Project X Zone 3: War of Infinite Worlds

Project X Zone III: War of Infinite Worlds (プロジェクト クロスゾーン ＩＩＩ第三次 ： 無む 限げん 大だい  世せ  界かい の 戦せん  争そ), also called Project X Zone 3, is a 2018 crossover open world action-adventure role-playing video game developed by Monolith Soft for the Nintendo 3DS. It is the third and final installment in the Project X Zone video game series, and counting its updated Nintendo Switch edition, is the first game of the franchise to be released in multiple gaming platforms, as well as the first in the series to have a Mature rating. Though the franchise is primarily a crossover between Bandai Namco Entertainment, Capcom and Sega, Project X Zone III introduces characters from web-series, as well as features guest characters from different franchises.

The title arrived in Japan on June 3, 2018, and was released worldwide in December 25, 2018. A remastered version of the game, titled Project X Zone III: War of Infinite Worlds – Ultimate Edition, was released for the Nintendo Switch in Japan on June 1, 2020 and in North America and Europe on December 15, 2020, with a radical change in gameplay, full mod support, new characters and quests, all seven DLC expansions, and a complete graphical upgrade.

Project X Zone III was met with critical acclaim, with reviewers particularly mentioning the crossover content, story, gameplay, character development and setting. However, the game also generated some controversy, with criticism directed at the game's depiction of women, portrayal of religion, graphic violence, sexual content, disturbing topics present and constant use of profanity. The game shipped over 800,000 copies to retailers within the first week of its Japanese release and sold over five million copies by the end of 2018, making it the best-selling game in the franchise, as well as one of the best-selling video games of the year.

The story of the game would eventually coincide with the events of Chou Super Robot Wars, which was released on the same days as the release of Project X Zone 3's Ultimate Edition. On November 9, 2021, Bandai Namco re-released all three Project X Zone games into one pack called Project X Zone Trilogy (プロジェクト クロスゾーン トリロジー) for the Nintendo Switch.

Gameplay
Much like the previous Project X Zone games, this game allows players to strategically maneuver the character units across a field to battle an enemy. Unlike previous its predecessors, Project X Zone 3 removes the linear storyline gameplay and focuses on an open world mechanic, where the player can travel to various alternate Earths in the multiverse, based on different gaming franchises or alternate historical events, to complete quests, enter battles, collect items and weapons, and defeat enemies in battles through the tradition of using pair units and solo units for support in combat. Throughout the game, pair and solo units are unlocked and join the player's team. The game also introduces a drop-in-and-out multiplayer cooperative and online gameplay components.

Other than the new open-world concept, three new gameplay features are introduced: the "Cross-Fusion Multi-Attack", "Unit Classifications" and "Attack Threshold".

Each pair unit or solo unit carries an "Inventory" slot with a maximum capacity of 12 weapons and 100 non-combat items.

The total time length for completion of the game's entire story, including recruiting every playable character and finishing all 110 chapters, is estimated to be around 150-200 hours (or 6 days, 6 hours to 8 days, 8 hours).

Summary
"“And you shall hear wars and rumors of wars. See that you are not troubled, for all these things must come to pass. But that shall not be the end, for nation shall rise against nation, and kingdom against kingdom, and there shall be famines, and pestilences, and earthquakes, in divers' places. All these are the beginning of sorrows. There shall be great tribulation, such as never was since the beginning of the world to this time, nor ever shall be.” —Matthew 24:5-8, 27 Beginning quote for Project X Zone III"

A mysterious massive powerful evil force is sweeping across the corners of the Multiverse without any warning, laying many worlds in ruin. In these sieges, vast multitudes of heroes from many different alternate worlds were either killed or captured and brainwashed to do their enemies' bidding in a pursuit to remove any further resistance to the unknown growing threat entirely. This unholy persecution would be infamously known throughout the game as the “Genocide of Heroes”, a catalyst that would serve as a driving force to the events of the game.

