Tekken 6: Bloodline Rebellion is the update to Tekken 6. It features new characters, stages, items and customization options. It also gives the game a balance update from characters and items. It is was released to Japanese arcades in December 2008, and is slated for an October 2009 release for the PlayStation 3 and the Xbox 360. It is also currently shown as a demo in the Namco-Bandai AM SHOW.
Though the storyline for Tekken 6 has yet to be translated, fan-based translations and gameplay trailers have revealed that Jin Kazama was the canon winner of the King of Iron Fist Tournament 5, and for unknown reasons has begun using the Mishima Zaibatsu for world conquest, declaring war on several nations and even space colonies until the entire world is at war.
Meanwhile, Kazuya Mishima has discovered the division of G Corporation that tried to kill him, and takes his revenge by murdering them all. Kazuya then takes control of G Corporation and uses it as the only power in the world to counter the Mishima Zaibatsu. By this time, the world sees G Corporation as its only saviour and Kazuya is viewed as a hero, although his true intentions are to kill Jin and steal his part of the Devil Gene to stop him interfering with his own plans for world domination. Using G Corporation's newfound popularity to his advantage, Kazuya puts a bounty on Jin's head, dead or alive. Furthermore, Heihachi Mishima, father of Kazuya and grandfather of Jin, seeks to reclaim his Zaibatsu, having been unconscious throughout the King of Iron Fist Tournament 5. Jin, having anticipated this, announces the King of Iron Fist Tournament 6 to rid himself of Kazuya and his other enemies once and for all.
This new version will feature two new characters: Alisa Boskonovitch, a cyborg with jet wings and spinning limbs who may be the cybernetically - enhanced daughter of Doctor Boskonovitch; and Lars Alexanderson, an unknown descendant of Heihachi Mishima. A number of new items and customization options were showcased in the trailer. There will also be all-new CG character art, just as there was a change in art from Tekken 5 to Tekken 5 Dark Resurrection. Upgrade kits will also be available for owners of current Tekken 6 machines.
Actually, I already played this update at Trinoma. All I can say is that it's more fluid and easy when it comes to controls. The CGI have improved a bit, and the pre-fight animation of all the characters were changed just like in Dark Resurrection. The only down side is the occasional lags that occur when using a data card.
I guess we just have to wait for the definitive PS3 version of the game in order to give a precise review of the game.
