^ I fail to see where and when it has stated that John has a tumor. Prove it dumbass.
@The Conquerer - You so read the books >O I know cuz I read them too.
To add on to your post:
Master Chief despite what everyone thinks, does not shoot aimlessly. You may see him do that, but that's cuz some idiot is playing a game. Master Chief is a expert in stragetic thinking.
He's been able to single handedly take down 4 "Helljumpers", special ops around the same level (maybe one rank lower) then Snake himself.
Master Chief naturally has enhanced reflexes, strength, speed and agility. Add that to the MJOLINIR suit, he is near indestructible. Just cuz he dies in a game with someone who does not have enhanced reflexes themselves doesn't mean he can die if he had complete control of himself.
Snake cannot break his neck or slit his throat... or anything for that matter. Maybe a snipe shot to the head could kill him, but I highly doubt Snake has precision aiming on a rolling, moving, enhanced human twice as fast as an average human. Plus if he does shoot and misses, snipers tend to leave a trail of smoke behind them due to their speed and the gunpowder. Master Chief could easily located Snake and take him down because once Snake misses, Master Chief will know where he is, approximately. If he blindly shoots the shadows, Snake is bound to have to move and if he does, the radar will show where Snake is.
If Snake does remove Master Chief helmet, what's to stop MC to quickly turn around (enhanced speed and reflexes, remember. He's faster than Snake.) and break Snakes neck? Not much.
I'm not denying Snake is a bad fighter or killer, but he's just a human with no enhanced ability. He's just a special op soldier in the military while MC is beyond that.
Also, this has nothing to do with the games themselves. If you solely base it upon the games without thinking, then you CLEARLY have an extremely biased opinion.
"Oh it's overrated, so MC will lose!"
"Snake can sneak around!" <--- I fail to see where any information about Master Chief's actual and true abilites fall.
