In last night’s presentation we were introduced do D.D., a wolf puppy Big Boss rescued from the jungle.
After being trained by Ocelot, the wolf will be available as a ‘Buddy’ to accompany Snake on field missions. Details on how that will work it still unknown.
The interest thing is, rescue the puppy is a choice. If you do not fulton it, he will not be raised by ocelot and therefore, the cutscene above will not happen at all, meaning both the cutscene and the wolf are unlockable and shows how the story can be changed by the player’s choices.
