Chou Super Robot Wars M

Chou Super Robot Wars M (超ちょう スーパーロボット 大たい 戦せん Ｍエム) is a crossover mecha tactical role-playing/fighting game developed by B.B. Studio and published by Bandai Namco Entertainment for the PlayStation 4 that was released in Japan on April 20, 2021 and in North America and Europe on October 1, 2021 as part of Super Robot Wars 30th anniversary. The game is a sequel and updated edition of Chou Super Robot Wars Æ that was released the previous year. It is also the fourth game in the Super Robot Wars series to be released in North America after Super Robot Taisen OG Saga: Endless Frontier and the first to be released on Europe.

With an extensive budget of ¥2,000,000,000 ($18,260,000), both games in the Chou Super Robot Wars brand were a commercial and critical success, having shipped 800,000 units in the first month of Japanese release and sold a combined 9 million by the end of the year, being two of the highest-selling games in the Super Robot Wars franchise.

The "M" in the title stands for Millennium or Multiverse and the game's catchphrase is “Transform the multiverse for a new millennium.” (新あ たな 千年紀ミレニアム のために 多元世界マルチバース を 変身トランスフォーム する.)
