Well, finally.
Been waiting for those bastards to be in a game since Fallout 2.
Too bad they're probably going to be the Hillfolk/Ghosts of OWB.

By the way, from the wikia:
"
Lobotomites are hapless victims of medical experiments performed in the Big Empty. Reduced to savage, gibbering monsters, they are released into the neighboring areas as crude security devices. As their name suggests, they are lobotomized humans. Despite the damage to their brain, they are still strong and agile enough to fight hand-to-hand as well as wield and use firearms. Typically, they have a canvas bag with goggles and leather straps over their heads"

Okay, where did this information come from?
