Story
AC: Complete contains a considerable amount of new footage that the original version lacks, as well as roughly a thousand revised scenes. This adds a total of 26 minutes to the film. Some of the new scenes include a more in-depth look at the Geostigma, Denzel and Kadaj's origins, as well as an extended fight between Cloud and Sephiroth. The Japanese release of this edition features a new ending track from Kyosuke Himuro called "Safe and Sound", with additional lyrics from My Chemical Romance frontman Gerard Way.
