Lethal Weapons was released for various home computers, the NES, Super Nintendo and Game Boy in 1992. It was actually based on the movie Lethal Weapon 3 which was the iteration of that series that was released around the same time. The game is a fairly typical side-scrolling platform adventure game with the quality you have come to expect from licensed properties.
There are two primary versions of the game. One released for the NES and Game Boy and another released for the Super Nintendo and various home computers. In both versions, you get to choose to play either of the two main protagonists, Riggs or Murtaugh. The NES and Game Boy version is extremely difficult and mostly involves fighting with various criminals in the Los Angeles area. You can either punch or shoot your enemies. The Super Nintendo and computer versions are similar types of games but the levels have more specific goals. The difference between the two characters that you can choose from are minimal and relate to firing speed and jump height.
None of the versions are particularly great games. The computer versions seem to be more highly regarded but that's not saying much. If you do want to give this one a try, the Amiga (or Atari ST) version is probably best. Pick the SNES version over the NES or Game Boy version if you want a console game but if you are a sucker for punishment and want to play both variations then you'll have to give the NES version a shot too. Needless to say, this game has never been re-released. A Sega Master System version was planned and may have even been mostly completed but was never released.
