Lethal Enforcers (リーサルエンフォーサーズ Rīsaru Enfōsāzu) is a 1992 shooting game released for the arcades by Konami. It is best known for its revolver-shaped light gun known as the Konami Justifier, its digitized graphics, and the controversy over its content.
Home versions were released for the Super NES, Sega Genesis and Sega CD during the following year. The home versions makes use of a revolver-shaped light gun known as the Konami Justifier, which came packaged with the game. A standard controller can be also used in lieu of the light gun in these versions. A second-player Justifier light gun, pink in color, was available only by mail order from Konami, and is very hard to find today.
Lethal Enforcers was followed by Lethal Enforcers II: Gunfighters. The Japanese arcade game Seigi No Hero was localized to Western markets as Lethal Enforcers 3. The game is also featured alongside Lethal Enforcers II in the two-in-one compilation titled: Lethal Enforcers I & II (Lethal Enforcers Deluxe Pack in Japan), released for the PlayStation in 1997.
