In case the post title didn't make it clear, this is fan-made. Fan-made. Yes Mega Man 11 doesn't exist, but hey, a guy can dream, right?
To honor the Blue Bomber's upcoming 25th anniversary, professional video game composer Xavier "mv" Dang created an entire chiptune soundtrack for a fake "Mega Man 11." Right now, you can tune in to a listening party on his TwitchTV channel. Shortly afterwards, he'll release the album on his Bandcamp page for free download!
All in all, the OST is a true labor of love. If you've got an ear for chiptune music, check it out!
