Tekken 4 is the fifth installment in the Tekken video game franchise, and was the second in the Tekken series for the PlayStation 2. Developed and published by Namco, it was released as an arcade game in 2001 and on the PlayStation 2 in 2002.
GameplayTekken 4 introduced significant new gameplay changes from the previous games in the series. For the first time, it allowed players to maneuver around an arena interacting with walls and other obstacles for extra damage. These "environmental hazards" in turn allowed players to juggle opponents for consecutive combos and allowed the designers to implement a "switch maneuver", which let players escape from cornering and throw the tide in their favor. Also, the game engine had been tweaked to be more focused on the environment, causing the characters to move more slowly and fluidly than in Tekken Tag Tournament. Finally, the game introduced a brand new graphics system, that featured increased lighting, dynamic physics, and smoother surfaces.
In high level tournament play, it became apparent that the engine changes caused the game to heavily favor quick jabs and punches, upsetting some fans due to the decline in usefulness of more complex moves and strategies. Jin Kazama especially, was very over-powered, and if one were to look at the tournament records, he was used by nearly every top player.
Tekken 4 includes a Beat em' up mini-game available from the outset called Tekken Force. Similar to the previous minigame found in Tekken 3, it presents the player with an over-the-shoulder perspective as they fight wave upon wave of Heihachi's Tekken force through four stages, eventually facing Heihachi himself. The player can pick up health and power-ups while they fight waves of enemies. In the mini-game it is discovered that the Tekken Force possesses different ranks in the organization, evident in different amounts of stamina, strength and skill.
Not willing to give up, Heihachi ordered his researchers to collect blood samples, skin tissue, and hoof fragments left behind by Ogre (or known as True Ogre in its true manifestation) in order to conduct genetic experiments. Heihachi’s goal was to create a new life form by splicing Ogre’s genome with his own. However, the research was unsuccessful.
After extensive experimentation, Heihachi’s bioengineers came to the conclusion that an additional gene - the "Devil Gene" - was necessary in order to successfully splice Ogre’s genetic code into another living organism. Heihachi learned that his own genome lacked the Devil Gene, but he knew someone who had it... Jin Kazama.
Jin, who vanquished Ogre in The King of Iron Fist Tournament 3, was shot and mortally wounded by Heihachi. As his life slipped away, Jin transformed into a Devil. Upon his transformation, he struck down Heihachi and took flight. Jin’s whereabouts were unknown after the Tournament.
Heihachi searched for Jin to no avail. However, Heihachi discovered a photograph during his investigation that stirred his curiosity. The 20-year-old photograph was an image of a burnt corpse covered with laceration wounds. Heihachi paid particular attention to the corpse’s back, which had what looked like deformed, protruding wing-like limbs.
Convinced that the picture was of Kazuya, his own son whom he threw into a volcano 20 years ago in 1987, Heihachi diverted all his resources into a search for the body. This search eventually led Heihachi to G Corporation, a cutting-edge biotech firm making unprecedented advances in the field of biogenetics research.
Heihachi discovered that G Corporation found the corpse and extracted and analyzed its genetic data. In fact, Heihachi learned that the company was in the midst of creating a new life form by using the data. Heihachi also determined that Kazuya’s remains and research data were secured at G Corporation’s Nebraska and Nepal research laboratories, respectively.
Thursday, 25 December 2007. The Tekken Force raided G Corporation’s maximum security research laboratory in Nepal. The bottom floors of the building were obliterated, and the remaining data storage facility containing file servers was airlifted by a group of heavy-duty helicopters.
At the same time, a separate unit led by Heihachi infiltrated the underground research facility in Nebraska, where Kazuya’s remains were preserved. As Heihachi observed from his helicopter, he soon realized that unlike the Nepal facility, the operations in Nebraska were not going according to plan. The tactical status monitor screens showed the first wave of the Tekken Force troops being blown out from the storage room where Kazuya’s remains were supposedly kept.
A silhouette of a large figure slowly emerged from the room. When Heihachi could see clearly enough, he instantly recognized the large figure as Kazuya.
