Three weeks has passed since hell spawned upon a fragile Earth. Many lives were lost and many hopes were shattered. Humans now live underground in small colonies to avoid the massive pollution on the bruised planet. X is critically rattled by the last encounter with Sigma, and filled with sorrow due to the loss of Zero, who is MIA.

A reploid researcher named “Gate” explores the crash site of the colony one day and discovers a piece of Zero, which still contains the “virus”. After extracting it from the fragment, Gate’s mind was enthralled with new ideas, new plans, and new devious thoughts.

Meanwhile, a reploid politician named Isoc issues a thorough investigation of the “Zero Nightmare” after witnessing an eerie “ghost” of Zero finish off a damaged mechaniloid which X was fighting.

The goal: to exterminate it for the sake of the reploids. X, outraged by Isoc’s plan, intends to search for the missing Zero himself. Still gripping the Z-Saber, a blue light; X, cuts through the darkness.
