Marcus;291445 said:From what I understand (or atleast the way they explain it in those campy videos you can watch before playing the game) is that Big Boss created three clones; one of them was perfect, the others would age rapidly. Solidus was the first and weakest clone, followed by Snake, and then Liquid. While they never specifically stated that Snake was made first, it was revealed that Solidus was the oldest and Big Boss constantly berrated Liquid for not being like Solid which makes me picture him as the youngest. That's just my opinion but I think it's pretty reasonable.
Besides, look at him. He was defeated 5 times in fatal accidents and yet he still lives on through someone elses body. Pretty invincible if you ask me.
The Patriots are dead. Otacon revealed that at the end of MGS2. Keep in mind that MGS2 was entirely about mis-information, cloning, and artificial intelligence; the only living member of the Patriots is Ocelot and Liquid (if you count him as living).
Like I said, Liquid lives only because of Ocelot's connection to the dead.
And even though at the end of MGS2 he says they have been dead for whatever amount of years, The developers revealed that The Patriots will be intertwined with MGS4's plot. So I don't know.
