''Undercover Cops'' is an arcade BeatEmUp by Creator/{{Irem}} later ported on the SuperFamicom, designed by most of the staff that would later make the ''MetalSlug'' series.

In 2043, a city is assaulted by the MadScientist Dr. Crayborn and his large gang of thugs. To counter this, the mayor hires a group of three professional "city sweepers" to clean the streets. They are:

* '''Zan Takahara''': A former karate champion stripped of his black belt after accidentally killing a man in self-defence.
* '''Matt Gables''': A football player falsely accused of murder and banned from the sport because the officials thought he was too violent.
* '''Rosa Felmond''': A vigilante on a RoaringRampageOfRevenge after her lover was killed by thugs.

Featuring the same detailed sprite art and subtle humorous touches later seen in ''MetalSlug'', along with a large numbers of moves rivalling the likes of ''VideoGame/ViolentStorm'', this game is frequently seen as a classic by hardcore fans of the beat'em up genre. However, while it did find a cult success in Japan, it was impaired elsewhere by a [[BadExportForYou severely gimped]] World release and no exports of the home version.

Later received a sequel on the GameBoy called ''Undercover Cops Gaiden'', which is a [[GenreShift turn-based board game]] instead of a BeatEmUp, and a SuperDeformed manga adaptation by the infamous guro artist Waita Uziga.

