This isn’t the Double Dragon II you remember. Double Dragon II: Wanderer of the Dragons is a 3D beat ’em up that takes Billy and Jimmy Lee through the Wild West. The game also turns Marian, the Lee’s girlfriend in Double Dragon, into a playable character. I think she’s supposed to be some kind of ninja.
After Technos folded, their intellectual property transferred over to Million. Double Dragon II: Wander of the Dragons is made by Baruson Creative, a Korean company behind the Xbox 360 karaoke game Superstar and "weapon papa" DS game Iron Master. They also handled localization work for a number of Atlus titles including Shin Megami Tensei: Devil Survivor.
