Back to the Future: The Game: When you return to an alternate 1986 where Kid Tannen wasn't arrested, the Tannen family is now a crime family that rules Hill Valley. If you choose the option that says "Where are the police?" Marty will say "You better get out of here before my dad calls the cops." Riff will respond with "The cops? We own the cops."
Batman: Arkham Origins: The whole Gotham City Police Department is on the take somehow, with the rest being too afraid to stand up. Especially prominent in Commissioner Loeb and Branden. The only exception is James Gordon (who is not yet commissioner at this point), as one of Edward Nigma's extortion tapes has Anarky call Gordon the only clean cop in Gotham.
LAPD Detective Ben McCall is on the lighter end of the scale; he steals petty cash from criminals to help pay for the medical expenses of the child of one of the many hookers in his jurisdiction that he's protecting, he otherwise has a very strong sense of justice (although he also has anger issues and is prone to Cowboy Cop behavior as well as the Jack Bauer Interrogation Technique). By "street cop" standards, he's practically a Boy Scout.
DEA Agent Eddie Guerra is on the much more extreme end of the scale; he's secretly running a network of street dealers to sell drugs for him, in order to pay off his huge gambling debts. He also sets up an informant to be murdered because he was worried Internal Affairs was getting to the guy. It also turns out he was The Mole and helped the Cartel abduct key witness Jessica Stone because they owned his gambling debts.
FBI Agent Kim Evans is by all appearances an idealistic Good Cop, but is (reluctantly) willing to commit crimes, obstruct the investigation, and outright murder witnesses when ordered to do so by the director of the FBI, supposedly for The Greater Good (although it turns out most of her crimes were the result of her being misled by the director, who's the cartel's mole).
Capella's Promise has the Emissaries, who are supposed to be a peacekeeping organization for Ilnacia. Despite that, they turn a blind eye to and even accept bribes from illegal slave traders. However, Mares and Vargas, two members of this organization, consider it a necessary evil because they need underground connections to hide Velk and Shena from their corrupt king.
In Disco Elysium, the Detective can end up taking bribes to look the other way with his partner Kim Kitsuragi (who's typically By The Book) tolerating it depending on the circumstances. A late game quest involves him figuring out whether or not he was a mob asset in the past (with Kim noting that a good chunk of the police force are in the pocket of the mob boss La Puta Madre). The ending has Harry's actual partner Jean tell him that he was never a mob asset since no mob boss would ever trust someone as dangerously unstable as Harry.
The first Dead Rising has Jo Slade working as mall security, raping women and beating them with her nightstick.
Dead Rising 2 has Raymond Sullivan, who is working for Phenotrans all along.
You'll take on plenty of these as enemies (they'll even try to run you over in their cars) in the top-down arcade brawler Downtown. They did after all take a pay-off from the syndicate leader—And caught you looking on in the opening cutscene.
An Act 1 quest in Dragon Age II has Hawke helping their friend Aveline, who is a member of the Kirkwall city guard; together they expose her boss, Captain Jeven, as being one of these. As a reward for her efforts, Aveline is promoted to take his place. Later in Act 3, there's a campaign to smear Aveline's good name, and Hawke helps her discover that once again, Jeven is to blame.
Tashmann from the first Drakensang game: the first time you see him he's trying to use his badge to hire a prostitute for free.
The Elder Scrolls V: Skyrim: just about any Hold Guard could be dirty since, with the right perks and quests completed, you can persuade or bribe them into looking the other way when you commit a crime or inform them that you're a member of a particular group (say, the Thieves' Guild), but special mention goes to the guards in Markarth (who frame you for a murder and throw you in maximum security prison as part of a quest) and Riften (whose first interaction with you is to try and shake you down).
The Brass Blades that patrol the city of Ul'dah and surrounding areas in Final Fantasy XIV. If you start the game as a Gladiator, Pugilist, or Thaumaturge, The very first thing that happens in the game is a group of them attempting to shake down the merchant you're riding with. In the game proper, you'll occasionally find Brass Blades up to much, much worse.
Edi E. from Final Fight took bribes from the Mad Gear Gang, controlled a part of the city, and got the crap beaten out of him by the heroes. He later double-crosses the Mad Gear Gang by arresting its members during the events of Final Fight Revenge.
