If I'm not mistaken, Naughty Dog is known to have unique management setup, right? they have 2 director for their game and essentially share responsibilities between gameplay and story.
does Visceral have that kind of co-director setup as well? I wonder if Hennig coming in being used to the way Naughty Dog does thing just clash with the normal way Visceral does thing.
"Visceral" in the Amy Hennig era didn't really have its old staff. She was Creative Director while someone from Halo 4 was Game Director IIRC.
I'm not sure what team structure they had assembled at that point beyond that.
