Dead or Alive 4

Dead or Alive 4 has a number of updates in reference to previous titles. New to DOA4 is the introduction of the "Bounce Combo" system. After knocking an opponent to the ground with a strike attack, players can execute a Bounce Combo to perform further attacks on the opponent when they are bouncing off the ground. Low attacks and some mid attacks can now be performed on opponents while they are down.

Certain stages now have moving obstacles that will cause damage to fighters if they are hit by them, and using a counter hold at the right timing can help players avoid being hit by them.

Certain stages now also have obstacles in which fighters can be knocked over them, and when the opponent is on the other side of an obstacle, players can jump over them and they can also perform flying attacks.

New to the game's Online Mode is the introduction of Avatars and Virtual Environments, making it the first fighting game to include these features. Players can customize their Avatars and the environment and furniture in their Lobby. Players can take part in voice or text-based chat with other players while in the Lobby room. Award points are earned from winning online battles and players can use the points to buy accessories for their Avatars and Lobby rooms.

Characters' move lists have been vastly updated and four new characters have been added to the fighting roster, with returns from a couple of past characters as well. The counter system has been tightened, making the window for counters shorter and more difficult to execute, and the amount of damage that counters inflict has been changed. However, like Dead or Alive 3, the game features a relatively low number of costumes (excluding variants), and several characters now had to be unlocked by the player including Helena.

Dead or Alive 4 features a total of 23 fighters, including 22 playable characters and the boss character Alpha-152. Returning characters in the game are Ayane, Bass Armstrong, Bayman, Brad Wong, Christie, Hayate, Hitomi, Jann Lee, Kasumi, Leifang, Ryu Hayabusa, Tina Armstrong, and Zack.

DOA4 features three new playable characters: Kokoro, a young geisha in training; Eliot, a 16-year-old boy from England and protégé to Gen Fu; and La Mariposa, a female Lucha Libre wrestler. In addition, DOA4 features a playable unlockable character from the Halo series, a female Spartan supersoldier going by the name "Spartan-458" (with a Halo-themed stage Nassau Station in the game);^[3] it would later be revealed that her real name would be "Nicole".^[4]

• Alpha-152 ^a, the final stage of DOATEC's human weapon series Project Alpha, created from Kasumi's DNA by the evil scientist, Victor Donovan.
• Eliot, a British xingyiquan practitioner and the only apprentice of the legendary "Immovable Fist", Gen Fu. Having doubts about himself and questioning why Gen Fu chose him as his successor, Eliot enters the tournament to find out if he has the right to carry on Gen Fu's legacy.
• Kokoro, a young Japanese girl currently training to become a geisha. Though she enjoys her lessons, Kokoro's heart and soul truly belong to her bajiquan, and despite the worries of her mother Miyako, she enters to the tournament to test herself.
• La Mariposa, a luchadora who hides her past and true identity underneath her flamboyant costume. La Mariposa rose like a comet to the peak of stardom only a short while after her debut, and has never lost a match.
• Spartan-458 ^{b c d}, real name Nicole, a supersoldier and close-quarters combat practitioner of Microsoft's Halo series. She is the result of the collaboration between Tecmo's Team Ninja and Microsoft's Bungie.

Helena Douglas, daughter of the founder and former chairman of the Dead or Alive Tournament Executive Committee, Fame Douglas, takes over the mantle of DOATEC as its second chairman, determined to fight against the corruption within the enormous organization. After losing both her father and her beloved mother to the darkness of conspiracy, Helena chose to place herself in the middle of the maelstrom in order to put an end to the chain of tragedy once and for all.

The man who holds the true power at DOATEC, Victor Donovan, locked himself in the committee's Bio Lab Core once again to continue coveting his dream of creating the perfect human weapon. His new project, code named "Alpha-152", is the result of the ultimate evolution of hyper-cloning technology, birthed from a DNA sample of Kasumi.

The war between the Mugen Tenshin Ninja Clan and DOATEC continues. During the last tournament, after Ayane successfully defeats DOATEC's last creation, Omega, Hayate returned to the Mugen Tenshin village, taking over the leadership. Now leader, his heart burns with the desire of revenge as he goes on a quest to put an end to DOATEC for the innumerable pain the Mugen Tenshin Ninjas have suffered from the organization. During the fourth tournament, Hayate brought together the most powerful group of ninjas known to man. He is accompanied by Ayane, Ryu Hayabusa, and other members of the Mugen Tenshin; Kasumi, though reluctant and fearing the worst, is dragged into the events herself as she follows her brother.

The forces of Mugen Tenshin launches an assault on DOATEC's primary headquarters, the gigantic 999 meter Tri-tower building. Other competitors such as Brad Wong, Jann Lee, Leifang, Zack, along with newcomers, Eliot and Kokoro, were also among the chaos during the assault. Hayate is approached by a luchadora named La Mariposa who reveals to him about her manipulation of him in coming to destroy DOATEC. Hayate thanks her, stating that she did him a favor, and he battles her to repay her. Hayate later comes across a vengeful Bayman, who vows to finish off Donovan for his betrayal to him. Hayate also states his reasons for wanting revenge on the mad scientist as well. Bayman warns Hayate not to interfere in his plan for revenge, but Hayate states that he can't let him fool things up while the ninjas proceed with their assault. La Mariposa comes across Helena and reveals to her about her involvement in DOATEC's Epsilon project before the second tournament and her reason for Hayate coming to DOATEC. La Mariposa angrily resents Donovan and wants to put an end to all of his motives. Helena reveals to her that stopping Alpha-152 from awakening is now impossible due to her shutdown mechanism being destroyed, and only one option is left to stop Alpha. Kasumi later confronts Helena, telling her to stop the war between DOATEC and the Mugen Tenshin. Helena refuses, stating that Hayate and the others will stop at nothing until DOATEC is destroyed, and she is willing do anything to stop Donovan and Alpha-152 from causing havoc in the world. Helena attempts to shoot Kasumi with a handgun but Kasumi is saved by Hayabusa. Helena later comes across Christie, who reveals that she was her mother's killer. Almost breaking down in sadness over her loss and now boiling with anger, Helena fights Christie.

The ninjas' assault left the Tri-tower building in an inferno, and the buildings' auto-destruct sequence activated by Helena lead to the buildings' ultimate destruction. While the ninjas continue their assault and Kasumi fights Alpha-152, Helena strolls through the burning buildings, reflecting on certain events of her life from childhood into adulthood, leading up to the current events. Helena decides to end her own life, committing suicide by going up to the Tri-tower Heliport between the three buildings and letting herself be consumed by the flames of the burning buildings as Kasumi and Ayane helplessly watch from afar. Suddenly, Zack came flying in with a chopper, saving her before the Tri-tower buildings collapsed to dust.

Although it's by far the series' best entry, DOA4 still boggles the mind with its insanely unbalanced characters and easily exploitable moves."^[14] Matt Conzen of eToychest praised Dead or Alive 4's online mode, calling it "innovative" and how it "fuels the fire that Team Ninja set forth on the Xbox 360 community", calling Dead or Alive "the only console fighting series with a decent online mode", overall calling Dead or Alive 4 "a game that carries the easy to play, difficult to master label, but is well worth mastering in the long run" and how "Dead or Alive 4 is a must play for any fighting game fan".^[28] Play Magazine stated: "They don't make 3D fighters more beautiful and fluid than Dead or Alive 4."^[29] Gamerfeed called Dead or Alive 4 "so close to being flawless it's unbelievable".
