Beating either Mega Man X or Mega Man X 2 is a satisfying feat. Beating them both at once is pretty amazing. Beating them both at once using a single game pad to control both? Well that's just nuts.
And buts is exactly what YouTuber Aura Puffs (via Reddit) seems to be, as not only does he complete both games simultaneously using the same Super Nintendo pad, he beats them both while collecting all X upgrades in each level.
Check out the full nearly three hour run below, or skip to 2:43:15 to see both end bosses exploding at the same time. It's so satisfying.
