Metal Gear Online is now available in Japan, so we can exactly know how much free space we will be required on our PlayStation 4 and Xbox One consoles. According to the Japanese PlayStation Store, the free update is 957.2MB. The update is obviously free and available only to those who have a copy of Metal Gear Solid V: The Phantom Pain. This is the third iteration of Metal Gear Online.
While the PC version will be available in January 2016, PS3, PS4, Xbox 360 and Xbox One users can get their new multiplayer mode in a few hours, specifically tomorrow at Midnight PST, 8am UK and 10am CET based on their location. The current gen versions will support up to 16 players, while PS3 and Xbox 360 won’t go beyond 12 players online in the same session.
