I have the platinum on uncharted and for me the stradegy on the really hard parts is try to hide in different places. The place they put u in to start with in major fights on crushing mode is the worst place to be. Go to a different hiding place. Also anyone with a shotgun is your 1st target cause they can be 30 feet away and still get a 1 shot kill.
My PSN Name is: EvilChronos add me if u want :)
