Mega Man X4, known in Japan as Rockman X4 (ロックマンX4), is a 1997 platform game developed and published by Capcom. It is the fourth game in the Mega Man X series and the first game in the series to be released on the Sega Saturn and PlayStation. The two versions were released simultaneously in Japan in 1997. A North America release followed sometime thereafter, while Europe received only the PlayStation version in 1997. Mega Man X4 allows the player to choose between the two mechanoid "Reploids" protagonists at the beginning of the game: X, who uses an arm cannon; or Zero, who wields an energy blade.
