Mega Man X4 is a singleplayer side view scrolling platform game developed by Capcom. It is the fourth main entry in the Mega Man X series.

Originally released for the PlayStation and Sega Saturn on August 1, 1997, it was ported to PC by Capcom and released on December 3, 1998, published by Media Kaito in Japan, Capcom Entertainment in North America, Virgin Interactive and AcerTWP in Taiwan.

FMV playback in the game requires the Indeo 5 codec, with alternative codec replacement available for modern operating systems. The game's installer was written for a 16-bit system and doesn't run on a modern OS, requiring workarounds such as running 32-bit InstallShield 3 software to install the game (which doesn't create desktop or start menu shortcuts for the game). The game's framerate is capped at 59 FPS.
