Ever since this shit started, we've been trying to figure out how this fucking works compared to the media we consumed, but the progress we had at this point was like clearing a hoarder's den and discovering it was just a fucking room within the Kowloon Walled City in Hong Kong combined with the Underground Catacombs in Paris.
There existed a universal truth that their brains were their critical weakness but with the emergence of Stitchers that could basically turn left-alone deadheads as puppets for a time, the way it should've been working was blurring more and more as we discover more shit that they could do.
But yeah, 99% of the deadheads we encounter would still succumb with a strong enough blow to the head but then again, this was only to the extent of our knowledge and the information shared with us.
'What if there were certain mutations that didn't need the Main CPU or what if there were mutations that were stand-alone puppets who didn't need a master?'
