Cross Crisis Series

The Cross Crisis Series (クロスクライシスシリーズ) is a crossover series of six collaborative games published by Bandai Namco Entertainment from 2019 to 2022 in cooperation with various Japanese game companies, including Capcom, Sega and Arc System Works and entertainment companies, such as Banpresto, Toei, Toho, and Tsuburaya.

Referring to six "secret" projects by Japan's top publishers, Banpresto and Arc System Works signed a multi-million-yen partnership deal with the aforementioned companies to externally-develop six new AAA games together, three fighting games and three RPGs, operating as either the developer and/or publisher under each of them, with the apparent goal of boosting profits and 9th generation hardware sales and showing third-party support in an attempt to restore the popularity of console gaming and reclaim Japan's dominance over the West in the video game industry.

Titles
The following games below are canonical installments of the series released in both marketing and chronological orders.

Development
On May 30, 2018, Tatsumi Kimishima, the CEO of Nintendo, said in an interview that he felt that "the Western gaming industry is becoming more popular worldwide than Japanese gaming". He also expressed his concerns on the "decline of console gaming" in favor of the ever-growing popularity of mobile gaming and the "losings of the Japanese game market to American sources: a major turnaround since the 1983 video game crash". Also, surveys showed that as of the start of summer 2018, Western companies like Rockstar, NetherRealms, Bethesda and Ubisoft were making better and higher-quality games than Japanese-made games.

On December 21, 2018, in an interview with Sam Imbecile, a game developer who had been working in Bandai Namco Games for a year and director of Project X Zone 3, he expressed interest into expanding the story and creating a series behind the game's story. He also stated that he wished to bring the Japanese game industry, as well as console gaming itself, back to its "position of dominance in the entertainment industry in this age of social media to survive, just like the old days".

Reception
With extensive marketing and advertising, the series was an extensive success, with all the games receiving critical acclaim and selling a grand total of $5.3 billion worldwide.
