Tekken 6 has had little revealed about it for some time. First, we saw that the E3 promotional video 2 years ago. Then, we see the E3 video last year. Later, it was revealed that that wasn't Tekken 6 per say, but rather how Tekken would possibly look on the Ps3. However, in February, at the AOS in Japan, Tekken 6 was finally displayed, confirming what we should expect from it. In that demo, two new characters were revealed and several characters were confirmed to return. The two new characters are Zafina, a female fighter who, in the creator's word, uses moves that are likened to a Spider; and Leo, another female fighter who uses Bajiquan, a style that was made more famous by Virtua Fighter's Akira Yuki. Another new thing revealed was the apparent ability for some characters to use items. Shown in the demo was Bryan Fury using a Shotgun to finish a juggle combo.
Recently, around a month ago, the storyline and some character profiles were revealed.
Storyline:
The story takes up from the end of Tekken 5, with Jin Kazama proving to be the victor. Now, as the head of the Mishima Zaibatsu, he uses his new power to spread propaganda and to play world powers against each other. Later, the Mishima Zaibatsu declares itself as its own, independent country and world power. However, shortly after this, G Corporation puts a price on Jin Kazama's head. Jin then announces the King of Iron Fist Tournament 6.
Pretty interesting storyline, especially with the profiles that were revealed.
Profiles: (Will be updated)
Leo: Her mother was killed by a mysterious person in G Corp. After this, he enters the King of Iron Fist Tournament 6.
Zafina: In her village, it is said that when two evil stars collide, the world will end. She enters the tournament to see if the world will end.
Yoshimitsu: His sword is a cursed blade that gains power from killing those with evil hearts. The sword has extremely weakened over time, so he must find a new sword to quell the sword he uses now. Now, with two swords equipped, he enters the 6th King of Iron Fist Tournament.
Heihachi Mishima: He finally awakes after the Jack ambush back at the 4th Tournament. After he awakes, he finds out that Jin is now the head of the Mishima Zaibatsu. Enraged, he enters the 6th Tournament.
Jin Kazama: Pretty much the main storyline.
Kazuya Mishima: He rose to power in the shadows of G Corporation, killing the ones responsible for the assault on Honmaru (One of them is Leo's Mother). Eventually, he becomes the head of the G Corp. Seeing Jin Kazama as a possible threat, he puts a price on his head for anyone to kill him. Later, he enters the 6th Tournament, intent on killing Jin and unifying G Corporation and the Mishima Zaibatsu.
Interesting storylines, especially with Kazuya and Jin. Later, it was revealed that when Tekken 6 was shown in February, it was around 40% complete. The creator discussed new changes to several characters. First off, every character will have at least one item move, each one having a different effect. Secondly, he said that Yoshimitsu's fighting style will be adjusted to fit with his two swords, mixing that in with hand-to-hand combat to tie into his story. He also said that Law will receive modifications that will make any Bruce Lee fan or practitioner of Jeet Kune Do happy, meaning major changes are going to be made to him. Lastly, it was stated that Lei Wulong's stance transitions will be different from before, being more comparable to Lei Fei's or Shun Di's from VF.
Screen shots:
Here is a link to a group of screen shots for Tekken 6: http://www.tekkenzaibatsu.com/tekken6/_arcscreens.php?gid=t5arc&pagenumber=1 I must say that the screens are impressive to say the least. The detailing actually looks a bit better than VF5! Overall, I can't wait for Tekken 6's release later this year or next year.
