Crime Fighter

Crime Fighter is a 1989 side-scrolling beat-em-up released by Konami for the arcades. The player takes control of an undercover police officer who is assigned to rescue a group of kidnapped girls from a crime boss. In the four-player versions, each player position has its own coin slot and each credit value adds around a hundred health points to that position which slowly drains one health point per tick (similar to Gauntlet). Players are able to accidentally hit each other and cause allies to drop their weapons permanently. After defeating the boss at the end of each level, if the game has more than one current player then the players are given a time limit that refreshes when a player is hurt and tells the players to fight as long as they want and lose health. While some health is granted at the end of the time limit, it is possible to lose more health than granted during this fight. The two-player version gives players a set amount of lives and the health/timer system is replaced with a standard life meter and life counter similar to Double Dragon.
