Dead Or Alive: Last Round/DoA Roleplay Adventure Chat Bot ((V.1-0))

Dead or Alive (also known as DOA or DOA1) is the first installment in the Dead or Alive series.

Developed by Team Ninja and published by Tecmo, Dead or Alive was first released in arcades in 1996, using the Sega Model 2 system board and was later ported onto the Sega Saturn home console in Japan on October 9, 1997.

In 1998, a PlayStation version of Dead or Alive was released in Japan, North America, and Europe, with a different graphics and fighting engine, new background music, and two additional characters.

Dead or Alive ++ (デッドオアアライブ++ Deddo oa Araibu Purasu Purasu) was also released in Japan in 1998. This arcade-only release used the Sony ZN-1 arcade board and, while graphically similar to the PlayStation port of Dead or Alive, plays more like Dead or Alive 2. The game introduced a bigger emphasis on stuns and to that end, two separate hold systems were included, one inside and one outside of critical state.

In 2004, the Sega Saturn version was ported onto the Xbox as part of Dead or Alive Ultimate.

Dead or Alive was followed by the series' first sequel Dead or Alive 2 in 1999.

Prologue A girl catches her breath and stares down at the gathering of warrior gods below. What she feels is not light, but darkness. Her mind wanders with thought. She's made it this far... She's traveled this far... on just a few clues... to avenge her brother. The chance for revenge is near.

The insatiable ambition of the human race has lead to the abuse of scientific knowledge. Foolishly setting up the stage for the extreme battle on the land. Now, a new Dead or Alive battle is about to begin.

A girl calmly closes her eyes. She hears the vibration of the colliding power and the uncontrollable, violent melody.

She envisions numerous obstacles set ahead of her. The shadow waves to the courages men and the dignified women.

Kasumi, trusting herself... Throws herself... into the wind. Disappearing, the only thing left, the whistling noise of the wind.

Gameplay The gameplay of Dead or Alive borrows from Virtua Fighter, but makes some key changes that changes the way Dead or Alive is played in comparison to Virtua Fighter. Dead or Alive was unique in its debut in that it featured fairly different choices in gameplay than other 3D fighting games at this time. Its most defining features were its speed and countering system. Dead or Alive put an emphasis on speed and relied more on simplistic commands and reaction time rather than long combo strings. Furthermore, its countering system was the first in the fighting genre to utilize different commands that corresponded to each type of attack.

There are two kinds of holds, an offensive hold (OH) and a defensive hold (DH); furthermore, these commands are executed by holding back or forward on the directional pad along with the guard input to either force away or counter-damage an opponent. Finally, the game used an environmental addition called the danger zone, which surrounded the outer edges of the fighting arena (depending on the options, it could also completely consume it), and when a character came into contact with it, it sent them into the air so the opposing player could execute a juggling air combo. However, this can be avoided with an Ukemi (defensive roll).

During the mid 1990s, Tecmo was in financial trouble. Seeing how popular Sega's Virtua Fighter series was in Japan at the time, the management asked Tomonobu Itagaki to create a game similar to Virtua Fighter. Itagaki stated that he was dissatisfied with the way modern fighting games were presented at the time; he missed the old arcade-style of play and had another vision for the fighting game genre. Having worked for Tecmo for a long time, Itagaki was eventually given the opportunity to develop a fighting game. Itagaki was a fan of Virtua Fighter, but he wanted Dead or Alive to stand out among the competition. This included both an emphasis on being fast-paced and on being provocative.

The first Dead or Alive was released worldwide in 1996 as an arcade game. It was a success in Japan but not in the West. This was possibly due to the competing game Tekken, which was already a popular fighting game series for the PlayStation.

Versions Four different versions of the original Dead or Alive were released:

Arcade version Gen Fu vs. Tina in Dead or Alive for the Arcades. Gen Fu vs. Tina in Dead or Alive for the Arcades.

