As someone who has platinum'd the first two Uncharted games, I understand the basics such as being extremely patient and trying your best to conserve ammo, but within each game there are severely tough chapters and/or sections to get past, that I wish I was better prepared for.
For those who have gotten through Crushing - which areas are the toughest, and what are the best strategies to employ to get through them? What weapons work the best in these tough areas?
