Code of the Assassins (aka Song of the Assassins)

A distinguished young assassin, trained by the best, receives his first assignment for a secret society of assassins. Failing to complete his mission, he becomes a fugitive hunted by the government, shadowy figures and rival assassin groups. With his weaponized mechanical hand, he must survive double crosses, gadget-arsenal armed killers and clashing factions to find a secret treasure map and get to the bottom of the huge conspiracy he finds himself tangled in.
