Crime Fighters

Crime Fighters is a 1989 Beat Em Up made by Konami, released around the same year as their Teenage Mutant Ninja Turtles arcade game. Up to four players (or two, depending on machine settings) try to rescue a huge group of girls kidnapped by a crime lord. This game was known for its very risque sense of humor, one of the main reasons why this game never got ported to home systems.

It has a sequel named Crime Fighters, known as Vendetta in non Japanese territories. Violent Storm is mistakenly labeled as the third game in the series, despite being completely different from the two.

This game contains examples of:
 * Angry Guard Dog: Appears in the late levels.
 * Anticlimax Boss: The mob leader who gets out and throws a key to the cell.
 * Boss Rush: After beating the game for the first time, you fight all of the bosses at once again in a Bonus Level of Hell along with a few enemies.
 * Captain Ersatz: Some of the bosses. In particular, The second stage boss is reminiscent of Jason Vorhees, the fourth stage boss is based on Leatherface and the 5th stage boss is based on Freddy Kruger.
 * Color Coded Multiplayer
 * In the 2-Player version:
 * Difficulty By Region: An odd example. The Japanese and European versions of the game were two-players and they have lives and a life bar. The American four-player version removed the lives and gave you Hit Points (100 per coin) for every token you inserted in, and worse, it drained your life by 1 point about every 10 seconds. The Japanese version also has a back kick button that was removed in the American version.
 * Do Not Drop Your Weapon: Played straight with the enemies, but you lose any weapons you pick up as soon as you're hit.
 * Groin Attack: Can be done to you or the enemies.
 * Hitbox Dissonance: You'll have a hard time trying to hit enemies in this game. The bosses are even worse, as they'll most likely hit you before you hit them.
 * Macho Camp: These enemies are only found in the Japanese versions of the game. There's also dog enemies that try to hump you. They would return in the Japanese version of Vendetta.
 * Palette Swap: All four player characters.
 * Ratchet Scrolling
