Yea it's the only platinum trophy I have. Only hard part was on crushing that level where you drop down from the plane wreck in that tree. Solid that was.
That bit was easy!!! (Just before the tree traps and you enter the castle!)
I am currently doing it on Crushing and have just reached the bit where you meet people with laser sights. One shot kills, I think, so have to dodge a lot.
I play the game with the "fast motion" filter on and it is much quicker, when you get to a hard bit I turn it off and it becomes easier as you are used to playing fast and suddenly it is slow/normal pace again!
