Platinum #55: Operation Flashpoint: Dragon Rising
Hardcore difficulty wasn't as bad as I thought it would be. 4 of the levels are basically gimme's since one of them is only a couple minutes long and the others are entirely stealth based. Although failing at the end of a long level is quite painful. Happened a few times at the end of mission 3 and mission 9. The fact that you can die from a single bullet makes you so apprehensive to advance but most of the time you're working with a time limit.