The original version of Dead or Alive was released in arcades worldwide on November 26, 1996, utilizing Sega's Model 2 arcade board (it was also the first time Sega licensed their hardware to a third-party company; in this case, Tecmo). The game ran on a modified Virtua Fighter 2 engine, featuring eight playable characters with three costumes each, and the boss character Raidou.

Sega Saturn version Hayabusa vs. Lei Fang in Dead or Alive for the Saturn. Hayabusa vs. Lei Fang in Dead or Alive for the Saturn.

It was later ported to the Sega Saturn in Japan on October 9, 1997. The game was never released in North America or Europe. This version added an FMV intro, Time Attack, V.S., Survival, Training and Kumite modes. Unlockables included the ability to play as Raidou, new costumes for each character, and Kasumi's System Voice.

However, this version was downgraded graphically compared to the arcade version. In contrast to the original's fully 3D modeled backgrounds, the Sega Saturn conversion used bitmap tricks and overlapping layers in the same fashion as the Sega Saturn version of Virtua Fighter 2 did. Some details in stages were removed altogether, such as the roof of L's Castle and the swaying bridge in Hayabusa's stage. The characters also had lower-polygon models.

PlayStation version Kasumi versus Zack in Dead or Alive for the PlayStation. Kasumi versus Zack in Dead or Alive for the PlayStation.

On March 12, 1998 in Japan, Tecmo released Dead or Alive for the PlayStation. This version included numerous differences compared to the arcade and Saturn versions; a different graphics engine with Gouraud shading, a revamped fighting engine, new background music, and new stages. Similar to the Saturn version, the stages consisted of 2D bitmaps, but could now extend infinitely (similar to Tekken), which eliminated ring-outs.

The most notable addition was the two new characters; the wrestler Bass who was available from the start, and the unlockable Ayane. It also included more costumes to unlock (only for female characters), Kasumi, and Ayane's System Voices (as "Sakura" and "Wakana", the first names of their voice actors), and additional voice clips.

The PlayStation version was released in North America on March 31, 1998, and later in Europe in July 1998. These versions omitted the text-only epilogues at the end of Arcade Mode.

Dead or Alive ++ Dead or Alive ++ title screen Dead or Alive ++ title screen

The final revision, Dead or Alive ++ was released in arcades in September 1998, running on Tecmo's TPS arcade system (Capcom ZN-1 with custom bios). It is commonly considered a half-step between the first game and Dead or Alive 2. Although aesthetically similar to the PlayStation version, it featured many changes to the gameplay. These changes include being able to position characters before the start of a round, changing most throws to Hold+Punch, and a six-point hold system, the most complex in the series.

Dead or Alive Dead or Alive ++ High Punch Hold 7 / Up-BackHold High Kick 4 / Back4 / BackHold Mid Punch 6 / Forward4 / BackHold Mid Kick 2 / Down1 / Down-Back4 / BackHold Low Punch 2 / DownHold 6 / Forward1 / Down-BackHold Low Kick 2 / Down2 / DownHold This version added a "Tag Battle", although it was more like Team Battle with two characters. Ayane was playable from the start and Raidou could be unlocked fairly quickly. Each character had four costumes, two from the original and two brand new ones. A few of the costumes were exclusive to this version of the game and some were slight recolors.

Dead or Alive 1 Ultimate Gen Fu vs. Kasumi in Dead or Alive Ultimate. Gen Fu vs. Kasumi in Dead or Alive Ultimate.

In 2004, Tecmo released a revamped version of the Sega Saturn port made to run on the Xbox, along with an updated version of Dead or Alive 2. Named Dead or Alive Ultimate, it was basically the original Sega Saturn game ported to the Xbox, making graphics slightly more colorful and smoother, sound from stereo to surround, and adding Xbox Live Online Gaming. The Saturn version was chosen as it was Itagaki's "personal favorite".

Reception In Japan, Game Machine listed Dead or Alive on their January 1, 1997 issue as being the most-successful arcade game of the month. Game Machine also listed Dead or Alive++ on their November 15, 1998 issue as being the eleventh most-successful arcade game of the month.

