something im confused about is quiet's ending. apparently she leaves after mission 41/43, and that wraps up her story permanently? if there are post-game missions, you wouldnt be able to use her, then? dont get me wrong, i have a feeling im gonna use diamond dog and diamond horse like 99% of the time, but still. what are the pros and cons of letting her leave at that point?
and for that matter, what is the multiple endings thing? how do i get all of them?
