One shot: the groaning, aching slump of an overburdened Big Daddy

More concept art retrospectives from BioShock 2 devs 2K, looking at the development of the sequel's original Big Daddy -- the model that all future Daddy's (ie. the ones you fought in the first game) would be based on.

While I appreciate the less-monstrous utilitarian simplicity of the near-final version at bottom (doubly fitting since you yourself will be playing as this Daddy), I can't get over that wicked titular aching slump of the first version at top left.