The Godfather: The Game doesn't just have beat cops, but also FBI agents on the take who will help you keep the other families under control if the vendetta escalates to open Mob War. In fact, if you want to pull off a decent caper in the game, you'd better pay off the cops beforehand so they'll look the other way.
Every Grand Theft Auto game has entire forces of dirty cops, some dirtier than others.
Ray Machowski worked for the Yakuza in Grand Theft Auto III. Machowski even has Claude assassinate his partner, fellow dirty cop turned informant Leon McAffrey, who worked for the Leone Crime Family in Liberty City Stories.
Officer Frank Tenpenny from Grand Theft Auto: San Andreas, the main Big Bad of the game, is one of the most iconic (and horrific) examples of a Dirty Cop in the history of video games. He likes to think of himself as a "Knight Templar", but at his core, he's nothing more than a thug in uniform who uses his police badge, his influence, and his connections for his own criminal and corrupt purposes. Since his actions are not productive at all, Tenpenny is far from someone who wants to do good, not even in an extreme or twisted way. In fact, his way of dealing with gangs is more reminiscent of how a mob boss would do it than that of a police officer.
Francis McReary in Grand Theft Auto IV. Packie claims that Francis is even more crooked than himself, Derrick and Gerry, who are all professional criminals.
A group of NOOSE and FIB Agents in Grand Theft Auto IV: The Ballad of Gay Tony, who intend to frame Ray Bulgarin by planting fake evidence in his truck. They're killed off in the mission "Going Deep".
Grand Theft Auto V has corrupt FIB agents Steve Haines and Dave Norton. Agent Haines plays it straight, forcing the protagonists to do his dirty work to hinder the IAA and make him look good. Agent Norton is a downplayed version; while he takes a monthly kickback from Michael as part of their "off-the-books plea agreement", he is more of a Reasonable Authority Figure than Haines.
The Blaine County Sheriff's Department is full of them, as they extort money from the drug dealers and prostitutes, and will staunchly defend that dirty money at all costs, taking it up a notch by bringing in the military and tanks.
Fitting the Film Noir inspiration of Grim Fandango, the only law enforcement seen in the game is Police Chief Bogen from Rubacava. He accepts payouts from gambling joints to allow them to stay in business, which Manny pays by rigging the roulette wheel in his favor every time he visits. He also arrests a dock worker for organizing a nonviolent strike.
Commissioner Kinsler is shown in Halo 3: ODST's audio logs to be concerned with nothing but his own personal interest, even as the Covenant are invading New Mombasa. If you manage to collect 29 audio logs, you'll find out that the cop whom you've been fighting alongside with in the data hive is on Kinsler's payroll.
The Hitman series has several antagonists who are corrupt members of law enforcement.
In Absolution, pretty much the entire sheriff's department of Hope, South Dakota, including the sheriff, Clive Skurky, is on the take from Blake Dexter. Also, in some of the Chicago levels, police officers work for the bad guys in some capacity. Even the ones that weren't, their behavior and attitude would earn them at the very least a reproachful reaction from their colleagues in any real police force.
L.A. Noire has the entire LAPD except for Cole Phelps and his partners. Except for his fourth partner, Roy Earle, on the Ad Vice desk.
Shows up in varying degrees in the Like a Dragon series, since cooperation between organized crime syndicates and the police is a necessity in Japanese society.
Masayoshi Tanimura, one of the protagonists from Yakuza 4, is far from squeaky-clean: he plays mah-jongg on company time and shakes down businesses exploiting migrant work (the latter of which he does to support his extended family in Little Asia). When push comes to shove, however, he's definitely heroic, especially compared to his mentor Suguichi, who's a Yakuza mole and Deputy Commissioner Munakata, who has been using resources to build secret prisons.
In Yakuza 5, it turns out that the Osaka Detective that shows up in all of the characters stories is actually the Chairman of the Omi Alliance.
In Yakuza 0, Homare Nishitani has the cops of Sotenbori in his pocket to the point that he uses a cell in the local PD as a hideout. Of course, since they're only loyal to his money it also means that they quickly turn against him when Dojima Family lieutenant Shibusawa hires them to kill him.
In Yakuza: Like a Dragon, Juro Horinouchi is the Deputy Commisioner of Tokyo who rose to his position via witness tampering that kept an innocent man in jail (who eventually committed suicide) and is a political lackey of the corrupt Governor of Tokyo Ryo Aoki. He serves as the personal nemesis of Koichi Adachi, who was the man who tried to save said innocent man and got demoted to a desk jockey at a DMV for getting in Horinouchi's way.
