A hitman slides through the rain as neon lights reflect on slick streets. A figure in the shadows whirls around, baring his face for a second, only to return to the shroud of darkness. In this game, the contenders have a different regard for the killer's code. First up is O, reclusive by nature and sharply disciplined, detached from people and emotion. Next up and eager to slide into the top spot is the flamboyant and reckless Lok, who lives in a fast-paced and glamorous world. With methods patterned after his action movie icons, he relishes the thrill of the hunt. An Interpol Police Inspector is on their respective trails, but Lok manages to lure O out of the shadows and into an ultimate duel where only one man can come out alive.
