Welcome to Hong Kong, a vibrant neon city teeming with life, whose exotic locations and busy streets hide one of the most powerful and dangerous criminal organizations in the world: the Triads. You play the role of Wei Shen, an undercover cop trying to take down the Triads from the inside out. You'll have to prove yourself worthy as you fight your way up the organization, taking part in brutal criminal activities without blowing your cover. Torn between your loyalty to the badge and a criminal code of honor, you will risk everything as the lines between truth, loyalty and justice become permanently blurred.