Like a Dragon: Infinite Wealth has the police in Hawaii, with many officers serving there making even the most corrupt cops depicted in Japan seem downright nice in comparison! Not long after Kasuga gets stripped of his clothes and passport and dumped on the beach, the arresting officer entertains the notion of pinning some unsolved murders on him, since his being a legal John Doe made him such a convenient fall guy (and a ticket to a speedy promotion). There is also Roman Reynolds, an officer who is in the pocket of the Barracudas, Hawaii's biggest crime syndicate, who helps keep the heat off of the Barracudas by Framing Up innocents such as party member Eric Tomizawa for their crimes.
Kazuya Ayabe from Judgment accepts bribes from criminals and leaks sensitive information for the right price, acting as Yagami's informant into the investigation on the Mole. As it turns out, the Mole is actually Ayabe's superior Mitsuru Kuroiwa, who started as an info broker like Ayabe before deciding murder and aiding in a massive cover up of a failed Alzheimer's drug was more his speed.
A major reveal in Lost Judgment is that Kazuki Soma, the boss of the RK gang, is actually an undercover cop/government spy who created the gang partly to centralize organized crime under the thumb of the government. However, he's also a cold-blooded sadist who has no problems murdering civilians to keep his cover and his actual purpose is to enforce the will of his superior Bando, a bureaucrat in the police force looking to get his hands on the Japanese retirement fund.
Like a Dragon: Infinite Wealth Ichigo gets arrested by a dirty cop after getting to Hawaii. Since he's a foreigner who barely speaks English and has no money or ID (due to having been robbed), the cop decides that he's just going to pin some unsolved crimes on Ichigo in order to get himself a promotion.
Mafia: The City of Lost Heaven: Don Morello had the whole Lost Heaven police department on his payroll. Until, He was killed by Tommy Angelo.
C-Sec officer Harkin, although he is fired from the force by the second game. Anderson mentions that the only reason he lasted as long as he did was because humanity wanted a presence in C-Sec and it would look bad if he was busted for one of his numerous crimes. By the sequel, there are enough humans working in C-Sec that it was no longer a concern, so he was sacked.
Captain Bailey is a deconstruction of this trope with a sympathetic POV. He's willing to take bribes from The Mafia... but only because it helps keep the peace and keeps his men alive. He authorizes rough interrogation of prisoners... but only because the crime rate in his district is awful and he feels the need to use extra force. He's also on Shepard's side for the most part and will bend the rules for him/her when he needs to.
Officer Kaira Sterling from the Noveria corporate police is openly taking bribes to cover up Administrator Anoleis' corruption and is more than willing to murder anyone who gets in the way.
Kaira: Do you know what we did to cop killers back on my world? Wrex: You're breaking the law for bribe money. Do you know what we do to dirty cops on my world?
Master Detective Archives: Rain Code: The Amaterasu Corporation Peacekeepers are a private security firm consisting of corrupt enforcers who abuse their authority to mastermind all kinds of crime and attempted murder and warp the truth to suit Amaterasu's interests. While the main Peacekeepers are already corrupt as is, Yomi Hellsmile, their leader and The Heavy of the story, takes it the extra mile by not only driving out any real detectives from Kanai Ward by executing them to save himself or persuading them into becoming part of his army, but also conducting a plot to manipulate the main detective agency's chief, Yakou Furio, into killing Amaterasu's head researcher, Dr. Huesca, for trying to escape Amaterasu.
B.B. from the first game turns out to be one of these, especially when it's learned that he killed Alex at the Roscoe Street Station and had Max framed for it.
The entire UFE in the third game is essentially the private army of the Big Bad and working with outlawed paramilitaries to abduct and organ-harvest the poor. Ironically, despite Rodrigo dismissing him as another of these, Da Silva is the only one we see onscreen who isn't.
Mirror's Edge: Standard procedure to arrest a Runner in the City of Glass seems to be "fill the fucker with lead, then Double Tap the twitching body". Even if you are doing a Pacifist Run and are clearly armed, they'll break out the heavy artillery and spray it at Faith even before actually ordering her to surrender! Subverted because you eventually find out that those armed men are Private Military Contractors, not cops.
