Last night I finished watching "Streetfighter assassin's fist" . I enjoyed it, even though I don't know the game the film was based on. Two guys were training at a dojo and there was some mystical aspect to their training. The film was part in English and part in Japanese. But there was no subtitles for fairly long sections of the film.
It was a strange film, because it looked to be part of a miniseries. Now that I do a web search I see that is released as a web series first.
The martial arts was basic kick boxng with some meditation throw in.
The film streetfighter with Sonny Chiba is more interesting, because it seems based on old school Karate or Kenpo.