Only now aware of the growing number of ruined worlds and rapidly decreasing number of heroes in the Multiverse, the secret inter-dimensional combat organization Shinra once again acts and investigates matters that caused the Genocide of Heroes, the reason behinds the mass slaughters and the mysterious dark force that does everything horrific at this point behind the scenes.

Eventually, as everything begins to unfold and the truth to unravel, all of the Multiverse is locked in a great war between good and evil that could possibly conclude the eternal strife between light and darkness and bring about the end of all reality as we know it.

Prologue: Beginning of the End
In the beginning of time, a single voice spoke the words: “Let the there be light.” And thus, the universe was created. However, where there should have been one universe, a singularity expanding across all of creation, there were many, a multitude of different realities, in the form of the Multiverse.

In the present time, three years after the events of Project X Zone 2, a black void wall of pure nothingness stretches out across the cosmos. It pervades the Multiverse, consuming entire worlds. On an unknown parallel universe, a mysterious being arrives and is forced to witness the death of multiple worlds in multiple dimensions. He disappears as he is transported elsewhere. Even worse, a series of mass slaughters across many worlds are being investigated with no cause being determined yet. Hundreds of destroyed worlds were also found in the midst of these investigations. A Catholic paladin named Adam Pines was reported about the ongoing crisis and told a group of soldiers to recruit various heroes from all across the Multiverse, saying that “it's time.”

In a parallel universe code-named Earth-1565, a gang of Ouma creatures, unbeknownst to him, coerce the Angry Video Game Nerd, trying to find a job to take a break from his habit of playing horrible games, into joining them and try to target Adam Pines, but the Nerd relents, repels the Ouma and rescues the paladin. In turn, Adam gives him a free privilege to join the Shinra. Meanwhile, the Nostalgia Critic comes across a woman named Chizuru Urashima who hands him over a pamphlet that leads to Shinra Headquarters and disappears after.

Later that day, the Critic and Nerd has a Channel Awesome tenth year anniversary reunion party in New York City with other fellow reviewers, including Linkara, Angry Joe, Cinema Snob, Phelous, MarzGurl, PawDugan, Nostalgia Chick, Benzaie, Bennett the Sage, 8-Bit Mickey and Handsome Tom. Even Chester A. Bum, Bullshit Man and Guitar Guy come in as guests. The party then comes to a halt when the room shakes and the lights go out. A bulletin on the TV claims there is an "alien invasion" and it is the end of the world. Soon after, the Channel Awesome group runs outside and witnesses a massive horde of demons, machines, monsters, aliens and other evil creatures destroying the city and killing everyone on their path. The group barely survives when two mysterious warriors, wearing red and black and armed with swords and guns, arrive, save them and take down the entirely evil army single-handedly.

Adam then appears and joins the group into the Shinra where its central headquarters are located in Roppongi, Tokyo, Japan at Earth-363. When the Nerd arrives at the HQ, while also coming across his childhood rival, the Pretty SEGA Gamer, who is now a marine at Shinra, he is forced to take an exam by Shinra personnel, unknown to them that the Nerd is already recruited. Adam explains to everyone that after the defeat of Byaku Shin and the apparent demise of Ouma, Shinra established various backup bases and headquarters in different parallel universes to further ensure security and peace across the Multiverse, but recently, something was decimating almost all of the Shinra bases without warning, leaving the Earth-363 Base intact as the last bastion of defense and hope. He also states that an interdimensional mass slaughter called the Genocide of Heroes is in full effect, destroying hundreds of worlds and killing or brainwashing countless heroes to the cause of evil forces. That is why 10,000 people from various different universes are to be recruited for the newly-formed Shinra Armed Taskforce and trained vigorously in order to meet the requirements.

