Axel Stone and Blaze Fielding, now living quiet lives outside the metropolis, are drawn back into the fray after discovering a photo of their captured friend and realizing the police force has been compromised from within. With their former allies either dismissed or reassigned, the pair must rely on Adam's younger brother Skate and Axel's friend Max as they battle through waves of street thugs, organized gangs, and specially trained fighters to reach Mr. X and save Adam before the Syndicate's grip becomes absolute.
