Despite some controversy over its length, newly released stealth-action game Metal Gear Solid V: Ground Zeroes has shipped over one million copies worldwide, publisher Konami announced today.

It's unclear how many copies of the game were actually sold. In the United States, Metal Gear Solid V: Ground Zeroes was the sixth best-selling game of the month, outpaced by Dark Souls II, Call of Duty: Ghosts, South Park: The Stick of Truth, Infamous: Second Son, and Titanfall in that order.

The 1 million shipped figure for Metal Gear Solid V: Ground Zeroes refers to the number of physical units sent to retailers, so it obviously does not include sales figures for the digital versions available now for Xbox 360, Xbox One, PlayStation 3, and PlayStation 4.

Konami also announced today a patch and a game update for Metal Gear Solid V: Ground Zeroes. The latest title update, available May 1, will unlock and allow all players to access the Deja vu and Jamais Vu missions, which were previously available as exclusives for PlayStation and Xbox platforms, respectively.

The Deja vu mission is based on events from the original Metal Gear Solid and has you playing a low-polygon Snake. The Jamais Vu mission, on the other hand, references the 1998 game Snatcher. You play as superhuman ninja cyborg Raiden in this content.

As for the Metal Gear Solid V: Ground Zeroes patch, Konami didn't say when it will be available or what issues it will address.

Metal Gear Solid V: Ground Zeroes is available today at retail stores for $30 on Xbox 360, Xbox One, PS3, and PS4, while the digital version sells for $30 on Xbox One and PS4 and $20 for Xbox 360 and PS3. It is a prequel to Metal Gear Solid V: The Phantom Pain, which does not yet have a release date.
