Mega Man X4, originally released in Japan as Rockman X4 , is a video game developed by Capcom. It is the fourth game in the Mega Man X series and the second game in the series to be released on the Sega Saturn and PlayStation. The two versions were released simultaneously in Japan on August 1, 1997. A North America release followed in September, while Europe received only the PlayStation version on October 13, 1997.Critical reception for Mega Man X4 has been generally positive. Critics praised the ability to play as either X or Zero, a concept many found to expand upon the already tired gameplay formula of the Mega Man X subfranchise. In addition to its console versions, the game was released on PC worldwide in 1998 and 1999 and on Japanese mobile phones in 2011 and 2012. It was also included on the Mega Man X Collection, a compilation released in North America on the PlayStation 2 and Nintendo GameCube in 2006.
