The ending of the new 'Kingdom Hearts 3' game is so secret it's not even on the disc - players will need to download a patch

Disney/Square Enix

Fans have been waiting for "Kingdom Hearts 3" since 2005.

• Due out January 29th, "Kingdom Hearts III" is one of the most anticipated games of the decade, and the first true sequel in the series since 2005.
• Fans have been waiting for more than 13 years for a true sequel to "Kingdom Hearts 2," and some are worried about spoilers hitting the internet before they get a chance to play.
• Leaked copies of "Kingdom Hearts 3" popped up online more than a month before the game's release, but the director Tetsuya Nomura confirmed that the game's true ending will be added via a downloadable patch on release.

Fans have been eagerly awaiting the arrival of "Kingdom Hearts 3" since 2005, and with the game due out tomorrow, the internet is already rife with videos and details about the game's story. The game's ending however, remains largely unspoiled thanks to some unique efforts from the game's development team.

After leaked physical copies of "Kingdom Hearts 3" appeared online last month, "Kingdom Hearts 3" producer Tetsuya Nomura mentioned that the ending of the game was not actually on the disc. Nomura said the epilogue and secret movie at the end of "Kingdom Hearts 3" were "planned to be released at a later date," quelling concerns that the ending would be posted online ahead of the game's release date.

Instead, the ending will be added to the game as a part of a day-one patch. Once installed, the game will update to include the epilogue and players will be able to enjoy the full "Kingdom Hearts 3" experience from start to finish, complete with the ending. Our Xbox One review copy of "Kingdom Hearts 3" received a patch of 1.8 gigabytes (the game itself is a little less than 40GB).
