Get hyped, speculate, or whatever. Feel free to discuss Ground Zeroes (if it's still a separate game) here as well.
Read somewhere (maybe his Twitter) that the two still are separate games, but the plot of Ground Zeroes leads into Phantom Pain.
Now I really need to finish Snake Eater...
Also, I've read from David Hayter's Twitter account that he'll sit out of Phantom Pain.
So there is real time day and night transitions, along with selectable missions, hijackable vehicles, and a support chopper with customizable music when it drops in.
This mysterious video came up, don't know who this man is. Maybe it's someone we know?