In Mortal Kombat, it would really be wrong to say that Stryker is any worse than the other characters who are supposed to be good guys (all of them are willing to use lethal force). Still, his Battle Cry in the 2011 game is "Police brutality comin' up!" (Also, in that game, Stryker is unique in that he is the only character who appears to kill his opponent upon winning a match even if he does not successfully perform a Fatality; he throws a grenade offscreen, which results in an explosion, followed by a scream from the loser and a lot of blood.)
Doctor Peace in No More Heroes is a Dirty Cop, a Deadly Doctor, and a skilled assassin with many interests outside the law.
In Palworld, the fourth main boss Marcus is the leader of the City Guards and made a fortune selling drugs to the community, then arresting and fining his customers before confiscating his own product to sell again later. Despite not being the Final Boss he's the closest thing to a Big Bad the setting has as he's responsible for a lot of the islands' problems, including the corruption and hypocrisy of the Animal Wrongs Group Free Pal Alliance, the aforementioned drug epidemic, and the declining population. The Evil Poacher Rayne Syndicate is the only problem he's not provably involved with, although he's certainly not in any rush to deal with them either.
When you start off as a nobody in Pizza Tycoon, the police are pretty much straight edge. Once you have learned some street smarts and have some respect in the community, you'll be able to pay your way out of trouble and into the police's favors.
Any convict with the "Ex-Law Enforcement Officer" reputation and drug and/or corruption related convictions in Prison Architect is either this or a victim of Miscarriageof Justice.
Rave Heart: The SWAT and Galactic Enforcers are in on Count Vorakia Estuuban's plans to take over the galaxy of Xerxes, and are willing to cover up any evidence that might exonerate High King Arcturo. This doesn't seem to apply to all of them, since many of them join Ellemine's alliance once she takes back the Cosmic Cube and state that they were genuinely deceived by Vorakia's manipulations.
Agent Ross from Red Dead Redemption, whose hobbies include kidnapping people's families in order to force them to track down outlaws he should be tracking and murdering said people when they outlive their usefulness to him.
Red Dead Redemption II: Angelo Bronte's mob has the whole Saint Denis police department on their payroll.
In the first Resident Evil, there's a rather unusual example: Albert Wesker was the team captain of Division A of the S.T.A.R.S. Precinct and presumably also their leader, and seems outwardly to be a model cop. However, he is, in fact, a double agent for the Umbrella Corporation, and more importantly is intending to lure the S.T.A.R.S. Teams to their deaths at the hands of B.O.W.s both to silence them and to give the B.O.W.s battle data, and later games reveal that he was in fact also planning to betray Umbrella as well.
Resident Evil 2 has Police Chief Brian Irons, a wife-beater and serial rapist who is on Umbrella's payroll and thus not only works to conceal their wrong-doings but is also implied to discredit potential competitors and provide human test-subjects for them. He's also a lunatic who suffers a mental breakdown during the resultant Zombie Apocalypse, actively sabotages the efforts of his police to aid the human survivors, and finally takes to hunting them down and killing them himself. On top of all of that, the game also drops heavy hints that he may be a Serial Killer as well. And by hints, we mean the human skulls in his secret taxidermy chamber. Made worse in Resident Evil: Outbreak. One of the files in the first scenario notes that 8 blonde women, all ages 18-23, started disappearing and people were saying there were groans and screams in the sewers with the presence of Chloroform hinting that some of them were still conscious when he killed them. The description matches his last victim in RE2, the Mayor's daughter.
Saw II: Flesh & Blood: Jigsaw goes after a ring of corrupt cops who've been illicitly selling medical supplies like drugs, along with the doctors and nurses who set them up.
Scrapland: The police of Chimera are all kinds of corrupt. Regular police have the power to extort money from other robots, and they often engage in fights. Plus, there's the chief. He's a cheater, the Mayor's partner-in-crime, and will beat up anyone who tries to blackmail him.
In Shin Megami Tensei I, the police quickly align with the Demons by kidnapping innocents so a demon at the town hospital can experiment on them.
In Devil Survivor, after a few days in Tokyo after a lockdown resulting from demon presence, a group of police officers begins abusing the power of demon-summoning objects called COMPs to rob and/or kill others. They eventually surrender their powers after being beaten twice, the second time when faced with the lord of death, Yama.
In Persona 2: Eternal Punishment, several members of the Kounan Police Department (including its top leadership) are working for the evil government conspiracy.
