor inconveniences, they act as such by causing InterfaceScrew.

If the vents are being pushy rather than harmful, see VentPhysics.



* A number of these occur in ''VideoGame/BatmanArkhamCity''.
* ''VideoGame/BraveFencerMusashi'' has an area outside Grillin Village known as Steamwood Forest, where random steam pipes spew high-pressure streams of hot air. Some shoot out steam at regular intervals to provide temporary obstacles, and others continuously fire to create impenetrable barricades. After you repair the system that regulates the steam vents, Steamwood (you have to do this twice during the story), the vents cease to be a problem.
* Sporadically used in ''Franchise/TheLegendOfZelda'' games. ''VideoGame/TheLegendOfZeldaTwilightPrincess'' not only has a few around Death Mountain, but while it's enveloped in twilight, a Goron even laments that the appearance of one particular fumarole makes the path "impassable".
* ''VideoGame/MetroidPrime'': Steam vents produce steam that can clog up Samus's visor temporarily.
** In the intro level for ''Super VideoGame/{{Metroid}}'', Samus needs to escape a space station, while avoiding gushes of steam coming out from practically everywhere. If you get hit by the steam, you lose precious time to escape.
** Happens again during the escape from planet Zebes, only the steam's escaping ''from the ground'' itself.
* ''ODT: Escape, or Die Trying'' had a level where pipes constantly leaked steam. And you had to use the pipes for moving.
* ''VideoGame/MirrorsEdge'' had steam vents in a few levels, requiring you to stop, find a nearby valve, and shut it off. The lengthy valve-turning animation turned these into some of the game's most irritating obstacles, as this is a game built around going fast
** Usually these vents will kill you if you try to just pass over them, but there's one in the [[EternalEngine Pirandello-Kruger]] level which will only cause mild damage, [[GoodBadBugs if it hurts you at all]], allowing you to [[SequenceBreaking entirely skip turning the associated valve]].
** In the {{iOS|Games}} version, these kill you faster than getting shot, and appear fairly often in levels that take place indoors.
* Some in ''VideoGame/LEGOStarWars'', at least the ones that release very cold air.
* ''VideoGame/TombRaiderAnniversary'': Damaged pipes occasionally blowing bursts of steam are seen in ''Natla's Mines''. The steam is blown at regular intervals, meaning Lara can easily climb past. Should she get hit, she'll merely lose some health, while staying attached to the pipe.
* VideoGame/{{Infamous}} has a couple of sections where Cole [=MacGrath=] must avoid some vents slewing some steamy ooze.

* In the third level of ''VideoGame/ViewtifulJoe 2'', an air vent serves as an obstacle in a puzzle. There are two settings you can activate. Either can block the path below, or let you ride the wind inside it, depending on which side you come from.

* They appear in both ''VideoGame/HalfLife'' games. You have to time your passage through some, but others are static and you have to find a valve to shut them off with.
* There is a steam vent puzzle in ''VideoGame/DukeNukemForever'' that doubles as a TakeThat at Creator/ValveSoftware.
* ''VideoGame/{{Blood}} II'''s [[DownTheDrain obligatory sewer level]] consists near-entirely of finding switches to turn off a series of steam vents blocking you from crossing a bridge to the exit.
* Played around with in ''VideoGame/FirstEncounterAssaultRecon'' - steam itself is rarely directly harmful to you, but half the time when you do see it something invariably explodes near it and replaces it with ''fire'', which is the real obstacle you need to get around.
* These appear in ''VideoGame/RiseOfTheTriad'' in both static and moving versions.
* ''VideoGame/MedalOfHonorFrontline'' has a couple of these, most prominently in the U-Boat level... which doesn't actually make a whole lot of sense.

* ''VideoGame/RemnantsOfSkystone'' has steam vents as obstacles, despite their supposedly having been untended for [[EternalEngine nearly two hundred years]], often acting just to make you schlep all the way around to try a particularly tricky threading-the-needle series of spikes and nasties.
* ''VideoGame/GuildWars2'' features this as one of the more common obstacles in [[MadScientist Inquest]] and [[SkyPirate Aetherblade]] bases. All cause some damage while a few will knock down the player as well.