The Nerd, Critic and their friends are among the 10,000 who are recruited to be possible soldiers for the Shinra Armed Forces, with the Channel Awesome group being part of Platoon 13 that Adam administers and supervises. Unfortunately, due to their extremely poor performance, especially the Nerd, Critic and the others, Adam's platoon is at risk of being removed. As a result, Adam tries to negotiate with Ouma remnants into an armistice in the hopes of ending conflict between the two rival organizations, but to no avail. Thankfully, the Channel Awesome group decides to train hard and shows their overwhelming improvement over time. However, it is too late as Adam is discharged from duty due to attempting to negotiate with the enemy and Shinra's main force departs for Earth-6556, believing this is where the remnants of the Ouma are stationed, despite Adam's protestations that they are not ready to attack yet and they should wait for the right time. While the Shinra army, which composed of the entire Armed Taskforce, all of the marines and most of the combat forces, searched for enemy forces at the Earth-6556 base, they were ambushed and assimilated by outnumbering Ouma armies. With Shinra apparently in the verge of collapse, Adam and the dissolved Platoon 13, that stayed in the Central HQ and heard the news from survivors, fortify defenses and manage to successfully drive out invading enemy forces. Adam then tasks the group to find more heroes out there that are not victims of the Genocide of Heroes and recruit them once more into the renewed war between good and evil, one that might be the last that will ever be fought…

Good Ending
The Good Ending serves as a canonical ending of the game as it takes place before the events of True Ending: United and is required to earn it to unlock the scenario. The player unlocks it if in Chapter 99, thirty minutes passed and the Anti-God's health is less than or equal to 30% before a cutscene triggers where the Lord God arrives to clash with the Anti-God.

Bad Ending 3
In Chapter 99, if the Anti-God's health is more than 30% before the Lord God arrives, the player will earn the third bad ending.

After the clash of God and Anti-God tore apart the fabric of time and space, Adam, Eve and Isaac wake up and find themselves in Washington D.C. on Earth which looks normal as it should. However, they look up at what appears to be the Lincoln Memorial, only to find that it is now a statue of Satan. A swarm of police officers, soldiers, firefighters, and news reporters swarm and surround the three, all of whom are demons. It is implied that like in the Good Ending, all of reality had been remade to a single Earth, but instead is ruled by Satan's evil and devoid of human life.

True Ending: United
The game's True Ending can only be unlocked when the Good Ending is earned in the previous playthrough. This leads to the real final stage of the game.

He is a six-fingered master paladin and devout Catholic who is an elite member of Shinra and the Generalissimo of the Shinra Armed Taskforce (森羅連隊軍の総督 Shinra Rentaigun no Sōtoku), the military branch of the aforementioned organization. He suffers with a post-traumatic stress disorder after witnessing his parents killed with his eyes and thus, he swore to get revenge against the one who murdered his family.

He would later move on past the guilt of bearing vengeance for his parents' death and become the Supreme Commander of the Army of the Light (光の大軍の最高司令官 Hikari no Taigun no Saikō Shirei-kan) in the final battle between good and evil.

Adam is voiced by Shō Hayami.

Princess Eve Butterfly
Main article: Princess Eve Butterfly Princess Eve Diaz Butterfly (プリンセス イヴ・ディアス・バタフライ Purinsesu Ivu Diasu Batafurai) is a member of the Shinra Armed Taskforce on Adam Pines's behalf and his partner. She was born in her parents' kingdom in the Mewni dimension, but was raised in Roppongi after her home was ruined by demonic forces and her parents went missing. She is an expert mage who holds the Royal Wand, which is her family's heirloom and an adventurer who is both kind and caring, but also reckless and impatient at times.

Eve is voiced by Rie Kugimiya.

Isaac Flynn
Main article: Isaac Flynn Isaac Garcia-Shapiro Flynn (アイザック・ガルシア・シャピロ・フリン Aizakku Garushia Shapiro Furin) is a very skilled inventor and mechanic from the future who becomes stuck in Adam's time period while time-travelling. He is considered the "brains" of the heroes because of his extraordinary intelligence and ability to create impressive machinery in a short period of time, an unlikely feat he inherited from his father.

