A year later, the game received an update, subtitled Bloodline Rebellion; both versions also saw a limited release in North America.

A home version based on the update was released for the PlayStation 3 and Xbox 360 in October 2009; this was the first time a main installment was produced for a non-Sony console.

He replaced the longtime producer Hajime Nakatani from the first game, where Harada started out as a voice and a part of the original development team.

[4] While this version retains elements from the earlier games, Tekken 6 introduces a new Rage system that increases the strength of the player characters when their health gets low.

Losing his memory in an attack against Jin Kazama's Mishima Zaibatsu special forces, Lars goes on a journey with a robot named Alisa Bosconovitch to learn his identity, so that he will be able to recover the subject of his mission.

In this campaign mode, the player can win items by completing missions and enhance different power areas of any characters they choose to control.

Tekken 6 features bigger stages with more interactivity than its predecessors,[5] including walls or floors that can be broken to reveal new fighting areas.

Players can also pick up weapons like poles and Gatling guns, along with lootable items, money, and power-ups which can be found inside crates that are scattered throughout the playing environment.

Players can move freely between fights, but when a group of enemies is encountered, the gameplay switches to the traditional, two-dimensional Tekken style.

This mode originally included offline single player only, but on January 18, 2010, Namco released a patch that allows online co-op for the Scenario Campaign.

As the war continues to erupt, the field leader of Mishima Zaibatsu's Tekken Force, Lars Alexandersson, has rebelled from the army along with several of his soldiers.

Accompanied by an android, Alisa Bosconovitch, Lars ventures throughout the world, avoiding the Mishima Zaibatsu's manhunt for him while also trying to recover his past.

[14][15] After coming into contact with several allies, including his adoptive brother, Lee Chaolan, Lars confronts the G Corporation and Mishima Zaibatsu's headquarters.

Following his defeat, Jin admits that his reason for launching the war was to awaken Azazel as it can only take a physical form through the negative energies of the world, and destroy him.

Response to the original arcade game was highly positive, but Harada said the team aimed to make more improvements to attract new players.

Like some games in the Mortal Kombat series, Tekken 6 is notable for adding the element that allows players to throw enemies down to another area of the stage.

[37] On October 23, 2009, Namco Bandai released a Tekken 6 themed Game Space on the North American version of PlayStation Home.

[42] Unlike other new Tekken 6 characters who were based on fan input, both Lars and Alisa were created using a different approach, focusing on their importance to the game's story.

[43][44][45] Outfits for Anna Williams and Asuka Kazama were made by Mamoru Nagano, and Ito Ogure did one for Lili Rochefort.

[47] Although the scenario campaign was removed from the PlayStation Portable's port, the developers added background information for the characters in the arcade mode.

[48] Makoto Iwai, chief operating officer of Namco Bandai, said the developers tried to make the PlayStation Portable contain as much content as the original console versions.

[53] The cast also includes in-house composers Rio Hamamoto, Ryuichi Takada, Yoshihito Yano, Go Shiina, Akitaka Tohyama, and Keiki Kobayashi, as well as Kazuhiro Nakamura, Satoru Kōsaki, Keigo Hoashi, and Kakeru Ishihama from Okabe's company Monaca, and Shinji Hosoe and Ayako Saso of SuperSweep.

Music for the scenario campaign cutscenes was handled by Hitoshi Sakimoto (who had previously composed for Tekken Advance), along with other composers at his company Basiscape, including Masaharu Iwata, Yoshimi Kudo, Noriyuki Kamikura, Azusa Chiba, Kimihiro Abe, and Mitsuhiro Kaneda, with its compositions being performed by the Czech Film Orchestra.

[53] The PSP version features additional music composed by Tohyama, Tetsuya Uchida, Yano and Junichi Nakatsuru.

[68][8][76] The game's Scenario Campaign mode was subject to mixed criticism as well for citing bland environments and repetitive enemies.

[61] IGN said the portable version had greatly improved loading times compared to its console counterparts,[71][69] while others enjoyed it despite lacking the Scenario Campaign and retaining the same graphics.

[90] For this game, Lars was given an alternate design created by manga author Masashi Kishimoto, famous for writing the series Naruto.

As a result, Matsuyama approached Tekken 6 producer Suguru Sasaki and his team and asked them to allow him to include Lars in the game using Kishimoto's outfit.

Once this was approved, the Tekken staff began assisting CyberConnect2 to adjust Lars' moves to fit the other characters in the Naruto game.

[91] The first CGI scene from the game also influenced the developers to create a film titled Tekken: Blood Vengeance which uses this type of animation.