Although it was not widely distributed in U.S. arcades, Dead or Alive was a commercial success, helping Tecmo pull in a profit of 9.2 million dollars in 1996 and saving the company from bankruptcy.[1] The Sega Saturn version would top the Japanese charts on release, coming in number 1 during Week 41 in 1997.[2] The initial run of 92,000 copies sold out on the day of release.[3] The Saturn version would go on to sell more than 161,000 copies in Japan.[4] The PlayStation version would come in 3rd place during week 11 in 1998, selling over 59,000 copies during its first week and would sell over 74,000 copies.[5] The combined sales of the Sega Saturn and PlayStation versions totaled over 235,000 copies in Japan alone.[4][5]

Upon the game's release in arcades, a Next Generation reviewer commented, "A fighting game that mimics Virtua Fighter 2 in its look and feel to a frightening degree ... Dead or Alive boasts smooth control, crisp polygonal graphics, and an attitude that may enable this game to stand on its own despite its familiar origins." He identified the variety of characters and the danger zones as the game's standout features, and said the tough AI forces players to learn more complex moves and strategies.

The home versions were successful critically as well. Due to the Saturn version's planned (and eventually aborted) releases in the U.S. and UK, it saw a considerable number of reviews in those two countries. Sega Saturn Magazine described Dead or Alive as "An incredible beat 'em up both technically and visually, even getting close to beating Sega's own-brand VF Virtua Fighter games. Computer and Video Games called it "an essential buy for import Saturn gamers", while Next Generation commented, "Dead or Alive is such a polished game that it's surprising to realize this is Tecmo's first 3D fighter. GamePro lauded it for its vast number of moves and throws, and its fast and intense fights.

Praise for the game typically focused on its "hold" mechanic. Next Generation said this mechanic adds a unique tone to the game and blurs the line between offense and defense during fights, replacing the usual fighting game scenario of one character attacking and the other defending with more of a "push-and-pull" struggle for dominance. Electronic Gaming Monthly editor-in-chief John Davison commented that the requisite "use of a character's weight and inertia blazes a trail for other games to follow." One of his co-reviewers, Dan Hsu, said the system of holds and reversals is the best part of the game. GameSpot noted that using holds, "you can counter holds and attacks and then reverse counters on top of that, so you sometimes can get an awesome Jackie Chan-style grappling match that goes back and forth three or four times till someone messes up and pays the consequences.

The "bouncing breast" feature was widely ridiculed for its exaggerated and prolonged animation, which critics regarded as comical and grotesque rather than appealing. Sega Saturn Magazine noted that the breasts "wobble up and down like jellies and seem to operate totally independently to the rest of the girl's body", and Jeff Gerstmann similarly remarked in GameSpot that "They bounce around like gelatin for no apparent reason." He considered it a relief that the feature can be turned off, describing it as "stupid" and "the very definition of overkill." IGN was not as annoyed, but pointed out that the bouncing breasts "don't actually contribute to the gameplay except to add temporary novelty and libido frustration to the typical gamer." Computer and Video Games saw the feature as having a campy appeal, finding humor in how "The slightest movement is enough to set them off, swinging and bouncing around in a most comical fashion!" The reviewer compared it unfavorably to the more realistic breast physics in Fighting Vipers.

A number of reviewers praised the quality of the arcade-to-Saturn conversion, and most applauded this version's high-resolution graphics and detail. However, reviews for the later PlayStation version hailed it as even better, with enhanced graphics and enjoyable new content which adds to the replay value. IGN went so far as to say that "The Model 2 graphics have ported over to the PlayStation better than they've ever been on the Saturn". (Many of the Saturn's killer apps were Model 2 ports, including Virtua Fighter 2.)

GamesRadar included Dead or Alive at number 28 in their list of best Sega Saturn games, stating that "the game's high-speed, rock-paper-scissors style of play was a quick hit with arcade players". In 2011, Complex ranked it as the seventh best fighting game of all time.

