I already got the Platinum
Great game though.....
I wanted to Platinum the game, so I went on a no kills or alerts run.
I don't remember killing anyone during my playthrough, but for some odd reason I didn't get the "Pacifist" trophy. So I gave up on the platinum. Not to mention some of the hidden trophies are completely random and almost impossible to get if you don't look them up.
