Vengeful over his parents' betrayals, with Heihachi being the one who never told him about Kazumi's assassinations on them before her death in the first place, Kazuya finally kills Heihachi in battle and throws his body into the volcano. Heihachi has the reporter escorted out back to Lars before traveling to a volcano for a final battle with Kazuya. Suspecting that Kazuya had inherited the Devil Gene, Heihachi threw him off a cliff, believing the boy's survival would confirm his fears. Heihachi recounts his love of Kazumi and the night he learned that she possessed the Devil Gene and was sent by her family to kill him, regretfully being forced to kill her in self-defense, which eventually marked the feud amongst the Mishima clansmen as of the present. The reporter uses this opportunity to inform the Zaibatsu about his exposé, but to his surprise, Heihachi offers to meet him in person. Kazuya survives the attack and destroys the satellite, with the wreckage destroying a town and once again slandering the Zaibatsu. He then captures and spreads images of a transformed Kazuya worldwide before using an orbital laser weapon to obliterate Millennium Tower. Heihachi survives, but declares himself dead to the public to continue his plans in secret. He defeats Heihachi after their temporary alliance on fending off an attack by an army of Jack-6's at the Mishima Dojo, and proceeds to G Corporation's Millennium Tower. The force sensed by Claudio is eventually revealed to be Akuma, who made a promise to Kazumi that he would kill Heihachi and Kazuya if she fails to, as she predicted both of them would engulf the world in war and destruction. Movement has undergone some changes and is similar to the movement mechanics found in Tekken Revolution, most notably when characters walk backwards. With a new display system, the game's multiplayer allows players to choose which side of the screen to play on. Unlike bound, however, Screw Attack cannot be used to do wall combos.

The bound system, which staggers a character to increase opportunity for additional hits, is replaced by Screw Attack, which makes the enemy spin sideways when they are hit airborne, allowing the player to inflict additional hits after they reach the ground. The mechanic also works for absorbing high and mid attacks. The second, Power Crush, lets the player continue their attacks even while being hit by the enemy, although they would still receive the damage dealt by the enemy's attacks. The first, Rage Art, allows the player to execute critical attacks that deal roughly 30% damage depending on the character once their health bar is critical, in exchange for inactivating the normal attack power increase.

Two mechanisms are introduced in the game.
