The mysterious G Corporation conducts a full-scale attack on the building that Heihachi and Kazuya Mishima were in during the climactic sequence of the last game. The episode includes military helicopters and combat cyborgs. Heihachi is presumed to have been put to death, while Kazuya betrays his father and makes his escape. Despite this, the Mishima Zaibatsu continues to do business as usual, albeit its leaders remain a mystery. When it was announced that the fifth King of the Iron Fist competition would be held, Kazuya and his son Jin decided to participate in unraveling the riddle.
Tekken 5 is a fighting game that is more similar to past iterations of the series due to reducing the odd stage design characteristics introduced in its immediate predecessor. Five new characters have been added to the ever-expanding regular cast, and all of the unique modes from the previous games have been brought back, along with the addition of a combat minigame and a platforming game called “Devil Within,” which star Jin Kazama in their own separate stories. The opportunity to personalize the characters by giving them different colored garments, additional costumes, and things that can be bought with money earned from the battles and then equipped is something else that is brand new to the franchise.
