Well I guess I can put my two cents in because I feel that fanboy is right on alot of things.
MC would be able to detect snake with his radar,but Snake could detect MC as well with his own radar.If snake has Chaff gernades their's a good chance he could scramble MC's radar as well.
While MC's suit might give him advantages in a battle,it's not like Snake has never encountered an opponent with special armor.The red Ninja showed feats of super human strength and agility and Snake was still able to out match him.
It was never specified to were the battle might take place.If this takes place in the Halo universe,I can just imagine Snake giving MC all he can handle using weapons and armor from the Halo game.
While the case has been made that MC's armor is amazing,just as fanboy said,in Halo you can kill other players using the same armor with sniper rifles and shotguns.This would lead me to 2 conclusions.
1.Those basic weapons are armor piercing versions of their conventional weapons
2.The armor has weak spots that even the most conventional of weapons can exploit.
pound 4 pound it seems to me as is if Snakes feats over shadow MC's by leaps and bounds.I will admit I have never read the Halo books,but not one person made a list or posted one thing from these books that seems to out do snake,IMO.
