If for some reason you don't own either Mega Man 9 or Mega Man 10, you might want to swoop up this sweet little deal. Both games have been dropped to a mere $2.99 on Xbox Live Gold (normally $9.99 a piece) for a limited time.
Of note you can only play them on Xbox 360. Though Microsoft is doubling down on backwards compatibility on Xbox One, Mega Man 9 and Mega Man 10 have yet to make the jump. If you buy them now, though, you'll be ready when the time comes.