Isaac is voiced by Yuichi Nakamura.

Pretty SEGA Gamer
Main article: Pretty SEGA Gamer

The Pretty SEGA Gamer (プリティセガゲーマー Puritisegagēmā) is the Angry Video Game Nerd's childhood rival who always competed with him due to the Gamer and Nerd being fans of rival game organizations, SEGA and Nintendo respectively. After the Gamer realized that SEGA discontinued their final console, the Dreamcast, and stopped becoming a big gaming competitor, she was depressed for a while before she was invited to join the Shinra and become a skilled warrior in the process. When the Nerd and the Gamer reunited in the events of the game, their interactions are a bit hostile at first, but their relationship becomes friendlier. Her personality completely contrasts that of the angry, vulgar and ill-tempered Nerd, whereas the Gamer is friendly, well-mannered, kind, cheerful and patient.

The Pretty SEGA Gamer is voiced by Ayane Sakura.

Fauna
Fauna (フォーナ Fōna) is one of the three children of O'ginn, along with her older sister Jordh and younger sister Leukothea. An adorable pink-haired goddess, she has the power to wield elemental powers of lightning. Fauna is kind and generous to everyone, willing to help anyone in need with what she could and fulfill her duties, and dislikes her enemies for their cruelty and sadism against the beauty of nature and innocence of people. She is more caring and protective when her friend Linkara is around, however. She is voiced by Akane Tomonaga.

Jordh
Jordh (ヨルス Yorusu) is the eldest of the three sisters and a hardy, determined and independent warrior who has the power to manipulate elemental fire at her will. Jordh is very strong-willed and serious with her duties as a goddess that she has scorn for even people who slightly make fun of her or those who are mischievous or gun-crazy, especially Angry Joe, whom she extremely hates at first but soon begins to get used and eventually be fond of his actions. She also has a playful and caring side for her friends. She is voiced by Hyō-sei.

Leukothea
Leukothea (レウコテア Reukotea), nicknamed Lea, is the youngest daughter of O'ginn and a very young yellow-haired goddess who is still learning to perform her duties properly and use her elemental powers of ice correctly. Lea wants to join her sisters in the adventure to combat the forces of evil. But since she is still young and inexperienced, she requires supervision and guide from her father O'ginn. Playful and a little immature, Lea can sometimes come off as a bit annoying around her allies and friends, especially to the Cinema Snob, whom she sees like a big brother. She is voiced by Nana Nogami.

O'ginn
O'ginn (オジン Ojin) is the father of Jordh, Fauna and Leukothea and a powerful deity who wields the power to manipulate the earth element at his will. He is very protective of his children, being there when his daughters were in danger and to the point where he refused to let his youngest child, Leukothea join her sisters in their quests to help the Grand Army of the Light, since she is still very young. Eventually, O'ginn allows Lea to join Fauna and Jordh, but he adds that he will supervise her since he doesn't want her to get hurt. O'ginn is extremely serious about his daughters' mission and well-being and dislikes vulgar people, including those who are his allies.

His name is a play on the name of Odin, a god from Norse mythology, and the word djinn, a powerful being from pre-Islamic Arabian mythology, and based from the Japanese words for "great" or "king" and "god" (大神/王神, ōjin). He is voiced by Kiyoyuki Yanada.

Satan
Main article: Satan (Project X Zone 3)

Satan, known as the Dai-Satan (悪魔神王 大サタン Akuma-shinō Dai-Satan, lit. Supreme Dark Lord Great Satan) in the Japanese version and formerly known as Lucifer, is the absolute ruler of all that is evil and demonic in the Omniverse, the supreme master of darkness and death, and the main antagonist of the game. He is the original monarch of evil, whereas other "lesser Satans" and "ultimate evils" of different Earths (such as Mundus from the Devil May Cry universe) are just weaker duplicates to do bidding for the superior original.

