Germany’s USK rating system recently registered and rated Double Dragon II: Wanderer Of The Dragon’s Cyclone for Xbox 360. The port, as of yet, is still technically unannounced. Weirdly the port is not being produced by Million, a company made of ex-Technos employees, who own the intellectual property of Double Dragon II. Korean developer Barunson Creative is, however, listed as the publisher.
Thanks to Siliconera for the info.