Kazuya was resurrected in G Corporation’s research facility. After his resurrection, Kazuya offered his body as research material to determine the true nature of the Devil that resided within him. Kazuya’s goal was to unify his two selves into one. Kazuya theorized that if he unified his body with the Devil, he would be able to truly harness its powers. He could then finally take revenge against Heihachi and the Mishima Zaibatsu (Financial Empire).
Enraged that Heihachi thwarted his plans, Kazuya obliterated the heavily armed Tekken Force and vanished into the flames of the lab’s wreckage. Heihachi was infuriated by Kazuya’s escape and took out his anger on his hapless subordinates who reported the escape.
Doctor Abel, Heihachi’s lead scientific advisor, urged the enraged Heihachi to quickly find a way to capture Kazuya. Once his anger subsided, Heihachi focused his mind and decided on a plan. An evil smile crept upon his lips.
Two years had passed since The King of Iron Fist Tournament 3. The Mishima Zaibatsu announced The King of Iron Fist Tournament 4 and placed the massive financial empire as the top prize. The champion who manages to defeat Heihachi at the end of the Tournament would inherit the Mishima Zaibatsu.
Well aware that the tournament is just a trap designed to lure him out, Kazuya nevertheless enters - it is his chance to defeat Heihachi.
After defeating so many opponents, Kazuya arrives at stage 7 to face his son, Jin Kazama, who ever since the ending of the Thrid Tournament, had a grudge against the Mishima. After training in traditional karate for the last 2 years, Jin was finally ready to destroy the zaibatsu, and put an end to the cursed Mishima bloodline. However, he was captured and taken to Hon-Maru, while others reported Kazuya as the default winner. Although sensing Heihachi's interferance with Jin's disappearance, he proceeded to the final stage.
When Kazuya met Heihachi, he asked what he did to Jin, with Heihachi saying that he would tell him after the fight. Pulling out all the stops, Heihachi was victorious. However, he did not kill Kazuya outright. "Come with me if you wish to see your son." A few hours later, Kazuya and Heihachi finally arrived at Hon-Maru. Seeing his son for the first time, Devil suddenly took over. "So, you were with him after all, my half." Hearing those words come out of Kazuya's mouth, Heihachi asked "Who are you?" with Devil replying "I am what you refer to as 'Devil'. 20 years ago I lost a part of my self when you nearly killed me."
He then proceeded to knock Heihachi out of the room, and take Jin's devil out. However, it ended in failure, and Kazuya once again regained control. "I see." he mutters. "I did not know the method of unifying our powers." He then taunted Jin to rise, which Jin did. When Jin finally frees himself, he starts to have final thoughts. "You! If only you were dead. Once I kill you, it'll all be over!" suddenly an enraged Jin fights and nearly kills Kazuya. When Kazuya is defeated, Heihachi once again walks over to his limp body.
"What a pathetic wretch, you worthless coward." He then proceeded to kill Jin and take his Devil Gene for himself. However, Heihachi was also defeated by Jin. As Jin morphed into his Devil form, he proceeded to deliver the final blow and kill Heihachi, once and for all. However, a bright light overwhelmed Jin, and as he saw a spiritual guidance of his mother, Jun Kazama, he let Heihachi go. "Thank my mother, Jun Kazama," he told Heihachi, and once again, he flew off into the night, leaving no sign of danger anywhere.

- Speculation suggested that Devil Kazuya was unlocked when beating Tekken Force in Ultra Hard difficulty, this is however fake since the game lacks motion for Devil Kazuya as well as a control scheme to be able to use him.
- This game, and Tekken Advance, notably lacks a "demonic" Final Boss unlike all the other major releases.
- Due to the lack of characters (less than Tekken 3), "demonic" Final Boss and bonuses, the game could be considered a "test game" so that developers could play around with features and graphics to see players reaction to them.
- This is the only canon Tekken game that Paul's defult costumes are not his red gi or motorcycle oufit
