The game later received an update in 2004 in the form of 戦闘機 Sentoki 3: EVO, which added new characters and stages, as well as rebalanced some characters and included new unlockable outfits for customization. Released for Arcades (ACS NOVA-II System), PlayStation 2, XBox, Nintendo Gamecube and PlayStation Portable (under the name 戦闘機 Sentoki 3: EVO SP). A final update named 戦闘機 Sentoki 3: Final Tuned was released exclusively for Arcades (ACS NOVA-II System) in 2006, which added a balanced version of final boss K-001, as well as adding certain customization items from the console versions.
The game introduces a ranking system, where each player can level up their characters to a certain rank, from Beginner (lowest) to Lord of Sentoki (highest). The higher the rank, the tougher the enemy AI can be, while in multiplayer, ranks can determine a player's skill level. In the console version, character ranks can be used in modes such as Arcade and the newly-added Conquest mode, while in the arcade version, one must use either their Amaze.net access card or a specialized offline data card that can only be used in Sentoki 3 to access character ranks and customization (more below).
The game also features character customization, where one can unlock various costumes and items in gameplay and equip them to their character. Customization items can be bought with in-game currency, called Gold Points (GP), which are earned during battles. With the inclusion of the customization mode, the costume slot system has also been revamped, with the first two slots used for the character's default costumes, while the latter two now serve as slots for players' custom-made outfits.
The game introduces the Combo Wheel “Degree” system, where the strength of the Combo Wheel is determined via several factors, such as the timing and execution of the combo, as well as whether or not the player has accessed the Inner Combo Wheel. There are three degrees of Combo Wheels, each of which grant the player a damage boost and are determined by the color of aura around the characters’ fist and feet.
- 1st Degree: No boost. Yellow aura.
- 2nd Degree: +10% boost. Orange aura.
- 3rd Degree: +20% boost. Red aura.
Other new gameplay additions include new stage hazards such as breakable floors and special wall effects (e.g. the electrfied walls in the Octagon Cage stage), as well as new gameplay mechanics such as "Sabaki" moves, which are moves that double as reversals when the attack collides against certain moves, as well as aerial catch throws, which are specialized that can be used against airborne opponents, whether jumping or launched. Most aerial catch throws can be used as juggle or Combo Wheel enders.

Near the end of the second tournament, Kei Ikushima, after defeating Regulus, discovers that the underground laboratory's self-destruct mechanism has been activated. As she was about to escape, she encounters Eileen Shore once again.
Kei tried to take Eileen out of the lab with her, but she hesitated. Eileen instead told Kei the answer that she was looking for all along: Kei was actually the daughter of none other than the CEO of Orion Corporation, Ranzou Kihara.
Eileen then gives Kei a letter and then tells Kei to go on without her and escape the lab now "before he gets you". Kei hesitates at first but then escapes as the lab explodes, leaving Eileen behind. It is unknown what happened to Eileen after the explosion.
Three years after the explosion at the Orion labs, Kei finds out more of her past from the letter Eileen gave her before the incident. She also found out that her DNA was taken for use in several mass-produced clones, which were then infused with Orion's fight data to create the "perfect fighter".
Fast forward to several weeks before Kei’s 20th birthday, several attacks on various martial artists have been reported. All done by people who look remarkably like Kei. Thus, Kei has been blamed for all the attacks, despite having no hand on them. Kei then began to suspect that it had something to do with the “perfect fighter” project that Eileen had mentioned.
Then, on the day of Kei’s 20th birthday, Orion announces the third Sentoki: Global Martial Arts tournament. Kei joins the tournament in order to cleanse her name and find out the truth about the attacks.

A sequel to the game, Sentoki 4, was released in 2009 for the Arcade (System 202: ENDYMION), PlayStation 3 and XBox 360. It featured new characters as well as new gameplay mechanics and stages.
- This is the first ACS arcade game to support their propietary Amaze.net online service. Amaze.net users can use their access card to not just access internet rankings, but also several other Amaze.net exclusive customization items. However, Amaze.net is only available in Japan and other Asian countries like China and South Korea.
- This is the one and only ACS game to be dubbed by a San Francisco-based voice cast.
- Due to the unfortunate circumstances of the death of Kaneto Shiozawa in 2000, shortly after finishing his voice work for Sentoki 2, his role as Kagero was recast to Takumi Yamazaki from this game onwards.
- Although the ranking system of Sentoki 3 more resembles that of Tekken 5 (a more straight rank system with no branching), Sentoki 3 actually predates Tekken 5 by one year.
- Sentoki 3 was the first game released for ACS’ NOVA-II arcade board, which is based on heavily modified PlayStation 2 hardware. In contrast, Sentoki 3 Final Tuned was the last game for the NOVA-II, being released in 2007.
- Like “Punchy” in the original Sentoki, several unused data for a character named “El Puma” was found beneath the data for the console versions of Sentoki 3 EVO. By hacking the game data, one can reveal a half-finished character model for El Puma, but he has no portraits or movesets of his own.
- According to concept artworks, the character of El Puma was going to be a luchador. But given the prevalence of the other grapple-based characters in the roster, the staff thought that it was “redundant” to add yet another grappler and thus scrapped the character as a whole.
