It's a shame that The Boss had to die at the end in order to complete her mission for the USA. It's no wonder that "Big Boss" would betray his country in later years, after all MGS3 basically amounts to the lot of them being screwed over for ~20 Billion. I'm axious to some day see Metal Gear Solid 4, and I wonder if the aging Solid Snake will himself be,
"Loyal to the end"
Hmm, found a copy of the intro music from Metal Gear Solid 3 posted on YouTube:
It's a bit of a funky track but it kind of grows on you after enough hours of working Snake through the jungle hehe.