!!Tropes:
* ActionGirl: Rosa.
* AfterTheEnd: Nothing in the backstory actually indicates this, but several backgrounds are very much post-apocalyptic in design, and the game takes place in the same universe as ''VideoGame/InTheHunt'' and ''Air Duel''.
* AmazonianBeauty: Rosa.
* AssKicksYou: Rosa.
* BadExportForYou: The overseas version was based on an earlier build than the Japanese one. More than half of the moves weren't implemented yet (no alternate combos, final throws, dash+jump attacks or super desperation moves), the music has bad quality (the composition is the same but their arrangement is downright sub-8bits), the background of the first half of the second stage is different and ldxx detailed, and many background details and voice samples weren't added yet. A conversion kit was released known as "Alpha Renewal Version", which adds everything that was included the Japanese version to the overseas releases, but it's very rare.
* BareYourMidriff: Fox.
* CuteBruiser: Rosa, who despite having a pink heart motif and some adorable poses is still [[AmazonianBeauty built like a brick house.]]
* DegradedBoss: Generic, already-damaged clones of Parcs appear in the final level. And just as Parcs tried to drop you into a trash compactor, the T-900s try to drop you out of the skyship's open doors.
* DoNotDropYourWeapon: Minor enemies in the game wield [[GrievousBottleyHarm broken bottles]], [[KnifeNut knives]], [[AnAxeToGrind short handled battle axes]], [[TorchesAndPitchforks torches]], and [[BatterUp baseball bats]]. Upon killing them, they do not drop their weapons.
* DownerEnding: If you don't stop Dr. Crayborn from dropping a nuke on the city (which is REALLY easy to do) at a certain point of the final level, you get a [[MultipleEndings Bad End]] with a side of NonStandardGameOver.
* DubNameChange: From the Japanese version to the English version.
** Rosa to Flame
** Zan to Claude
** Matt to Bubba
** Parcs to Cue Ball
** Fransowors to Fatso
** Moguralian β to Gunpuncher
** Balbarotch to Cone Head
** Dr. Crayborn and most of the other mooks keep their names.
* ElevatorActionSequence: Happens in the middle of the second stage.
* TheEndOrIsIt: The ending credits shows [[spoiler: Dr. Crayborn's handcuffs on the ground, along with an ominous laugh, indicating that he escaped.]]
* EvilKnockoff: You have to fight a clone of each playable character in the final stage, right before the final boss.
* ExtremityExtremist: Almost all of Zan's attacks rely on kicks.
* {{Fartillery}}: Moguralian β attempts to do this.
* FlunkyBoss: Fransowors's first phase will have her often use her jackhammer to bring a Fox down (occasionally, she'll instead get a motorcycle to drop down on you). If you have enough time on the clock, you can keep fighting Fox after Fox for extra money before going after Fransowors herself.
* FragileSpeedster: Rosa
* GaidenGame: ''Undercover Cops Gaiden'', a board game-style spinoff.
* {{Gonk}}: Balbarotch, if the [[http://flyers.arcade-museum.com/?page=flyer&db=videodb&id=1273ℑ=1 arcade flyer]] is anything to go by (he's to the left of the title; you can tell that's him by his helmet).
* GlassCannon: The mole men can do heavy damage but they all die in one hit (except in the US/World Versions).
* GratuitousEnglish: Not the game itself, but the ''soundtrack'': Most of the names used in the OST doesn't have ''any kind of sense'' and we have some gems like ''Sarah Sowertty'', ''Chaca Chaca Move Ya'' and ''Indifferent Zero Other.''
* JackOfAllStats: Zan.
* ImprovisedWeapon: Being a beat'em up, this is expected. However, while most games in the genre feature small weapons such as knives or bottles, this game take it to the next level, letting you pick up the wrecks of a Hummer, swing concrete pylons or throw fishes at the enemies.
* KiAttacks: Each cop has one for their super desperation attack: Zan shoots bright energy explosives (Zan Bombs), Rosa summons a giant blue energy wave (Arch Saber), and Matt charges his hands and launches himself up and down the air across the screen like a rocket (Atom Bomber). These moves are very powerful and cost a huge chunk your health, so use wisely.
* ManOnFire: Balbarotch when he's defeated. The last hit causes all the weapons he's keeping in his cloak to begin to overload, as a result igniting him, making him dash around shrieking in pain, and the fire keeps ''growing''...Until the weapons finally ''explode'', leaving '''''nothing''''' of Balbarotch ...[[NightmareFuel except his bones and helmet]].
** Worse, in the Super Famicom version you can knock off the [[ImAHumanitarian head and eat it for health]] [[ScoringPoints and bonus points]]. But be sure to eat it 1 second before the screen fades to black because it kills you if you eat it too early.
* MightyGlacier: Subverted with Matt. While he is the slowest, he is the only one that can actually run (his "dash"), compared to Zan and Rosa, who just dash. Matt's "dash" also goes further than the other two characters dash.
* MultipleEndings: The ending varies between the characters being used and the number of people playing.
* NonindicativeName: There's nothing "undercover" about these cops.
* OcularGushers: Fransowors once she has less than a full bar of vitality left.
* OneWingedAngel: For the final battle, Dr. Crayborn locks himself on one of his experimental machines and turns himself into an huge monster. At first, the tiny bit of vitality he has suggests ClippedWingAngel...until he puts himself ''back'' in there after you take out that bit of vitality. Cue the version with two full boss vitality bars...
* PersonalityBloodTypes: The AttractMode in the English translation list blood types in the Character profiles (the Japanese version doesn't, oddly enough).
* RecoveryAttack
* RummageSaleReject: Justified. The game does take place AfterTheEnd.
* SdrawkcabName: Parcs.
* SequentialBoss: Parcs. First, you fight it in its human form along with a few mooks. After half of its lifebar is removed, it gets damaged, losing its exoskeleton and RocketPunch right arm, and you fight it as it attempts to throw you in a trash compactor.
* SpiritualSuccessor: To the ''Film/{{Hook}}'' arcade game, and would later get one in the form of ''VideoGame/NinjaBaseballBatMan''.
* ShoutOut:
** The clones of Parcs that shows up in the final level are called [[{{Terminator}} T-900s]].
** Some of the collectable items are [=TVs=] with a picture of the first boss of ''VideoGame/{{R-Type}}'' on them.
** The police van in the credits look and act just like the buggy of ''Moon Patrol''.
* {{Stripperiffic}}: Fox, oh so much. She wears nothing but tank top (no bra), a thong, and boots.
* UnusableEnemyEquipment: As mentioned above in DoNotDropYourWeapon and ImprovisedWeapon, the playable characters cannot wield knives, bottles, bats, or axes. This is kinda justified considering they can all shoot energy and wield weapons 2 or 3 times their size.
* TokenTrio: Zan (Japanese), Rosa (token woman), and Matt (white guy)
* TheVerse: The appearance of Crayborn's huge D.A.S helicopter in the final level, and the pre-level screen listing the target as "D.A.S", suggests this takes place in the same universe as ''VideoGame/InTheHunt'', ''Air Duel'' and ''Gunforce 2''.
* WrestlerInAllOfUs: Zan has a grab where does the [[NinjaGaiden Izuna Drop]] (minus the spinning).
