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 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 seven "secret" projects by Japan's top publishers, Bandai Namco signed a multi-million-yen partnership deal with the aforementioned companies to externally-develop six new AAA games together, operating as either the developer and/or publisher under each of them, with the apparent goal of boosting profits and 8th-gen 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.