Satan is voiced by Masaharu Satō.

Evilina
Main article: Evilina Evilina (イビリナ Ibinira) is the hellspawn daughter of Satan, his right-hand woman and the heiress of Hell known as the Anti-Christ (反世主 Hanseishu). She has both a very sadistic and masochistic personality, taking pleasure in the pain of everyone, including her enemies, her own allies and even herself. She also has a playful and seductive side, occasionally playing dirty tricks with the heroes and even flirting with them, including her eternal rival, Jesus Christ.

Evilina is voiced by Yui Horie.

Scheisse von Arschloch
Main article: Scheisse von Arschloch Scheiße von Arschloch (シャイセ・ヴォン・アーシロック Shaise von Āshirokku) is the head of the European branch of Ouma, with its headquarters located in Berlin, Germany, and leader of the Ouma survivors and remnants, dedicated to resurrecting their fallen leaders Saya, Sheath, Dokumezu, Dokugozu and many more others, which they succeeded, and completing Ouma's goal of spreading chaos everywhere. Years prior, he had a previous feud with Saya and Sheath due to uneasy relationships with the Japanese and American Ouma divisions in the past as a result of his failures in World Wars I and II. He dons a disguise of a dimension-traveling prophet under the name Narutaki (鳴滝 Narutaki) and holds a grudge against Kamen Rider Decade.

Since he is an incredible master manipulator, Scheisse is revealed and known to be the False Prophet (偽預言者 Nise yogen-sha) in Biblical prophecies and the left-hand hand of the Lord of All Evil, Satan, responsible for influencing the population of Earth-777, Adam Pines' native universe, to embrace Islam, the false religion devised by Satan for Evilina to use to exert her power over mankind. With the remaining 100 universes in the Multiverse slowly merging with Earth-777, Scheisse and Evilina use this as an opportunity to expand Satan's empire across all of the worlds.

Scheisse is voiced by Tatsuhito Okuda.

Anti-God
Main article: Anti-God The Anti-God (邪神 Jashin) is the true antagonist and the final boss of Project X Zone 3. The opposite counterpart of God possibly older than existence itself, the Anti-God is a malevolent nigh-omnipotent entity "made of only pure darkness" and the physical embodiment of everything that is evil. It holds absolute control over the Anti-Matter Universe, a void dimension of made of antimatter entirely, and seeks to destroy all of the Multiverse so that only its domain will remain.

After Byaku Shin's defeat at the hands of Shinra in the previous game, the barrier between positive matter and antimatter shatters as a result of the ensuing battle. Because of that, the Anti-God is reawakened and a wave of pure nothingness begins seeping into the Multiverse, consuming many worlds in the process. It is also responsible for indirectly involving various villains in the ongoing chaos, starting the infamous Genocide of Heroes as a prelude of the worst horrors that is to come.

Pair Units
The pair units are controlled by the player by means of travel and combat. The player uses a pair unit to travel to different locations, collect items and weapons, partake on missions and quests and fight on battles. When the pair unit reaches enough experience points, the two characters in that pair unit are leveled up simultaneously.

Characters denoted with (*) symbol are initially an enemy unit.

