I still have three to get: the Crushing trophy, the Platinum, and another for killing three with a single explosion (iirc).

I'll get there one day.

:)

No, finish the game on hard, this will earn you the easy silver trophy, normal gold trophy as well as the hard gold trophy and this then unlocks crushing mode. When you finish crushing you earn another gold trophy and if you earned all other trophies you will get your platinum trophy.

I also got my platimum trophy for Uncharted (only game I have which currently has one). I found Crushing to be a lot of fun, I had to rethink some strategies which I used for completing hard.

I had it for a week now :)

Crushing is hard as in the earlier stages... i.e any closed in area like the plane wreck and sewers.  Other than that was pretty easy... well not that easy :P 14 hrs for me on crushing :/

yeah thats gay cause i finished it on normal mode and now i have 2 finish it another 2 times : (

That ones easy, you can get it either in the Planewrecked chapter right after you see the first trap and then there is an area that has a whole bunch of traps. There is a guy with one of those grenade launchers on a roof, if you get up there and use it to slaughter the hordes of pirates that come after you then it shouldn't be a problem.

You can also get it in the "Out of the Frying Pan Chapter" at the begining three guys run out of the building next to a red barrel. If you launch the greade at the barrel just right you get all three in one shot.

I think the first method is easiest.

I got this some time ago. I had to play through three times though since my first crushing run became ineligible for trophies because during it I saved over an old save file.

All the game does is show some obscure symbol on the medal page, I didn't even think about what it meant. So I finished crushing and got nothing and had to do it again. Was not pleased.

But I got through it in a decent 5 and half hours the second time.
