Mega Man X8

Your quest begins with a war-torn Earth, left in shambles after the fall-out of Sigma's war on the planet. Humankind, planning a mass exodus to the moon, has been mass-producing a new generation of robot to start colonizing it. But Sigma has corrupted their DNA to make them turn on humans. This time, you and your team-mates must head to the moon for an outer-space mission of epic proportions to save mankind.