In the prototype version, there was a Muay Thai character named Kelly. It is believed that he later became Zack. The photos can be seen here. On the cover of the PlayStation release, Kasumi has white hair. It is unknown why this is. Early posters and screenshots of the game shows Kasumi wearing a red variant of her default costume and without stockings. The name of the training dummy in the Sega Saturn version is "Toreko", as stated in the official guidebook for the game. In the West, it was believed for many years that the training dummy was Ayane due to her having the dummy's bodysuit as a recurring costume in later games, starting off in the PlayStation remake. The English version of Tecmo's official site for Dead or Alive was notorious for largely rewriting the character bios in a way that didn't reflect the actual story, which was often the case for localization at the time.[7] Dead or Alive and Dead or Alive 2 are the only Dead or Alive games to get a rating for general audiences which in Japan, the Saturn version is given an "All Ages" rating by Sega as shown on the top right on the standard edition and bottom left on the limited edition. Dead or Alive 2's rating on the Dreamcast (Japanese) is shown on the back of the case.

Series History: Dead or Alive is set in a world similar to real life, however humanity has an advanced understanding and development in science, where organizations can gain the technology for genetic experiments, and create high-tech weaponry and transport. In addition, traditional and archaic ways of life - such as the ways of the shinobi - are still present in certain places of the world, and supernatural creatures from folklore are real living beings.

The series features a cast of martial artists of various combat styles, nationalities and backgrounds, who take part in a worldwide tournament called the "Dead or Alive World Combat Championship", held by the Dead or Alive Tournament Executive Committee, whose corrupt Head of the Development Victor Donovan secretly uses as a way to find specimen for the creation of "the ultimate fighter" - a humanoid bio-weapon - through genetic experiments.

The main plot revolves around the growing war between DOATEC and the Mugen Tenshin Ninja Clan, who seek to destroy the committee for years of abductions and unwilling experimentation. After the fourth tournament, the rightful Head of DOATEC, Helena Douglas was able to reform the committee, though the feud still continues with Donovan's new organization MIST.

Following the revival of the Ninja Gaiden series in 2004, both Dead or Alive and Ninja Gaiden were given a shared universe with the latter canonically becoming a prequel series to the former.

The Dead or Alive series was created by Tomonobu Itagaki, who is regarded by the game development community for his outspoken and stubborn nature in the development of the series.

Before the release of the Dead or Alive, Itagaki was hired as a graphics programmer for Tecmo in 1992, which was in need of brand of video games to establish a sufficient market. In this vein, Itagaki made a wager with the management of company, particularly the vice president later turned president of the company, Junji Nakarmura, assuring the president he would create a video game that would garner a competent fan base.[4]

Because of the pressure placed on game, Itagaki named it "Dead or Alive" to demonstrate that the company's future rested on the game's success, and proceeded to form a division in the company named "Team Ninja" in 1995 to give Tecmo an identity and be recognized as an elite team.[4]

Itagaki's inspiration for the series would come from Sega's Virtua Fighter series as the management asked Itagaki to create a game similar to Virtua Fighter. Itagaki was a fan of Virtua Fighter, but he wanted Dead or Alive to stand out among the competition. This resulted in an emphasis on being fast-paced and on being provocative, as Itagaki believed entertainment needed both violence and sexuality to truly be entertainment.[4]

The series also derived from the Fatal Fury series from Japan, and the American Mortal Kombat series. During development, he based the game's fast gameplay and sexual appeal from the former, and the series' ability to knock opponents off landscapes from the latter: "I wanted to do something that would attract people's attention as I worked on the DOA game. Of course, DOA is known for its bouncing breasts. Well, I didn't come up with that idea originally. I actually got the idea from one of SNK's 2D fighting games "Garou Densetsu". Of course, when I applied it to a 3D game, it was almost too much for people. And of course, it hurts to fall off from high places in DOA, but the idea came from "Mortal Kombat". In the case of "Mortal Kombat", the 2D fighter, the character falls off and he simply dies. That ends the game. That's it. But we figured it would be more interesting to have the character continue to fight after the fall. And that's what we did..."

