Despite dozens of chopper slashings and a fairly disturbing rape scene, the Category III rating here probably came more into play due to Rules of the Game's usage of Triad rituals, which are displayed as the veteran Shing (Alex Fong) inducts the hot-headed David (Louis Koo) into the Hong Kong underworld. The usual "rags-to-riches" Triad story follows its' embedded cinematic roadmap, having David quickly rising up the ranks, which leads to a bloody confrontation during the finale, where characters drop off left and right, with no real resolution given to the story.
