This past week, as I've been working my way through Lightning Returns: Final Fantasy XIII, I've noticed the game has -- whether it's minstrels, treasure boxes, or even the crowd at the coliseum -- loads of aural Easter eggs just waiting to be uncovered.
Want to see some of them in action? Check out the video above.
Lightning Returns: Final Fantasy XIII was released on November 21, 2013, for the PlayStation 3 and Xbox 360 in Japan. It will be released in Australia on February 13, 2014.