On Itagaki's view on how he wished the series to contribute to the fighting genre, he replied: "...I want people to remember DOA as a game that was very aggressive and combative. As to the first question - how it contributed to the fighting genre - I look at it as something similar to how sushi was released in this country and became mainstream. You know, like, some people like graphics, some people like animation, some like flashy character design and so forth. Through DOA, we want to reach out to those people and become somewhat of a mainstream game.

Dead or Alive was released in 1996 as an arcade game worldwide, running on Sega's Model 2 hardware. Dead or Alive was a commercial success, helping Tecmo overcome their financial problems.[4] It was very successful in Japan, but not in the West. This was possibly due to competing against Tekken, which was already a popular fighting game series for the PlayStation.

Dead or Alive was later ported to the Sega Saturn in Japan on October 9, 1997, and an improved version was later released on PlayStation on March 12, 1998. The PlayStation version was later released in North America on March 31, 1998, and later in Europe on July 1998. Tecmo also released Dead or Alive++ for the arcades in Japan, based on the PlayStation version with an even slight updated gameplay that later expanded for the sequel.

Following the success of Dead or Alive, a sequel called Dead or Alive 2 was released for arcades in 1999, running on the Sega NAOMI hardware, and was later ported for the Dreamcast and PlayStation 2 in 2000.

After the arcade release, Team Ninja immediately started working on the console version as Tecmo planned to be listed on the Tokyo Stock Exchange in March 2000. Since the development environment for the Sega Dreamcast was very convenient and the NAOMI hardware being the same as the Dreamcast, the team manage to complete the Dreamcast port in February 2000 as planned.[5]

For the Sony PlayStation 2, Itagaki and his team were only given two months initially to produce the first PlayStation 2 port. Itagaki was greatly disappointed in how the PlayStation 2's development environment was not as convenient as the Dreamcast's and felt that he couldn't complete the PlayStation 2 version as planned in March 2000. Itagaki tried to postpone the game, but Tecmo executives insisted on releasing it on time. At the end of this, one of Itagaki's managers asked to borrow a copy to play, but instead sent it to a production factory. After its release in Japan, the PlayStation 2 version had bugs that could cause crashes, leaving Japanese players disappointed. Itagaki was upset by not being able to finish the game on his own terms and fell into a depression during which he briefly considered quitting the industry.[5]

Dissatisfied with the release versions of Dead or Alive 2, Itagaki and Team Ninja continued enhancing it on both the Dreamcast and the PlayStation markets as they worked towards their vision of the ultimate fighting game. On October 25, 2000, Tecmo released a last major update titled Dead or Alive 2: Hardcore for the PlayStation 2. Even with all the changes, Itagaki was still not happy with Hardcore. He is quoted as saying in the DOA3 booster disc video: "They wanted a launch title in 3 months. I needed 4." Despite this, Dead or Alive 2 was a critical and commercial success, gaining over a profit of $2 million,[4] and all versions of the game combined selling over 1.5 million units worldwide.[6]

Following the success of Dead or Alive 2, the sequel Dead or Alive 3 was released for the Xbox in North America in 2001, and Japan and Europe in 2002.

As Team Ninja where looking to continue the series, Itagaki was approached by Microsoft, offering him a deal to develop Dead or Alive 3 as an exclusive game for their recently announced Xbox console. During the console's development, Microsoft was in need of exclusive, high-profile games to show off the technical capability of their product. Itagaki accepted the offer as he noted how the specs of Xbox were much higher and more powerful than other systems such as the PlayStation 2 and Dreamcast, and the offer fit his design philosophy of always targeting the most powerful console available for the development of the Dead or Alive games. Team Ninja noted how developing solely for one system was easier and how the Xbox's development environment was as convenient as the Dreamcast's, and was much more convenient than the PlayStation 2's.[5][4]

An official arcade release was also planned for the game as Team Ninja looked into utilizing either Sega's NAOMI 2 hardware or their Chihiro hardware that was based on the Xbox's architecture. The official arcade release was eventually skipped due to the arcade's declining popularity in America and Japan.[7][4]

Upon release, Dead or Alive 3 was a critical and commercial success, selling over 1 million units in the first five months and went on to sell over 2 million units worldwide.[4][8][9]

Following the success of Dead or Alive 3, the spin-off game Dead or Alive Xtreme Beach Volleyball was released for the Xbox in 2003.

