''Mortal Kombat: Deception'' is the sixth fighting game installment in the {{Blood|ierAndGorier}}y ''Franchise/MortalKombat'' franchise. It was released for UsefulNotes/PlayStation2 and UsefulNotes/XBox in 2004 and for [[UsefulNotes/NintendoGameCube GameCube]] in 2005, and it takes place right {{after|TheEnd}} ''[[VideoGame/MortalKombatDeadlyAlliance Mortal Kombat: Deadly Alliance]]''.

At the end of that game, [[BigBadDuumvirate Shang Tsung and Quan Chi]] [[TheBadGuyWins managed to bring back]] [[SealedArmyInACan Outworld's ancient army]]. The opening cutscene brings us to them fighting Raiden. Once Raiden is down, they start fighting each other, with Quan Chi defeating Shang Tsung. However, while he was rejoicing with his victory, someone appears. [[BackFromTheDead It's]] [[BigBad Onaga]], the resurrected Dragon King, who wants Outworld back. Quan Chi and Shang Tsung tried to bring him down, with [[EnemyMine Raiden joining them later]]. In the end, neither the three of them could stop Onaga, and Raiden, in a desperate move, tried to do his most dangerous move... which has proven to be fatal only for the trio, as Onaga managed to survive to that and without taking much damage. With Raiden and the Deadly Alliance gone, now there's only one ruler.

It turns out that, while the events of previous games were taking place, Onaga, disguised as an Elder God emmisary, tricked a youngster named [[UnwittingPawn Shujinko]] into getting six {{MacGuffin}}s for him, across the realms. This, plus Reptile's body being used as a host, managed to bring back the Dragon King to life.

So, now, without any leader, and with five of the heroes being killed in battle, Sub-Zero trapped in the Netherrealm, and his pupil Frost being... [[JustForPun frozen]], the survivors of the battle against the Deadly Alliance (Kenshi, Bo' Rai Cho, Li Mei, Scorpion and the aforementioned Sub-Zero) are on their own against the forces of Onaga, which included the Tarkatan army, led by Baraka. Raiden, corrupted by Onaga's magic, became disgusted with the humanity in general, and revived Liu Kang as a zombie, sending him to a massive manslaughter. Kang's spirit, however, stays with Ermac, to help him save his friends.

Aside of the aforementioned ''[[BigBad Onaga]], [[UnwittingPawn Shujinko]], [[BladeBelowTheShoulder Baraka]], [[MesACrowd Ermac]]'' and the aforementioned returning characters from the past installment, the game managed to bring back several of the characters from past games, such as ''[[TheStarscream Tanya]], [[AmbiguouslyBrown Jade]], [[FanDisservice Mileena]], [[GasMaskMooks Kabal]], [[BadassNative Nightwolf]]'' and ''[[TheAtoner Sindel]]'', while adding several new faces such as ''[[CaptainErsatz Kobra]], [[FemmeFatale Kira]], [[TheAtoner Ashrah]], [[OrderVersusChaos Hotaru, Havik]], [[TheFaceless Dairou]] and [[ScaryBlackMan Darrius]]''. There's also a sub-boss team called ''[[ThoseTwoBadguys Noob-Smoke]]'', comprised of, you guessed, ''[[SdrawkcabName Noob Saibot]]'' and his minion ''[[ButtMonkey Smoke]]'' revived and reprogrammed in order to serve his new master, and two [=GameCube=] exclusive characters also returning: ''[[MultiArmedAndDangerous Goro]]'' and ''[[DropTheHammer Shao Kahn]]'', included due to the lack of online play in said version.

''Deception'' follows the 3D path the MK series has taken with ''VideoGame/MortalKombat4'' and ''Mortal Kombat: Deadly Alliance''. It also brought back the [[DeathTrap Stage Fatalities]], which were absent in the previous installment, [[EverythingTryingToKillYou now doable even during the match]], and increased the mayhem by adding several stages more than two traps, a ComboBreaker system, and a [[BetterToDieThanBeKilled hara-kiri]] move, which the character can use to avoid the Fatality. And, as you've seen above, it's the first ''Mortal Kombat'' game which assumes that TheBadGuyWins. (Ok, it's the BigBadDuumvirate from the previous game, but still.) Oh, and it's the first ''Mortal Kombat'' game to feature online play, in the Xbox and [=PlayStation=] 2 versions.

There's also a UsefulNotes/PlayStationPortable version called '''Mortal Kombat: Unchained''', which included all of the aforementioned playable characters of above (including Goro and Shao Kahn) and added the Deadly Alliance versions of ''[[ColonelBadass Jax]], [[EvilCounterpart Frost]], [[RebelliousPrincess Kitana]]'' and ''[[PlayingWithFire Blaze]]'', plus an Endurance mode.

