I'll go in and get it when I can. Bought the original version years ago, and downloaded the free Gold edition off of PS+ so I can try out the Move features. I'll attempt to get the platinum on that version.
It definitely could have been a difficult plat if the devs wanted too. If they had of included trophies for No Infinite Ammo Professional and SS all Mercs maps, it could have been a really impressive Platinum but they really dropped the ball on that one.
