Yakuza is said to be a complex story set in the heart of the Japanese underworld, so jumping straight into the game without any prior knowledge of events might result in a less than full experience of the game.

With that in mind, SEGA has produced a 40-minute live-action short - a Yakuza prequel - for anyone to watch over at the official Yakuza website. The movie is split into four 10-mintute sections and part one is available to view now.

If you log into the site using your SEGA City account then you'll also be notified as and when the next part of the movie goes live.