The murderous Big Bad of Persona 4 is Detective Tohru Adachi, who only joined the force to get a gun and out of spite towards his parents, who kept pushing him through academics.
Persona 5: The cops who apprehend the protagonist drug and beat him to try and get information on his accomplices. In fact, the head of the Special Investigation Department in Tokyo is a member of The Conspiracy and plans to kill the protagonist and their friends to protect his illicit activities.
Normally, a big part of The Simpsons Hit & Run is the titular "Hit and Run" mechanic where, if you cause too much trouble or destruction, or run over too many pedestrians, the cops begin chasing you. Ignoring the fact that the cops cause just as much damage chasing you, will just try to run you over, and only fine you $50 no matter how bad you are, they also turn a blind eye to their own breaking the law. During one mission, and one mission only, you ride with Police Chief Wiggum on a mission: the Hit and Run meter is disabled for this one mission.
Skullgirls: The character Big Band was once a police officer by the name of Ben Birdland. Unfortunately, he was the only clean cop on the force, since his colleagues were all on the payroll of the Medici Mafia. One day, he was beat nearly to death by his colleagues (including one who was actually an anthropomorphic pig), which caused him to become what is essentially the lovechild of Inspector Gadget, RoboCop, an iron lung, and an entire orchestra.
Wei Shen, an undercover cop within the Sun On Yee Triad, is feared to be this by his superiors, who believe that he may go rogue and fully defect to the Triad. Given his belligerent attitude and his propensity for violent and illegal actions that often go beyond simply maintaining his cover (especially when It's Personal), these fears are well-founded. Subverted with the outcomes to Inspector Teng's investigations, the ending cutscene and the "Year of the Snake" DLC, which show that he really is a cop first, albeit a very reckless Cowboy Cop.
Played straight with Superintendent Pendrew, who built his career off of cooperating with the Sun On Yee's current Chairman and sent Wei in undercover to erase all evidence of his corruption from the inside out before his upcoming promotion to Interpol. Pendrew seems to believe in some version of I Did What I Had to Do; he has been offered a wide variety of goods and services, but never accepted anything from the Chairman other than information.
In the Prauge story, inspector Jiří Skalnic conceals evidence regarding the Prague murders in exchange for money from Ackerman's father. On top of that, he planned to have Gus take the fall for the ripper crimes.
In the Chicago story, FBI chief Todd Browning was a patron of the Red Lantern club and became nervous when Victoria's investigation turned towards the place and its clients. For that reason, he released Kolar even though they had incriminating evidence and rushed to close the Chicago Ripper case once Victoria shot the murderer, without making sure the killer is actually dead.
In Still Life 2, former FBI agent James Hawker shot an unarmed drug dealer during a stakeout, and was fired from the FBI. He also is revealed to be one of the people behind the Collective Identity of the East Coast Killer, using his knowledge to help David Karson construct an FBI-themed Death Course and luring the law enforcement to their hideout to be killed, to get revenge on them for firing him.
Part of the backstory of Streets of Rage is that the police have been taken over by The Syndicate. This leads to the three protagonists, who are police officers, quitting to take on the syndicate by themselves. The one remaining uncorrupted cop provides them with occasional backup in the form of a bazooka and a machinegun-equipped helicopter. The fourth game plays with this — the police are among the enemies you have to fight, but it's because you are inarguably causing massive amounts of trouble in the city. The cop enemies will actually attack the criminal enemies, and vice-versa. Late in the game, the heroes convince the police chief to help them, and the cops stop fighting you. That said, there's at least one cop enemy who never attacks criminals, only you, and the Commissioner is implied to be on the take.
In Streets of Rogue, you can bribe the police to make them ignore all crimes that you and your friends commit on that floor.
In Verdict: Guilty!, Sadu, the police trainer, is also the main source of illegal firearms to the underworld. Also, Mia is doing Mayor Sang's dirty work, though in her case her brother is being held hostage.
In Watch_Dogs, a pair of corrupt cops are seen providing protection for the Chicago South Club's slave auction, though they warn the mobsters that they won't be able to keep the "other boys" from busting the place if the event doesn't stay quiet. Later, after busting the auction yourself and hunting down its buyers one by one, the same cops provide an escort for the slave ring's leader as he tries to flee the city.
In Watch_Dogs 2, one of the sidequests deals with the SFPD using CtOS to organize drug deals with local street gangs.
