Walkthrough

This walkthrough was written by Brad Russell, also known as "TheGum" on GameFAQS

Just a side note about the opening menu with Snake in the cemetery. You can
wait a while and something does happen, or rather, something doesn't happen.
Just FYI.

Also, maybe it's just on a round 2, but those strange opening skits are on
serveral different channels. Just move around the LS.

Ground Zero

*NOTE: During the brief time you have control, feel free to edit the options in
the pause menu, mainly turning on the subtitles.*

Well, the game starts soon after the many strange company lead-in movies and
the long opening intro scene. Once you have control, briefly press pause to see
where you need to go. Then just go left to crawl under the truck for another
part of the intro scene. Then just walk up the road for more scene. Nope, you
don't get the pleasure of cutscening your way through these guys. Just relax
and run up the road, through the guys and into the doorway on the right. Go
up, jump through the window, then go out into the street, and swing around to
the left to hit the next scene. Be ready for two L1 presses during the next,
long scene.

After the save, be ready for some X presses if you feel like it, a few sets
of them (you can press X quite a number of times when you see the icon).
