they seem to be the denizens from the fog in Tranzit, but grown of course.
back on topic though, nah, not picking up any parts has nothing to do with anything.
i failed on my first two attempts before i could buy the last perk -- was always something stupid.
first time i flung myself off the building & ironically Who's Who was the last perk i needed to buy...2nd time i got crushed in the elevator after i had purchased Who's Who & Quick Revive during my first 4 perks. so yeah...def make sure u purchase Quick Revive FIRST, then go down...then your second set of perks, include Who's Who first to be on the safe side in case u go down.
