Tekken 7 was announced at this years EVO tournament (actually it leaked just before the announcement) and with it came the promise of new details at Comic-Con. Well here's the details! For the story it's going to have a detailed background story that focuses on the conclusion of the Mishima clan saga.
The game will apparently answer why Heihachi is trying to kill his grandson, why Hiehachi threw Kazuya off of a cliff, who Devil Jin is and other Tekken mysteries.
You're probably sold right there, but let's move on. They're working on the details for the game of course, but it's all one-on-one fighting. Interestingly enough though they're bringing in seven guest artists to do character designs including:
Mari Shimazaki (Bayonetta), Yusuke Kozaki (Fire Emblem Awakening, No More Heroes), Ninnin (Duel Masters, Cardfight!! Vanguard) and Kenichiro Yoshimura (Max Anarchy/Anarchy Reigns)
That's actually quite unusual, but could prove to be very cool!
