Lethal Weapon is the video game adaptation of the popular film with Mel Gibson. The game was created by Ocean and published in 1992 for the Amiga, Atari ST and MS-DOS.
Similarly to what they have done with Hudson Hawk, Ocean decided to make a 2D platformer/shooter, and the choice worked very well. Don't expect to find the plot of the movie, because the game just uses the license, but this is a very nice, and challenging, platform game.