Followed by '''VideoGame/MortalKombatArmageddon'''.

!!The game has examples of:

* ActuallyADoombot: Explaining the presence of Goro and Shao Kahn after their apparent death in ''Deadly Alliance'' ([=GameCube=] only).
* ADayInTheLimelight: There are several unlockable "Kards" which contain bios about the characters.
* AnachronismStew: Good luck trying to figure out what time period it is in Earthrealm. Shujinko hails from an Medieval style Chinese village, but at the same time there are US special forces, robots and movie stars hanging around. And let's not even start with all the Timeline inconsistencies.
* BetterToDieThanBeKilled: The hara-kiri moves.
* TheBusCameBack: Nightwolf, Kabal, Noob Saibot, Smoke, Sindel, Tanya, Jade, Mileena, Liu Kang. Shao Kahn & Goro join them in the [=GameCube=] version.
* CameBackWrong: [[spoiler:Raiden, after he releases his Godly essence in an attempt to stop Onaga. Liu Kang, after Raiden (after he CameBackWrong) reanimates his corpse.]]
* CameraScrew: The PSP port suffers from a vary annoying tic in Konquest Mode, where getting too close to any kind of map geometry causes the camera to lock onto it until you move far enough away or manually rotate the camera back onto Shujinko.
* TheCameo: The Dark Prison stage (which is set underneath Shang Tsung's island) features nearly ''every'' playable character from the series not in this game, the cast of ''Deadly Alliance'' included. A ''[=MK2=]''-era Shang Tsung also pops up on the balcony of the Deadpool stage. All of the non-playable characters from previous games can also be seen scurrying around the graves in The Krypt.
* CollectionSidequest: While Konquest Mode is ostensibly a large tutorial for learning the various characters' moves, a large part of it involves hunting down coins and treasure chests, which can be used to buy things (alternate costumes, music, extra stages, concept artwork, videos, etc.) in the Krypt.
* ComboBreaker: It can be used three times in a match, however.
* ContinuityNod:
** Noob-Smoke is a reference to how they both originally had Scorpion's moveset, both were secret characters in ''VideoGame/MortalKombat2'', and are both close to Sub-Zero.
** One of Li Mei fatalities in ''Deception'' mirrors one of ''Ultimate VideoGame/MortalKombat3'''s Brutalities.
* ConceptArtGallery
* DarkReprise: Raiden still has the same battle cries he always had but delivered in a much more aggressive tone, befitting his darker persona.
* DeadGuyOnDisplay: Before Noob Saibot found him, Smoke's deactivated body was being kept by Shao Kahn as a war trophy from his Earthrealm invasion in Mortal Kombat 3.
* DownerBeginning: See OhCrap below.
* EatTheDog: In the "Konquest" mode, you meet up with a woman in the starting town who is looking for her lost dog. You are directed to a butcher shop where the butcher has already killed the dog. He says something along the lines of "Oh no! I didn't know he was anybody's pet! I thought he was a stray!" He gives you the dog's butchered remains anyway. When you meet back up with the woman, her lines are...
--> ''"Oh no! Niko! I shouldn't have let him out of my sight!... oh well, would you like some Niko stew?"''
* EnemyMine: The opening movie starts with Shang Tsung & Quan Chi fighting Raiden, then turning against one another, before playing the trope straight when Onaga turns up and they all start attacking him instead.
* EverybodysDeadDave
* {{Expy}}: Darrius of Jax. Take a good look at a couple of his finishing moves.
%% Don't add FanNickname here. It goes on the Trivia tab.
* FartsOnFire: Uggh. Who knew Bo' Rai Cho had the stinkiest Fatality in ''Mortal Kombat'' history?
* GuideDangIt: Certain treasure chests in Konquest Mode only appear at certain times of the day on certain days of the week.
* HammeredIntoTheGround: Shao Kahn had this as a fatality using his own hammer.
* HotterAndSexier: What ''Deadly Alliance'' started, this game [[UpToEleven cranked it up a few notches]]. With the notable exception of [[TokenWholesome Ashrah]], just about every playable female has at least one {{Stripperiffic}} outfit (and even her alternate outfit isn't exactly what you'd call modest...).
