Did you know in Monsoon's battle you can actually parry those wheels of scrap and then cut them down to size? once you do that he'll skip the scrap wheel and get back to the melee.
On second thought, I gonna go with Remorse on this one. Even Armstrong was spilling that bluish white blood and he's nowhere even near the cyborg Sundowner or Monsoon was.
it's the Japanese version they couldn't have red blood in the Japanese-Version it needed to be "censored" in some way this is also the reason why Raiden's blood was white in MGS 4 for Rising they changed it to red for release outside Japan
So what is canon? Cyborgs have white blood, or red blood? Also, I think the idea that Sam wasnt really augmented would be conveyed much better if you're playing the Japanese version given that hes the only enemy bleeding red.
