The legendary series was introduced in arcades by Technos Japan in 1987 with the first 16-bit version Return of Double Dragon, originally released in 1992. Billy and Jimmy Lee are young twin brothers who run a martial arts dojo. After their friend Marian disappears, the Lee brothers fight to rescue her. 1 to 2 players control the Lee brothers, masters of the Sousetsuken martial art. A fierce battle with the Shadow Warriors unfolds over 7 stages, including extra stages not found in the original US version. In contrast to previous entries and arcade versions, the Lee brothers arsenal of moves has increased dramatically! The player can perform over 30 special moves! Many of these moves did not exist in the original US version.
The storyline doesn’t follow the continuity set by the first three games. Instead, it’s more or less a remake of the original arcade game. It seems that Billy and Jimmy Lee have opened a new martial arts school in town and have quickly gathered popularity. The other dojo in town, the Duke Dojo (secretly operated by the Shadow Warriors), isn’t too happy about this. The bad guys kidnap a female cop named Marian Kelly, who is one of the Lee brothers’ students, and will only release her in exchange for the Sou-Setsu-Ken Dojo. So now it’s up to the Lee brothers to save the girl and beat up the bad guys.
