This mod changes many aspects of the game to give it more movie-like feel, and make the gameplay more intense. Weapons were significantly changed, player classes changed and redefined. New player classes are present, and new music, skins, sounds and characteres are introduced. Most of the sounds come from the movies and AvP Gold, but there are also a few sounds from Soldier of Fortune. For an extensive info see the mod's homepage.
