!!Common Tropes:

* AwesomeButImpractical: The games give you increasingly impressive bonuses for advancing through the ranks, with the ultimate one, for Commissioner, being 100 lives. Once you get that, you can keep playing until... well, you ''run out of time''. Worse, [[BraggingRightsReward you don't get any benefits whatsoever once you reach Commissioner]], meaning that once the clock runs down, you're sunk. And needless to say, if you continue, your lives get reset to 3. Unless you're a real ace at this game to the point where time isn't an issue, it's much better to pick up the first two bonuses (5 seconds and 10 seconds, respectively) and then [[DoWellButNotPerfect die on purpose]] to reset them, tacking on the third bonus (1 life) only when you're on your last life.
* BigBad: Katsuji Haraguchi is the leader of Gokudou-kai in the first game. In the second game, [[DragonAscendant Shigenobu Matsuyama becomes the new leader.]]
* BigBadDuumvirate: Shigenobu Matsuyama and Hung Ko Cheung in the second game.
* CensorBox: The eyes of criminals in their portraits are censored out, not unlike in Japanese television broadcasts. When you fight them, their faces are pixellated.
* DarkerAndEdgier: To the first two ''Lethal Enforcers'' games.
* DualBoss: Bai Ei Lee and Noriko Nagata in the Japanese version of the first ''Police 911'' game.
* DynamicDifficulty: The game's extremely fast, with [[CatAndMouseBoss bosses running and shooting around]]. Players have to aim more precisely in order to defeat the boss.
* HighSpeedBattle: You need to TakeCover and return fire in a quick succession in a limited time to avoid getting hit by enemy gunfire. Also, all bosses, despite being CatAndMouseBoss, runs at fast movements.
* HostageSpiritLink: You don't actually die, you just get treated to a time-wasting cutscene, and you lose a few ranks. The same applies to ''Lethal Enforcers 3'', in which it shows a news headline reading "[occupation of civilian] shot by mistake."
* InfiniteOneUps: Reaching the highest rank is no easy feat, as deaths and [[HostageSpiritLink shooting civilians]] will demote you. But if you can pull it off, you'll get a 100-life bonus as a reward. However it is not a guaranteed win, because you can still get a GameOver by [[TimedMission running out of time]].
* OddlyNamedSequel2ElectricBoogaloo: It was intended to be a separate game series, before ''Lethal Enforcers 3'' arrives.
* PainfullySlowProjectile: Bullets are so slow you can easily follow their trajectories. It helps, because the series is still NintendoHard even with these slow bullets.
* ShoutOut: The bosses are named after the staff members of Konami.
* SongsInTheKeyOfPanic: If the player either loses a life, shot an officer or a civilian, or is down to their last life, more distressing music plays.
* TakeCover: The series is an expansion of this idea, using ''motion sensors'' instead of a foot pedal.
* TechDemoGame: One of two games produced to show off the use of motion-capture technology in an arcade environment, the other being ''Mocap Boxing''.
* VideoGameCrueltyPunishment: Shooting innocents in the Japanese version will lose you a life as well as your rank.
* VideoGameLives: The game gives you ''one hundred'' more extra lives above your starting three if you reach the top rank of Comissioner - but since the process of losing a life and restarting takes about 15 seconds of your rarely more than 2 minute timer (the game ends instantly if the timer runs out) this is solely a BraggingRightsReward. And if you die on your way to Commissioner rank, you lose every promotion and have to start over.
