Double Dragon II: The Revenge

Double Dragon II: The Revenge is a beat 'em up video game for the NES where players control Billy and Jimmy Lee on a mission to avenge the murder of Billy's girlfriend, Marian, at the hands of the Shadow Warriors. The game is a sequel to Double Dragon and features cooperative two-player action, nine distinct missions, and multiple difficulty levels, though the hardest setting is required to play all nine stages. The story, gameplay, and level design differ significantly from the original arcade version, introducing new enemies and a new final boss.
