Please use the spoiler tags when asking and answering questions! If you don't know how see below.
Whats is the Spoiler Tag?
It masks the text so it cannot be read without highlight the text by selecting it with the mouse.
How to use the Spoiler Tag?
When writing a post click on this icon:
It will insert a pair of tags which you type the message inside. The text will automatically be hidden when you post your message.
What should I hide with the spoiler tags?
I guess common sense will go a long way with this one.
If it is something
directly related to the MGS Story then Tag It!
If it is something like a poster of a sexy lady in a side room somewhere, I don't think that's a spoiler - unless giving the location gives away how the story progresses.
Things like mission objectives, characters names etc Can all ruin the surprise.
Ultimately,
use your judgement, ask yourself if you would have felt a bit annoyed if it was something you would have liked to find out for yourself?
If in doubt, tag it, just in case.
I haven't played/don't remember the story?
No problem, there are apparently flashbacks during the game to recap previous key events.
You can also catch up by watching the rather good Gametrailers.com Retrospective on the whole series here:

And YouTube Videos of the Saga Volume 1 & Volume 2 DVD's that have come with previous games here:
Metal Gear Solid Saga Volume 1 & 2 YouTube Videos, I recommend at least Volume 1 as it gives an intro to the different Snakes.
Additionally, there are a lot of fan websites.