** This game also featured the infamous crossover with ''Playboy'', where Mileena appeared sexy (but not naked). A special art piece was created for the magazine (but not actually featured in it) of Mileena in her alt costume, pulled away from her breasts with her sai's crossed over her nipples. The art is an unlockable in the Krypt (and was apparently a favorite desktop background for the developers of the game).
* {{Irony}}: The original Sub-Zero from ''VideoGame/MortalKombat'' had the classic "Spine Rip" Fatality, which involved ripping the opponent's head off with the spine still intact. Scorpion, who originally sought revenge against the original Sub-Zero over the death of his clan and family, adapts the classic Spine Rip Fatality as his own.
** Pull this on ether Sub-Zero (the current one) or Noob Saibot ([[spoiler:the original Sub-Zero]]) to really see a DeathByIrony
* KillEmAll: A great amount of the kombatants, including nearly all of the original cast, especially the Earthrealm characters (Johnny Cage, Sonya, Kitana, Jax and Kung Lao), are killed off at the beginning of the game.
* MeaningfulName: The second name of the game, "Deception." [[spoiler:It's about Onaga tricking Shujinko, who played a big part of the deal in reviving the former.]]
* MythologyGag: The design of Kira's Dragon Teeth knives comes from the knife Kano wielded in [[Film/MortalKombat the first movie]].
* LaResistance: Mostly notably Darrius.
* LukeIAmYourFather: [[spoiler: Noob Saibot is revealed to be the original Sub-Sero in this game. His reunion with his younger brother is less than ideal as he orders Sub-Zero's (the younger) former best friend, Smoke, to help rip him in half.]]
* MiniGame: "Chess Kombat" and "Puzzle Kombat."
* {{Mondegreen}}: Liu Kang performing his Bicycle Kick in this game makes it sound like he's yelling, "WHATAREWEGOINGTODOABOUTTHAAAAAAAAT?!!"
* NostalgiaLevel: Many of the arenas.
* OffhandBackhand: One of the loading screens shows Kenshi doing this to Kira via ''[[MindOverMatter telekinesis]]''... ''into a wall.''
* OhCrap: The opening movie comes with one for the player, as the first shot is of the stairs leading to Shang Tsung & Quan Chi's base from the previous game [[spoiler:''littered with the corpses of Johnny Cage, Kitana, Sonya, Jax and Kung Lao'']], and one in-universe when Onaga turns up.
-->'''Quan Chi:''' No! [[ThisCannotBe It cannot be]]!...
* PermanentlyMissableContent: In Konquest Mode, once you leave the village at the beginning, you can't get back in. So be sure you've gotten as many koins and open as many chests as you can before you do so.
* PlayableEpilogue: The Konquest Mode allows the player to still roam around the realms after finishing the main story. However, the player also gets the opportunity to find new chests that unlock either main protagonist Shujinko's special moves and [[FinishingMove Fatalities and Hara Kiri]] or chests that the player missed out on at the beginning village.
* PrecisionFStrike: If you knock Ermac off of the Sky Temple, you hear something you wouldn't expect from someone with his disposition.
--> "''RAAAAAAAAAAAGH'', [[note]]'''''SUUUCK IIIIIT!!!''''': and it's very easy to confuse the S for an F.[[/note]]"
* RingOut: In several of the arenas. This being Mortal Kombat, the loser is rewarded with a bloody death by way of Death Traps.
* RunDontWalk: Averted; there is a run button in Konquest Mode. Chances are you'll be holding that button constantly, since Shujinko's jog is pretty slow by comparison.
* SharedLifeMeter: The Noob-Smoke tag team.
* ShoutOut: Check [[ShoutOut/MortalKombat the page]].
* ShowsDamage
* SkeletonMotif: Havik is an AmbiguouslyHuman character who is missing the lower part of his face (starting at the nose) which was apparently ripped off, revealing his skeletal structure. He's not evil, though, just chaotic (he hails from Chaosrealm, after all).
* SpinningOutOfHere: Jade has a move called Vanishing Winds where she spins around a cloud of green smoke and reappears behind her opponent.
* TerribleTrio: Kabal, Kira, and Kobra.
* ThisIsGonnaSuck: [[http://www.youtube.com/watch?v=lQXItuLx21I Havik seems to think so about being knocked off of the Sky Temple.]]
* ThoseTwoBadGuys: Noob-Smoke. Though unwillingly bad in Smoke's case.
* UnwinnableByDesign: Several of Konquest mode's questlines have no ending.
** Also in the starter town, you can accept a quest to deliver a pot to another NPC somewhere else in town. If you leave the town before completing the quest, you'll figure out that you technically can't get back into the town.
* WhatAnIdiot: Raiden's thoughts about Shujinko's quest, in a nutshell. [[invoked]]
