Mega Man X (after X4 stylized as Megaman X), known in Japan as Rockman X (ロックマンX, Rokkuman X), is a Mega Man series of action platform video games released by Capcom.

Mega Man X plays similarly to its predecessor series Mega Man, but with various new features: X has, by default beginning with X2, the ability to dash along the ground at any time (which is very similar to the original slide move from the original, but with better accurate controlling), cling to walls and Wall Jump, and dash and jump at the same time, increasing his speed in the air. This all gives X more mobility than his Classic counterpart; these modifications make it easier to go through the majority of the game without using any other gun than the default, which is different from previous Mega Man games where players were more inclined to rely on weapons won in previous fights (like Metal Man's infamous Metal Blades) against boss characters in previously conquered stages.
