Undercover Cops is an arcade Beat 'em Up by Irem later ported on the Super Famicom, designed by most of the staff that would later make the Metal Slug series.In 2043, a city is assaulted by the Mad Scientist 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.
Featuring the same detailed sprite art and subtle humorous touches later seen in Metal Slug, along with a large numbers of moves rivalling the likes of Violent Storm, 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 severely gimped World release and no exports of the home version.Later received a sequel on the Game Boy called Undercover Cops Gaiden, which is a turn-based board game instead of a Beat 'em Up, and a Super-Deformed manga adaptation by the infamous guro artist Waita Uziga.
After the End: 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 In The Hunt and Air Duel.
Bad Export for You: 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.
Degraded Boss: 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.
Flunky Boss: 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.
Gaiden Game: Undercover Cops Gaiden, a board game-style spinoff.
Gonk: Balbarotch, if the arcade flyer is anything to go by (he's to the left of the title; you can tell that's him by his helmet).
Glass Cannon: The mole men can do heavy damage but they all die in one hit (except in the US/World Versions).
Gratuitous English: 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.
Improvised Weapon: 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.
Ki Attacks: 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.
Man on Fire: 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 ...except his bones and helmet.
Worse, in the Super Famicom version you can knock off the head and eat it for healthand 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.
Mighty Glacier: 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.
Multiple Endings: The ending varies between the characters being used and the number of people playing.
Ocular Gushers: Fransowors once she has less than a full bar of vitality left.
One-Winged Angel: 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 Clipped Wing Angel...until he puts himself back in there after you take out that bit of vitality. Cue the version with two full boss vitality bars...
Sequential Boss: 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 Rocket Punch right arm, and you fight it as it attempts to throw you in a trash compactor.
Token Trio: Zan (Japanese), Rosa (token woman), and Matt (white guy)
The Verse: 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 In The Hunt, Air Duel and Gunforce 2.
