Quite an interesting plugin that adds a laser sight from GTA Vice City to GTA III. The trick of the mod is that the sight is added not only to the Sniper Rifle, but also to the M16 and the Rocket Launcher. The Archive contains an .ini file that allows you to: edit colors, make new crowns for the laser, remove the dot, etc. The plugin supports all versions of GTA 3. Also in the archive there is a ReadMe from the Author completely in Russian.
Installation: Throw everything in the folder with the game.