During Dead or Alive 2's development, the fan base requested Itagaki and Team Ninja add beach volleyball as a mini game since other fighting games had similar mini games. After Dead or Alive 3's release, the staff decided to create the beach volleyball game as a standalone game.[4] Itagaki cited spending time on a beach resort as one of his main inspirations for the game and also cited Final Fantasy X-2 as another inspiration. Itagaki and Team Ninja designed the game exclusively for fans of the series, knowing it wouldn't be understood by others who viewed making things for fans as negative. Itagaki expressed that there wasn't anything wrong with that practice.[10]

Making a traditional sports game was also a big point of contention since the fixed camera was how they made fighting games and the overall goal was to create a game easy to play with cool movements. Only the female characters are playable and the game's development was scheduled after Dead or Alive 3 due to the amount of work required to develop it and the small number of women in the series since having less than 8 playable characters in a game was considered boring.[10]

Dead or Alive Xtreme was later followed by Dead or Alive Xtreme 2, released for the Xbox 360 in 2006, and Dead or Alive Xtreme 3, released exclusively for the Asian market in 2016. According to Amos Ip, the senior vice president of Koei Tecmo, the west currently prioritizes the mainline fighting games over the Xtreme games.

The success of Dead or Alive sparked a renewal interest in Tecmo's classic (but at that time long dormant) Ninja Gaiden series.

After Ninja Gaiden was revived in 2004 by Itagaki and his team, they began linking it back with Dead or Alive, setting the franchises canonically within the same universe with overlapping characters and events. As it was a complete reboot of the series and did not continue the canon of any previous Ninja Gaiden titles, the developers were free to do with the universe and its characters as it saw fit, and so the game was implemented into the Dead or Alive universe, setting up Ninja Gaiden I, Dragon Sword and Ninja Gaiden II as prequels to the first Dead or Alive. In addition, Ninja Gaiden protagonist Ryu Hayabusa, who had already been on the roster of every Dead or Alive fighting game since the beginning, plays a major role in that series' overarching storyline, which has been fleshed out during the development of the subsequent Ninja Gaiden titles.

Having featured Ryu in most of Dead or Alive games during development of the Ninja Gaiden reboot, Team Ninja then included the characters Ayane and Kasumi in most of the Ninja Gaiden games. Conversely, several characters from Dead or Alive have roles in the rebooted Ninja Gaiden series, initially only appearing during story sequences but becoming fully playable characters in special modes in the later games. Rachel and Momiji, characters originating from the Ninja Gaiden series, appear in updated versions of Dead or Alive 5.

After Dead or Alive 4's release, Itagaki stated in 2006 that he had a new Dead or Alive game planned, but in a 2008 interview he said about the series: "This is another area that my closest colleagues and I all agree that we were able to achieve the definitive fighting game with DOA4. So we're not looking to extend the series at this point."

On June 3, 2008, Itagaki announced that he was resigning from Tecmo and was suing the company for withholding a bonus promised for his previous works. He was also filing a lawsuit against Tecmo's new president Yoshimi Yasuda for damages based on "unreasonable and disingenuous statements" made in front of Itagaki's colleagues. Other lawsuits were filed with former president, Junji Nakamura, demanding payment in executive retirement benefits on February 14, 2007, and two plaintiffs suing on behalf of Tecmo's 300 employees for unpaid wages on June 16, 2008.

Itagaki stated that this would unfortunately lead to the end of production for the series. However, Tecmo replied with the announcement that Team Ninja would not be dissolved upon Itagaki's departure, stating that both the Ninja Gaiden and Dead or Alive franchises would remain in production and that some projects were already underway.

