Fallout 4 will begin in the Warrens, where you play a sentient raccoon. You have to leave the safety of the Warrens because your brother kept having horrible dreams about machines digging down from the surface to cause death and destruction to everyone you know. Most of the other raccoons in the warrens thought he was crazy, but then one day he vanished without a trace. He returned a month later, babbling something about how he "had proof now" -- but a strange device he was carrying in his paws "came to life" and killed him in front of everyone. Then the noises started -- booming, rumbling noises from above that frightened everyone. Armed only with a series of strange photographs taken by your brother, YOU must go forth into the wasteland to save the warren! OK, this will never happen, but I'd really like to see the sentient raccoons hinted at in Fallout 1 make an appearance someday. And, for that matter, talking deathclaws. Or at least a really old Gorus the Scholar.
