I've just been playing GeoW, and I do think that they can soak up a ridiculous amount of lead (it is probably even worse on instanity), and the only game that I can think of where the standard enemies can sock up a similar amount of lead is Uncharted, but there enemies can be felled with one or two headshots, but you still have to fill up their heads in Gears
So, in what other games can the standard enemies soak up massive numbers of bullets?
