Project X Zone 3: War of Infinite Worlds – Ultimate Edition

Project X Zone III: War of Infinite Worlds – Ultimate Edition (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 アルティメットエディション) is the remastered version of the 2018 crossover video game, Project X Zone III: War of Infinite Worlds, developed in collaboration by Monolith Soft, Banpresto and Obsidian Entertainment for the Nintendo Switch. To celebrate the 10th anniversary of the Project X Zone series, the game was released in Japan on June 1, 2022, and worldwide on December 25, 2022.

In addition to featuring returning and new characters from Bandai Namco, Capcom and Sega franchises, the game introduces guests characters from Arc System Works, Square-Enix, Konami, SNK, Koei Tecmo and Compile Heart.

The game was met with commercial success, selling 2,900,000 units worldwide by the end of the year, and critical praise, noted for its upgraded and improved visuals, gameplay, characterization, story and cinematic quality.

Production
In E3 2019, Sam Imbecile announced that a remastered version of Project X Zone 3 will be released in the following year for the Nintendo Switch and will feature plenty of changes from the original handheld version. Also, he announced that he will not return for a sequel and that it will be the last entry of the Project X Zone crossover series, since Imbecile had many other ongoing projects and it's unlikely for the franchise to pick up the pace ever since Souichiro Morizumi, the creator of the series, retired from working in Monolith Soft three years prior and the budget that was spent into making the Ultimate Edition (¥300,000,000 or $2,655,300) was thrice the amount when Project X Zone 3 was first developed in 2018.

It was also confirmed that while the story of the game's Ultimate Edition would be largely the same as the original, there would be plenty of retcons and changes to the plot and various storylines due to the addition and debut of many other series into the mix. He also confirmed that all of the remaining characters in the Namco Cross Series that didn't appear in the original will appear in the remastered edition.

Gameplay
As opposed to the Nintendo 3DS, the Ultimate Edition of Project X Zone 3 features a radicalized changed in gameplay. The update removes the tactical turn-based gameplay of the original and replaces it with a more traditional hack-and-slash/beat-em-up third-person shooter orientation with RPG elements adapted straight from the original and 2.5D graphics incorporated into the environments, characters and animations in the same vein as Dragon Ball FighterZ. The game also introduces the use of an avatar character for the play to customize via appearance, abilities and others, interact with several characters, in and out of combat, and even form relationships with some of them in the same vein as a visual novel.

However, some elements from the original version are retained, such as the use of Pair and Solo Units, Mirage Cancel, Cross Fusion Multi-Attacks, open-world multiverse-exploring and quest unlocks.

Trivia

 * The international release of Project X Zone 3 - Ultimate Edition incorporates English voice-overs for the characters and cutscenes, being the first game in the Namco Cross series to having English dubbed voices.
 * The story in the Ultimate Edition has several changes that deviate from the original 3DS version, with many settings, characters and events altered due to addition of new characters and retcons to tie in with the events of the games from the Cross Crisis Series which were released between Project X Zone 3's original and Ultimate Edition release dates.
 * Also, due to roster changes, some of the characters' backstories prior to and during the events of the game are changed too. For example, in the original 3DS version, Kurino Sandra and Sabine from Adventure of Valkyrie were killed during the Genocide of Heroes months before the game's story. In the Ultimate Edition, however, it is retconned that the two actually survived but were brainwashed under Zouna's control.
 * In addition, some characters were included in the game instead of being a casualty in the Genocide of Heroes. For example, Velvet Crowe from Tales of Berseria was originally intended to be killed off prior to the game's events and leave a traumatized Laphicet to be the only survivor. However, due to the popularity of her character and Sam Imbecile's perception that Berseria is his second favorite Tales games after Vesperia, Velvet was instead included in the game.
 * The game is filled with various easter eggs and references regarding technical aspects behind it.
 * As an example, in one scene, Ken Masters from Street Fighter briefly discusses to children about traffic safety. This is a reference to Yūji Kishi's debut role as Kyōsuke Jinnai or Red Racer from Gekisou Sentai Carranger.
 * In another example, Captain Commando and Sailor Pluto's relationship is a reference to the marriage between their respective seiyuus, Ryotaro Okiayu and Ai Maeda. It is also the case with Zero and Iris, with Maeda replacing the late Yuko Mizutani for the role of the latter.
 * A scene of Xiaoyu and Alisa Amiella beating up Ryutaros who is caught peeping at them in a locker room could be a joke to their seiyuus as well.
 * In this game, the female characters from Kuroinu and Taimanin Asagi are wearing redesigned and less revealing attires by Masami Obari.
 * Also, a redesign of the final boss, the Anti-God, by Masami Obari from Chou Super Robot Wars is used here.
 * It is the first game in the Project X Zone series to feature a franchise from a visual novel.
 * This game is dedicated in memory of the late voice actor Unshou Ishizuka.