Solo Units

Genocide of Heroes
Though the Genocide of Heroes is an important factor in the events of the game, the known casualties of this multiversal catastrophe are only revealed through flashbacks, cutscenes or implications.
 * Shulk from Xenoblade Chronicles is implied to have been killed in the Genocide of Heroes. In a cutscene in the beginning of the game, Shulk's damaged Monado lays on the ground surrounded by rubble and flames. Later, it is explained that Shulk's team was ambushed by Metal Face and an army of Mechons, resulting in most of them, including Shulk himself, killed in the process, with Fiora captured to become Nemesis Face again. Dunban barely survived the assault but was severely injured with right arm cut off. After the heroes of Shinra free Fiora, when she reunites with her brother Dunban and realizes what happened to Shulk and the others by seeing his broken Monado, she breaks down crying.
 * In another cutscene in the start of the game, a man and woman who appear to be Jude Mathis and Milla Maxwell from Tales of Xillia are in a field on fire, with the latter lying bleeding and dead and the former heavily injured and facing Scheisse von Arschloch, only to be easily overwhelmed and killed afterwards.
 * It is implied that Lloyd Irving from Tales of Symphonia was murdered as well.
 * Chrom explains that their team was ambushed by Validar and almost all of them were murdered, leaving him, Lucina and Robin as the only survivors. It would be revealed later on that Tiki and Sumia were also survivors.
 * During the Genocide of Heroes in the Sakura Wars universe, while Ichiro Ogami is leading the Imperial Kagekidan in a massive demonic assault on Tokyo and barely survived, Erica Fontaine's Paris Kagekidan did not share the same fortunate outcome however, as most of its members, including Glycine Bleumer, Lobelia Carlini, Hanabi Kitaoji and Coquelicot, were slaughtered, Erica retreating underground, and the French capital in complete ruins.
 * Also in a flashback, in New York, the New York Combat Revue successfully repelled their side of the demon invasion, however Diana Caprice, a member of the Revue, got herself killed while Shinjiro Taiga battled Ranmaru. Overpowered by Ranmaru, the demon then threw a scythe at him to finish Shinjiro off, but Diana got in the way and took the hit. Desperately reaching for her mech, she couldn't move anymore due to her burns and injuries, made worse with her slowly-dying condition prior. Shinjiro went to her side with Diana complaining on why Shinjiro made her fight fate when she really couldn't. Crying out for life, she disintegrated.
 * Goku using Ultra Instinct Chapter 74 save team Teito Kagekidan and Paris Kagekidan
 * DrWily shooting attack weapon MAGMML2 during her Multi Attack
 * June Lin Milliam from Star Gladiator was found to be cruelly ambushed by Black Hayato. After being saved by Shinra, she reveals that Hayato's cover to attack Bilstein alongside his team was blown and was attacked, with Saturn Dyer and Gamof killed, Hayato captured and June barely escaped. Asking Captain Commando for help, he alongside the rest of the Commando Team moved to save Hayato. But it was all a ruse to capture the Commandos instead, as June had been brainwashed from the start. But later, she and Hayato are freed from Bilstein's control and joined the heroes to avenge Saturn and Gamof.

Controversies
Upon the release of the game, Project X Zone 3 was subject to numerous controversies and charges, which multiple instances nearly got the game pulled from further release, especially internationally.

DLC Download Glitch
The first 300 Japanese copies of Project X Zone III had a glitch that if a game owner downloads Project X Zone 3's DLC content into the game before completing the game, it would lead to corruption of all save data on the SD Card. Fortunately, the problem would be patched in later prints and International versions.

Feminist Reaction
One of the two biggest topics of centering on the game's controversy was the portrayal of female characters in the game and their fanservice and alleged oversexualization. Feminist groups and communities accused the game for its supposed sexism but it was still released it in the United States and France. Monolith Soft responded in the Ultimate Edition by giving every female a swimsuit as an alternate costume and animating three more sex cutscenes.

Religious Portrayal
The other mainstream controversy of the game is centered around its portrayal of Christianity and more prominently, Islam.

Christianity
The Roman Catholic Church and some Protestant Christian sects criticized Monolith Soft for their portrayal of Jesus Christ in the game, where He is the leader of the Army of the Light in the game's endgame arc and a playable character, and the in-universe implication that God is not truly all-powerful because He has a dark counterpart (in this case, the Anti-God). They deemed those cases to be against the core concept of Christianity, claimed that the references from the Book of Revelation are inaccurate from the original source and pointed out it is a result of Japan's secular society that allows freedom to even attack religion without consequence.