* There are a few of these in the construction zone level of ''VideoGame/KendoRage''.
* ''VideoGame/SuperMarioBros2'' has whales in World 4 that spray geysers of water out of their blowholes. Touching the water spray from the side is dangerous, but standing on the spray is safe.
* ''Videogame/MegaMan5'' features damaging puffs of steam appear in Wave Man's stage. They also appear in Neptune's stage in ''VideoGame/MegaManV''.
* Variation: ''VideoGame/{{Battletoads}}'' has vents producing small puffs of poisonous gas that travel a short distance before dispersing harmlessly.
* There are a few steam vents in the Inferno Cavern of ''VideoGame/LaMulana'', especially along one vertical shaft that hides a way to the chain whip upgrade.
* ''VideoGame/MazeOfGalious'' has spots on various platforms that produce periodic bursts of steam.
* ''VideoGame/AnotherWorld'' had deadly steam vents in the area where you're rolling your way through pipes.
* This is often used in the ''Franchise/SonicTheHedgehog'' games.
* ''Batman Returns'' for the UsefulNotes/SegaGenesis has annoying steam vents throughout the collapsed building level.
* ''VideoGame/{{Rastan}}'' uses the fantastic equivalent of gargoyle-like stone blocks that release jets of blue flame.

* In ''Rock 'n' Roll'' by Rainbow Arts, explosions act like this; they can occur when the player sets off bombs, but it's far more common for them to naturally occur on certain tiles at a constant interval.

* ''VideoGame/StarCraftII'' features these on a number of multiplayer maps - they do no damage, but serve to break line-of-sight.

* One springs up in ''VideoGame/MartianDreams'' once you've gotten the steam power working. It prevents you from shortcutting to the exit, and that's all.
* The dungeon rooms in ''VideoGame/DotHackGU'' sometimes will have these alongside other {{booby trap}}s. They reduce your SP when you're hit.
* One mission in ''VideoGame/MassEffect2'' takes place on an abandoned space station where the only real danger are a few damaged pipes that emit powerful jets of steam.
* ''VideoGame/{{Undertale}}'': The steam vents in Hotland are actually useful, [[VentPhysics as the steam rising from them helps you jump between platforms]]. However, there is one puzzle where the directions in which the steam vents send you keep changing depending on where you land, and getting past it can take a while. There is also another room with lots of platforms with steam vents that can be quite hard to navigate your way around.

* ''VideoGame/ThunderCross II'' has them in the fourth level. Unlike most of the examples on this page, you can destroy them.

* In the World Adventures EP for ''VideoGame/TheSims3'', this is one of the traps in the tombs.

* In ''VideoGame/MetalGearSolid'', there's a blast furnace full of leaky pipes where you can pick up the optional body armor.

* ''VideoGame/CallOfCthulhuDarkCornersOfTheEarth'' has several. They are damaging and can cause interface screw if they are releasing toxic gas; they are part of a puzzle in one location where they need to be turned on in the correct order.
* A puzzle late in ''VideoGame/ResidentEvil3Nemesis'' involves shuffling active leaks in steam pipes. Successfully clearing a path nets Jill the [[{{BFG}} Rocket Launcher]].

* ''VideoGame/{{Odium}}'' has you activate a steam vent to remove some slime off a walkway. The steam then becomes an obstacle itself, to be deactivated by a different switch.

[[folder:Non VideoGame examples]]
* ''Series/DoctorWho'': [[Recap/DoctorWhoS32E5TheRebelFlesh "The Rebel Flesh"]]. The lower levels of the factory suffer from this. For bonus points, it's [[HollywoodAcid Hollywood acidic steam]] to boot.
* ''Film/ANightmareOnElmStreetPart2FreddysRevenge'': When Lisa is running through the old power station, several of her routes are cut off when Freddy causes scalding steam to be blasted across her path.