Soon after, Tecmo president, Yoshimi Yasuda, resigned from the company following the lawsuits and was replaced by Yasuharu Kakihara. Tecmo would merge with fellow video game publisher, Koei, to form Tecmo Koei Games, now known as Koei Tecmo Games. Yosuke Hayashi was made the new head of Team Ninja while Yohei Shimbori was made director of the series. Dead or Alive 5 was created in partnership with Sega AM2 of Virtua Fighter, featuring several guest characters from that series. Free-to-play versions of the games Dead or Alive 5 and Dead or Alive 6 were release to attract new fans to the series and to introduce more people to the fighting genre, hoping to help to bring back the fighting games' golden era of the 1990s. On March 31, 2021, director Shimbori announced his departure from Team Ninja to pursue other opportunities (later revealed in 2023 to serve as an assistant director for Bandai Namco's Tekken 8[13]) while his position was taken over by Hayashi.[14] In 2022, Hayashi would step down as Team Ninja head to become the Koei Tecmo entertainment division's general manager, with Fumihiko Yasuda serving as Team Ninja's current head.[15] As of 2026, the series continues three decades in, making it one of the longest-running fighting game franchises.

The Dead or Alive series focuses on fast-paced gameplay in a three-dimensional playing field. In comparison to other fighting series in its genre, such as Virtua Fighter, the series places emphasis on striking characters quickly and efficiently. There is an emphasis on "juggling", since countering and fast recovery times make striking risky at times, which prevents slow, technical sets of moves in most instances.

One of series' most innovative additions to the genre is its countering system, officially known as the Triangle System. Beginning from the original Dead or Alive, players could input a backwards directional input in co-operation with the respective guard button to defend against a character's attack while dealing significant damage to the victim's life bar. Counter holds must be timed correctly with an attack, and also must be executed correspondingly with the area of attack. For example, a character that successfully counters a low kick attack from another player must time the input as well as place a downward directional push on the joystick.

The series is also known for its environmental hazards, known as Danger Zones. Fighters can knock their opponents into hazardous areas. Fighters caught in a danger zone take extra damage giving the attacker a slight advantage. These environmental hazards can be anything from falls to explosives to breakable structures.

Like other modern fighting games that attempt to emulate the real life martial arts, the input system in Dead or Alive is modeled on the controls to correspond to the actions being carried out by the avatar; a forward directive punch would most likely be executed with the punch input and the pressing of the directional pad in the appropriate direction.

The series controls also make the instances of speed and simplicity more congruent with the focus of timing and combos in mind, as the commands for basic attacks are widely considered more straightforward than most video games. There is only one button for punch, kick, throw and guard, with the player rarely having to combine more than two different input schemes together at a time. There is a general "rock-paper-scissors" element to the game and essentially boils everything down to timing and ability to read the enemy's style.

In Dead or Alive 2, the series implemented its tag fighting system, allowing characters to switch back and forth for combo attacks and even attack simultaneously when timed correctly. The tag mode also included special throws unique to certain pairs of characters and allows for the participation of four players, something not common in the genre. Dead or Alive 3 introduced Attack Change, a feature in the tag battle mechanics where the fighting character can switch places with a partner, in which the character jumping in can then unleash an attack at the same time. Since Dead or Alive 3, tag battle can be used in the other game modes.

The Dead or Alive games have been mostly well received. The fighting series has received positive reviews, with Dead or Alive 2 having the highest ratings out of the numbered games, and Dead or Alive 5 having the lowest except its Plus version for the Vita. Dead or Alive is considered one of the greatest fighting game franchises of all time. The franchise has received numerous awards and many nominations.

Other developers and critics have expressed opinions on the series. Sega developer Katagiri, gave praise to the series, stating that "the uniqueness of the defense and offense mechanics and the original elements of things like the danger zone were enjoyable and gave me an overall image that it was "a series that has evolved in its own way". Namco on the other hand, ran radio commercials insulting the series, prompting creator Tomonobu Itagaki to place Namco's Tekken on his dislike list.
