[[caption-width-right:320:Not even the VersusCharacterSplash would make a mundane quest [[MundaneMadeAwesome any more epic.]]]]

->"''Giant rats? It's like the start of every bad adventure tale my grandfather used to tell.''"
-->--'''Ser Gilmore''', ''VideoGame/DragonAgeOrigins''

You're a brand new adventurer, setting out for fame and fortune, and probably about to get caught up in an epic plot to unmake reality as we know it, which only you can foil.

But first, can you clear out the rats in my basement?

A common early quest in many [[RolePlayingGame RPGs]], particularly of the Western, tabletop-derived variety. Rats may be [[RodentsOfUnusualSize of unusual size]], or substituted with some similarly non-threatening and easily killed critter (the Eastern equivalent is typically one or more slimes), and indeed the basement may well be a different room entirely. This may even be part of the game's combat tutorial. Whatever the specifics, there's an area filled with small squishy things that need squishing. Get to it.

Often considered a classic hallmark of the genre, and is likely to be included simply as a nod to tradition. Or, as is becoming more and more common, parodied with an unusual variety of rats.

Subtrope of MassMonsterSlaughterSidequest. Not to be confused with GoombaStomp.

If you're still getting these sorts of quests when you're famous and powerful, it's time to start yelling "DudeWheresMyRespect"

