Mega Man X4 Video Walkthrough and Hints (PC)

Mega Man X4 is the fourth game in the Mega Man X series. This game was originally released on July 31st, 1997 for the Sega Saturn in North America. Both the Sega Saturn and PlayStation versions were soon released simultaneously on August 1st, 1997 in Japan. The PC version was released in January 1st, 1998, and has been running in operating systems ever after and including Windows 95. It was part of the Mega Man X Collection for the Nintendo GameCube and PlayStation 2.Following the third defeat of Sigma, Cain Labs issues an initiative to create a supplementary military force to complement the Maverick Hunters. The army, called the Repliforce, is a strict military regime led by General and his second-in-command, Colonel.

Six months following the inception of the group, Cain Labs finds its methods to be ineffective, questionable and potentially dangerous in the Maverick defense. To make matters worse, behind the scenes, General has been meeting with a mysterious figure that plots the Hunters' demise, insinuating that they are a "significant threat" to the Repliforce's jurisdiction.

Mayhem breaks out when the Sky Lagoon, a massive floating city, is sent crashing down onto the city below it, killing millions of civilians, humans and Reploids alike. The game begins in a point where either X or Zero is dispatched to investigate possible causes of the disaster only to become entangled, once again, in a struggle against Sigma to save the world.
