Metal Gear Solid V: The Phantom Pain
Big Boss has a new friend in Metal Gear Solid V: The Phantom Pain, and it's one that he probably won't ever call to chat with on his codec.
Revealed during TGS, it turns out Big Boss can recruit a dog (it might actually be a wolf) named DD (short for Diamond Dog) to his war. You can find a collection of screens with DD in the gallery below. Big Boss finds him as a puppy, and Ocelot can raise and groom him for battle for you.
