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, few 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.

All characters from the original 3DS game will reappear in the Ultimate Edition in addition to new characters from different franchises.

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 Chou Super Robot Wars which was 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.