* Played straight in Facebook game ''{{Mousehunt}}''. Though ''everything'' you fight is a mouse, the three weakest mice (White, Brown and Grey) the player encounters in the tutorial are based off regular varieties of real-life mice/rats while everything else is a NinjaPirateZombieRobot
* ''Franchise/TheElderScrolls''
** ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'':
*** The first quest for the Balmora Fighter's Guild has you killing a room full of rats.
*** ''Tribunal'' has the "Crimson Plague" side questline, which involves you killing some rats who are spreading the disease. (It averts the "beginner" quest part, however, as the quest soon escalates to you needing to kill a notorious DamageSpongeBoss.)
** ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]''
*** Plays it straight by starting you off in a dungeon/secret passage largely populated by rats, but inverts it with the first Fighter's Guild quest -- you're told a local woman has a "rat problem" in her basement, but the problem is that they're her pets and ''mountain lions'' are killing them.
*** When asked about "Rumors," some [=NPCs=] will [[LampshadeHanging point out]] how the tasks given to new recruits always seem to have something to do with rats.
** ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' also has an archetypal "clearing out rats" quest during the ThievesGuild questline, but it's not possible to do it before a number of other quests have been finished. Interestingly, you also fight a man named Hamelyn who's been expermenting on the rats, and he can actually be a little tough if you aren't prepared. Also, exterminating pests will only be a cover for the ''real'' task...[[note]]putting rat poison in the mead so the brewery fails [[TheInspectorIsComing the health inspection]].[[/note]]
* Subverted in most RPG created by ''Creator/FromSoftware'', particularly ''VideoGame/DarkSouls'' and ''VideoGame/{{Bloodborne}}'', rats can be seen early on, but it isn't you who stomp rats, [[RussianReversal it's the rats who stomp you]]. Not only they are [[RodentsOfUnusualSize twice larger than you]], they are also poisonous and [[ZergRush can swarm you]].
* At the beginning of ''VideoGame/BaldursGate'', you're asked to kill all the rats in a warehouse as part of the tutorial. The player character's journal contains a several-lines long [[DeadpanSnarker sarcastic rant]] on his/her [[LampshadeHanging thoughts]] on the 'quest'.
** Done again in ''VideoGame/IcewindDale'', where the first quest involves clearing out the basement of the inn. In this case weak bug enemies are used instead of rats.
** It gets parodied in ''Icewind Dale 2'', when you encounter another group of low level adventurers who were given the exact same quest and chose to solve it by tossing a cat into the room with the rats.
** ''VideoGame/BaldursGateDarkAlliance'' also begins with one of these, in the cellar beneath the Elfsong Tavern.
* ''VideoGame/NeverwinterNights'' has a [[http://nwn.bioware.com/support/patchdetails127.html demo module]] for rats and dire rats, named "[[TalkLikeAPirate Thar be Rats! Yarrr!]]"
** In ''Hex Coda'', a module by [[{{Tropers/Twoflower}} Stefan Gagne]], you're asked to get rid of the rats in the basement of a bar. Except that these are mutant, anthropomorphic rats, and the best course of action is not violence, but diplomacy -- you can simply ask them to leave nicely. The Journal entry for this quest is called "Ratstomp", making this the TropeNamer.
** Another fan module, ''VideoGame/ADanceWithRogues'' contains a rather nasty subversion: in the course of one Act I sidequest, the Princess finds herself alone in a sewer full of common rats... without [[NoGearLevel any of her gear or weapons]] and with [[InjuredPlayerCharacterStage just a single HP left]]. Suddenly, common sewer rats become a terrifying menace that can kill you in one hit and ''you can't even fight back''.
* The reboot of ''VideoGame/TheBardsTale'' starts with the Bard trying to impress a Barmaid by taking care of her rat problem. Turns out that the 'problem' is a giant, fire-breathing rat, and the locals regularly get a kick out of watching cocky adventurer types being beaten by it. Even [[Creator/TonyJay the narrator]] has a hard time [[{{Corpsing}} holding back his snickers]] as he describes your demise.
-->'''Narrator:''' [[SarcasmMode All hail the Bard; Rat Killer and Rodent Bane, who has bravely made the cellars once again safe for buxom barmaids and wanton widows!]] ...Or has he?
* ''VideoGame/KingdomOfLoathing''. The ''tutorial's'' RatStomp features bunnies(!), but you start out fetching a mosquito larva from a forest and clearing out a tavern owner's basement of rats - including the miniboss [[DastardlyWhiplash Baron von Ratsworth]]. However, the rats [[MookMaker just keep coming]] until you find and turn off the [[RuleOfFunny rat faucet]]. (This area is more significant than it appears; cranking the challenge level up beyond what a new player can handle can get you extra ''types'' of rats, potentially enabling a risk-for-reward shortcut against far more dangerous rats in a quest well down the line.)
* While ''VideoGame/WorldOfWarcraft'' indeed has some quests dealing with rats, they are never a challenge - even first level quests deal with wolves, panthers, bears, giant owl-bear hybrids or humanoid bandits. The only ones that come close are a couple concerning giant ''undead bats'' A more standard example of this trope would be the Kobolds, who are a race of mining rat-people that populate the early Human player maps.
* ''[[Videogame/{{Mardek}} Mardek RPG]]'': The rats have strange pipes instead of tails.
* In ''Series/ChinesePaladin 2'', one of the earlier mainline quests involve getting rid of a rat infestation. You pick up your first summon there, a giant rat-spirit who has earth-element attacks and can also steal stuff.
* The first thing you are required to do in ''VideoGame/FinalFantasyXII'' is to clear out the rats in a sewer. One of the local old guys even calls Vaan "Vaan Ratsbane" jokingly.
* One of the weakest enemies and most common first encounters in ''VideoGame/DungeonCrawl'' is the common brown rat.
* The old [[NoobCave Tutorial Island]] in ''VideoGame/RuneScape'' included a Battle 101 section, where you killed - you guessed it - giant brown rats. The rats in the "real world" are much smaller.
* ''VideoGame/PlanescapeTorment'' has a quest that gives you a bounty on rat tails. In keeping with Sigil's utter bizzarness, it is on ''Cranium'' rats, who become increasingly deadly sorcerers when in the presence of more of their kind.
* ''VideoGame/TalesOfSymphonia'' had a subversion; you don't fight rats until around halfway through the game. Even then still, at first they're not a challenge, but once you've shrunk down the rats are about 12 foot, and bust out boxing moves..
* ''VideoGame/DragonAgeOrigins'' has the human noble fight off an invasion of rats in their family's pantry in their origin story. Like all classic RPG tropes in the game, it's [[LampshadeHanging lampshaded.]] Providing the page quote above.
** Oddly enough, it's the only time in the entire franchise thus far that giant rats are an enemy.
* In the original ''Videogame/AloneInTheDark1992'' you must dodge rats in a wine cellar while looking for ammunition in that room. The rats can't be killed, but if they touch you, they wear down your life force and you are liable to die.
* In ''VideoGame/ArcanumOfSteamworksAndMagickObscura'', a Tarantian businessman asks you to clear the rats out of his warehouse, although this actually occurs in the second town you visit. There are a couple of opportunities earlier in the game to kill rats in dark rooms, though.
* ''VideoGame/{{Fallout}}''
** Your first task in ''VideoGame/{{Fallout 1}}'' is to head over to Vault 15 and see if they've got a spare water chip. As it happens, Vault 15 is now a bomb shelter full of mutant rats, and of course you start in the area outside Vault 13, also full of rats.
** ''VideoGame/{{Fallout 2}}'''s Trapper Town has a serious rat problem.
** And then, in ''VideoGame/{{Fallout 3}}'', one of the first quests you can obtain involves testing out a rat repellent. It involves hitting rats with a stick. That makes their heads explode.
** One of your very first tasks upon venturing out into the Commonwealth after escaping Vault 111 in ''VideoGame/{{Fallout 4}}'' is going to Concord. Along the way, you find the Red Rocket station near Sanctuary, which is home to [[PostApocalypticDog Dogmeat]], who helps you fight off a bunch of Mole Rats that have burrowed out from the cave under the station.
* ''VideoGame/{{Drakensang}}'' features a brewery full of rats. This is, however, not a low-level quest.
** Hilariously lampshaded later when the main characters ask to a Inn Keeper if he can obtain his trust by killing the rats in his cellar, making him angry at you. Then is double subverted when you find out that he does have giant rats in his cellar.
* ''VideoGame/{{Sacred}}'' 2 asks you to clear out a couple of cellars toward the beginning of the game. One of them is, predictably, full of rats.
* Your first quests in Noobshire from ''VideoGame/AdventureQuestWorlds'' has you ''saving'' rats rather than killing them, though one of the quests for Yulgar does involve cleaning out his rat-infested basement.
* Any RPG made by Spiderweb Software has a good chance of having rats as the very first enemies you fight, before you even go on any quests.
* One of the first things you do in ''VideoGame/BrainLord'' is help clear one villager's attic of rats.
* In ''VideoGame/{{Pokemon}}'', the first Pokémon you'll find in the wild will likely be a [[ComMons Rattata]] in the [[VideoGame/PokemonRedAndBlue first]] and [[VideoGame/PokemonGoldAndSilver second]] generations, and Patrat in the [[VideoGame/PokemonBlackAndWhite fifth]] generation.
* ''VideoGame/EveOnline'', even being a WideOpenSandbox, is not immune, except the rats are low level NPC pirates in spaceships...which the players call "rats", and the act of cruising for [=NPCs=] in asteroid belts "ratting". And not just because of the Fun With Abbreviations to be had with pi''RAT''e... player pirates don't get called that.
* ''Krusty's Fun House'' is an entire game about exterminating rats.
* In ''VideoGame/EternalSonata'', while there's a tiny part of the game before it, Allegretto and Beat's first battles are in an AbsurdlySpaciousSewer with a lot of rats in it. The only ones you're ''required'' to fight, however, are the ones in the bottleneck that serve as a combat tutorial for item use, Special Attacks, and light levels, should you elect to let it be one, and the boss and entourage at your destination.
* In ''VideoGame/EarthboundBeginnings'' you have to enter your basement towards the beginning of the game to retrieve a certain item, where there is a chance that you will fight rats.
* In ''VideoGame/SouthParkTheStickOfTruth'', an early {{side quest}} takes the New Kid to Skeeter's bar, where he is asked to rid the basement of a few mutant rats.
* One of the tasks you must perform in ''[[VideoGame/ThreeDUltraPinballCreepNight 3-D Ultra Pinball: Creep Night]]'' is to knock out a bunch of rats attacking a MadScientistLaboratory.
* Your first quest in ''VideoGame/CandyBox 2'' is to clear out some lady's basement of rats. It's also impossible to lose, since the rats die within 1-3 hits, and deal 1 damage to you. As a CallBack to the previous game, the rats aren't drawn in ASCII unlike all the other enemies, instead literally being shown as the text "rat".

