Mega Man Xtreme 2

Something mysterious is happening on Reploid Research Island. The reploids have stopped functioning.... Their data has been strangely erased. Now the research team is encountering "irregular" Reploids infected with a strange new DNA chip. This strange DNA chip, known as "DNA Soul", replaces useful data with a devastating sigma virus and puts all Reploids in immediate danger. Now it's up to Mega Man X and his comrade Zero to get to the damaged island and find out who is behind the DNA Soul virus.