Islam
Within the first week of Japanese release, Project X Zone 3 was met with especially universally harsh condemnation by the Muslim world and societies for the accusation that they are following what is actually a Satanic death cult forged to destroy Christianity, which on the other hand is a true religion in-universe, and denigration of the Islamic prophet Muhammad.

What was perceived as a sacrilegious attack on Islam resulted in demonstrations and violent protests against the game to break out on August 7, 2018 in Egypt and spread to other Arab and Muslim nations and to some Western and Asian countries. The protests led to hundreds of injuries and over 50 deaths. Indonesian President Joko Widodo called for an embargo against the Japanese government, and Shahid Khaqan Abbasi, Prime Minister of Pakistan, offered a bounty for the killing of Sam Imbecile, the director. The film has sparked debates about freedom of speech and Internet censorship.

A joint committee of the Islamic Society of North America and the French Council of Muslim Faith released a statement, calling it: "“one of the most troublesome medium, relative to Islamophobic potential, that any of us had seen in twenty-five years. It must be emphasized that the main storyline presented the world under the influence of Muslims through the Caliphate and its leader Imam Mahdi who is the husband of the Anti-Christ's character in the game, and implications that the Prophet Muhammad (PBUH) is deceived by Satan into founding Islam by the orders of Satan who takes the guise of Allah (SWT) and that Islam is not a religion of peace. This is precisely the sentiment that fueled centuries of conflict between the Islamic and Christian religions. This is also an accusation rejected by the Roman Catholic Church at Vatican II, and by nearly all mainline Protestant churches in parallel documents. Unless this game's storyline has been altered by Mr. Imbecile, a fringe atheist and avid believer of the zeitgeist theory, Project X Zone 3: War of Infinite Worlds retains a real potential for undermining the repudiation of blasphemous anti-Islam sentiments in favor of the Christian faith and proving that Japanese culture despises religion to the point where their definition of 'freedom of speech' has literally no limits.”"

Trivia

 * The story in Project X Zone 3 is considered by many to be the "darkest and most surrealized" in the Namco Cross series.
 * It is the first game in the Namco Cross series to feature multiple endings.
 * Originally, the number of playable characters was going to be 300, with exactly 100 Pair Units (2 characters each) and 100 Solo Units. However, the final number of characters reached to 105 Pair Units and 110 Solo Units, totaling in about 320 characters, making Project X Zone 3 the game with the largest playable cast before the release of its Ultimate Edition.
 * The game was promoted by members of the Channel Awesome community as part of their 10th anniversary to the point where they also became characters in the game.
 * As part of the Power Rangers' 25th anniversary, in the North American and European release of the game, Bandai Namco changed the names and unmorphed sprites of Super Sentai characters into their Power Rangers counterparts. For example, Burai / Dragon Ranger from Kyoryu Sentai Zyuranger in the Japanese version was changed to Tommy Oliver / Green Ranger from Mighty Morphin' Power Rangers in the localized version, and Captain Marvelous / Gokai Red from Kaizoku Sentai Gokaiger to Troy Burrows / Super Megaforce Red from Power Rangers (Super) Megaforce. Pre-Zyuranger Super Sentai characters like Akaranger, Big One and Red One were unaltered.
 * A reference to the Square-Enix franchise Final Fantasy is made when Kamen Rider Ex-Aid talks about his companion, Kamen Rider Brave and his Gashats Taddle Quest and Taddle Fantasy, with AVGN commenting the latter to be a "Final Fantasy knock-off".
 * It is confirmed that some characters from Final Fantasy and other Square-Enix franchises will appear in Project X Zone 3’s Ultimate Edition.
 * As part of Bandai Namco's 65th anniversary, a remastered version of Project X Zone 3, namely Project X Zone 3 - Ultimate Edition, was released for the Nintendo Switch console first in Japan on June 1, 2020 and elsewhere on December 15, 2020.