[[AC: Fan Works]]
* Played straight and averted in ''Fanfic/TheKeysStandAlone: The Soft World''. In Gothmarik Citadel, rats are some of the opponents in there. But because the four are [[ActualPacifist Actual Pacifists]] and won't kill anything, John simply immobilizes them with warm ice timed to melt in a few hours.

[[AC: Tabletop RPG]]
* Any time you start out on lower levels in ''TabletopGame/DungeonsAndDragons'', you will be killing rats. Just like [[YouAllMeetInAnInn starting in a tavern]]. More recently, goblins are becoming the staple of low-level adventurers, but they're not a big step up.
** However, [[https://i.imgur.com/w7xm40n.png rats can be genuinely dangerous for non-adventurers.]]
* ''[[TabletopGame/SavageWorlds Evernight]]'', true to its [[ClicheStorm stereo]][[AffectionateParody typical]] [[StandardFantasySetting fantasy RPG]] roots, has one of the very first quests: kill the rats under the tavern.

[[AC: Webcomic]]
* ''Webcomic/TheNoob'', being a parody of the MMO genre, has plenty of fun with this trope. From the disappointment that the heroic adventure starts with collection [[TwentyBearAsses rat tails]], to the ExplosiveBreeder needed to repopulate the starting zone, to the elf-players looking down on the humans starting with ratstomping (while [[HypocriticalHumor starting elf players are all stuck killing spiders]]), to the starting-zone rats being made into [[DemonicSpider giant spiked monstrosities]] because the head developer ordered the team to ramp up the difficulty or be fired (he only meant the endgame dungeon).
