One of the biggest controversies surrounding Metal Gear Solid 5: The Phantom Pain is its ending, or more specifically the lack of it really having a complete one. While some very dramatic things happen, there are some big story points that did not get resolved. Seeing as this would be the last game to be developed by Hideo Kojima, this aggravated a lot of fans.
However, there was some hope that the sketches and ideas for the canceled mission 51 that would have wrapped up more of the story would be released as DLC. Konami has now confirmed that that will not be the case, though, as the official Metal Gear account has responded to fans asking questions about mission 51.
After one fan voiced their frustration with mission 51 being an integral part of the story that was removed, the Metal Gear Twitter account responded with “Mission 51 is additional story content that was cancelled before development finished, but its definitely not the ending.”
The account then goes on to claim that mission 50 was always intended to be the ending of the game, despite previous reports suggesting otherwise.
Finally, when asked if there were any plans to revisit mission 51, they replied with “there are no plans we can speak to.”
This renewed controversy regarding Metal Gear Solid 5’s ending has to do with the upcoming release of Metal Gear Solid 5: The Definitive Experience, which will include new DLC but nothing story related. That new collection that includes Ground Zeroes and The Phantom Pain will launch in October.
